The Truth About Programmable Thermostats (And Why You're Probably Not Using Yours Right)

Tue, 28 Apr 2026 10:00:43 GMT

You are not alone in this. Most homeowners with a programmable thermostat use it exactly like a manual one: they set a temperature and leave it there, or they adjust it by hand every time they want a change. That is not wrong, but it misses what the thermostat was actually designed to do. If you want to understand your full setup, our zone control systems page covers how controlled temperature management works across your whole home.

We get it. Nobody hands you a manual when you move in. The thermostat is on the wall and it works, so there is no obvious reason to dig deeper. This post is about getting more out of what you already have.

What a Programmable Thermostat Is Actually Designed to Do

A programmable thermostat lets you set different temperatures for different times of day and different days of the week automatically. The point is to reduce how hard your system works when you do not need the full cooling or heating, without you having to remember to adjust it manually every time you leave or come home.

In coastal South Carolina, where your AC runs heavily from May through September, the difference between a system that runs full tilt all day versus one that eases back when the house is empty can be meaningful on your monthly electric bill. The thermostat is the tool. Most people just never set it up.

The Most Common Mistake: Using It Like a Manual Thermostat

If you have a programmed schedule that runs your AC at 74 degrees all day but you override it manually every morning and every evening, you are defeating the purpose. The thermostat cannot save you money if you are constantly fighting it.

Pick a schedule that actually reflects how you live, program it once, and then leave it alone. Override it when you need to, but let the program run the rest of the time. The consistency is what creates the savings.

Common Programming Mistakes in a Coastal SC Climate

Setting the setback temperature too aggressively. Some homeowners set the thermostat to 85 or 88 degrees during the day when they are out, thinking this saves the most energy. The problem is that bringing a house back from 88 to 74 during peak afternoon heat in a South Carolina summer takes a long time and a lot of energy. The system has to work extremely hard to recover, and in a humid climate, the house can feel uncomfortable for an extended period after you get home. A setback of 4 to 6 degrees is more effective than 14 degrees in this climate.
Ignoring humidity in the equation. Standard thermostat programming advice often focuses only on temperature. In coastal South Carolina, humidity is part of the comfort equation. Letting the house get too warm during the day also allows humidity levels to rise, and bringing the temperature back down does not immediately fix the humidity. This is one reason a whole-house dehumidifier can complement a programmable thermostat in beachfront and coastal properties.
Not adjusting the program seasonally. Your life in April is different from your life in July. If you are home more in summer, your occupancy schedule changes. If you have kids home from school, the house is not empty during the day anymore. Review your program at least twice a year and adjust it to match your actual schedule.
Setting separate programs but forgetting weekends. Most programmable thermostats let you set separate weekday and weekend programs. A lot of people program weekdays carefully and leave weekends on a default or manual setting. If your weekend routine is different from your weekday routine, program both.

Realistic Savings Expectations

Programmable thermostats can reduce your cooling and heating costs, but the savings depend entirely on how well the program matches your actual schedule. If you are home at irregular times or your schedule changes frequently, a programmable thermostat may not save as much as the marketing suggests.

A rough benchmark: a 4-degree setback for 8 hours a day during the cooling season typically produces a modest but meaningful reduction in energy costs. The exact number depends on your home, your system, and how much you were running it before. We would rather give you an honest expectation than a headline number.

When to Consider a Smart Thermostat

If your schedule is irregular, if you want the ability to adjust your home's temperature from your phone when plans change, or if you are managing a rental property remotely, a smart thermostat is worth considering. The main advantages over a standard programmable thermostat are remote access and, in some models, the ability to learn your schedule and adjust automatically.
For vacation rental owners specifically, remote monitoring is genuinely useful. You can see what guests have set the thermostat to, adjust it if it is in a range that could cause system problems, and get alerts if something seems wrong. That visibility has real value when you are not on-site.

We install and configure smart thermostats. If you want to talk through whether one makes sense for your situation, call us. We will give you a straight answer about whether the upgrade is worth it for how you actually live.

The One Thing Most People Skip: Reading the Manual

Every programmable thermostat works a little differently. The steps for setting a schedule on one brand are not the same as on another. The manual is usually short, and following it for 20 minutes will tell you more about your specific thermostat than any general guide online.

If you do not have the manual, the model number is usually on the front of the thermostat or inside the battery compartment. Search the model number and the word manual and you will find it.

What That Puddle of Water Around Your AC Unit Means

Fri, 24 Apr 2026 05:00:06 GMT

Some water around your AC is normal. Some is not. Knowing the difference matters, because ignoring the wrong kind of puddle can lead to water damage, mold, or a system failure at the worst possible time. We get calls about this regularly, especially in spring when systems are running for the first time after months of sitting idle. If you spotted water and found this post, you are asking the right question at the right time. Our residential air conditioning page has more background on how your system works, but let us start with what that water is telling you right now.

The short version: water outside near the outdoor unit on a hot humid day is usually nothing to worry about. Water inside your home near the air handler is a different situation. Let us walk through both.

Why Your AC Produces Water in the First Place

Your air conditioner removes humidity from your home as part of the cooling process. Warm indoor air passes over the cold evaporator coil inside your air handler. The temperature difference causes moisture in the air to condense on the coil, the same way a cold glass sweats on a summer day. That condensation drips into a drain pan below the coil and exits through a condensate drain line, usually to the outside of your home.

In coastal South Carolina, where outdoor humidity regularly sits between 80 and 95 percent in summer, your system pulls a significant amount of moisture out of your home every day. A properly functioning system handles all of that without you ever noticing. The problems start when something in that drainage process goes wrong.

Water Outside Near the Outdoor Unit

Usually normal. On a hot, humid day, it is common to see condensation forming around the base of the outdoor unit or dripping from the refrigerant lines. This is just moisture in the air condensing on the cooler surfaces of the equipment. It is not a leak. It is physics.
Worth watching if it is a lot of water. If there is a significant puddle forming that does not seem proportional to the conditions, or if you notice water pooling in areas it did not before, that can indicate a clogged condensate drain line that is backing up and releasing water where it should not. This is not an immediate emergency outdoors, but it warrants a service call before it becomes one.
Call us if you see ice. Ice on the refrigerant lines or on the outdoor unit is a sign of a frozen evaporator coil. Do not ignore this. Turn the system to fan-only mode and call us. Running a system with a frozen coil can damage the compressor, which is a much more expensive repair than whatever caused the freeze.

Water Inside Your Home Near the Air Handler

This is the scenario that needs immediate attention. Water inside your home near the air handler or dripping from the ceiling near ductwork means something in the condensate system has failed. The drain pan is overflowing, the drain line is clogged, or the pan itself is cracked or rusted through.

Turn your system off. Do not keep running it. A system that is overflowing condensate will keep producing water, and that water will keep going somewhere it should not. Water damage to flooring, ceilings, and walls can happen faster than people expect.

Then call us. This is not a wait-and-see situation. Indoor water from an AC system needs to be diagnosed and resolved before the system runs again.

The Most Common Cause: A Clogged Condensate Drain

The condensate drain line runs from the drain pan below your evaporator coil to the outside of your home. In coastal South Carolina, algae grows fast in warm, moist environments. Without regular maintenance, algae and mildew build up inside the drain line and eventually block it completely.

When the drain is blocked, condensate has nowhere to go. The drain pan fills up. When it overflows, water goes wherever gravity takes it. In a home where the air handler is in a closet or attic, that can mean significant water damage before anyone notices.

Clearing a clogged condensate drain is a straightforward maintenance task. It is also one of the things we check and address during every scheduled service visit. Homeowners on a regular maintenance plan almost never call us with this problem because we catch it before it gets to the overflow point.

Other Causes Worth Knowing

A frozen evaporator coil. A coil that freezes up will produce a large amount of water when it thaws, often more than the drain pan can handle quickly. Frozen coils are usually caused by restricted airflow (dirty filter, closed vents) or low refrigerant. If the system was running and you notice a sudden large amount of water, check whether the coil has iced over.
A cracked or rusted drain pan. The drain pan under the evaporator coil is typically metal or plastic and can crack or corrode over time, especially in the humid coastal environment. A pan that is no longer holding water cannot do its job regardless of whether the drain line is clear.
Low refrigerant. A system low on refrigerant runs at lower pressure and cools the coil to temperatures that cause it to freeze. As with all refrigerant issues, this requires a technician. It is not something homeowners can address themselves, and in a coastal climate where salt air accelerates wear on refrigerant lines, it is worth checking if you are having repeated freezing issues.
Improper installation. A system that was not installed with the correct slope on the drain line will not drain properly regardless of whether the line is clear. If you have had recurring condensate problems since installation, slope may be the issue.

What You Can Check Yourself

Before calling us, two things are worth checking.

First, find your air filter and check whether it is clogged. A dirty filter restricts airflow, which can cause the coil to freeze and lead to the overflow situation described above. If the filter is visibly clogged, replace it and switch the system to fan-only mode for a few hours to allow any ice to thaw before running cooling again.
Second, if you can safely access the drain pan under the air handler, check whether it is full of standing water. A full pan tells you the drain line is blocked or the pan itself is compromised.

Beyond those two things, leave it to us. Refrigerant issues, drain line clearing in hard-to-reach locations, and coil inspections are not DIY territory.

The Coastal SC Factor

We mention this because it genuinely changes the math. The humidity on the South Carolina coast means your system pulls more moisture out of the air than a comparable system inland. More condensate means the drain system works harder. Algae grows faster in the warm, moist environment inside the drain line. Salt air accelerates corrosion on the drain pan.

All of this means that the maintenance interval for condensate system care is shorter here than the generic advice you might find online. Regular service is not optional in this climate. It is what keeps these small issues from becoming expensive ones.

You will not be oversold when you call us. If the fix is simple, we will tell you. If something bigger is going on, we will tell you that too and walk you through your options. We fix things the correct way the first time.

Rest easy knowing our team has been handling exactly this type of problem for the people of Myrtle Beach and Charleston since 1947. We know what these systems deal with in this climate and we know how to fix it.

Why Heat Pump Maintenance is Different From Regular AC Service

Tue, 21 Apr 2026 08:30:05 GMT

Many heat pump owners assume their system gets serviced the same way a standard air conditioner does. Once a year, before summer, and you are done. We understand why that assumption exists. But a heat pump is not the same as an AC system, and treating it like one will cost you down the road. If you want to see what comprehensive heat pump service actually looks like, our heat pumps page is a good starting point.

We have been servicing heat pumps on the South Carolina coast for a long time, and the homeowners who take the best care of their equipment are almost always the ones who understand why it needs that care. So let us walk through this one at a time.

What Makes a Heat Pump Different

A standard air conditioner does one job: it cools your home in summer. In winter, it sits idle. A heat pump does both jobs. It cools your home in summer and heats it in winter by reversing the refrigerant cycle. Same equipment, working year-round in both directions.

That difference matters for maintenance because the system never really gets a break. Your AC rests from October through April. Your heat pump works through all of it. More run time means more wear, more opportunities for small issues to develop, and more reason to stay on top of service.

Think about it like your car. If you drove twice as many miles every year, you would change the oil more frequently. A heat pump is your HVAC system driving twice the miles.

Why Twice-a-Year Service Is the Right Schedule

A heat pump needs service twice a year. Once in spring before the cooling season, and once in fall before the heating season. This is not excessive. It is the correct maintenance interval for a system that runs year-round.

Spring service focuses on the cooling side: refrigerant levels, coil cleanliness, condensate drainage, and overall cooling performance. Fall service focuses on the heating side: defrost cycle operation, reversing valve function, and heating efficiency. Each visit addresses what the system is about to do, not what it just finished doing.

Skipping one of these visits does not mean nothing happens. It means small issues that would have been caught at low cost get time to develop into bigger ones. We have seen this play out too many times to count. A reversing valve that was starting to stick in October becomes a failed heating system in January.

The Reversing Valve: What It Is and Why It Gets Checked

The reversing valve is one of the components unique to heat pumps. It is the mechanism that switches the system between heating and cooling mode. It sits in the refrigerant circuit and redirects flow depending on which mode the thermostat calls for.

Reversing valves wear over time and can begin to stick or fail partially before they fail completely. A partially stuck valve means the system is not fully switching modes, which shows up as reduced heating or cooling efficiency before it shows up as a complete breakdown. Catching this early is the difference between a repair and a replacement in some cases.

This check does not happen in a standard AC tune-up because standard AC systems do not have a reversing valve. It is one of the reasons heat pump service is genuinely different, not just the same service with a different name.

The Defrost Cycle and Why It Matters in Coastal SC

When a heat pump runs in heating mode in cold weather, frost can accumulate on the outdoor coil. The system handles this automatically through a defrost cycle that briefly reverses operation to melt the frost and restore efficiency.

In coastal South Carolina, the combination of mild winter temperatures and high humidity means the defrost cycle runs more frequently than it would in a drier climate. A defrost system that is not functioning correctly will allow frost to build up on the coil, reducing heating efficiency and eventually causing the system to work harder than it should.

Checking defrost operation is part of fall heat pump service. It is not something most homeowners can check themselves, and it is not part of what a standard AC service visit covers.

Dual Coil Maintenance: Twice the Surface Area to Keep Clean

A standard AC system has one main coil that does the work outdoors. A heat pump has two coils that alternate between acting as the evaporator and the condenser depending on the season. Both need to be clean to work efficiently.

In a coastal environment, salt air deposits on outdoor coils over time. Combined with pollen, dust, and debris, a coil that has not been cleaned properly loses heat transfer efficiency. The system has to run longer to do the same job. Longer run time means higher energy bills and more wear on the equipment.

Clean coils are one of the simplest things that keeps a heat pump running efficiently. They also require the right cleaning approach for coastal conditions, which is something we know well from 75 years of working in this environment.

What Happens When Heat Pump Maintenance Gets Skipped

We will be straight with you. Skipping one maintenance visit on a heat pump in good condition probably will not cause an immediate crisis. But it shortens the equipment's life, reduces its efficiency, and increases the chance that something fails at the worst possible time.

Heat pumps are more complex and more expensive than standard AC systems. They deserve the care that matches that complexity. The homeowners who get 15 or more years out of their equipment are almost always the ones on a consistent maintenance schedule. The ones who call us after a mid-winter breakdown and ask why it failed are usually the ones who had not had the system serviced in three or four years.

Making It Automatic So You Do Not Have to Remember

The easiest way to handle heat pump maintenance is to stop trying to remember it yourself. Our VIP Maintenance Club automatically puts you on a twice-a-year schedule. We reach out, we schedule around your availability, and we take care of both visits. You do not have to track it. The system gets the service it needs, and you get the peace of mind that comes with knowing it has been looked after.

Rest easy knowing that when the first serious heat of summer hits, or the first cold snap of winter, your system has been prepared for it.

At Coastal Air Plus, creating lasting relationships is what we are all about. We are not here to sell you a maintenance visit you do not need. Heat pumps genuinely need this service twice a year, and we will tell you the same thing whether you are already a customer or calling us for the first time.

The Coastal SC Heat Pump Maintenance Checklist

Sat, 18 Apr 2026 16:45:01 GMT

Protecting your investment from the Grand Strand’s salt, sand, and humidity.

Living within reach of the ocean means your heat pump works harder and ages more quickly than an inland unit. Follow this checklist to extend the life of your system and keep your energy bills predictable.

�� Monthly DIY Heat Pump Maintenance (The "Homeowner 3-Step")

Consistency here prevents 90% of emergency service calls.

�� Check & Replace Filters: In the South Carolina humidity, dust and pollen turn into a "paste" that chokes your system. Check your filters every 30 days. If they look grey or furry, swap them out.
�� The "Salt Flush" Rinse: Take your garden hose (standard pressure only!) and gently spray down the outdoor condenser unit. Focus on the metal fins. This washes away the corrosive salt crust that "eats" your coils.
�� Vinegar Drain Treatment: Pour 1 cup of distilled white vinegar into your condensate drain line. This kills the algae "sludge" that thrives in Charleston’s humidity, preventing water from backing up into your ceiling. *

�� Seasonal Outdoor Care

Best done in early Spring and late Fall.

�� Clear the Perimeter: Keep at least 2 feet of "breathable space" around your outdoor unit. Trim back any hibiscus, palmettos, or seagrass that can restrict airflow.
�� Level the Pad: Our sandy coastal soil can shift. Ensure the plastic or concrete pad your unit sits on is level so the oil in the compressor stays where it belongs.
�� Check for Pitting: Inspect the copper and aluminum parts for "white powder" or tiny holes—this is a sign of salt air corrosion.

�� Professional Maintenance (The Coastal Air Plus Standard)

Expert-level care twice a year to ensure system longevity.

Spring Performance Visit (Preparing for the Heat)

�� Chemically Clean Coils: We use a specific non-acidic cleaner to remove salt and pine pollen without damaging the metal.
�� Check Refrigerant Levels: In SC, a system that is even slightly "low" will freeze up during a 95-degree August afternoon.
�� Amperage Draw Test: We check the motor’s "heartbeat" to make sure it isn't overworking due to salt-crusted components.

Fall Performance Visit (Preparing for the Damp Cold)

�� Defrost Cycle Test: We force the unit into defrost mode to ensure it won't turn into a block of ice when the humidity drops and the temperature hits 35°F. *
�� Heat Strip Inspection: We test the backup electric heat strips to make sure they work—but also ensure they aren't kicking on prematurely and spiking your bill.
�� Electrical Tightening: Salt air can corrode wire connections. We tighten every terminal to prevent "arch" fires and component failure.

The New Homeowner's First Summer: Don't Make These AC Mistakes

Fri, 17 Apr 2026 06:45:00 GMT

Welcome to homeownership in coastal South Carolina. You picked a great place to live and one of the more demanding climates an AC system will ever face. We have been helping folks figure out their HVAC systems on the South Carolina coast since 1947, and every spring we hear from new homeowners who are heading into their first summer with questions they are not quite sure how to ask.

This post is for you. None of what follows is a judgment. We were all first-time homeowners at some point. These are just the things we wish someone had told us early. You can also explore our residential AC services page any time you want a bigger picture of what your system can do.

South Carolina summers are different from anywhere else. The heat is serious. The humidity is relentless. A coastal home has its own specific demands. Knowing a few basics now will save you real money and a lot of frustration between now and October.

Mistake 1: Assuming the System Does Not Need Maintenance Because It Worked Fine Last Year

This is the most common one we see with new homeowners. You bought the house, the AC was running when you moved in, and it ran fine through the fall and winter. So it should be fine, right?

Your HVAC system is a lot like your car. You take it in for an oil change even when it is running well. You do not wait for a problem. Regular maintenance keeps the system running efficiently, catches small issues before they become expensive ones, and extends the life of the equipment. Skipping it does not save money. It just moves the cost further down the road and usually makes it bigger when it arrives.

If you do not know whether the previous owners had the system serviced, assume it has not been done recently and schedule a visit before summer. Our technicians will check the things you cannot easily check yourself: refrigerant levels, coil condition, electrical connections, condensate drainage, and overall system performance. They take their time and walk you through what they find. That is how we do it.

Mistake 2: Constantly Adjusting the Thermostat

We get it. The house feels warm, so you drop the thermostat to 68. Then it gets cool, so you bump it to 76. Then a family member changes it again. The thermostat becomes a dial everyone fiddles with throughout the day.

Here is what most new homeowners do not realize: your AC system does not work faster when you set it lower. It runs at the same speed regardless of whether the target is 68 or 78. Setting it to 65 when you want 72 does not get you to 72 faster. It just makes the system run longer and work harder than it needs to.

Pick a comfortable temperature and leave it there. Something in the 74 to 76 range is reasonable for a coastal South Carolina summer. If you want to save money while you are away, bump it up by a few degrees rather than turning it off entirely. Coming home to a house that has been sitting at 90 degrees takes a long time and a lot of energy to recover, especially in July.

Mistake 3: Closing Vents in Rooms You Are Not Using

This one sounds logical. You are not using the guest bedroom, so you close the vent to save energy. Reasonable idea. Unfortunately, it does not work that way.

Your HVAC system was designed and sized to push a certain volume of air through the ductwork. When you close vents, that air does not disappear. It still gets pushed through the system, but now it has nowhere to go. Pressure builds up in the ducts, which stresses the blower motor, can cause the evaporator coil to freeze, and actually makes the system less efficient rather than more.

Leave your vents open. If you have rooms that consistently feel too hot or too cold, that is worth a conversation about airflow and duct balance, but closing vents is not the fix.

Mistake 4: Ignoring Warning Signs

New homeowners sometimes do not know what normal sounds like. So when the system starts making a noise that was not there before, or when airflow seems weak out of a vent, or when the house takes longer than usual to cool down, it gets chalked up to the system just being old or the house being different from the last place they lived.

Pay attention to changes. If your system is making a sound it did not used to make, that is worth a call. Banging, grinding, or squealing are not normal operating sounds. If airflow out of a vent seems noticeably weaker than the others, that is a duct or system issue worth looking at. If your energy bills jump significantly from one month to the next without a clear reason, the system may be working harder than it should.

None of these things mean disaster. Some are minor. But catching them early is almost always less expensive than waiting. You will not be oversold when you call us. If something is fine, we will tell you it is fine.

Mistake 5: Not Knowing Where Your Shutoff and Breaker Are

Before summer starts, know two things: where your thermostat is (you probably know this one), and where the breaker for your HVAC system is. Also find the emergency shutoff switch, which is usually a red switch near the air handler that looks like a light switch.

If your system ever starts making a serious noise, if you smell burning, or if something seems genuinely wrong, being able to shut it off quickly matters. This is basic homeowner knowledge that is easy to find out now and very useful to have in an emergency.

While you are at it, locate your air filter. This leads us to the next one.

Mistake 6: Not Changing the Filter

The air filter in your system catches dust, pollen, pet hair, and other particles before they get into the ductwork and the air handler. When it gets clogged, airflow through the system drops. A system struggling to pull air through a clogged filter runs less efficiently, works harder, and puts more wear on the blower motor.

On the South Carolina coast, where salt air, pollen season, and humidity all contribute to what ends up in your filter, the standard advice of changing every three months is a minimum, not a rule. Check yours monthly until you know how fast it loads up in your specific home. A coastal home near the beach can go through filters faster than you would expect.

Filters are inexpensive. Replacing a blower motor because the system has been straining against a clogged filter for six months is not. If you want more detail on filter types and what works best in coastal conditions, our residential maintenance page is a good reference.

Mistake 7: Setting Unrealistic Temperature Expectations

This one is especially relevant for older homes, historic homes in Charleston, and beachfront properties that were not built with the tight construction of modern houses.

Your AC system was sized for your home. It was designed to maintain a temperature roughly 20 degrees below the outdoor temperature on a typical summer day. On a 95-degree day in Myrtle Beach with high humidity, expecting the house to hold 68 degrees while every door to the porch is open is asking more than the system was designed to deliver.

A reasonable goal is 74 to 76 degrees on the hottest days. If your system is running constantly and cannot get the house below 78 degrees when it is 98 outside, that may be the equipment's design limits, not a malfunction. That said, if you had different expectations based on what the home was like when you viewed it, or if performance seems genuinely worse than it should be, call us. We will come take a look and give you a straight answer.

One Thing to Do Right Now

If you have not already, sign up for a maintenance visit before summer. Our VIP Maintenance Club puts you on a regular schedule so this never falls through the cracks. It is the single most useful thing a new homeowner can do for their HVAC system. Your car gets oil changes. Your HVAC system deserves the same attention.

And if you have questions, call us. No question is too basic. We have heard every one of them over the past 75 years and we are genuinely glad to help. That is what neighbors do.

Rest easy knowing that whatever comes up this summer, you have a team in your corner that will be straight with you, show up when they say they will, and fix things the correct way the first time.

At Coastal Air Plus, creating lasting relationships is what we are all about. We are not here to make money off one visit. We want to be your HVAC company for as long as you own that home.

Why Your Beach House Feels Like a Sauna Even With the AC Running

Tue, 14 Apr 2026 08:00:02 GMT

You know the feeling. The thermostat says 72. The AC has been running for hours. But the house feels damp, the air feels heavy, and everyone is uncomfortable. You are not imagining it. This is one of the most common calls we get from beachfront homeowners between Myrtle Beach and Sullivan's Island , and it has a real explanation. Your AC is not broken. It is just doing what AC systems are designed to do, and in a coastal environment, that is not always enough. Our whole-house dehumidifier page covers the solution, but let us walk through why this happens first.

We have been solving this specific problem for homeowners on the South Carolina coast since 1947. Not better than other HVAC companies at everything, just different in that we actually understand what a coastal home deals with. A beach house in Myrtle Beach or on Sullivan's Island is not the same as a home twenty miles inland, and it should not be treated like one.

What Your AC Actually Does With Moisture

Your air conditioner is primarily a cooling system. It removes moisture as a byproduct of cooling, not as its main job. Here is how it works: warm air passes over a cold evaporator coil inside your air handler. That temperature difference causes moisture in the air to condense on the coil and drain out through the condensate line. The air that comes out the other side is cooler and drier.

That process works reasonably well in most climates. In a coastal environment, it runs into a problem.

The moisture load on a beachfront home in South Carolina is not like a typical home. Ocean air carries significantly more moisture than inland air. On a summer day in Myrtle Beach or along the Charleston coastline, outdoor relative humidity regularly sits between 80 and 95 percent. Every time a door opens, every time someone comes in from the beach or the pool, every time the house breathes, that moisture is coming in.

Your AC was sized to cool your home. It was not sized to fight the Atlantic Ocean.

Why Coastal Homes Have It Harder

A few things specific to beachfront properties make this worse than it would be even a few miles inland.

Salt air and coil efficiency. Salt air accelerates corrosion on your AC's evaporator and condenser coils. Corroded coils do not transfer heat as efficiently. A system that is losing efficiency is also losing some of its ability to pull moisture out of the air. This is one reason we tell coastal homeowners that their systems have a shorter effective lifespan than the manufacturer's specs suggest.
Continuous moisture infiltration. Inland homes have humidity spikes. Coastal homes have constant humidity pressure. There is no dry break. The moisture load on a beachfront home on Sullivan's Island or in the Myrtle Beach shore communities is coming in continuously, not in occasional waves.
Building characteristics. Many coastal homes, especially older ones, were not built with the tight envelopes that modern inland construction uses. Beach houses breathe. That is fine for ventilation, but it means outdoor air, and outdoor humidity, gets in more easily.
High occupancy during summer. People add moisture to the air. Breathing, showering, cooking, coming in wet from the pool. A beach house at full summer capacity has a much higher internal moisture load than the same house with two occupants in October.

What High Humidity Actually Does to Your Comfort

This is the part that confuses people. The thermostat says one thing. The body says another. Both are right.

Humidity affects how hot you feel because it interferes with how your body cools itself. When the air is already saturated with moisture, sweat does not evaporate efficiently. Your body's natural cooling system stops working the way it should. A room at 72 degrees and 70 percent humidity feels noticeably warmer than a room at 72 degrees and 50 percent humidity.

There is a concept called the heat index, which is what the temperature actually feels like when humidity is factored in. On a day when the outdoor temperature is 90 degrees and humidity is 90 percent, the heat index can exceed 100 degrees. The same principle applies inside your home when humidity is not controlled.

NOAA publishes heat index data for the South Carolina coast if you want to see exactly how much humidity affects perceived temperature in this region. You can find it at weather.gov . The numbers are not small.

The Other Problem: What Humidity Does to the House Itself

Comfort is one issue. The structure of your home is another.

Persistent high indoor humidity creates conditions for mold and mildew growth. In a coastal home that sees elevated humidity for six or more months a year, mold does not need much encouragement. It grows in wall cavities, under flooring, in closets, and inside the air handler itself if conditions stay damp long enough.

Wood absorbs moisture. Floors warp. Cabinets swell. Doors stick. Paint peels. None of this happens overnight, but all of it happens eventually in a home where humidity is not managed. We have been in plenty of beach houses on the South Carolina coast where the humidity damage was far more expensive to address than a whole-house dehumidifier would have been.

If you own a vacation rental, the stakes are even higher. Guests notice musty smells. They notice damp towels that will not dry. Those experiences show up in reviews.

Why a Whole-House Dehumidifier Is Not an Upsell

We want to be straight with you on this, because it matters. A whole-house dehumidifier for a beachfront home in South Carolina is not a luxury add-on. It is the correct equipment for the environment.

Think about it this way. If you lived in a cold climate, you would have a furnace. Your AC system alone would not handle winter. The climate requires a specific piece of equipment for that condition. Coastal South Carolina has a humidity condition that your AC system was not designed to handle alone. A whole-house dehumidifier is the piece of equipment that addresses that condition.

We would not tell you that you need one if you did not. That is not how we do business. We have served the people of Myrtle Beach and Charleston one customer at a time for over 75 years. We are not going to recommend something just because it adds to a ticket.

How Whole-House Dehumidifiers Work

A whole-house dehumidifier installs alongside your existing HVAC system and connects to your ductwork. It operates independently of your AC. When the AC is running, the dehumidifier supports it. When the AC cycles off, the dehumidifier can continue pulling moisture out of the air.

You set a target humidity level, typically somewhere between 45 and 55 percent relative humidity for comfort. The unit runs as needed to maintain that level. You do not have to think about it.

Compared to portable dehumidifiers, which handle one room at a time and need to be emptied constantly, a whole-house unit treats the entire home and drains automatically. For a beach house of any meaningful size, portable units are a losing battle.

The installation process is straightforward for our team. Our comfort advisors take about 45 minutes to assess your home and ductwork before recommending the right unit for your square footage and layout. You can see more about what we install and how on our whole-house dehumidifiers page .

What This Fixes

Homeowners who add a whole-house dehumidifier to their coastal property typically notice a few things fairly quickly.

The house feels cooler at the same thermostat setting. Because humidity is controlled, the air feels lighter. Many find they can set the thermostat a degree or two higher and be just as comfortable, which reduces the load on the AC and lowers energy bills.
Musty smells go away. The conditions that produce them are gone.
Towels dry. Doors stop sticking. The general dampness that people in beach houses often just accept as normal goes away.
For vacation rental owners, the guest experience improves in ways that show up in reviews. Guests do not know why they were comfortable. They just know they were.

What to Do If This Sounds Like Your House

If you read this and thought about your beach house, your condo, or your rental property, the next step is a conversation. We come out, look at your system and your space, and give you a straight answer about what is causing the problem and what will fix it. No pressure. You will not be oversold.

Rest easy knowing that this is a problem we have solved hundreds of times on the South Carolina coast. We know what coastal homes need and what they do not. If a whole-house dehumidifier is the right answer for your property, we will tell you why and show you what it costs. If something else is going on, we will tell you that instead.

At Coastal Air Plus, creating lasting relationships is what we are all about. That means being honest about what your home actually needs. Simple. Reliable. Coastal Air Plus.

Can Your AC Handle Another South Carolina Summer?

Fri, 10 Apr 2026 10:00:22 GMT

Let's figure this out together.

April is the right time to ask the question, because asking it in July when your system has already quit is a different situation entirely. A few honest answers right now can tell you a lot about whether your AC is going to get you through the season or leave you scrambling in the heat.

This is not a complicated process. Work through the factors below. Be honest with yourself. If the answers are pointing in one direction, we will tell you what that means and what your options are.

Factor 1: How Old Is Your System?

This is the starting point for every assessment we do.

A well-maintained AC system in a standard inland climate can last 15 to 20 years. In coastal South Carolina, the math is different. Salt air accelerates corrosion on coils and refrigerant lines. The heat load runs longer and harder than in most of the country. Humidity puts continuous stress on components. A coastal system that hits 12 to 15 years has done a full working life.

If your system is:

Under 10 years: You are likely in good shape on age alone. Move to the other factors.
10 to 13 years: Pay close attention to the rest of this assessment. Age is not a disqualifier yet, but the other factors matter more now.
14 years or older: You are in the window where replacement is a real conversation, not a distant one. The other factors will tell you how urgent it is.

If you do not know your system's age, check the nameplate on the outdoor unit. The manufacturer date is usually printed there. If you cannot find it, we can tell you when we come out.

Factor 2: How Has It Been Performing?

Not how it performed last October. How it performed last July, when the temperature was in the mid-90s and the humidity was sitting at 80 percent.

Ask yourself:

Did it struggle to keep up on the hottest days? A system that held 75 degrees easily in May but could not get below 80 in August is telling you something.
Are some rooms consistently warmer than others? Uneven cooling is sometimes a duct issue, but it can also mean the system lacks the capacity it once had.
Does it run constantly without reaching the set temperature? This is a sign of a system working harder than it should. In an older unit, it often means efficiency has dropped to the point where the system is running almost nonstop just to keep up.

Performance problems in the heat of summer are the most honest indicator you have. If it struggled last year, it will struggle more this year on a system that is 12 months older and has not been serviced.

Factor 3: What Have Your Energy Bills Done?

Pull up your electric bills from last summer and compare them to two or three summers ago. Same house, same general habits. Are they higher?

Aging systems lose efficiency as components wear. A system running at 60 percent of its original efficiency costs significantly more to produce the same amount of cooling. That difference shows up in your electric bill every month, but it creeps up slowly enough that people often do not notice until they look at it directly.

If your summer energy bills have climbed noticeably without a change in your habits or your household size, your system's declining efficiency is likely the reason.

Factor 4: What Is Your Repair History?

Think through the past three years. How much have you spent keeping this system running?

One repair in three years: Normal. Most systems need occasional work. This is not a red flag.
Two or more repairs in the past two years: Worth paying attention to. The repairs are adding up, and an aging system that needs frequent work is often a sign that more components are approaching the end of their life.
A major repair in the past year (compressor, coil, or refrigerant leak on an R-22 system): This is where the repair-or-replace math gets serious. We covered this in detail in our post on

If you spent significant money on repairs in the past 12 months and the system is more than 12 years old, putting more money into it may not be the smartest financial move. Our post on what happens when you wait too long to replace your AC walks through the repair-or-replace math in detail.

Factor 5: Is It Making Sounds It Did Not Used to Make?

Sounds are one of the most reliable early indicators of a system in decline. Most homeowners notice them and then put them out of their mind.

Banging or clanking: Usually a loose or broken part inside the unit. Do not ignore this. Running a system with a loose component damages other parts.
Grinding: Often a bearing issue in the motor. Left unaddressed, this becomes a motor failure.
Squealing: Belt or bearing wear. Common in older systems.
Clicking at startup or shutdown beyond the normal click: Can indicate a relay or electrical issue.
The system is just louder than it used to be: General wear shows up as increased noise. A system that used to run quietly and now sounds like it is working hard probably is.

If your system is making new sounds, get it looked at before summer. Some of these are minor fixes. Some are warning signs of a larger failure on the way.

Factor 6: Do You Notice Any Smells?

A musty smell coming from your vents usually means moisture is sitting somewhere it should not. This can be a clogged condensate drain, which is a straightforward fix, or it can indicate a more serious issue with your evaporator coil. In a coastal environment with high ambient humidity, keeping the condensate drain clean and flowing is part of routine maintenance.

A burning smell is more serious. Shut the system off and call us. Do not run it.

A sweet or chemical smell can indicate a refrigerant leak. This is also a call-us-now situation, not a wait-and-see.

How to Read Your Results

There is no scoring formula here. This is honest judgment, not a quiz. But here is a practical way to think about what you found.

One or two minor factors: Schedule a maintenance visit. Get the system serviced before summer. A well-maintained system in decent condition has a much better chance of getting through a tough season.
Multiple factors, especially age plus performance plus repair history: You are likely looking at replacement in the near term. The question is whether it happens on your schedule this spring or the system's schedule in July.
Sounds, smells, or a recent major repair on an older system: Do not wait. Call us. These are not factors to monitor through summer.

What to Do Next

If this assessment left you unsure, that uncertainty is worth resolving before June. We can come out, look at your system, and give you a straight answer about where it stands. Not a sales pitch. An honest assessment of condition, efficiency, and what it would take to get you through another season versus what replacement would actually cost.

Our comfort advisors take about 45 minutes with a system when they do a full assessment. They check the things on this list and a few more. You get a clear picture of what you are working with. If your system is fine, we will tell you. If it is not, we will tell you that too and walk you through your options. You can also learn more about our residential air conditioning services or check out the VIP Maintenance Club if your system checks out and you want to keep it that way.

Rest easy knowing a new system installed now means a summer without the anxiety of watching an old one struggle through the worst weeks of the year. That peace of mind has real value, and so does the efficiency difference in your monthly electric bill.

At Coastal Air Plus, creating lasting relationships is what we are all about. We have been doing this for the people of Myrtle Beach and Charleston since 1947. We are not going to tell you that you need a new system if you do not. But we are also not going to let you find out the hard way in August.

The Vacation Rental Owner's Guide to Guest HVAC Complaints (And How to Avoid Them)

Tue, 07 Apr 2026 10:30:00 GMT

A one-star review mentioning a hot room or a noisy AC unit can cost you more bookings than the repair would have cost to prevent. Vacation rental owners know this math. The problem is most HVAC issues do not announce themselves before check-in. They show up at 9 PM on a Saturday in July when you are not on-site and your guests are not happy.

We work with rental property owners across Myrtle Beach and Charleston, and we hear the same complaints about guests over and over. The good news is that most of them are preventable. Here is a breakdown of the most common ones, what causes them, and what to do about them.

Complaint 1: It Is Not Cool Enough

This is the most common call we get from rental owners during peak season, and it has a few different root causes.

Thermostat confusion. Guests unfamiliar with your system may set it to 60 degrees hoping for faster cooling. It does not work that way. The system runs at the same speed regardless of how low the setting goes, and setting it too low can actually cause the unit to freeze up and stop cooling entirely. A simple laminated card near the thermostat explaining how to use the system and what a reasonable temperature range looks like goes a long way.

Undersized equipment. Rental properties, especially beach homes and condos, often have higher occupancy than a typical residence. More people, more appliances running, more doors opening and closing. A system sized for a family of four may struggle when eight guests are running the dishwasher, charging devices, and leaving the sliding door open. If guests consistently complain the home does not cool properly, it is worth having us assess whether the equipment is right-sized for rental occupancy.

A system that is past its prime. An aging unit that keeps up fine in shoulder season may not have enough capacity when it is 95 degrees and the property is fully occupied. If your system is more than 12 years old and you are getting cooling complaints in summer, that is not a coincidence.

The fix depends on the cause. A thermostat guide handles guest confusion. A load assessment handles sizing questions. A replacement conversation is what we have when the system is the problem.

Complaint 2: The House Feels Humid Even With the AC Running

This one is specifically a coastal South Carolina problem, and it is more common in beachfront properties than anywhere else.

Standard AC systems are designed to remove moisture as part of the cooling process, but they have limits. In a coastal environment with high ambient humidity, salt air, and guests constantly coming in from the beach and pool, the system can fall behind. The temperature on the thermostat says 72 degrees but the house feels like 78 because the humidity is not under control.

Guests experience this as the AC not working, even when it technically is. The review says the AC was broken. Your unit was fine. The problem was moisture.

A whole-house dehumidifier installed alongside your existing system solves this. It runs independently of the AC and pulls moisture out of the air continuously. We install these in rental properties across the Grand Strand specifically because of this issue. You can learn more on our whole-house dehumidifiers page . For a rental property, it is one of the highest-return upgrades you can make in terms of guest satisfaction.

Complaint 3: The AC Is Noisy

Banging, rattling, squealing, or a unit that sounds like it is working too hard. Guests notice sounds at night especially, and a noisy system in a bedroom wall or directly outside a window is a guaranteed complaint.

Loose components. Vibration over time loosens panels, screws, and internal parts. A maintenance visit catches these before guests do.

End-of-life compressor sounds. A compressor that is failing often makes a grinding or banging noise before it goes out entirely. If guests are reporting this, get it looked at before the next booking. A failed compressor in the middle of a stay is a much bigger problem than a noisy one.

Normal but startling sounds. Some sounds, like the expansion and contraction of ductwork or the click of a thermostat cycling, are normal but unfamiliar to guests. Again, a simple guest guide explaining what sounds are normal helps manage expectations.

Regular maintenance is what keeps noise complaints low. Systems that are serviced consistently run quieter and last longer. If you are not already on a maintenance plan for your rental property, that is the first conversation worth having.

Complaint 4: Some Rooms Are Hot, Others Are Cold

Uneven temperatures are one of the harder problems to explain to a guest who just wants to be comfortable. The master bedroom is freezing. The back bedroom is stuffy. Nobody is happy.

Duct issues. Leaking, disconnected, or poorly balanced ductwork delivers uneven airflow. Rooms far from the air handler often get less conditioned air. A duct assessment can identify where the system is losing efficiency.

Single-zone systems in multi-room properties. If your rental is a larger home and it runs on a single thermostat, there is no way for the system to treat different areas differently. One thermostat controls everything, and some rooms will always be on the losing end of that equation.

Zone control systems address this directly. They allow different areas of the home to be controlled independently, so the master suite and the back bedrooms are not fighting over the same setting. For rental properties with frequent occupancy complaints about temperature, zoning is often the long-term answer.

The Bigger Picture: Protecting Your Reviews and Your Revenue

Every one of these complaints has a version that ends in a bad review and a version that never gets written because the guest was comfortable the entire stay. The difference is almost always whether the property was maintained proactively or reactively.

Reactive maintenance means you find out something is wrong when a guest tells you. Proactive maintenance means we find it first, before check-in, before the problem shows up in your reviews.

Our VIP Maintenance Club is a good fit for rental properties specifically because it puts us on a regular schedule with your system rather than waiting for a call. We catch the small things before they become the kind of thing guests mention in a review.

We also understand that rental properties have unique timing needs. We work with owners to schedule maintenance visits during turnover windows, not during occupied stays. And when something does go wrong mid-guest, we prioritize emergency service for occupied properties because we know the urgency is different.

Smart Thermostats for Remote Monitoring

If you are managing your rental remotely, a smart thermostat is worth serious consideration. It lets you monitor and adjust the temperature from your phone, see whether guests have set the system to an extreme that could cause problems, and get alerts if something goes wrong.

We install and configure smart thermostats as part of rental property setups. It is a relatively small investment that gives you visibility you would not otherwise have until something goes wrong.

One More Thing: The Guest Guide

A simple one-page guide left in the property explaining how the HVAC system works, what temperatures are reasonable, what sounds are normal, and who to call if something seems wrong handles a surprising number of issues before they become complaints. It does not replace a well-maintained system, but it fills in the gaps that maintenance cannot.

We are happy to help rental owners put together the HVAC section of that guide based on their specific equipment.

At Coastal Air Plus, creating lasting relationships is what we are all about. That includes the rental property owners who trust us to keep their properties running the way they should, season after season. We have been doing this for the people of Myrtle Beach and Charleston since 1947. We understand the Grand Strand rental market and the specific demands coastal properties put on HVAC equipment.

You will not be oversold. You will get honest advice on what your property actually needs. Rest easy knowing our team will handle it the right way the first time.

What Happens When You Wait Too Long to Replace Your AC?

Sat, 04 Apr 2026 10:36:44 GMT

We get it. A new AC system is a real investment, and if the old one is still limping along, it is tempting to squeeze another summer out of it. We hear that reasoning every spring. We are not here to pressure you.

But we want to tell you what happens when the old one finally gives up. We have watched this play out too many times, and it almost never goes the way people hope.

The Story We See Every July

It goes something like this.

A homeowner has a 15- or 16-year-old system. It has had a few repairs over the past couple of years. A capacitor one season, a refrigerant recharge the next. Every spring, the thought crosses their mind: should we just replace it? Every spring, it fires up okay and the decision gets pushed.

Then July hits. South Carolina hits back. And the system, which was already running harder than it should to keep up with the heat and humidity, finally quits.

Now what?

Now you are dealing with no AC during the hottest stretch of the year. You are calling us and every other HVAC company in the area, and you are learning that summer is our busiest season. We work nights and weekends to get there, and we always will. But peak-season availability is real, and urgency makes every part of the process harder.

You are making a major equipment decision under stress, in the heat, with your family uncomfortable. That is not the moment anyone wants to be comparing quotes, thinking about financing, or deciding between equipment options.

We have seen people in that situation pay more than they needed to. Not because anyone took advantage of them, but because rushed decisions rarely lead to the best outcomes.

What Spring Replacement Looks Like Instead

Here is what choosing your timing looks like.

You call us in April. We send a comfort advisor to your home. They sit down with you, walk through your system, and spend about 45 minutes measuring your square footage and rooms to make sure we recommend the right size equipment for your home. They review your ductwork too. Then they walk you through your options without any pressure.

You pick what makes sense for your home and your budget. Installation gets scheduled at a time that works for you. The new system is running before the first real heat of the season.

No crisis. No urgency. No sweating through the decision.

If cost is a concern, we offer financing options that make it easier to spread the investment over time rather than absorbing it all at once.

How to Know If Your System Is Living on Borrowed Time

We are not going to tell you to replace your system if it does not need it. That is not how we operate. We lay out the pros and cons and let you decide. But here are the honest indicators we look at when a customer asks us the repair-or-replace question.

Age. Most AC systems in coastal South Carolina have a realistic lifespan of 12 to 15 years. The salt air, the heat, the near-constant run time from May through September is hard on equipment. A system that is 14 or 15 years old and requiring repairs is a different conversation than one that is 8 years old with its first issue.
Repair frequency. One repair in five years is normal. Two repairs in two years starts to add up. When you are spending several hundred dollars a year to keep an aging system running, the math on replacement looks different.
The refrigerant situation. If your system is old enough to use R-22 refrigerant (also called Freon), it is at least 15 years old. R-22 is no longer manufactured in the U.S. What remains in the supply chain is expensive and getting more so. A refrigerant leak on one of these systems is a serious conversation.
Uneven cooling or persistent humidity. If parts of your home are consistently harder to cool, or if the system runs constantly without making the house comfortable, that is a sign the system is working harder than it should to do less than it used to.
Energy bills creeping up. Aging systems lose efficiency. If your electricity bills are meaningfully higher than they were three or four years ago and your usage habits have not changed, your system may be the reason. Energy Star has useful benchmarks for what a properly sized, efficient system should cost to run.

None of these alone are necessarily a verdict. But if you are checking two or three of these boxes, it is worth having an honest conversation about where you stand.

We have also written about the 3 telltale signs it is time for a new AC if you want to dig deeper into the specific warning signals.

The Repair-or-Replace Math

We walk customers through this regularly. There is no universal right answer, but there is a framework that helps.

Take the age of your system and multiply it by the cost of the repair. If that number exceeds half the cost of a new system, replacement is usually the smarter financial move. It is a rough guide, not a formula, but it is a solid starting point for the conversation.

The other piece is efficiency. A new system will almost always run more efficiently than a 15-year-old one. That difference in your monthly energy bill is part of the math too, even if it is harder to put a number on upfront.

We talk to every customer about their specific situation before making a recommendation. That is what the comfort advisor visit is for. Not to sell you something, but to give you the information you need to decide.

Why April Is the Right Window

We are in April. The weather is mild, your current system is not being pushed hard yet, and summer is still a couple of months out. That is the window.

If your system is 13, 14, or 15 years old and has had repairs in the past couple of years, the question is not really whether it will be replaced. It is when. Spring means you get to choose the when. July means the when chooses you.

If you are not sure whether your system needs a full replacement or just a tune-up first, our post on when to schedule your spring AC tune-up on the Grand Strand is a good place to start.

At Coastal Air Plus, creating lasting relationships is what we are all about. That means telling you the truth about where your system stands. Not pushing you toward a sale you do not need. But also being straight with you when the signs are pointing in one direction.

If your system is in that gray zone, old enough to think about but still running okay, call us. We will come take a look, be honest about what we find, and help you figure out what makes sense. You will not be oversold.

Rest easy knowing we have served the people of Myrtle Beach and Charleston since 1947. You can read what our customers say on our reviews page . We have seen a lot of July emergencies. We would rather help you avoid one.

Hard Water in the Lowcountry: What It Does to Your Pipes and Appliances

Fri, 27 Mar 2026 09:15:02 GMT

If you've noticed white, chalky deposits on your faucets, spotty glasses coming out of the dishwasher, or a film on your shower doors that no amount of scrubbing seems to fix, there's a good chance you're dealing with hard water. It's one of the most common plumbing-related issues in the Charleston , Summerville , Ladson , and greater Lowcountry area, and most homeowners don't realize how much damage it does behind the scenes.

What Makes Water 'Hard'?

Hard water simply means your water supply contains higher-than-normal levels of dissolved minerals, primarily calcium and magnesium. These minerals are picked up naturally as water passes through limestone and other rock formations underground before reaching your home. The U.S. Geological Survey has detailed maps showing water hardness across the country, and the Southeast consistently ranks on the harder side.

The Lowcountry sits on limestone-rich geology, which means the groundwater in many parts of Charleston, North Charleston , Summerville, Ladson, and surrounding communities tends to be harder than average. Municipal water treatment reduces some mineral content, but it doesn't eliminate it entirely. Homes on well water often have even higher mineral concentrations.

What Hard Water Does to Your Home

Pipe Buildup and Reduced Flow

Over years, mineral deposits accumulate inside your pipes, gradually narrowing the opening that water flows through. This is especially common in older galvanized steel pipes but can also affect copper plumbing. The result is lower water pressure, reduced flow at faucets and showerheads, and eventually, complete blockages that require pipe replacement.

Water Heater Damage

Your water heater is one of the hardest-hit appliances. Minerals settle at the bottom of the tank and harden into a thick layer of scale. This sediment acts as insulation between the burner and the water, forcing the heater to work harder and use more energy. You might hear popping or rumbling sounds, which is water trapped under the sediment getting superheated.

Hard water can cut a water heater's lifespan by 25 to 40%. Tankless water heaters aren't immune either. Scale buildup inside the heat exchanger reduces efficiency and can trigger error codes that shut the unit down. The Department of Energy notes that water heating accounts for about 20% of a home's energy use, so efficiency losses add up fast.

Appliance Wear

Dishwashers, washing machines, and refrigerator water dispensers all suffer from hard water. Mineral deposits clog spray nozzles, coat heating elements, and leave residue on dishes and clothing. If your dishwasher leaves white film on glasses or your clothes feel stiff after washing, hard water is the likely cause.

Fixture Damage

Those white and green deposits on your faucets, showerheads, and toilet bowls? That's calcium and lime buildup from hard water. Beyond looking bad, the buildup can damage fixture finishes and clog aerators, reducing water flow.

Signs You Have Hard Water

White or yellowish scale buildup on faucets and showerheads.
Spots or film on dishes and glassware after the dishwasher runs.
Soap that doesn't lather well, or a sticky feeling on your skin after showering.
Stiff laundry, even with plenty of detergent.
Decreased water pressure over time, especially at hot water fixtures.
Frequent water heater repairs or shorter-than-expected water heater lifespan.

What You Can Do About It

Install a Water Softener

A whole-house water softener is the most effective solution for hard water. It uses an ion exchange process to replace calcium and magnesium ions with sodium ions, giving you softer water throughout your entire home. Softened water extends the life of your pipes, water heater, and appliances, and it makes a noticeable difference in how your soap lathers, how your clothes feel, and how your fixtures look. Our plumbing team can size and install the right unit for your household.

Flush Your Water Heater Annually

Even with a water softener, periodic water heater flushing removes any sediment that has already accumulated. For homes without a softener, annual flushing is even more important. It's a straightforward service call that can add years to your water heater's life.

Use Vinegar for Surface Deposits

For existing buildup on fixtures, soaking in white vinegar breaks down the mineral deposits. It's a temporary fix for the symptoms, not the cause, but it keeps your fixtures looking clean between service visits.

Do You Need a Water Softener?

Not every Lowcountry home needs one, but many would benefit from it. If you're seeing multiple signs from the list above, a water test can tell you exactly how hard your water is. We can perform a test during a plumbing inspection and recommend the right size and type of softener for your household.

At Coastal Air Plus, creating lasting relationships is what we're all about. Our plumbers serve homeowners across Charleston , Summerville , Ladson , North Charleston , and the surrounding areas. If hard water is giving you trouble, we'll test it, talk you through your options, and install a solution that fits your budget. No pressure, just honest answers.

SEER2 Ratings Explained: What SC Homeowners Need to Know Before Buying a New AC

Tue, 24 Mar 2026 09:30:05 GMT

If you've started shopping for a new air conditioner or heat pump recently, you've probably noticed that efficiency ratings look different from what they used to. The old SEER rating you might be familiar with has been replaced by SEER2. The numbers are different, the testing method is different, and it can be confusing if nobody explains it in plain English.

Here's what SEER2 means, why it changed, and what rating you should be looking for in South Carolina.

What Is SEER2?

SEER stands for Seasonal Energy Efficiency Ratio. It measures how efficiently an air conditioner or heat pump cools your home over an entire cooling season. The higher the number, the more efficient the system.

SEER2 is the updated version of that same measurement. Starting in January 2023, the Department of Energy changed the testing procedure to more accurately reflect real-world conditions. The new test uses higher external static pressure, which basically means they test the system under conditions closer to what it actually faces when installed in your home with real ductwork.

Because the testing is tougher, SEER2 numbers come out slightly lower than the old SEER numbers for the same equipment. A unit that was rated 16 SEER under the old standard might be rated around 15.2 SEER2 under the new one. The unit didn't get worse. The test just got more realistic.

What's the Minimum SEER2 Rating in South Carolina?

The Department of Energy sets minimum efficiency requirements by region, and the exact numbers vary slightly depending on system type and capacity. South Carolina falls in the Southeast region. For most residential central air conditioners, the federal minimum translates to roughly 14.3 SEER2 (equivalent to the old 15 SEER standard). For heat pumps, you're looking at a similar cooling minimum plus an 8.8 HSPF2 heating threshold. In practice, most equipment sold today meets or exceeds these floors, so anything a reputable dealer offers you should already be compliant.

Any new equipment you purchase today must meet or exceed these minimums. If someone offers you a system that doesn't meet these standards, that's a red flag.

What SEER2 Rating Should You Actually Get?

The minimum is 15 SEER2, but that doesn't mean it's the best value for your home. In South Carolina, where AC systems run 6 to 8 months out of the year, the energy savings from a higher-efficiency unit add up fast.

Here's a general guide:

15-16 SEER2: Meets the minimum. A solid choice if budget is tight. You'll get reliable cooling at a reasonable cost.
17-18 SEER2: A good middle ground. Noticeable energy savings over the minimum, and the equipment tends to be quieter and more consistent.
19+ SEER2: Top-tier efficiency. Variable-speed compressors and advanced humidity control. Best for homeowners who want the lowest possible energy bills and the most precise comfort. These units are especially effective in our humid coastal climate because they run at lower speeds for longer periods, pulling more moisture out of the air.

Does a Higher SEER2 Rating Always Save You Money?

Not always, and here's why: the energy savings depend on how much you use your system and what your electricity rates are. A homeowner in Myrtle Beach who runs their AC from April through October will see bigger savings from a high-efficiency unit than someone who only uses AC for three months a year.

The payback period, how long it takes for the energy savings to cover the higher equipment cost, typically ranges from 5 to 8 years for a jump from 15 SEER2 to 18+ SEER2 in South Carolina. Given that most systems last 12 to 18 years, the math works out favorably for higher-efficiency equipment in our climate.

What About Federal Tax Credits?

This is where it gets even more interesting. Under the Inflation Reduction Act, homeowners can claim up to $2,000 in federal income tax credits for qualifying heat pump installations. To qualify, the equipment generally needs to meet ENERGY STAR Most Efficient criteria, which typically means 16+ SEER2 and 9+ HSPF2 for heat pumps. That tax credit can significantly close the gap between a budget system and a premium one. We also offer financing options to help with the upfront cost.

How to Compare Systems Without Getting Overwhelmed

When you're looking at new equipment, focus on three things: SEER2 rating (cooling efficiency), HSPF2 rating (heating efficiency, for heat pumps), and the system's compatibility with your home's ductwork and electrical setup. Everything else, brand names, feature lists, marketing language, is secondary.

At Coastal Air Plus, we walk you through the options in plain terms so you can make a decision that fits your home and your budget. We carry Trane and Mitsubishi systems across a range of efficiency levels, and we'll help you figure out which rating gives you the best return for your situation. We make working with an HVAC contractor easy.

Why Does My House Smell Musty? A Coastal Homeowner's Guide to Indoor Odors

Fri, 20 Mar 2026 09:00:28 GMT

You walk into your house after being out for a few hours and something smells... off. Damp. Earthy. Stale. If you live near the coast in South Carolina, that musty smell is more common than you might think, and it's almost always connected to moisture that isn't being properly managed.

Here's where that smell comes from, what it means for your home and your health, and how to get rid of it for good.

The Usual Suspects Behind a Musty Smell

Excess Indoor Humidity

This is the number one cause for coastal homeowners. The Grand Strand and Lowcountry regularly see outdoor humidity levels above 80%, and that moisture works its way into your home through every crack, gap, and open door. When indoor humidity stays above 60% for extended periods, mold and mildew start growing on surfaces you can't always see: behind walls, under carpets, inside closets, and in your HVAC system. The EPA ranks indoor air quality among the top five environmental risks to public health.

Your air conditioner removes some humidity as it cools, but in a coastal climate, AC alone often isn't enough to keep indoor humidity at the ideal 40 to 60% range. That's where whole-house dehumidifiers come in.

Mold or Mildew in Your Ductwork

Your ductwork carries conditioned air to every room in your house. If moisture gets into the ducts, through leaks, condensation, or high humidity, mold can colonize inside the duct walls. Every time your system runs, it pushes air over that mold and distributes it throughout your home. If the musty smell gets stronger when your AC or heat kicks on, your ducts are the likely source. Professional duct cleaning can identify and remove mold growth.

A Clogged Condensate Drain

Your air conditioner produces water as a byproduct of cooling. That water is supposed to drain through a condensate line and exit your home. When that line clogs with algae, slime, or debris, water backs up into the drain pan and sits there. Stagnant water in a warm, dark space is a recipe for mold and that musty smell you're noticing. Regular AC maintenance includes clearing the condensate line.

Dirty or Wet Air Filters

A filter that's overdue for replacement traps moisture along with dust and debris. In a humid climate, that damp filter becomes a breeding ground for mold and bacteria, sending odors into your living space every time the blower runs.

Standing Water Under or Around Your Home

If your home has a crawl space, check for standing water, damp insulation, or visible mold underneath. Many coastal homes sit on raised foundations, and poor drainage or inadequate vapor barriers allow ground moisture to rise and permeate your flooring and ductwork.

How to Get Rid of the Musty Smell

Check and replace your air filter. This takes two minutes and might solve the problem immediately. Shop filters here .
Run a dehumidifier. A portable unit helps for a single room. For whole-home humidity control, a dehumidifier integrated with your HVAC system is the better long-term solution.
Have your condensate drain cleared. A quick maintenance visit can flush the line and prevent water backup.
Schedule a duct inspection. If the smell comes from your vents, professional duct cleaning and inspection can identify and remove mold growth inside your ductwork.
Check your crawl space. If you have standing water or visible mold under your home, address the drainage issue first, then treat the affected area.
Improve ventilation. Use exhaust fans in bathrooms and kitchens. Make sure your dryer vents outside, not into your attic or crawl space.

When to Call a Professional

If you've changed the filter, checked the obvious sources, and the smell persists, it's time to bring in a professional. Mold hidden inside walls, ductwork, or HVAC components needs proper identification and treatment, not just an air freshener.

At Coastal Air Plus, we deal with humidity and indoor air quality challenges every day across Murrells Inlet , Pawleys Island , Georgetown , and the entire coastal corridor. Our team can inspect your system, test your indoor humidity levels, clean your ductwork, and recommend the right dehumidification solution for your home.

Heat Pump vs. Furnace: Which Makes More Sense for South Carolina Homes?

Tue, 17 Mar 2026 09:30:00 GMT

If you're shopping for a new heating system, or your current one just gave up, you've probably run into this question: Should I go with a heat pump or a furnace?

It's a good question, and the answer depends on where you live, how your home is built, and what matters most to you.

Here in South Carolina, the answer leans heavily in one direction, but it's not as simple as 'always pick X.' Here's a clear breakdown so you can make the right call for your home and your budget.

How They Work (Without the Technical Jargon)

A heat pump moves heat from one place to another. In winter, it pulls heat from the outdoor air and moves it inside. In summer, it reverses and pulls heat out of your home, working exactly like an air conditioner. One system, year-round comfort. The U.S. Department of Energy has a solid overview of how heat pump systems work if you want the technical details.

A furnace burns fuel (natural gas, propane, or oil) or uses electric resistance coils to generate heat. It only heats. You still need a separate air conditioner for cooling.

The South Carolina Climate Factor

Heat pumps work most efficiently when outdoor temperatures stay above 30 to 35 degrees. Below that, they have to work harder and may need backup heating (usually electric resistance strips) to keep up. In places like Minnesota or upstate New York, that's a real concern.

In the Myrtle Beach, Conway, and Charleston areas? Temperatures below freezing are uncommon, and extended cold snaps below 30 degrees are rare. Our winters are mild enough that a heat pump can handle the vast majority of heating days without breaking a sweat. That makes heat pumps an especially strong fit for coastal South Carolina.

Cost Comparison

Upfront Cost

A heat pump system typically costs slightly more upfront than a furnace paired with an air conditioner. However, federal tax credits under the Inflation Reduction Act can offset a significant portion of that difference. Depending on the system, homeowners may qualify for up to $2,000 in federal income tax credits on a qualifying heat pump installation. We also offer flexible financing to help manage the upfront cost.

Monthly Operating Cost

Because heat pumps move heat rather than generate it, they use less energy than furnaces in mild climates. In South Carolina, most homeowners who switch from a gas furnace to a heat pump see lower combined heating and cooling costs. Electric heat pumps can deliver up to three times more heating energy than the electricity they consume.

Maintenance Cost

Heat pumps require maintenance twice a year (spring and fall) because they work year-round. Furnaces need a fall tune-up, and your separate AC needs a spring tune-up. Maintenance costs are roughly similar either way.

When a Furnace Still Makes Sense

Furnaces aren't obsolete. There are situations where a gas furnace makes sense, even in South Carolina:

Your home already has a natural gas connection and existing ductwork sized for a furnace system.

You prefer the feel of warmer air from the vents. Furnaces produce air around 120 to 140 degrees, while heat pumps produce air around 90 to 100 degrees. Both heat your home, but the air from a heat pump can feel 'less warm' coming out of the vents even though it's still raising the room temperature.

You have an older home with limited electrical capacity that would require a panel upgrade to support a heat pump.

When a Heat Pump Is the Clear Winner

For most homes in the Grand Strand and Lowcountry, a heat pump checks every box:

One system for heating and cooling, which means one unit to maintain and one set of equipment to replace.
Lower operating costs in South Carolina's mild climate.
Eligible for federal tax credits that reduce the upfront cost.
No combustion, which means no carbon monoxide risk and no gas line needed.
Works efficiently with South Carolina's temperature range 95% of the year.

Which One Is Right for Your Home?

Every home is different. The size of your house, your insulation, your existing ductwork, and your electrical panel all play a role. The best way to figure out what makes sense is to have a professional evaluate your setup and walk you through the options.

At Coastal Air Plus, we install both heat pumps and furnaces . We'll give you honest advice based on what your home actually needs, not what costs us the least or earns us the most. You won't be oversold. Our team has been helping homeowners across Conway, Myrtle Beach, Charleston, and beyond since 1947.

How Salt Air Damages Your AC Unit (and How Coastal Homeowners Can Fight Back)

Fri, 13 Mar 2026 10:00:27 GMT

Living near the beach in South Carolina comes with a lot of perks.

Ocean breezes, stunning sunsets, and year-round mild weather make coastal living hard to beat. But that same salty ocean air that makes everything feel refreshing? It's quietly destroying your outdoor AC unit.

If you live in Folly Beach , Isle of Palms , Sullivans Island , Surfside Beach , or anywhere within a few miles of the coast, your HVAC system faces challenges that inland homeowners don't deal with. Understanding what salt air does to your equipment and how to fight back can save you thousands in premature replacements.

What Salt Air Actually Does to Your System

Your outdoor condenser unit is made mostly of metal: copper tubing, aluminum fins, steel cabinets, and various fasteners. Salt particles carried by ocean breezes settle on these surfaces. When combined with South Carolina's relentless humidity, salt creates an acidic film that accelerates corrosion far beyond normal wear.

Here's what happens over time:

Condenser coil fins corrode and crumble. The thin aluminum fins on your condenser coil are the most vulnerable. As they corrode, airflow through the coil decreases. Your compressor works harder, runs hotter, and burns out sooner.
Copper refrigerant lines develop pinholes. Salt-induced corrosion can eat through copper tubing, causing slow refrigerant leaks that are expensive to locate and repair.
Electrical connections degrade. Corroded wiring terminals and contactors lead to intermittent failures, short cycling, and eventually complete system failure.
Cabinet panels rust through. The steel housing of your outdoor unit rusts from the outside in. Once the cabinet loses structural integrity, internal components are exposed to even more moisture and salt.

Homes closer to the water experience these effects faster. A unit in downtown Charleston might last 15 years, while the same unit on Folly Beach could show serious corrosion in 5 to 7 years without proper care.

How to Protect Your HVAC System from Salt Corrosion

Choose Coastal-Rated Equipment

Not all AC units are built the same. Some manufacturers offer models with factory-applied anticorrosive coatings on the coils, sometimes called 'coastal protection' or 'salt defense' packages. When it's time for a replacement, ask specifically about units designed for coastal environments. We carry Trane and Mitsubishi systems with coastal protection options. The upfront cost is slightly higher, but the extended lifespan more than makes up for it.

Rinse Your Outdoor Unit Regularly

One of the simplest things you can do is rinse your outdoor unit with a garden hose every two to four weeks, especially during months when onshore winds are strongest. Plain water washes away salt deposits before they have a chance to cause damage. Don't use a pressure washer, as the force can bend the delicate coil fins.

Schedule Maintenance Twice a Year

Inland homeowners can usually get by with annual maintenance. If you live on or near the coast, twice-a-year service is a much smarter approach. Our VIP Maintenance Club includes spring and fall visits, giving your technician two opportunities to catch corrosion early and address it before it spreads.

During each visit, your technician will clean the coils, inspect electrical connections for corrosion, check refrigerant levels (which can indicate pinhole leaks), and assess the overall condition of the cabinet and components.

Position Your Unit Wisely

If you're installing a new system or replacing an old one, placement matters. Using your home as a buffer between the unit and the prevailing ocean wind reduces direct salt exposure. Just make sure the unit still has adequate airflow clearance on all sides. Your installer should factor in both airflow and salt exposure when choosing the location.

Keep the Area Around Your Unit Clean

Sand, debris, and vegetation that trap moisture against the unit accelerate corrosion. Keep at least two feet of clearance around your condenser and check periodically for sand buildup, especially after storms.

When It's Time to Replace a Salt-Damaged System

If your outdoor unit already shows heavy corrosion, white or green powdery deposits on the coils, or rust holes in the cabinet, patching and repairing will only get you so far. At some point, replacement becomes the more cost-effective choice.

A few signs it's time to talk about a new system:

Your repair costs over the past two years exceed 50% of a new system's price.
Refrigerant leaks keep recurring despite repairs.
The coil fins are so corroded that cleaning no longer restores airflow.
Your system is over 8 to 10 years old and sits within a mile of the ocean.

At Coastal Air Plus, we work with homeowners across the Lowcountry and Grand Strand who deal with these exact challenges. Our name isn't an accident. We understand what coastal living does to HVAC systems because we've been servicing them here since 1947. When you need a repair, a maintenance plan , or a full system replacement , give us a call at 843-238-3838.

5 Signs Your Water Heater Is About to Fail (and What to Do Next)

Tue, 10 Mar 2026 09:00:21 GMT

Nobody thinks about their water heater until the morning shower goes cold.

By then, you're already in trouble. Water heaters don't usually die without warning, though. They send signals for weeks or even months before they quit. Here are five signs that your water heater is telling you something, and what to do about each one.

1. Your Hot Water Looks Rusty or Discolored

If you turn on the hot tap and the water comes out with a reddish or brownish tint, that's usually rust forming inside your tank. The anode rod, a metal rod inside the tank designed to attract corrosion, may be spent. Once that rod is gone, the tank itself starts to corrode from the inside out.

What to do: If the discoloration only happens with hot water (not cold), the problem is likely your water heater, not your pipes. Call a plumber to inspect the anode rod. Replacing it is inexpensive and can extend the life of your tank by several years. If the tank itself is corroded, replacement is the safer bet.

2. You Hear Popping, Rumbling, or Banging Noises

As sediment builds up at the bottom of your tank, it hardens and creates a layer between the burner and the water. When the burner fires, you hear popping or rumbling as water trapped under the sediment gets superheated. The more sediment, the louder and more frequent the noise.

What to do: A professional flush can remove sediment buildup and quiet things down. If your water heater hasn't been flushed in years, the sediment may be too thick to clear, and the tank may already be damaged. Annual flushing is the easiest way to prevent this.

3. Water Is Pooling Around the Base of the Tank

A puddle around your water heater is never a good sign. It could be a leaking pressure relief valve (a relatively simple fix) or a crack in the tank itself (which means replacement). Even a small leak can cause serious water damage to your floors, walls, and anything stored nearby.

What to do: Turn off the power to the unit (breaker for electric, gas valve for gas) and the cold water supply valve at the top of the tank. Then call a plumber . Don't wait on this one. A slow leak today can become a flooded room tomorrow.

4. Your Hot Water Doesn't Last Like It Used To

If you used to get through two showers and a load of dishes without running out of hot water, but now you're going cold halfway through the second shower, your water heater is losing capacity. Sediment buildup reduces the amount of water the tank can hold and heat. In electric models, a failing lower heating element is another common culprit.

What to do: Start with a professional inspection. A flush and element replacement may solve the problem. If your tank is over 10 years old and losing capacity, it may be more cost-effective to replace it than to keep repairing it. Ask your plumber about tankless options if you want hot water that never runs out.

5. Your Water Heater Is Over 10 Years Old

Most traditional tank water heaters last 8 to 12 years. If yours is approaching or past that range, it's living on borrowed time, especially here in the Lowcountry where hard water accelerates wear on internal components. Check the serial number on the manufacturer's label. The first two digits usually indicate the year it was made. The Department of Energy has helpful guidance on water heater lifespan and efficiency.

What to do: Even if your water heater seems fine, start budgeting for a replacement now. A planned replacement on your schedule is always less stressful and less expensive than an emergency swap after a flood in your utility closet. We offer flexible financing options to help make the transition easier.

Don't Wait for the Cold Shower

Your water heater works hard every day, and it's one of those appliances most people forget about until something goes wrong. If you're noticing any of these signs, a quick inspection from a licensed plumber can tell you exactly where things stand.

At Coastal Air Plus, creating lasting relationships is what we're all about. Our plumbers serve homeowners across Charleston , Mount Pleasant , Goose Creek , and the entire Grand Strand.

When Should You Schedule Your Spring AC Tune-Up in the Grand Strand?

Tue, 03 Mar 2026 11:00:20 GMT

The short answer: March or early April. If you wait until May or June, you're competing with every other homeowner in Myrtle Beach, Conway, and Surfside Beach who just realized their AC hasn't been touched since last summer. By then, our technicians are booked out, and the heat isn't waiting for anyone.

Here in the Grand Strand, we don't get much of a buffer between cool nights and scorching afternoons. One week you're wearing a jacket, and the next you're cranking the thermostat down to 72. That's why getting your spring tune-up done while the weather is still mild is the smartest move you can make for your wallet and your comfort.

Why March and April Are the Sweet Spot

South Carolina's cooling season can start as early as late April in some years. The humidity creeps in even sooner than the heat, and your AC has to manage both temperature and moisture. A system that's been sitting idle since October needs attention before you ask it to run 10 to 14 hours a day.

Scheduling your spring tune-up in March or early April gives you three advantages:

You get your pick of appointment times. During peak season, same-week appointments can be hard to come by. In March, you can usually book within a few days and choose a time that fits your schedule.
Problems get caught early. A refrigerant leak, a worn belt, or a failing capacitor found in March is a quick fix. That same problem found in July, when your AC has been straining for weeks, can turn into a full breakdown.
Your system runs efficiently from day one. A tuned-up AC uses less energy. If your system kicks on in April already cleaned and calibrated, you'll see lower energy bills from the start of the cooling season.

What Happens During a Spring AC Tune-Up

A lot of homeowners wonder what exactly a technician does during a maintenance visit. Fair question. Here's what our NATE-certified technicians check when they come to your home:

Refrigerant levels: Low refrigerant means your AC works harder and cools less. We check the charge and inspect lines for leaks.
Electrical connections: Loose or corroded connections can cause your system to short cycle or fail entirely. We tighten and test every terminal.
Coils and fins: Your evaporator and condenser coils collect dirt over the off-season. Dirty coils reduce cooling capacity and force your compressor to work overtime.
Blower motor and fan: We check the motor, lubricate bearings, and make sure airflow is strong and consistent.
Condensate drain: A clogged drain line is one of the most common causes of AC water leaks inside your home. We clear the line and make sure water drains properly.
Thermostat calibration: If your thermostat reads 72 but your house feels like 78, something's off. We verify accuracy and recommend adjustments.
Filter check: We'll check your current filter and let you know if it needs replacing. A dirty filter is the number one cause of reduced airflow and efficiency loss. You can order replacement filters here .
Ductwork inspection: We look for visible leaks, disconnections, or damage. Leaky ducts waste energy and let humidity into your living spaces. If your ducts need attention, we offer air duct replacement and repair services .

How Often Should You Schedule Maintenance?

We recommend a professional tune-up once a year for air conditioning systems , ideally in the spring before you start relying on your AC daily. If you have a heat pump that handles both heating and cooling, we recommend twice a year: once in the spring for the cooling season and once in the fall for heating.

Between professional visits, there are a few things you can do yourself to keep your system running well: change your air filter every one to three months, keep vegetation and debris away from your outdoor unit, and make sure your supply and return vents aren't blocked by furniture or curtains.

If you want to lock in priority scheduling, discounts on repairs, and never have to remember to call, our VIP Maintenance Club takes care of the scheduling for you.

What If You Skipped Maintenance Last Year?

If your AC ran all last summer without a tune-up, don't panic, but don't ignore it either. Systems that skip maintenance are more likely to break down during the hottest weeks of the year, and those emergency calls are always more expensive than a scheduled visit.

If it's been more than a year since your last professional service, schedule your tune-up as soon as possible. Our technicians will let you know if there's anything that needs attention and give you honest advice on whether a repair or a replacement makes more sense for your situation. You won't be oversold. That's our promise.

A Quick Spring AC Checklist for Grand Strand Homeowners

Use this list to get your system ready before the heat hits:

Schedule a professional AC tune-up (March or early April)
Replace your air filter if it's been more than 90 days
Clear leaves, mulch, and debris from around your outdoor unit (keep 2 feet clear on all sides)
Test your AC by running it for 15 to 20 minutes on a mild day and checking for cool air at every vent
Check your thermostat batteries and settings
Inspect visible ductwork in your attic or crawl space for disconnections or damage
Clean your supply and return vents (remove covers and vacuum dust buildup)
Consider signing up for a maintenance plan to lock in priority scheduling and discounts

At Coastal Air Plus, creating lasting relationships is what we're all about. Rest easy knowing that our reliable heating, cooling, and plumbing professionals will make your home safe and comfortable for every season. We've been taking care of homes and businesses across Conway, Myrtle Beach, Charleston, and the Grand Strand since 1947, and we're not going anywhere.

What Does Your HVAC Technician Actually Check During a Maintenance Visit?

Sat, 28 Feb 2026 16:50:06 GMT

You schedule a maintenance visit . A technician shows up, spends an hour with your system, and hands you a report. But what exactly did they do back there? It's a fair question, especially when you're paying for a service you can't always see the results of right away.

Here's a plain-English breakdown of everything a professional HVAC technician inspects, cleans, and tests during a standard maintenance appointment.

The Outdoor Unit

Your outdoor unit (the condenser) sits outside in the elements year-round. It handles salt air, pollen, yard debris, and whatever else South Carolina weather throws at it. During a maintenance visit, your technician will:

Clean the condenser coils. Dirt and grime build up on the coils and reduce your system's ability to release heat. Cleaning them restores cooling efficiency.
Inspect the fan motor and blades. A bent blade or sluggish motor means less airflow over those coils, which means harder work for the compressor.
Check refrigerant levels. Refrigerant doesn't get 'used up' like gas in a car. If levels are low, you have a leak somewhere. Your technician will measure the charge and inspect the lines.
Examine the electrical components. Capacitors, contactors, and wiring connections get checked for wear, corrosion, or loose fittings. One bad connection can shut your whole system down.
Clear the area around the unit. They'll note if vegetation, fencing, or debris is too close and restricting airflow.

The Indoor Unit

Inside your home, the air handler or furnace does the heavy lifting of moving conditioned air through your ductwork . Here's what gets checked:

Evaporator coil inspection. The indoor coil absorbs heat from your home's air. If it's dirty or frozen, cooling performance drops fast.
Blower motor and wheel. The blower pushes air through your ducts. Your technician checks the motor speed, cleans the blower wheel, and lubricates bearings if needed.
Condensate drain line. As your AC removes humidity from the air, water collects and drains through a line. When that line clogs, water backs up and can leak into your ceiling, walls, or floor. This is one of the most common service calls we get during summer, and it's almost always preventable with regular maintenance.
Air filter. Your technician will check the condition of your filter and recommend a replacement if it's dirty. A clogged filter restricts airflow, raises energy costs, and puts stress on your blower motor. You can shop for replacement filters here .

System Controls and Safety

Thermostat accuracy. Your technician verifies that the temperature your thermostat displays matches the actual room temperature. Even a two-degree difference means your system is working harder than it needs to.
Safety controls. Every HVAC system has built-in safety switches that shut the system down if something goes wrong. These get tested to make sure they're functioning.
Carbon monoxide check (for gas systems). If you have a gas furnace, your technician checks the heat exchanger for cracks and tests for carbon monoxide . This is a safety check you don't want to skip.
System cycle test. The technician runs your system through a full heating or cooling cycle to verify everything starts, runs, and shuts off the way it should.

What You Get at the End

After the inspection, your technician should walk you through what they found. At Coastal Air Plus, our team takes photos and shows you exactly what they did and what they saw. If something needs attention, we'll give you honest recommendations and let you decide what makes sense for your budget. You won't be pressured into anything you don't need.

Regular maintenance catches small problems before they become expensive repairs and keeps your system running efficiently so you're not overpaying on energy bills. Most manufacturers also require proof of annual maintenance to honor warranty claims, so keeping up with service protects your investment. Our VIP Maintenance Club makes it easy to stay on schedule.

How Can I Make My Furnace Last Longer?

Tue, 30 Jan 2024 05:24:00 GMT

The average furnace lasts between 10 and 15 years. But did you know you can take steps to make it last longer? There is no shortcut or hack to increase your furnace’s longevity.

In reality, the key is treating your Conway system with care and respect. With just a small amount of time and energy, you can ensure your furnace will live well beyond its warranty. From our team here at Coastal Air Plus , here are four things you should do to make your furnace last longer:

1. Change Your Filter Regularly

This is one of the easiest and most beneficial things you can do for your heating system. Check the manufacturer’s guidelines to see how frequently you should replace your filter.

When filters get clogged with dust and debris, it causes all sorts of problems with your furnace. The airflow becomes restricted, causing the furnace components to wear down more quickly.

2. Schedule Maintenance

You should see one of our heating, ventilation, and air conditioning (HVAC) professionals for maintenance at least once a year. Your heating equipment might have issues you can’t yet see.

Fortunately, a trained eye can spot them. Also, our technicians will clean any excess debris or mold from your equipment. This protects your furnace, as well as your South Carolina home’s air quality.

3. Regulate Your Home’s Humidity

Protecting your furnace from excess moisture is an easy step to forget. Humid temperatures can cause your unit’s parts to rust quickly. This can lead to breakdowns. It can also lead to a cracked heat exchanger, which is expensive to replace and potentially deadly. Additionally, according to the Illinois Department of Public Health , excess humidity can cause a host of other problems in your home.

4. Limit Your Use

In automotive terms, the amount of hours your furnace spends running is comparable to a car’s mileage. If you can run your heating system less frequently, you’ll get more use out of it in the long run.

A convenient way to do this is by upgrading your thermostat to either a programmable or Wi-Fi/smart thermostat. Programmable thermostats can automatically turn down your heat during hours when no one is home. Wi-Fi thermostats allow you to adjust temperatures on your smartphone or computer/laptop when you’re home or away. You can also monitor your weekly energy usage, so you can consider ways to cut down.

How to Spot a Cracked Heat Exchanger

Mon, 15 Jan 2024 14:00:00 GMT

At Coastal Air Plus , we take the safety of our customers in South Carolina seriously. That’s why we want you to know how to spot a cracked heat exchanger.

In your gas furnace, the heat exchanger is made of metal coils designed to absorb and transfer heat. The most common cause of a cracked heat exchanger is overheating. Issues that can cause overheating include poor maintenance, a clogged air filter, combustion problems, or worn-out pressure valves.

Ruptures in the coils will emit harmful gases, such as carbon monoxide (CO), nitrous oxide, and sulfur dioxide. CO leaks cause over 20,000 emergency room trips, 4,000 long-term hospitalizations, and 400 fatalities in the United States every year, according to the Centers for Disease Control and Prevention (CDC) . If you suspect you may have a CO leak, evacuate your home and call 9-1-1 immediately.

Five Signs of Heat Exchanger Damage

Keeping up with seasonal maintenance visits will greatly reduce the risk of your Conway furnace overheating. Still, it’s a good idea to know what to look out for and what action to take. Here are five signs of heat exchanger damage:

1. Strange Smells

A cracked heat exchanger sometimes produces a putrid “chemical” smell. This is one of the more immediate giveaways. However, remember that CO produces no odor. If anyone is experiencing physical symptoms in your household and you suspect a gas leak might be responsible, seek medical attention immediately and call for help.

2. Puddles Near Your Furnace

Water or condensation coming from your furnace is a sign that it needs repair. The culprit may be something more benign, like a clogged condensate drain. However, cracked heat exchangers can also produce flooding.

3. Discoloration or Black Soot

If you see soot anywhere on your furnace, you should be concerned. The fine dark powder is a byproduct of incomplete burnt carbon. Carbon that doesn’t fully burn also produces CO. This sign could point to a cracked heat exchanger. Or, it could mean your burners aren’t correctly adjusted. Both issues could pose a serious health risk due to CO fumes.

4. Damaged Exterior of your Furnace

Old, beat-up furnaces are more prone to heat exchanger failure. A well-maintained furnace will last anywhere between 15 to 30 years. Assess the condition of your furnace, check manufacturer recommendations and be sure to schedule a replacement if it has expired.

5. Health Symptoms

As previously mentioned, if you believe there is a gas leak, evacuate immediately and call 9-1-1. Early CO exposure symptoms include headaches, nausea, dizziness, and chest pains. More severe symptoms include vomiting, delirium, and fainting. Children and the elderly tend to be more sensitive.

Maintain Your Furnace

Preventative maintenance always plays a vital part with your heating, ventilation, and air conditioning (HVAC) system. Ask about our company maintenance plans that save money and keep your equipment running efficiently.

Your HVAC air filter helps maintain your indoor air quality (IAQ). Be sure to change the filter every 90 days—more so if you have pets or someone who smokes inside your home.

Is My Furnace Overheating?

Thu, 28 Dec 2023 14:00:00 GMT

Just about any electrical appliance has the potential to overheat. Furnaces are no exception. As a homeowner, you need to take precautions to lower the risk of an overheated unit. You should also be wary of the associated symptoms, so you know when to take action. Remember, if your system gets too hot, you should keep a cool head and get your furnace taken care of right away.

We want to keep our customers in the know about overheating furnaces. Our team here at Coastal Air Plus in Myrtle Beach compiled the following information for you.

How Do I Prevent My Furnace From Overheating?

The main way to keep your furnace from overheating is ensuring correct airflow. Hindered airflow causes the system’s components to work abnormally hard, causing them to overheat. Here’s how to keep your appliance in check:

Get a correctly sized filter.
Not every filter is created equal. Some filters create a resistance your system isn’t designed to handle. Be sure to read the manufacturer’s recommendations on correct filters, and consult a heating, ventilation, and air conditioning (HVAC) expert if you’re still not sure.
Change/clean your filter routinely.
If you let the dust settle for too long, your filter can become clogged. This clog significantly compromises airflow, which causes the machine’s parts to overwork and eventually fail. Check the manufacturer’s manual to see how frequently you need to change your filter. We, as well as ENERGY STAR®, typically recommend at least every three months .
Be sure your vents/ducts aren’t blocked.
Blockages in your vents are hard on your furnace, causing the equipment to run for too long. Be sure to clear away any obstructions near and/or on them, including carpets, furniture, and curtains. Additionally, keep your ducts clean and free of any leaks or constrictions.
Have a technician perform routine maintenance.
Regular maintenance , annually or semiannually, is a necessary step in protecting the condition of your system. One of our Coastal Air Plus technicians will clean any dirty coils, fasten loose components, and be sure the system is performing optimally. This will significantly lower the risk of a malfunction.

How Do I Know My Furnace Is Overheating?

When your furnace overheats , it loses some or all of its functionality. Therefore, it probably won’t go unnoticed. Here are some giveaway signs:

Your furnace shuts down before completing a cycle.
This is the most common sign of overheating. It actually shuts down to protect you. When your heat exchanger gets to an unsafe temperature, the high-limit switch detects this and automatically turns the furnace off.
You smell a burning odor.
If you’ve just turned on your South Carolina furnace for the first time in a while, you can expect a slight burning smell for about 20 to 30 minutes. However, a constant burning smell is a serious cause for concern. Call one of our professional technicians immediately.
You notice an unusual humming sound.
A loud humming noise likely means your motor is overworked and about to give out. In this case, you should immediately turn your furnace off (if it doesn’t turn off on its own first). Then call one of our experts immediately.

How Does My Gas Furnace Work?

Fri, 15 Dec 2023 14:00:00 GMT

On a frosty winter’s day here in South Carolina, your gas furnace is hard at work, keeping your Conway home warm and cozy. Feeling grateful? You’re not alone—it’s one of the most popular forms of heating, as American as apple pie.

In 1919, New Jersey inventor Alice H. Parker filed a patent for the first gas-fueled furnace. Years later, the basic technology is the same—only it burns less gas. In fact, modern furnaces burn at up to 97 percent efficiency , according to Consumer Reports. Keep this in mind if you’ve owned your heater for 10 years or longer.

Our team at Coastal Air Plus could help you save big bucks on your monthly utility bill by performing a furnace replacement. And while we’re on the topic, we can help with your other HVAC needs: air conditioning, heat pumps, indoor air quality (IAQ), and more. All you need to do is call.

How a Gas Furnace Works

Furnaces that burn natural gas have four basic elements:

1. The Thermostat

Your thermostat is the eyes and ears of the operation. If it senses your home is below the target temperature, it sends signals to your furnace. Then, your furnace continues to cycle until your home is adequately warm. Finally, when it detects the desired temperature, the thermostat tells your furnace to stop running (until further notice).

2. The Ignitor

When your thermostat sends out a signal, the ignitor is the first to respond. Like the ignition starts your car—the ignitor starts your furnace.

If your heater is a decade old (or older), the ignitor might be a pilot light. The pilot stays lit 24/7, running on a small stream of natural gas. Newer furnaces have an electric ignitor, a considerably safer option. Electric ignitors are less risky because if your pilot goes out, you will quickly have a house full of gas fumes.

3. The Combustion Chamber

Next on the chain is the combustion chamber. This is where the ignitor lights the fuel. The natural gas becomes intertwined with oxygen supplied via a vent system or draft hood. The oxygen ensures that the fuel burns both cleanly and efficiently.

Besides taking in oxygen, the ventilation system pushes out exhaust through your flue. Economy flues are usually made out of galvanized steel. However, homeowners with polypropylene venting see long-term savings due to higher efficiency. The latter is also quite easy to install.

Whatever your flue is made out of—stay on top of maintenance. A clean flue ensures healthy air and prevents gas from getting squandered.

4. The Heat Exchanger

The combustion chamber emits heat, which gets collected by the heat exchanger. From there, the heat exchanger collects and distributes the treated air to your ductwork using burner-heated metal tubes.

When the tubes reach the right temperature, the furnace motor kicks on and begins blowing the air throughout your Conway home with the help of fans.

High-efficiency furnaces have variable-speed blowers, which use less energy and allow tighter temperature control. These premium models may also have multiple heat exchangers, which helps your furnace use less fuel.

Remember to schedule seasonal maintenance—a cracked heat exchanger can lead to a dangerous carbon monoxide (CO) leak.

How to Determine Heat Pump Efficiency

Wed, 29 Nov 2023 14:00:00 GMT

If you are in the market for a new heat pump , efficiency is probably a key factor in your search. The Air Conditioning, Heating, and Refrigeration Institute (AHRI) has a universal ranking system for heating and cooling units that serves to help.

Deciphering and Decoding

You might have seen assorted abbreviations like HSPF or SEER, but what do they actually mean? Well, here is a guide to determining heat pump efficiency.

What Is HSPF?

HSPF stands for Heating Seasonal Performance Factor. This rating represents the amount of heat units produced (BTUs––British Thermal Units) by the total amount of electricity (watt-hours) used over the course of a season. Generally speaking, the higher a heat pump’s HSPF, the more efficient it is.

The US ENERGY STAR ® program has set a minimum HSPF of 8 for single-package equipment, which is a traditional heating and cooling unit. For mini split configurations, also known as ductless systems, the minimum HSPF is 8.2.

What Is SEER?

SEER stands for Seasonal Energy Efficiency Rating . It is essentially the equivalent of HSPF but for cooling. A system’s SEER rating is determined by the amount of cooling power (BTUs) divided by the amount of energy (watt-hours) used within one season.

A higher SEER means a more efficient heat pump. The minimum ENERGY STAR-qualifying SEER is 14 for single-package equipment and 14.5 for mini split systems.

Which Heat Pump Should I Get?

Generally speaking, if you live in a cooler climate, HSPF should have more weight in your decision than SEER, since you will likely be running the system on this setting more frequently. You should favor SEER for the same reason in hotter climates.

However, it is important to note both of these rating systems refer to a heat pump operating under optimal conditions. If a heat pump is not the right size for your Myrtle Beach home, you can run into all sorts of problems.

An oversized unit may short cycle, potentially increasing your energy bill a very significant amount. An undersized unit will run for too long, which means its components may be overworked, and it may use more electricity than expected.

The best way to get the most efficient heat pump is to schedule an in-home consultation with one of our Coastal Air Plus professionals . We will perform the necessary heat-load calculations to determine which heat pumps will perform ideally in your South Carolina space. Out of these options, you can choose the best one to meet your efficiency standards.

5 Things You Should Know About Geothermal Maintenance

Wed, 15 Nov 2023 14:00:00 GMT

One of the benefits of having a geothermal system for your Conway home is the minimal maintenance it requires.

Unlike a traditional furnace or air conditioning system that requires regular and sometimes monthly maintenance, a geothermal heat pump system is much more efficient and does not require the same frequency of attention. According to the US Department of Energy (DOE), there are approximately 50,000 geothermal heat pumps installed in the United States each year .

At Coastal Air Plus, our heating, ventilation, and air conditioning (HVAC) professionals regularly maintain geothermal heat pumps and witness firsthand the benefits of regularly maintaining your system. Maintenance is so crucial to the efficiency and long life of your system , you should know the five things below about geothermal maintenance.

1. Installation

Be sure you have a properly and professionally installed geothermal system. Our experts at Coastal Air Plus are certified and trained to install your geothermal system correctly in your South Carolina home. The interior systems of a geothermal heat pump are the same as a standard heat pump, but the outdoor components require careful planning for installation. Each setup is unique based on the geography of your yard.

2. Antifreeze

The loops in your geothermal system are filled with antifreeze or a water/antifreeze mix. You need to maintain a proper level in order for your system to work properly. Your system will require a routine professional inspection of the levels of antifreeze in the loop. During your maintenance check, one of our experts can also inspect the pressure and temperature within the loop.

3. Dirt/Debris

Since your geothermal system is outside as well as inside, there is the possibility that dirt or other matter can damage it. We will clean all parts of your system that may be influenced by debris, such as the heat exchange or blower. These parts are very sensitive, and we do not recommend you attempt to clean them yourself.

4. Air Ducts

Your air ducts are just as important to your geothermal system as they are to a traditional furnace or air conditioning setup. To keep your airflow efficient and consistent, you must take care to maintain the health of your ducts. Keep them clean, regularly inspect them for leaks, and repair them when and as needed.

5. Piping

Be sure one of our heating and cooling professionals inspects the pipes in your loop during your scheduled maintenance. Pipe health is crucial to the functionality of your geothermal system. Damaged piping can lead to a number of other issues that may occur with your geothermal system. It is critical to be sure they remain in good repair.

7 Furnace Maintenance Tips

Tue, 31 Oct 2023 13:00:00 GMT

It’s understandable that maintenance tasks often fall by the wayside. Many Myrtle Beach homeowners follow the mantra of “if it ain’t broke, don’t fix it.” Everyone is busy and many seemingly more important priorities tend to creep up every month to consume time and money.

However, the last thing you want to worry about when the weather takes a turn toward winter is a broken furnace. Our team at Coastal Air Plus wants to help you be prepared by providing the following furnace maintenance tips.

1. Change Your Filter Regularly

This is probably the easiest and one of the most important regular maintenance items a South Carolina homeowner can perform. Clean filters allow air to circulate through your furnace efficiently and prolong the life of your system. Be sure to check the furnace and filter manufacturers’ recommendations on the frequency of filter changes.

This will also help improve your overall indoor air quality in your home. And, according to the U.S. Department of Energy (DOE), furnace filter changes can reduce your energy bill by 5 to 15 percent as well.

2. Understand Your System and Recommended Maintenance

Although most furnaces in the United States are natural gas or electric, many other heating systems such as propane, geothermal, heat pump, and radiant floor heating are now available.

Understand what kind of system provides your home with its heat, and learn how that particular system needs to be maintained. Some systems, such as radiant floor heating, may not require any maintenance while more common systems like natural gas heating need regular inspections and tune-ups to operate efficiently and dependably.

3. Think Safety First

If you decide to perform any other maintenance tasks beyond basic filter changes, be sure you put safety first. Turn off the power to your furnace before you begin to take things apart to protect yourself from getting injured. Consider hiring a professional to help with any inspection, cleaning, tune-ups, or repairs that are more complicated or you are uncomfortable trying yourself.

4. Use Your Senses

It’s easy to pass by your furnace every day and not notice it. Take the time to look at your overall system, especially in the fall, to see if you notice anything obviously amiss.

First, if you detect the odor of rotten eggs, call your utility company immediately. That can signify a gas leak, which can be extremely dangerous in your home.

Second, be sure the venting pipe is sitting at the correct angle and is secure. You should check to be sure all tubes are fastened as well. Listen for any unusual sounds or anything else out of the ordinary .

5. Clean Drainage Tube

If you are running a natural gas or propane furnace, it will create some water as a by-product. Although some moisture becomes steam, you’ll also have some water drain out into a drip pan.

Be sure this drainage tube remains clean and clear. Backed up water can damage your flame sensor. You can use compressed air to clear the tube as well white vinegar to reduce any residual.

6. Get Tidy

Dirt and dust can hamper the performance of your furnace , so regular cleaning should be part of your annual maintenance. Although you can clean around your unit easily, be careful if you try to clean the inside of your furnace.

Some components are very sensitive and can become damaged if you don’t know what you are doing. You can use a soft brush to gently loosen dust before vacuuming or contact one of our Coastal Air Plus professionals to do the job.

7. Perform More Thorough Inspections

If you are mechanically inclined, you can continue checking things like your burner flames to be sure they are even and blue. You can check your thermostat wires to be sure they are securely connected. Clean the flame sensor so it can continue to do its job well. This can be done with an emery cloth.

Contact Us for Your Furnace Needs

Even if you can handle many of these maintenance items yourself, it’s a good idea to have one of our trained and experienced professionals come annually and do a thorough inspection and cleaning. It keeps your system’s manufacturer’s warranty intact, as most specify professional maintenance must be performed annually.

Ductless Mini Splits for Comfortable and Healthy Living

Fri, 13 Oct 2023 15:00:00 GMT

Your home is a place for rest and relaxation. Heating and cooling is a big part of that equation—but so is indoor air quality (IAQ).

Modern homes are well-insulated—which is excellent for temperature control but not ideal for air quality. Your home can trap molecules that trigger allergies or other respiratory issues. That’s why adequate ventilation and balanced humidity are so important.

Fortunately, ductless mini splits can provide all the essentials for home comfort—warm air, cool air, ventilation, and humidity control. Plus, they’re much more efficient than a standard air conditioner and furnace combination.

According to ENERGY STAR ®, you’ll save on average 30 percent on cooling and 60 percent on heating by switching to ductless.

Homeowners in Europe and Asia have known about ductless mini splits for decades. But in recent years, an increasing number of South Carolina families have adopted the same technology.

Coastal Air Plus is pleased to supply and install a wide variety of heating, ventilation, and air conditioning (HVAC) options for our customers in Conway and beyond. If you’re considering ductless units for your home, consult with one of our South Carolina experts. We’re ready to collaborate on a solution that takes your home comfort to the next level.

How Ductless Units Work Their Magic

Ductless units have an indoor module (the air handler) and an outdoor module (the compressor/condenser).

The outdoor module is a miniature box fan. On a warm day, it expels heat and humidity extracted from your home to produce cool air. On a cool day, it extracts heat from the air and sends it into your home.

The indoor module is small and rectangular, resembling an ultramodern light fixture. It mounts to the wall or ceiling and disperses air into the room through vents.

Why They’re Wonderful

Remodeling projects are fun, but what happens when you are trying to remodel a room without ductwork—such as your attic, basement, or garage? A ductless mini split provides you with a flexible solution.

Older majestic homes without ductwork can also take advantage of these systems. Other benefits include:

Room-Specific Climate Control

Because mini splits don’t use air ducts, you may need to install multiple units to provide comfort throughout your entire Conway home. In many ways, this can be beneficial. It allows you to have individual control over temperature settings on different floors or rooms in your Conway home. You can also cut down your energy use by only heating or cooling rooms as they’re being used.

Enhanced Air Quality

Ductless units are essential for families with allergies or asthma. They contain large air filters that catch harmful molecules like dust, dander, and pollen. Some high-end models can filter out up to 99.9 percent of airborne bacteria. On top of that, they remove humidity from the air and provide ventilation, making it harder for mildew and mold to grow.

Low Noise Pollution

Standard heating and cooling equipment emit a dull hiss or roar as it cycles. You may find this distracting when you’re trying to focus on work or fall asleep. In stark contrast, ductless blowers are whisper-silent. That’s one more way they make your home a peaceful and relaxing place.

High Efficiency

These all-in-one heating and cooling units will reduce your energy usage drastically. Homeowners in areas where the temperature dips below freezing may consider supplementing their ductless system with a furnace or boiler. But even then, it’s possible to realize massive savings.

Air Conditioners: Things You May Not Have Known

Fri, 29 Sep 2023 13:00:00 GMT

Though air conditioners are a major part of modern life, they hold many secrets few people know about.

Luckily, our team at Coastal Air Plus is ready to spill the beans.

Air conditioners have come a long way since they were first invented. Present-day AC units use 30 to 50 percent less electricity to create the same amount of cooling as their 1970s predecessors , according to the US Department of Energy (DOE). Advances in the past 10 years have been significant. In fact, by switching out your decade-old AC, you could subtract 20 to 40 percent from your utility bill.

But wait—we’ve compiled even more fun facts! If Jeopardy! ever makes “Cooling” a category, and you’re a contestant, we want to help you answer with confidence. You’ll make your friends back in South Carolina proud.

Read further to learn six staggering secrets about air conditioners.

Your AC Does Not Create Cool Air

AC units pull heat and humidity out of the air, flushing it out through the outdoor condenser and condensate drain. Your AC cools down your Myrtle Beach home by subtracting hot air—it doesn’t actually add anything .

Who Invented the Air Conditioner?

In 1902, New York engineer Willis Carrier drew up plans for a humidity control device. For years, Carrier was pining for a way to control indoor climate. Then, one day on a foggy train ride through Pittsburg, an idea came to him: he could subtract humidity from air by moving it through water to make fog.

We Need Our AC for More Than Just Home Comfort

Refrigerators, computers, modern shopping centers, and countless other everyday luxuries would not be possible without Carrier’s invention. The ability to control indoor climate changed the game, paving the way for generations to come.

Your AC Is Great for Indoor Air Quality

Less humidity means less mold and mildew, which can trigger respiratory symptoms for allergic residents. Your central air system also contains a static air filter, which catches irritants like dust, debris, pollen, and dander. Because of these features, running your AC can improve indoor air quality (IAQ) .

You Need to Change Your Air Filter!

Remember to change your filter every 90 days or so—or clean it once a month if you have a ductless system. Over time, dust particles clump and begin to stifle airflow . This can make your equipment overwork itself, leading to higher utility bills and even damage overtime. A bit of diligence goes a long way.

Seasonal Maintenance Is a Must

Give your AC some TLC. With the hustle and bustle of summertime, many homeowners forget to schedule their seasonal maintenance visits . During a maintenance call, one of our heating, ventilation, and air conditioning (HVAC) specialists can identify hidden issues and correct them before they turn into costly repairs. You’ll greatly reduce the risk of a breakdown on a sweltering summer’s day.

How to Reduce Dust in Your Home

Tue, 19 Sep 2023 13:00:00 GMT

Don’t let your home be another one that bites the dust.

Everyone has it, and nobody wants it. In reality, dust is no laughing matter, no matter the setting. It’s easy to see how it can affect the indoor air quality (IAQ) of your Conway home.

At Coastal Air Plus, we know how important clean indoor air quality is for your home. Our team specializes in offering whole-house solutions to keep you and your loved ones healthy, comfortable, and safe throughout the year.

Regular Maintenance Will Help

With indoor air quality typically being dirtier than your outdoor air, you need to take measures to reduce factors contributing to indoor pollution––both for your health and the health of your home.

Keep in mind, completely eliminating or eradicating dust from your home is an impossible task. Because it is virtually everywhere in South Carolina, you can understand why it will always exist in your home. However, you can greatly reduce household dust levels by following some of the recommendations below.

Take Good Care of Your Air Filter

The purpose of the air filter for your heating, ventilation, and air conditioning (HVAC) setup is to trap dust and debris flowing through the unit’s air. The air in your home is vented through your HVAC system and forced through its filter. Using the best filter you can afford (and recommended by your system’s manufacturer) can trap a lot of the dust traveling through the air.

Pay attention to your filter’s Minimum Efficiency Reporting Value (MERV), a measurement scale created by the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) to rate the effectiveness of air filters. Be sure to purchase filters with the appropriate MERV rating for your HVAC system.

You also want to change your filter on a regular basis, depending on how dirty it becomes. Optimally, we recommend changing it every month but at least every two to three months, especially if you or someone in your home suffers from allergies, asthma, or chronic respiratory conditions.

A good rule of thumb is to check your filter monthly. If it’s dirty, change it. When your filter is clogged, besides hurting your HVAC system, it obviously can’t do its job of reducing the dust in your home.

Be Sure to Check Your Air Ducts

If you have a forced-air HVAC system, you have air ducts carrying your home’s air to and from your heating and cooling system. If your ducts are not sealed well or have leaks, unfiltered air will be sneaking out into your home. You could have as much as 30 percent leakage due to this poor sealing and leaks, meaning this air has not yet made it to your filter and will be spreading dust throughout your home.

It can be worse if your air ducts are filthy. The air passing through the ducts will pick up additional dust and dirt, depositing them throughout your home.

If you notice a continuously high level of dust in your home, call in one of our indoor air quality professionals to check the seals on your ducts and to inspect for leaks. Also, seriously consider getting your ducts cleaned, especially if you have never done so in the past.

Clean Your Home Regularly

In addition to the numerous HVAC steps you can take to reduce dust, there are some things you can do while cleaning your house to help:

Eliminate clutter as it collects dust.
Vacuum one to two times a week, using a vacuum with a high-efficiency particulate air (HEPA) filter if possible.
Dust with a microfiber or damp cloth, starting the cleaning motion from top to bottom.
Wash bedding routinely––sheets and pillowcases once a week; blankets, duvets, and pillows every three to four weeks.
Avoid wall-to-wall carpeting because it can be an ideal habitat for dust and dust mites.

Keep a Constant Tab on Your Humidity

Be sure your home has the appropriate level of humidity. Too high, it encourages dust mites. Too low, dust accumulates more. Try to maintain a relative humidity of 35 to 50 percent, an industry standard.

Get Yourself an Air Purifier

A whole-home air purifier works with your HVAC system to purify the air, ridding it of dust and other particles and allergens––the dust never makes it to your home’s living spaces.

A major benefit of a whole-home purifier is how it purifies all the air in your home at once. Portable units typically can only purify the air in one room. You would need a separate purifier in every room to achieve a similar result.

Air Conditioning Noise Concerns

Thu, 31 Aug 2023 13:00:00 GMT

Very few central air conditioners (AC) are whisper-silent. A certain amount of noise coming from your ductwork is not uncommon. It is normal to hear the blowers spinning, among other parts of the cooling process.

Additionally, air conditioning equipment produces more sounds as it ages—not always because of a mechanical problem. However, if you’ve owned your unit for a decade or longer, it might be time for a replacement.

Fortunately, air conditioning units have become much more efficient in recent years. You can cut energy costs up to 40 percent by upgrading your unit if it is 10 years or older, according to the U.S. Department of Energy (DOE) .

Have a Coastal Air Plus expert evaluate your air conditioner today—we’re always happy to help our South Carolina customers save money and get the most value from your heating, ventilation, and air conditioning (HVAC) system.

Plus, our financing plans help you purchase the HVAC equipment your family deserves! Now, let’s learn about AC noises.

Air Conditioning Noises and What They Mean

While some noise is normal, keep an ear out for unusual sounds. Remember, it’s best to catch problems early. If you think your Myrtle Beach air conditioning unit needs repair, give us a call right away.

Here are some common noises and what they could mean for your air conditioner:

Popping
Popping means there may be an issue with your ventilation system. It usually points to an airflow obstruction inside your ductwork. Like many HVAC mishaps, you can help avoid this issue with seasonal maintenance.

Rattling
Rattling likely means a part in your AC has come loose. On some occasions, it’s a harmless problem. For instance, a stray nut or bolt may have fallen off your equipment. Or, it might mean a small object fell into a floor vent. On other occasions, it could point to a more serious issue—such as a loose compressor, which is costly to replace. If you hear rattling, it’s always the safest bet to call your HVAC specialist.

Grinding
If you hear the sound of metal grinding together, this could indicate a problem. The noise could be coming from a failing fan motor. Alternately, it may mean a bearing has become worn. Either way, have an HVAC specialist look at it as soon as possible.

Hissing
Hissing coming from your ducts may mean you’re experiencing a refrigerant leak. You may also notice an odd chemical smell. This problem needs to be addressed by a professional right away.

Maintenance Matters

Preventative maintenance plays a vital role in the efficiency of all your HVAC equipment. Schedule your air conditioning tune-up in the early spring and a furnace tune-up in the fall. That way, you prepare your system for the season. Plus, you give our techs a chance to uncover a minor issue before it turns into a costly repair. Call us today to schedule a tune-up.

And be sure to ask about our maintenance agreements tailored to save you money on parts, labor, and repairs!

Planning to Remodel? Go Ductless!

Fri, 18 Aug 2023 13:00:00 GMT

You probably already know about the advantages of ductless heating and cooling systems—and how they can significantly lower your Conway home’s carbon footprint while improving your indoor air quality (IAQ) .

But did you know that going ductless is the perfect solution for many remodeling projects?

A ductless system , also known as a mini split, can add comfort to areas of your South Carolina home where ductwork cannot reach. Whether you are remodeling or adding new living space, our team at Coastal Air Plus is ready to assist.

Remodeling and Ductless Mini Splits

You want to convert an unused room into a workout space or a guest room. It could be the attic, the basement, or even the attached garage. You have plenty of space, but you will need to extend your ductwork for heating and cooling.

A mini split avoids that problem. You can supplement your central HVAC system by adding a ductless system to a specific area of your home. No tearing out walls to add air ducts. A ductless system is much easier to install.

Additional new living space in your home means more work for your HVAC equipment. Adding a ductless system can supplement your furnace and AC, giving you the coverage your home needs.

Add More Comfort to Your Older Home

Are you purchasing an older home? Many of our charming historic homes here in South Carolina, do not have ductwork. A ductless mini split offers the perfect solution.

Doing so provides more than comfort—it can save you money: ENERGY STAR ® estimates ductless mini splits use 60 percent less energy to heat and 30 percent less energy to cool than central HVAC systems .

You can trust our team at Coastal Air Plus to recommend the best ductless solution for your home or business. We’ve been serving customers in South Carolina with quality products from leading manufacturers.

How Does a Ductless Mini Split Work?

A mini split has two major components: an outdoor condenser and one or more indoor mounted units. A small conduit housing the condensate drain, suction tubing, refrigerant tubing, and power cable connects the two units.

You control the temperature using a remote controller, or on a mobile device app when coupled with a smart thermostat. A ductless system provides you with year-round comfort.

Want to add a zone control system? Ductless allows you to add multiple air handlers throughout your home. Doing so creates zoning since each air handler has a separate thermostat.

Advantages of Going Ductless

The best advantage comes from money saving. According to the U.S. Department of Energy (DOE), nearly half of the energy costs in the average home go toward heating and cooling . A ductless system can lower those costs significantly.

Other advantages you’ll enjoy:

Less noise — these systems operate whisper quiet.
More flexibility — ductwork requires grilles or vents you cannot block with furniture. A ductless system has mounted indoor units that attach to the wall or ceiling.
Improved air quality — dust, mold, and other contaminants can infiltrate your ductwork.

Your system might even qualify for rebates and incentives!

Consider a Ductless AC System

Fri, 28 Jul 2023 13:00:00 GMT

When you think of heating, ventilation, and air conditioning (HVAC) systems, you probably think of the furnace and air conditioner (AC) equipment inside, an air conditioner component outside, and a network of ducts running throughout your Myrtle Beach home.

Although many HVAC systems are designed that way, there are other alternatives. Our team at Coastal Air Plus wants you to be well-informed about your options, and those options include ductless air conditioning systems that can function as an air conditioner only or a heat source as well.

Different Design

Unlike conventional whole-house HVAC systems, ductless systems are much more compact and can be installed most anywhere in your home. Also referred to as a ductless mini split system or a ductless heat pump, these systems have only three main components.

The indoor unit, which is typically installed on a room’s wall or ceiling, is the air handler. The outdoor unit is the condenser. Then the third component is the small conduit connecting the indoor and outdoor components through a small, three-inch hole in your wall. The conduit houses the condensate drain, suction tubing, refrigerant tubing, and power cable.

Best Applications

There is no one-size fits all in HVAC systems. Instead, every home in South Carolina will require a specific heating and cooling solution designed for that particular space.

Ductless air conditioners can work anywhere in your home. You could even set up a zones system for your entire home, with up to eight inside ductless units connected to only one outdoor component.

You might choose to install a ductless system in an area of your home that has no access to your current home ductwork or if you simply want separate temperature control there, such as a house addition, garage, attic, or basement or in an area which requires a different temperature than the rest of your home. For example, a home office used only during business hours or a recreation room that’s active only on weekends would be a perfect application for this type of heating and cooling system. In addition, a ductless system can be a great solution for a small apartment.

Advantages

One of the biggest advantages of a ductless system is you don’t lose energy while your cooled air travels through your duct system, since this system is ductless. According to the US Department of Energy (DOE), more than 30 percent of energy can be lost through air ducts .

Ductless systems also have more efficient compressors. Conventional HVAC compressors typically turn on and off to regulate temperature as determined by your home’s thermostat. Conversely, compressors in ductless systems simply slow down or speed up, saving significant energy by eliminating that on and off cycling.

Another benefit ductless systems can provide is an easy way to establish different comfort and temperature zones in your home. Bedrooms can be cooled or warmed during sleeping hours while the rest of the home is in energy-saving mode. Guest rooms can be made more comfortable when you have visitors while staying energy efficient most of the time.

In addition, ductless air conditioning systems are small and quiet . They can be very energy-efficient solutions, saving the cooling lost through an air duct system in a traditional central air conditioning system or the energy lost around a window air conditioner.

When chosen, different models can also be used for supplemental heating in the winter. In this way, it operates like a heat pump, moving heat from inside to outside in the summer and from outside to inside in the winter.

Disadvantages

Ductless air conditioning systems can be initially more expensive to purchase when compared with more conventional options. However, you will be able to recoup some of these initial costs through long-term energy savings. And the installation itself is typically less costly since the installation time for these systems is much less than a traditional HVAC system.

You should also note that filter changes and cleaning must be diligently performed in order to keep the unit operating at its best. Repairs can be more expensive if regular maintenance is ignored.

How Can You Manage Your Home’s Humidity?

Wed, 19 Jul 2023 13:00:00 GMT

Indoor humidity is a drag. It makes relaxing extremely difficult—after all, you are sweating inside your home! It can affect your health, triggering asthma attacks and flaring allergies. It tends to put everyone in a sluggish mood—even the goldfish. Let’s zap that excess moisture right out of the room, and look at ways to manage your South Carolina home’s relative indoor humidity.

At Coastal Air Plus , we always strive to find ways to improve your comfort and energy savings. We believe you should control your comfort, and it starts with your indoor air quality (IAQ) and relative indoor humidity.

How to Manage Your Home’s Humidity

First of all let us answer the main question: what humidity level do I want in my Conway home?

The answer is going to be different for every person! It’s like the temperature—some like it hot and others like it cold. Typically, you want your humidity between 30 and 50 percent for ideal comfort levels.

According to the US Environmental Protection Agency (EPA), reducing indoor humidity levels to below 60 percent helps control the growth of mold and reduces potential heath problems associated with mold exposures such as allergic reactions, asthma and other respiratory issues. A relatively inexpensive instrument called a hygrometer can measure the indoor relative humidity at your home or business.

Dehumidification

Your air conditioner (AC) removes humidity from the air, but this is not always sufficient to maintain ideal humidity levels in the home. The best recommendation for managing the excessive humidity levels in your home is to install a whole-house dehumidifier. This device works with your heating, ventilation, and air conditioning (HVAC) equipment to remove moisture from the air before it circulates through your Conway home.

A dehumidifier helps to keep your home comfortable all summer long. It operates similarly to your AC unit in that moisture is collected by a refrigeration coil within the device. This excessive moisture is then drained and the conditioned air is distributed throughout the home.

Signs that you have too much humidity at home:

Moist or sticky air
Damp or musty smell
Condensation on your windows
Wet walls
Bacterial growth (in either the home, attic, or crawlspace)

Too much humidity in the air can cause:

Poor indoor air quality that could lead to illness
Mold, mildew, and bacteria growth
Worse or more frequent symptoms for asthma or allergy sufferers
Damage to your home from extensive exposure to moisture

Humidification

There are a few different options for whole-house humidifier systems, but they all essentially add moisture to the air in your central heating system to increase humidity levels to the desired range.

A properly designed and installed humidification system can make a significant difference in a home, but only if designed and installed properly. A poorly installed system can cause a world of headaches for the unsuspecting homeowner. Improper humidification and design can lead to mold or bacterial growth throughout the home or attic. Equipment failure due to poor installation can lead to leaks and damage ceilings, wall, insulation, framing, or even roofing.

Signs that you do not have enough humidity at home:

Asthma and allergy symptoms worsen
Dry skin and chapped lips
Wooden floors or furniture which dries out and cracks
Your home never feels as warm as the thermostat indicates

A lack of humidity can cause:

Sickness to spread more easily
Home damage from dry/cracked wood
Increase in utility bills

Fix Your Ducts!

Before considering a whole-house system to add or remove humidity from your home, first ensure your home and ductwork is properly sealed and insulated. No system can keep a home comfortable if these things are not up to standard. Schedule an appointment with Coastal Air Plus to have one of our professionals inspect and seal your ductwork so we can determine the next step to maintaining ideal humidity levels in your home.

4 Factors to Consider When Buying a Heat Pump

Mon, 19 Jun 2023 13:00:00 GMT

So you are looking to invest in a heat pump. You are not alone––many Americans are making the switch.

Why? For starters, heat pumps are generally more efficient than a traditional heating, ventilation, and air conditioning (HVAC) system. What is more, they offer both heating and cooling, so they are versatile.

At Coastal Air Plus , we want to help you make wise decisions that meet your Conway home’s needs.

Why? Because we want you to be satisfied with your heat pump for years to come.

How to Choose a Heat Pump for Your South Carolina Home

Here are four questions to ask yourself when picking out a new heat pump :

1. How much do I want to spend up front?

Heat pumps offer you more efficiency. Geoth ermal and water-source heat pumps, in particular, are incredibly efficient since they use a minimal amount of electricity to transfer heat.

While many of the more efficient products have a higher initial cost than a conventional furnace or air conditioner. A good rule of thumb is the more you invest up front, the less you will pay in the long run. It is up to you to decide which heat pump is best for your budget.

2. What type of heat pump do I want?

Air-source, mini split, water-source, and geothermal are a few main types of heat pumps.

Air-source pumps transfer heat from the outdoor air to warm your South Carolina home in the winter and expel heat from your home during the summer. This type of heat pump is so efficient, the US Department of Energy (DOE) asserts an “air-source heat pump can deliver one-and-a-half to three times more heat energy to a home than the electrical energy it consumes .”

Mini splits work similarly but without ducts—which is why they are also called ductless units.

Water-source heat pumps draw heat from a pond, lake, or water deposit, while geothermal heat pumps draw from below the surface. Each type has its advantages and disadvantages.

3. Will I need a dual-fuel system?

Some heat pumps can’t operate as efficiently in temperatures below 40 degrees Fahrenheit. That is why if you live in a climate with freezing winters, you might need a dual-fuel system.

A dual-fuel system is a heat pump supplemented with a different heating appliance. When temperatures are too low for your heat pump to operate efficiently, your furnace or boiler will kick on.

Talk to one of our Coastal Air Plus HVAC professionals to determine if this is necessary in your case.

4. What type of thermostat should I buy?

In addition to your heat pump, our highly trained and experienced experts can install new heating and cooling controls. Based on your Conway home needs, you can choose between a standard, programmable, or Wi-Fi thermostat.

Wi-Fi thermostats can be controlled remotely using your smartphone or tablet. Depending on the model, your Wi-Fi thermostat may even offer energy-usage analytics so you can easily monitor your consumption.

Video – When Do I Need to Replace My Air Conditioner?

Wed, 31 May 2023 12:00:00 GMT

The central air conditioning system is a simple pleasure of everyday life. Your home should be a place where you can relax. On a hot day, cool air is essential to your relaxation. If you take good care of your air conditioner with annual inspections and monthly filter swaps, it should last 10 to 15 years.

Controlling Humidity in Your Home

Fri, 19 May 2023 12:00:00 GMT

At the height of summer, the weather can get quite sticky here in South Carolina .

Hot days feel much less bearable when accompanied by humidity. That’s because increased humidity makes it harder for your sweat to evaporate. Our staff at Coastal Air + Refrigeration reminds our neighbors to stay safe this summer. Monitor weather advisories and drink plenty of water, and pay attention to how you feel when it’s hot out.

Humidity isn’t just hard on your body—it’s hard on your Conway home. Damp surfaces are a picnic party for unwelcome guests like mildew, mold, cockroaches, and mites. Excessive humidity weakens wood and leads to rotting. It also lowers your indoor air quality (IAQ).

The U.S. Environmental Protection Agency (EPA) recommends an indoor humidity range between between 30 and 50 percent. Experts consider levels above 60 percent cause for concern.

To keep your house safe and comfortable on the balmiest of days, here are 10 tips from our team:

1. Increase and Optimize Air Ventilation

More airflow means drier surfaces and fewer chances for mold to grow. Consider switching your thermostat fan setting from Auto to On to create constant airflow. Crack more doors in your home. Additionally, move any household items that may be obstructing your vents.

2. Take Shorter Showers

Make your morning shower short and sweet. You’ll save water and prevent your bathroom from becoming overrun with mildew. For added protection, turn on your bathroom vent during and after your shower to reduce humidity.

3. Use a Clothing Line

Take advantage of the warm weather to dry your clothes outdoors. Your dryer creates lots of humid air, particularly when it’s not properly ventilated.

4. Cook Carefully

Cooking food indoors can add to humidity levels. Before cranking on the burners, be sure your range-hood ventilator is open. Keep pots and pans hooded whenever possible. It’s also the perfect season for outdoor grilling.

5. Watch Out for Exposed Dirt

Your basement or crawlspace may be revealing a bit too much. Uncovered earth spots are common perpetrators of indoor humidity problems. Seek out any exposed earth surfaces, cover them with weighted material and seal them off. Also, be sure the area is well-ventilated.

6. Keep a Clean Chimney

If the chimney for your fireplace or water heater hasn’t been cleaned in a while, it could be contributing to humidity. If you think this may be the case, contact our specialists to have it cleaned right away. In addition to hindering airflow, clogged chimneys are a major fire and air quality hazard.

7. Get a Dehumidifier

Is your basement musty, no matter what you try? Time to dehumidify. Dehumidifiers convert moisture to water, restoring your air quality. Invest in a portable, or have one of our specialists fit your ductwork with a whole-house dehumidifier.

8. Close Off Areas With Lots of Moisture

Do you have an indoor greenhouse? Or an indoor pool? Be sure rooms that produce lots of humid air are properly sealed and insulated, so they don’t disturb the rest of your home.

9. Protect from Leaks and Flooding

Be sure you have sump pump maintenance performed annually. Clean your gutters. Additionally, seek out leaky culprits like pipes or water heaters. Remember—even a tiny drip can cause major water damage over time.

10. Maintain Your Air Conditioner

Your central AC system removes moisture from the air, converting it to liquid water. However, poor maintenance hinders its ability to provide you protection. Change your air filter once a month, and schedule seasonal maintenance to avoid mechanical problems.

Video – The Importance of Air Conditioner Maintenance

Fri, 28 Apr 2023 08:43:00 GMT

The best time of year to have your AC serviced is spring , even if you reside in a locale with pretty warm weather all year long.

What Does AC SEER Mean?

Wed, 19 Apr 2023 12:00:00 GMT

When it comes to your air conditioner (AC) , a common term used in the heating, ventilation, and air conditioning (HVAC) business you are likely to see everywhere is your air conditioner’s SEER . But what exactly is SEER?

SEER

SEER stands for Seasonal Energy Efficiency Ratio—a rating system of the air conditioner’s cooling capacity to power input. In technical terms, it’s the ratio of the amount of cooling produced (in British Thermal Units, or BTUs) divided by the amount of electricity (in watts) used. The higher the SEER, the greater the air conditioner’s efficiency.

According to the US Department of Energy (DOE) , heating and cooling units use more energy than any other system in your Conway, South Carolina , home. So when you are in the market for a new air conditioner, you will want to pay attention to the SEER level of the different units you are considering.

The higher the SEER number, the more efficiency bang you will get for your efficiency buck. This translates to money you save in the long run on energy costs.

The DOE requires residential air conditioner systems manufactured after January 1, 2015, to have a minimum SEER based on their location in the country. The country regions were divided in North and South, with the South being further divided into Southeastern and Southwestern regions. Minimum ratings range from 13 to 14 SEER.

Previously all systems manufactured after January 23, 2006, needed to have a minimum SEER rating of 13 (with the exception of window units, being exempt from this law). Older air conditioners have a SEER rating of 10 or under. You can usually find your system’s SEER rating on the yellow-and-black EnergyGuide sticker on the outside of your unit.

Saving Money by Upgrading

If your system is 10 to 15 years old but continues keeping you cool in the summer, you might still want to consider investing in a newer unit. By upgrading to a modern, more efficient model, depending on your current unit’s SEER, you could save quite a bit of money annually on your cooling bill.

To illustrate, say your current system has a SEER rating of 9. If you upgraded to an air conditioner with a 13 SEER, which is the lowest efficiency available, your power consumption would be reduced by 28 percent. Depending on how much you use your system and your cost of electricity, that could save you about $300 a year in energy costs.

The DOE has accessible online energy-efficiency calculators you can find to help you predict the energy costs you will save with different units carrying various SEER ratings. If you would like a more precise analysis, call Coastal Air + Refrigeration , and we would be happy to send one of our knowledgeable technicians out to go over the possible savings with you.

Which SEER Is for You?

To carry the Energy Star® label, an air conditioner must be in the top 25 percent of efficient models and have a minimum SEER of 14. But automatically purchasing an air conditioner with a higher SEER is not the go-to answer. Unfortunately, things are not that cut and dry.

The SEER rating represents the potential efficiency of the unit under perfect conditions. Much of the system’s efficiency depends on the right sizing of the unit for your home, along with correct installation and an evaluation of other factors as well. For example, your ductwork and windows may have leaks, thus directly affecting your energy savings.

Also, keep in mind your air conditioner does not operate within a vacuum. It’s directly tied to your furnace or heating system. Depending on what equipment you presently have and its age, this definitely factors into your air conditioner’s SEER rating.

Even though your proposed new unit has an 18 SEER, once married to your current furnace, the SEER may decrease to a 15 or 16. What you need to aim for is the right-sized equipment operating at its optimal ratings within varying conditions for the best savings and comfort for you.

Why Ductless Is the Way to Go

Wed, 15 Mar 2023 13:00:00 GMT

You deserve the most comfort at the best price in your South Carolina home or business. You want reliable heating, ventilation, and air conditioning (HVAC) at reasonable prices. You want fresh, clean air so you and your loved ones can enjoy a healthy home.

Try going ductless.

A ductless system , or mini split, adds comfort to your home without the hassle of having to extend your ductwork. For new construction, additions, retrofits, and remodeling projects, a ductless system is your perfect heating and cooling solution.

At Coastal Air + Refrigeration , we offer whole-house solutions that help you get the most out of your HVAC investment while adding value to your Myrtle Beach home. We believe you should have complete control when it comes to your indoor comfort, safety, and health.

Why Go Ductless?

Air ducts play a vital role in conventional heating and cooling systems—those ducts deliver the goods! But over time, tears and leaks develop in your ductwork that compromise efficiency. The US Department of Energy (DOE) estimates leaky ducts can add hundreds of dollars per year to your heating and cooling costs.

Most experts agree leaky ducts allow up to 25 percent or more of your energy to escape. A ductless system eliminates this type of energy loss.

How a Ductless Mini Split Works

There are two main parts to a mini split: an outdoor condenser and one or more indoor mounted units (additionally there is the conduit connecting the outdoor and indoor components). A few small holes and tubing are required to connect the outside refrigerant lines to the indoor units.

Our professionals at Coastal Air + Refrigeration can select the right mini split system to fit your needs and budget, and install it with minimal disruption to your home or office.

Zone Control Systems and Mini Splits

You might already know about zone control systems in which you can set different temperatures in different areas of your home. Zone control systems work especially well in large homes with multiple floors and intricate layouts.

With a ductless mini split system, you enjoy the benefits of a zone control system without the ductwork since each interior unit has its own programmable thermostat.

Advantages With a Ductless System

A ductless system uses a washable filter instead of a disposable filter, which is used in traditional system. Best practice involves cleaning the filter frequently—at least once a month, and more so if you have pets or smokers in your home. Annual maintenance tune-ups and inspections will help extend the life of your system and ensure it runs at full capacity when you need it most.

Here are some other advantages you will enjoy by going ductless:

Better air quality —Poorly maintained ductwork contributes to indoor air pollution, circulating dust and debris that infiltrates the air ducts through leaks and tears. Eliminating ductwork reduces the chances of exposing your indoor air quality (IAQ) to airborne contaminants.
More efficient —A quality central air conditioner has a SEER (Seasonal Energy Efficiency Ratio) rating between 14 and 16. A top-performing ductless system will typically have a SEER rating above 20.
Less noise — Central air conditioners and window units tend to make noise—not so with a ductless mini split. They’re quiet, efficient, and reliable.

Go Ductless Today!

Ductless mini split systems use less energy to provide all your heating and cooling needs in Myrtle Beach, SC . These innovative systems are environmentally friendly and simple to operate. At Coastal Air + Refrigeration, we take great pride in informing our customers about quality products and services that add comfort, safety, and health to your home or business.

Video – How Much Water Does a Leaky Faucet Waste?

Fri, 24 Feb 2023 14:32:00 GMT

A leaky faucet is a fairly obvious sign that there is something wrong with your plumbing. Signs include soggy floors, foundation cracks, water meter changes, or a mildew smell. One leak in itself doesn’t mean you need new plumbing necessarily but frequent leaks could be a sign of an aging pipe system.

Why Buying a Heat Pump Instead of a Furnace Makes Sense

Wed, 15 Feb 2023 22:18:00 GMT

Want to heat and cool your Myrtle Beach home, fight climate change, and save money—all at the same time?

Get a heat pump .

Under the Inflation Reduction Act of 2022, the federal government offers generous rebates and tax breaks to homeowners who buy heat pumps . The financial incentives aim to wean consumers away from fossil fuel-based home heating, such as natural gas furnaces, and steer them to efficient and environment-friendly electric heat pumps.

Heat Pump Rebates and Tax Credits

Federal rebates will reduce the price of the heat pump you buy. Depending on your South Carolina household income, you may qualify for a rebate covering the heat pump’s cost of up to $8,000. Regardless of household income, homeowners can get a federal tax credit of up to $2,000. Financial incentives also may be available locally.

From a financial perspective, there is no better time to switch from gas furnace heat to an electric heat pump system. Installing a heat pump also helps you prepare for a greener future at a time when states and local communities increasingly stress the use of electricity for home heating.

Some states have already banned natural gas altogether in new home construction.

You will be ahead of the curve if you install a heat pump in your Myrtle Beach home sooner than later. However, switching from your gas furnace to an electric heat pump takes a little planning.

If you wait until your furnace breaks down in winter, you may settle for whatever fits into your existing space and restores heat quickly. That may be another gas furnace. You may not have time to explore other options.

If your furnace is nearing the end of its useful service life, start planning now for its replacement. Our experts at Coastal Air + Refrigeration , your trusted heating, ventilation, and air-conditioning (HVAC) company, can show you how a heat pump can improve comfort and reduce your carbon footprint. We can recommend the best brand, size, and features for your Myrtle Beach home.

The Heat Pump Difference

An air-source heat pump works like an air conditioner in cooling mode. It extracts heat from the air inside your home and exhausts it outdoors, cooling your environment. When in heating mode, it moves heat from the outdoor air to inside your home.

A gas furnace burns fuel to create heat and creates byproducts, such as carbon dioxide (CO2) and carbon monoxide (CO), which it sends into the environment through a chimney or exhaust pipe. Heat pumps do not emit noxious gases. If solar, wind, hydro, or another clean energy source creates the electricity that powers your heat pump, no carbon emissions are involved in the heating process.

Transferring heat is more energy efficient than burning fuel to create heat. High-efficiency gas furnaces can convert 90 to 97 percent of the natural gas they use into heat for your home, with the other 10 to 3 percent lost through the exhaust pipe.

According to the U.S. Department of Energy (DOE), an air-source heat pump, when properly installed, can deliver up to three times more heat energy to a home than the electrical energy it consumes .

It is clear why the federal government and clean energy advocates are promoting heat pumps as essential to the nation’s electrification strategy. These dual heating-cooling systems save energy and help fight climate change.

They reduce monthly utility costs and simplify your HVAC system by serving heating and cooling needs. They also outpace air conditioners when it comes to humidity control.

What Are Signs I need a New Furnace?

Fri, 13 Jan 2023 19:47:00 GMT

A furnace is a major investment for any Conway homeowner. Although it’s not something that will need to be done frequently, most people will face the decision of needing to purchase a new heating system sometime during home ownership.

Our team at Coastal Air + Refrigeration wants you to understand how your furnace works and what signs you can watch for to indicate it’s time for a replacement heating system.

Time Has Passed

Perhaps one of the biggest factors in deciding it’s time to replace your furnace is its age. The average life span of a furnace is 15 to 20 years, but this can vary greatly depending on how well you have maintained your system. However, if your furnace is more than a decade old, it may be time to start planning for a furnace replacement.

Repairs Increase in Number, Cost, and Frequency

Another sign that it may be time to swap out your furnace for a new model is its repair record. As your furnace ages, you’ll find yourself calling in your South Carolina heating, ventilation, and air conditioning (HVAC) professionals more frequently. In addition, you’ll probably see the costs of service calls start increasing as well.

If your repair costs begin to reach half the cost of a new furnace within a year or so, it may be worth it to invest in a new heating system.

Utility Usage Rises

Keep an eye on your regular utility bills. If the unit cost of energy doesn’t rise but your monthly bills do, that may be another sign it’s time to replace your furnace. Older equipment tends to work less efficiently over time, which means it will require more energy to produce the same amount of heat.

One advantage of switching to a new furnace is that new models are always more energy efficient than older ones. As a result, you’ll automatically start recouping some of your investment in lower monthly utility bills.

For example, Money Magazine cites one possible example. If your annual heating costs are $2,000 and you increase your annual fuel utilization efficiency (AFUE) rating by 15 percent in a new furnace, you will save $300 each year. Naturally these numbers depend on your fuel and energy sources.

Excessive Humidity, Dust, or Dirt

Although many factors can play a role in indoor air quality , your furnace can definitely make a difference. If routine maintenance like changing your air filters and regular tune-ups do not solve humidity, dust, or other air quality issues, it may be a sign you need to replace your furnace.

Strange Noises or Odors

Be sure to be attentive to the daily behavior of your furnace. Often, buzzing, vibrations, clanking, or other noises may warrant a service call. If your professional technician finds your furnace has excessive wear or structural damage, it’s a wise decision to invest in a new furnace.

Change in Comfort Level

When you run your furnace, if your home doesn’t feel as comfortable as it has in the past, you may want to explore the causes. Older furnaces that are working inefficiently can cause different rooms in your home to vary greatly in temperature, leading to uncomfortable cold and hot spots. When you upgrade your furnace and its components to newer models, you may be able to boost the comfort level of you and your family.

Physical Appearance

Finally, you can take a quick inventory of your furnace’s physical appearance. If you see signs of rusting, cracks, or other structural weaknesses, it may be a smart idea to evaluate your new furnace options .

Video – What Is Carbon Monoxide?

Fri, 23 Dec 2022 20:22:00 GMT

Carbon monoxide is a poisonous, odorless, tasteless gas. It is formed by the incomplete combustion of carbon, or the incomplete burning of natural gas and other things that contain carbon. It can often be mixed with other gasses with odors. Carbon monoxide can result from the burning of any of these, gasoline, kerosene, oil, propane, coal, wood and other things. It is also a byproduct of an internal combustion engine.

The CDC estimates that 400 people per year die of carbon monoxide poisoning, 20,000 more visit the emergency room and 4,000 people are hospitalized.

Conventional HVAC or a Heat Pump: Which Is Better?

Wed, 14 Dec 2022 14:24:00 GMT

We all take climate control for granted these days. In winter, we expect warmth from our heating system; in summer, we demand the cool comfort of air conditioning. Most Myrtle Beach homeowners don’t give that a second thought—until the heating, ventilation, and air conditioning (HVAC) system breaks down and replacement decisions need to be made. Today, the majority of homes either use a conventional air conditioner (AC) and furnace combination or a heat pump. Our team at Coastal Air + Refrigeration is well-versed in the difference as well as the benefits of each type of system.

The Basics of a Conventional Furnace and AC System

In the case of a conventional HVAC system, two separate pieces of equipment share the job of keeping your comfortable. The air conditioner is electric and has both an indoor and outdoor component while the furnace can rely on different fuels to generate heat. The most common furnaces use electricity, natural gas, or propane to generate heat.

Furnaces and air conditioners share the components that circulate the conditioned air through your SC home. They both utilize the same blower fan, air duct network, and thermostat. Smart thermostats can help you micro-control your environment, and when used in combination with zone control systems, can deliver individualized comfort and increased efficiency. Newer, high-efficiency systems offer additional features such as variable-speed motors that can save you even more energy.

The Basics of a Heat Pump

A heat pump, on the other hand, is one unit that provides both heating and cooling to your home. A heat pump operates by essentially moving heat into or out of your home, depending on the season. In summer, the heat pump moves heat from inside your home to outside. A heat pump works in reverse during winter; it moves heat from outside to inside your home. Heat pumps are most popular in areas with relatively mild winters. Heat pumps can still heat your home in colder temperatures, however the amount of heat available outside may not be enough to keep you comfortable in colder climates.

The Best Situations for Conventional Furnace and Air Conditioner

Since furnaces generate heat using a fuel, they often perform better in colder climates. Homeowners in the coldest areas of the country can rely on their furnace to keep them comfortable all winter long, even on the coldest days. In some areas of the country, air conditioners are not needed, but more and more our expert installers are adding air conditioners in northern regions. With a furnace, you can choose to go with, or without, the added expense of an AC.

The Best Situations for a Heat Pump

Overall, heat pumps are more energy efficient and environmentally friendly than conventional furnace and AC systems. They simply use a smaller amount of electricity to perform the transfer of heat from one area to another, making them less expensive to operate. According to the U.S. Department of Energy , some homeowners might save up to half their annual energy costs by using a heat pump over a conventional furnace/AC combination. The potential savings is dependent on the cost of fuel in your region.

One type of heat pump is particularly efficient and sustainable: a geothermal heat pump. These heat pumps use the ground as a constant temperature source rather than depending on outdoor temperatures or burning of fossil fuels. They essentially use the earth’s natural temperature, which stays generally constant throughout the year, to heat and cool your home.

How a Whole-House Humidifier Keeps You Healthy

Mon, 14 Nov 2022 23:42:00 GMT

There are many advantages to adding a whole-house humidifier to your South Carolina home. Adding a humidifier can increase the comfort level in your home and lower your annual energy expenses. Proper humidity levels can allow you to maintain indoor comfort levels at a lower temperature which uses less energy for heating.

At Coastal Air + Refrigeration, our professionals will walk you through the design process and ensure that your Conway home is the ideal design to properly utilize a whole-house humidification system. We believe you should have total control of your indoor health, safety, and comfort—our mission is to provide you with practical solutions so that you can achieve that goal!

How a Humidifier Keeps You Healthy

Benefits to a properly installed whole-house humidification system include:

Soothing cold and flu symptoms by moisturizing your nasal passages and throat and bronchial tubes.
Reducing some allergy symptoms.
Relieving some dry skin conditions.
Lessening snoring.
Protecting wooden flooring and furniture from cracking due to low humidity.
Reducing utilities.
Increasing general comfort.

Between work and home, most of us spend the vast majority of our days indoors. According to the US Environmental Protection Agency, the concentrations of some indoor pollutants are often 2 to 5 times higher than typical outdoor concentrations .

Choosing a Whole-House Humidifier

You never want to buy a car that is too large for your garage—nor do you want to buy a humidifier that is the wrong size for your home! Similar to your other heating, ventilation, and air conditioning (HVAC) equipment, you want to be sure you are purchasing a humidifier system that suits your needs.

Here are a few types of humidifiers to choose from:

Bypass Humidifiers
Bypass humidifiers add moisture to air passing through your furnace or air handler. These types of humidifiers are the most basic of your options and pass the warm air from the heating system over the humidifier to collect the evaporating moisture.

The newly collected moisture is then distributed throughout your Conway home using your existing duct system. Because these units require a home heating system, they work much better with furnaces as opposed to heat pumps because of the higher air temperatures generated by furnaces.

Bypass humidifiers require a drain and water line for proper installation. They are the least expensive of your options for a whole-house system, but also deliver the lowest amount of humidification because they require system operation for evaporation.

Fan-Powered Humidifiers
The only real difference between a fan-powered humidifier and a bypass humidifier is the need to use the fan to increase airflow and therefore increase evaporation. Fan-powered humidifiers can produce up to a gallon more of humidity per day compared to bypass humidifiers. The internal fan motors within these units are also very efficient, using the same amount of energy as a 25-watt lightbulb. This system is considered much more efficient than bypass humidification systems.

Steam Humidifiers
Steam humidifiers create steam to input humidity in the HVAC system. They use electricity to boil the water. The steam is then distributed throughout your home using the existing airflow system. Steam humidifiers are the fastest and most efficient way to increase and maintain the desired level of humidity in your home.

Steam whole-house humidifiers also provide the purest and most natural form of humidity you can have within your home. They are also the most vulnerable to rapid corrosion and system damage due to poor water quality.

Advantages With a Whole-House Humidifier

Any whole-house humidifier is installed directly into your home’s central heating and cooling system. Location and ease of access to your humidification system is another important factor to consider. Your comfort adviser will review the different options for you, including the pros and cons of each type of system.

Once properly installed, a whole-house humidifier is less work than a portable one. Portables require constant monitoring of water tanks and regular cleaning. With a whole-house humidifier, you could perform routine maintenance as little as two times a year. This depends heavily on both proper installation and the quality of water going through your humidifier. If your water is heavily calcified, it will rapidly cause build-up on the humidifier and may require additional water purification devices for the humidifier to function properly.

A properly designed and installed humidification system can make a world of difference in your home but only if designed and installed properly. A poorly installed system can cause a world of headaches for the unsuspecting homeowner. Improper humidification and design can lead to mold throughout the home or attic.

Along with the installation of a humidification system, it is always important to make sure your ductwork is in proper shape to prevent unwanted bacterial growth. Equipment failure due to poor installation can lead to leaks and damage your home’s ceilings, walls, insulation, framing, or even roofing.

What’s That Sound Coming From My Furnace?

Fri, 14 Oct 2022 23:44:00 GMT

It’s normal for your furnace to make some noise. For instance, a dull hum is to be expected. However, louder noises might spell trouble for your heating unit’s components. Remember to turn off your furnace if it makes any alarming sounds and leave the repair job to a professional.

To help you, our Coastal Air + Refrigeration team here in Myrtle Beach made a list of six common furnace noises, what might be causing the noises, and what to do if you hear them.

1. Loud Banging

If you hear a loud banging noise, you should turn off your furnace right away. This might mean you have dirty burners that cause gas buildup in the ignition. A heating, ventilation, and air conditioning (HVAC) technician should clean your burners once a year during a maintenance inspection.

Another culprit could be your vents expanding and contracting due to temperature change. No matter the cause, you should have one of our professionals inspect the problem right away. Internal equipment knocking around could lead to a cracked heat exchanger, which is grounds for replacing your furnace as stated by the American Gas Association .

2. Screeching

When your furnace is low on lubricant, this can produce a high-pitched screeching or squealing sound. The bearings and/or belts are squeaking and need to be oiled. It’s best to give one of our HVAC professionals a call, since you can’t lubricate your furnace sufficiently with common household oils.

3. Rhythmic Metallic Clanging

If your ears detect a clanging or thud repeating in a rhythmic fashion, there’s probably something caught in the blower blades. If you hear this noise, power down your furnace and inspect the blades to see if a foreign object has made its way into there. If you can’t see anything, give us a call to help.

4. Metal Scraping

When your blower fan comes loose, it scrapes against other metal components creating a shrill noise. In this case, you should turn off your furnace immediately to prevent further damage. If you catch it early on, the repair should be pretty simple and inexpensive. Leave it for too long, and the repair could be more serious.

5. Recurring Clicking Noise

This sound might be harder to pick up on, so you should pay careful attention. It might mean you have a defective relay switch, which is the component sending electricity to the heating parts and motor.

Another possibility is your flame might be having trouble staying lit. A misaligned or dirty thermocouple can prevent the flame from staying lit. Or a bad gas valve could be the culprit. Either way, call one of our professionals as soon as possible to keep your furnace and North Carolina home in good condition.

6. Low-Pitched Growl

This is another sound you may not notice. It’s the sound of extra combustion occurring, which could be caused by dirty gas burners or a misplaced pilot light. No matter the cause, this scenario requires a professional’s attention.

Video – What Is a Heat Pump?

Fri, 30 Sep 2022 12:08:00 GMT

A heat pump is a device that transfers heat from one place to another, from inside your home to outside or from outside to inside. In the winter a heat pump works like a heater, extracting heat energy from outside and transferring it inside. In the summer the process reverses and it will remove heat from your home and transfer it outside similar to an air conditioner .

Think HVAC During Your Home Remodeling

Fri, 09 Sep 2022 13:36:00 GMT

Congratulations, you’re planning to remodel your Conway home! Breathing new life and comfort into your charming older home is a grand adventure, and you can count on our team at Coastal Air + Refrigeration to be there every step of the way to help however we can.

But before you begin picking out the paint colors and fabric swatches, don’t forget about your heating, ventilation, and air conditioning (HVAC) equipment. Upgrading your heating and cooling system can lower your monthly utility bills by more than 40 percent. And the best time to replace older equipment is when you are updating your home.

Coastal Air + Refrigeration is your trusted source for all your HVAC services in Conway, SC. We install, replace, repair, and maintain all brands and models. Give us a call today for a free consultation about your next home project.

Why Upgrade Your HVAC Equipment

Most homeowners wait until their heating and cooling system is on its last legs before they replace it. That’s a mistake. After the 10-year mark, your equipment starts to wear down. The energy bills go up, and the repairs become more frequent.

Unless your system is relatively new, replacing it while remodeling makes a lot of sense. The equipment you now have is based on the square footage of your home. If you are adding new living space, that equipment is going to work extra hard to keep you comfortable.

The same goes with your air ducts . Most ductwork, over time, tends to lose up to 30 percent of the airflow because of leaks and tears. A remodeling project allows you to seal those leaks and patch any tears.

Tightly sealed ductwork helps your equipment run more efficiently and improves your indoor air quality (IAQ). Be sure to ask about our convenient financing options that make it possible to create a dream home for your loved ones.

HVAC Remodeling Ideas

Plan ahead when it comes to upgrading your HVAC equipment. Think about adding new fan venting for your kitchen and bathrooms. Create a zone control system with your ductwork that allows you to set different temperature zones around your home. Take control of your energy use by upgrading to smart thermostats.

For a new addition, consider upgrading your furnace , air conditioner , or heat pump . You can also install a ductless mini split system in parts of your home without ductwork—such as the basement, garage, or attic.

HVAC Refrigerant and SEER Changes in 2023

Wed, 03 Aug 2022 16:17:00 GMT

Are you shopping for a new heating, ventilation, and air conditioning (HVAC) system in Myrtle Beach, SC , or the surrounding area?

If so, you will want to read this first.

The U.S. Department of Energy (DOE) will raise the minimum efficiency requirements for central air conditioners and air-source heat pumps starting in 2023. Systems sold in the U.S. beginning January 1, 2023, must meet those minimum standards.

Additionally, in 2023, the U.S. Environmental Protection Agency (EPA) will begin phasing down the manufacture and importation of R-410a, a commonly-used refrigerant for residential cooling systems.

The two changes will create a new generation of HVAC systems designed to be more efficient and eco-friendly. But you’ll also pay more to enjoy these new features, a factor to consider if you plan to replace your equipment in the next few months.

Coastal Air + Refrigeration is a trusted name for providing quality HVAC service to Myrtle Beach households and businesses. Give us a call for any questions you have about your next home improvement project!

What Is SEER and How Does it Impact HVAC Systems?

The seasonal energy efficiency ratio (SEER) measures cooling system efficiency. The higher the number, the better the efficiency.

Beginning next year, SEER ratings for AC units and heat pumps will increase from 13 to 14 in northern states and 14 to 15 SEER in the South and Southwest regions of the country.

In terms of heating efficiency, air-source heat pumps will increase from 8.2 to 8.8 HSPF (heating seasonal performance factor).

The increase in efficiency means you will use less electricity for the same amount of cooling. Your Myrtle Beach home’s carbon footprint will shrink, and so will your utility bills . But you can expect manufacturers to increase prices to accommodate the new SEER ratings.

Is your cooling system more than eight years old and less than 15 SEER? Now is the perfect time to replace it before prices increase next year. Why keep outdated, obsolete equipment that will drive up your electric bills? Call Coastal Air + Refrigeration today for a free consultation and upfront pricing.

What Is SEER2?

SEER2 represents new testing standards for cooling systems beginning in 2023. The testing standards give consumers a more accurate picture of how an installed HVAC system will perform.

Similar to the changes in the SEER rating, these new testing standards do not impact your current system. But they will drive up purchase costs in the future. The new testing requirements mean any equipment the manufacturers produce must now adhere to SEER2 standards.

New Refrigerants in 2023

Since 2010, residential cooling systems have contained a refrigerant called R-410a, a hydrofluorocarbon (HFC) that has high global warming potential and could harm the environment if it leaks from a cooling system.

For that reason, the U.S. Environmental Protection Agency (EPA) is phasing down the manufacture and importation of HFCs by 85 percent over the next 15 years.

Beginning next year, new cooling systems will contain a refrigerant called R-454b with a lower global warming potential.

This refrigerant is more environment-friendly than its predecessors but also mildly flammable. You can rest assured our Coastal Air + Refrigeration technicians know how to handle it safely.

What If My Cooling System Uses R-410A?

Although R-410a will be available for equipment repairs over the next few decades, no new air conditioners or heat pumps will contain R-410a beginning in 2023.

You do not have to replace any equipment because of the new refrigerant changes.

A well-maintained AC system will last 15 to 20 years. If you need a new unit, buy it this year. There should be enough R-410a to last the life of your system, but the cost of replacing the refrigerant might creep up eventually if you need a repair.

Can I Retrofit My AC to Use R-454B?

No. Refrigerants operate at different pressures. An R-410a air conditioning or heat pump system will not be calibrated to use R-454b.

Even if you could retrofit your equipment to handle different refrigerants, the cost of doing so would likely approach the price of a new system. Plus, you would more than likely void your existing warranty.

You can save money immediately on utility bills by upgrading today to a high-efficiency system. Plus, you’ll pay less in purchasing costs. Otherwise, wait until 2023 to buy a system with the new refrigerant and SEER ratings. Our trained professionals can walk you through the pros and cons.

How to Unclog a Drain

Wed, 06 Jul 2022 19:16:00 GMT

It’s bound to happen to Conway homeowners sooner or later—a clogged drain. Although clogged drains are often a nuisance, they can many times be managed at home with inexpensive solutions.

Our team at Coastal Air + Refrigeration wants to share some affordable, effective ways to unclog a home drain as well as tips on preventing the problem in the future.

Typical Causes of Drain Clogs

Most South Carolina homes have multiple drains throughout the interior of the house, plumbing that connects them to a main line and a larger, outdoor line that feeds into a city sewage system or septic tank. Clogs can unfortunately happen just about anywhere throughout this complex system.

The most common clogs occur just under the kitchen or bathroom sink. This is why you will find an elbow joint designed to catch foreign material before it makes its way further down the pipeline.

Kitchen clogs will typically be made of small particles of food, grease, and dirt. Bathroom sink clogs usually consist of hair and soap residue. You may have the same type of clog in your shower drains as well.

Toilet clogs can be caused by large amounts of toilet paper being flushed down at one time. Occasionally, nonflushable products such as facial tissue, toilet paper, feminine or baby products, or even foreign objects like toys can clog the toilet drain.

Larger clogs around bigger appliances such as a washing machine or dishwasher are more rare but also more difficult to clear. Items such as rocks, coins, safety pins, and fiber buildup can clog your washing machine drain.

If your dishwasher seems to be clogged, check the filter basket, which is designed to keep food scraps from getting into your pipes. If cleaning out the basket doesn’t help, you can check the hose that connects the dishwasher to your kitchen sink drain for blockage.

At some point, if you notice all your sinks, toilets, and appliances are not functioning properly, you probably have a clog in your home’s main line that sits between your home and the main sewer line. This can be caused by tree roots, outdoor dirt, or yard waste accumulation as well as foreign materials from inside your home.

Home Remedies

Before you run to the store for a harsh, commercial drain cleaner, try some of these gentler methods of unclogging a drain. The chemical drain cleaners may be ineffective, can damage your pipes in the long run, and are not always healthy for your family or the environment.

Pull out any visible clogs from the sink itself first. Then, you can pour boiling water down the drain with some salt. This can be effective for grease clogs. For some additional power, let a fizzy mix of vinegar and baking soda sit in the drain for a few minutes before adding the boiling water.

For toilet clogs, use a quality plunger and be sure you have a good seal to maximize the suction. You could also try a drain snake or an auger, but be sure you use a properly sized tool for the specific job.

For washing machine clogs, you can try an enzyme-based drain cleaner to eat through the clog.

If you are mechanically inclined, try to empty the drain trap under sinks.

When these remedies don’t work, you need a professional plumber to handle the issue. Call our Coastal Air + Refrigeration plumbers to come out and help.

Preventive Measures

After you unclog your drain, or before you ever get a clog in the first place, here are some tips to prevent this annoying problem.

Be sure you have drain catchers or strainers in all your drains. These inexpensive and easy-to-clean gadgets can prevent food, hair, and other debris from escaping down your drains in the beginning.

Run some hot water through your drains daily, and every once in a while, flush drains with baking soda and vinegar.

If you have a garbage disposal, be sure you only use it for small pieces of nonfibrous, nongreasy foods. Follow your instruction manual, or check out general guidelines from an informational website .

Common AC Purchasing Mistakes to Avoid

Tue, 14 Jun 2022 14:35:00 GMT

When it’s time to invest in a major home appliance like an air conditioner (AC), you want to be well informed. The good news is technology has made it easy to gather a great deal of information in a short period of time. The bad news is there are so many makes and models of air conditioners available, the entire process can get quickly overwhelming.

Our professionals at Coastal Air + Refrigeration would be happy to help you sort out the options and help you make a smart investment. In the meantime, here are some top purchasing mistakes to avoid while you are doing your research.

Equating a Big Unit to More Cooling

It’s easy to want maximum cooling power, especially during the summer months in South Carolina . However, bigger does not always mean better in the case of air conditioning systems.

According to Home Energy magazine, air conditioner loads should be calculated carefully to select the right-sized air conditioner for your home. Our trained professionals can utilize Manual J load calculations and take into account the design and age of your Myrtle Beach home. We also assimilate the average temperatures and length of your summer to recommend the best air conditioner for your situation. Making the right decision will give you the highest level of comfort with the most efficient use of energy, resulting in lower operating costs over the life of your system.

Choosing the Least Expensive Unit

Air conditioners come in a wide range of designs, from basic cooling to integrated smart-home technology. The price range reflects the vast differences in makes and models. While purchasing price needs to play a role in your air conditioning selection, be sure it does not dictate your entire decision. You want to be sure your unit is appropriately sized for your home and provides you with the features and power you need.

In addition, you will also want to look at the overall operating costs, not just the initial purchase price. Many higher-priced units run more efficiently over the long run, saving you money every month on your energy bills.

Selecting the Cheapest Air Conditioning Contractor

It’s understandable that you want to get the most service for your money. However, when it comes to installing a major system like an air conditioner, you don’t want to cut corners. Be sure you select an experienced professional who is bonded, insured, and licensed, like ours at Coastal Air + Refrigeration . In addition, you may ask to see North American Technician Excellence (NATE) certifications for technicians. Going with the least expensive provider may lead to more expensive problems down the road.

Making Only a Verbal Agreement

Be sure to ask for a written statement of work, which should include an estimate, scope of work, time frame and schedule, and warranty information. The written agreement should also include payment terms including how much is due up front and when final payment is required. This step simply provides clarity to all parties involved and can help you avoid disputes later.

Replacing Partial Air Conditioner Unit

It’s always a balancing act to determine whether repair or replacement is the best option when your air conditioner breaks. However, once you make the decision to replace, it’s important to replace both the indoor and outdoor components at the same time. Replacing only one will most definitely affect the efficiency of the entire unit and may cause additional problems later on.

In addition, you may want to consider replacing your entire heating, ventilation, and air conditioning (HVAC) system all at once if your entire heating and cooling system is old or causing regular problems. Selecting an overall HVAC system that fits your home can ensure comfort year round.

Video – What Are Common Mistakes Made When Purchasing a New AC?

Tue, 31 May 2022 14:39:00 GMT

It’s time to replace your old or broken AC unit in your home and you don’t want anything to go wrong with the new one. Avoid the common mistakes people make when purchasing a new air conditioner and learn how to prevent them.

3 Telltale Signs It’s Time for a New AC

Wed, 04 May 2022 18:28:00 GMT

Should you repair or replace? That’s always the big question when it comes to major home systems like air conditioning (AC). Repairs are easier on the pocketbook in the short run, but too many of them can add up.

Deciding on the ideal time to replace your air conditioning system in Conway can be a challenge, so here are three areas our Coastal Air + Refrigeration professionals suggest you monitor for telltale signs:

1. Check the age of your air conditioner.

Most air conditioners have an average life span of 10 to 15 years with regular usage. If you run your air conditioning system constantly through unusually hot summers, you may shorten that life span. On the other hand, lighter usage or cooler weather may mean your unit lasts significantly longer.

Although age alone does not signal an automatic need for a new air conditioner, it should play a factor in your decision. If you notice your current unit is not performing as well and you require more repairs on a system that’s reaching the end of a typical life span, it’s probably a good time to make the investment.

2. Evaluate the performance and energy efficiency.

Pay attention to how your air conditioner is performing, as well as to your energy bills. If you have taken care of your air conditioning system with regular maintenance , but begin to notice the unit is not cooling as quickly, as well, or as evenly as it used to, this may be a sign that it’s time to look for a new air conditioner.

In addition, take a close look at the cost of running your air conditioner. New units are always more energy efficient than older ones, and technological developments often boost performance of the newest models. According to the US Department of Energy (DoE), high-efficiency air conditioners can reduce energy usage by 20 to 50 percent per year.

3. Gauge your home’s air quality.

A well-functioning air conditioner should not only keep your home cooler, but it should also improve your air quality by reducing the humidity and minimizing allergens such as mold. When the weather is particularly humid in SC, your air conditioner will have to work much harder. Not only will your system need to remove heat, but it will also need to remove moisture from the air.

Over time, this will tax your air conditioning system, making it more difficult to handle humidity. If you notice more moisture in your air, as well as decreased air quality, you may want to invest in a new system.

Why Is My Air Conditioner Freezing Up?

Sat, 30 Apr 2022 13:38:00 GMT

If your air conditioner stops blowing cool air or stops all together, check to see if your indoor unit is frozen. What exactly will that look like?

A freeze up is when a layer of ice forms on the outside of your air conditioning unit. It can look a bit disconcerting, but don’t panic. It’s fixable. Whether you have a central air system or a window unit, the causes and effects, as well as the solutions, are the same.

The ice buildup on your air conditioner creates the inability for it to cool effectively and puts stress on the compressor (your outdoor unit if you have central air conditioning). Over time, this can lead to a costly repair or the need to replace the compressor.

At Coastal Air + Refrigeration , we can help. First, let’s explore a number of the possible reasons for the freeze up:

Insufficient Airflow

Anything restricting the airflow in your unit will cause the system’s evaporator coil to freeze. There are a few reasons your air may not be flowing efficiently. The most common problem is a dirty air filter. If you are running your air conditioner continuously, we recommend replacing or cleaning the air filter once a month. Other airflow problems include blocked or closed ducts and vents, a faulty fan, and/or dirt on the evaporator coil. Evaporator coils need regular cleaning, and we recommend a cleaning once a season.

Low Refrigerant or Freon®

Another thing that causes an air conditioner to freeze is low refrigerant or Freon. This causes a drop in pressure inside the evaporator coil, which then allows moisture in the air to accumulate and freeze on the coil. A leak is typically responsible for low refrigerant. If the cause of your freeze up is low refrigerant, you need to contact one of our trained and experienced technicians to assist you in the repair. This includes finding and repairing the leak, then refilling your refrigerant to its proper level.

Outdoor Temperature

Air conditioners are designed to run in a specific temperature range. Most of them will not run well when the temperature outdoors is below 60°F. Often a freeze up occurs because the nighttime temperature here in Myrtle Beach, SC , is dropping too low for the unit to function properly. When the air is too cool, the pressure inside the system drops and causes a freeze up.

If your air conditioner freezes, turn it off. Let your unit thaw a while. One of our professionals will be able to work on it as soon as the ice has melted completely.

Do I Really Need an AC Tune-Up?

Thu, 31 Mar 2022 09:00:00 GMT

Home ownership comes with a great deal of responsibilities and an ever-growing to-do list. Add to that the responsibilities of a career and a family, and you see why modern life runs at a constant, fast pace here in Conway . It’s easy to bump things like an air conditioner tune-up down the priority list, both in terms of time and money. It’s very likely you have higher priorities requiring more urgent attention than an air conditioner that seems to be working just fine.

Our professionals at Coastal Air + Refrigeration understand that line of thinking but want to be sure you realize the long-term benefits of regular maintenance and tune-ups for your air conditioning system . In many cases, a small, short-run investment can save time, money, stress, and hassle down the road.

Extend Your Air Conditioner System’s Life

Just like all appliances, air conditioners have an average lifespan. According to the US Department of Energy (DOE), air conditioners have an average life of 15 to 20 years . If you consider air conditioning systems that are abused or neglected may not make it to quite 15 years while those that are well maintained may exceed 20 years, you have a significant span of time when you won’t need to invest in a new unit.

An air conditioner tune-up can help more permanent components last longer, because they are not working hard to battle things like dirty filters and unlubricated parts. A new air conditioning system is a costly investment; make it last as long as possible with a regular air conditioner tune-up.

Minimize Emergency Repairs

In many areas of the country, the hottest days of the summer require air conditioning to keep families safe and comfortable. A regular air conditioning tune-up can catch problems before your air conditioning simply stops working. If your air conditioner is pushed to that point, you may incur high emergency-repair costs and face stressful, uncomfortable, and potentially dangerous heat.

An average repair bill may be two to 10 times higher than a maintenance call. In addition, many heating , ventilation , and air conditioning (HVAC) companies and contractors get much busier in the hottest of days because of other emergency calls.

Reduce Energy Bills

Installation, maintenance , and repair costs are only part of the equation when it comes to your air conditioning system. The ongoing cost is in terms of your monthly energy bills.

If you are running an inefficient, dirty air conditioning system, it will not be operating efficiently, which means you are paying more than you need to in terms of energy bills as well as using precious natural resources at a faster rate. Regular maintenance and tune-ups are usually reasonably priced, and you will recoup much of the cost on lower energy bills.

Take Advantage of Expert Eyes

A reputable HVAC company , like Coastal Air + Refrigeration, will employ trained, experienced technicians who bring expert eyes to your system along with a tune-up checklist. In a short period of time, usually an hour or two, you will be able to take advantage of an experienced professional who will give your air conditioning system a complete inspection, cleaning, and examination.

Many tune-ups include:

Cleaning and inspecting air conditioner condenser coils
Checking and adjusting coolant levels to achieve efficient operation
Lubricating all bearings, components, and other moving parts
Inspecting air duct work for leaks and damage
Tightening connections within electrical system
Observing condition of blower motor and belt, and repairing or replacing, if needed
Testing thermostat
Changing or cleaning filters
Checking fittings and safety equipment

Video – Do I Need to Schedule a Maintenance Appointment?

Wed, 02 Mar 2022 10:00:00 GMT

Regularly scheduled maintenance can help you catch symptoms of bigger problems before they become an issue for your business. Catching symptoms of trouble early on can keep your units working efficiently and safely as long as possible.

Just like a regular physical, a regularly scheduled maintenance appointment can help find and diagnose problems that would be otherwise invisible to you because the signs are not easily seen or heard. So often we notice problems only because we miss the benefit we lost when something stops working.

Why Do I Need AC Maintenance Now?

Tue, 01 Mar 2022 10:00:00 GMT

An air conditioner (AC), just like a car, needs regular maintenance and service to run efficiently. At Coastal Air, we recommend getting your air conditioning unit serviced and cleaned at least once a year. The optimum time is in the spring to ensure your system will run with the most efficiency during the hottest summer months. You need to be able to rely on your air conditioner for your comfort here in Myrtle Beach.

Why Is Maintenance Important?

The short answer is it saves you money!

Your air conditioner collects dust and dirt continuously as it sits throughout the year here in South Carolina, not only in the months when it’s running. Though this tiny debris may not seem harmful, when it accumulates throughout the year, it can make its way into the cracks and crevices of your unit, as well as everywhere else. This creates gunk and wreaks havoc on the different parts involved in the cooling process.

When this happens, parts break down much sooner than expected and can add up to costly repairs. It also decreases the life expectancy of your heating, ventilation, and air conditioning (HVAC) system, forcing you to purchase a new air conditioner much sooner than you may have planned.

Regular air conditioning maintenance also supports your system’s energy efficiency. Simple acts you can perform yourself, like replacing a dirty and clogged air filter, can reduce your energy consumption by 5 to 15 percent, according to the US Department of Energy (DOE).

This translates to you spending less money on your utility bills. Professional and DIY maintenance alleviates higher bills and keeps your air conditioner working at its manufacturer’s intended efficiency.

Even if you are fastidious with doing your own regular home maintenance , you should always have your unit cleaned and checked in the spring by one of our professionals (if not more throughout the year).

There are many tasks only a professional technician is trained and certified to perform. Neglecting these professional tasks constitutes poor maintenance and will negatively affect your system in the long run, again, costing you money. This typically also voids your system’s manufacturer warranty.

What Can I Expect My Technician to Do During My Regular Maintenance?

Here’s a brief overview of what our knowledgeable and experienced technicians do during your air conditioning maintenance appointment:

Clean and check condenser coils and evaporators, if necessary.
Clean and adjust blower components for proper system airflow to create increased comfort levels.
Check ducts for debris, and if debris is present, remove it to allow for maximum airflow.
Clean and check aluminum fins. If they are crushed or bent in any fashion, this affects proper air distribution.
Inspect internal parts for broken, chipped, or other damage, which may not be easily noticed. If your air conditioner continues to run with damaged parts or areas, your system will eventually fail.
Clean and check condensate drain, to prevent any blockages or mold buildup. Backups can cause water damage to equipment.
Tighten connections, both mechanical and electrical. Loose connections cause incorrect operations.
Check the coolant level for leaks. Leaks prevent your air conditioner from working, and the refrigerant could damage anything it touches.
Check the system’s thermostat for accuracy.
Check system controls to be sure all work safely.
Provide you with a summary of work performed and share any findings regarding needed repairs or upgrades, as well as maintenance you can perform yourself between maintenance visits.

Video – How to Prevent the Pipes in Your Home From Freezing

Thu, 17 Feb 2022 10:00:00 GMT

Insulate the pipes in your home on exterior walls or in unheated areas such as crawl spaces, garages, basements, and attics. Turn off the inside water shut-off valve that provides water to your outside spigots or hose bibs. Drain each line by opening the spigot until it stops dripping and then turn off the spigot. Use a faucet cover to insulate the outdoor spigot and further protect it from freezing. Seal windows or any cracks that would bring in a draft.

What’s the Difference Between My Furnace Fan Settings—ON and AUTO?

Mon, 31 Jan 2022 10:00:00 GMT

There are furnace-fan settings on your thermostat for ON and AUTO. Which option is the best choice? There are devotees of both settings, each believing their setting is the optimum one to choose.

But in reality, it’s more of a pros-and-cons type of situation. It really depends on which benefits are a priority for you. If you need help making the decision, call our Coastal Air + Refrigeration team in Carolina Forest and talk with one of our knowledgeable professionals.

What’s the Difference?

If you have your thermostat’s furnace fan (or air-conditioning fan for that matter) set to ON , the fan will continuously run, regardless if your furnace is running through a heating cycle, i.e., whenever your furnace is actually producing heat.

If you have your furnace fan (again, or air-conditioning fan) set to AUTO , your system’s fan will run during the furnace’s heating cycle only. When your system reaches the temperature you’ve set for it, the fan will shut off until the next cycle.

Upside of Each

Here are the pros of each choice:

ON option

Air is always being cycled through your furnace filtration system when your fan is continuously running. The result is increase indoor air quality , since particles are constantly being removed from your air.
Keeping the fan running also means heating is more evenly distributed throughout your South Carolina home. No pockets of hot and cold. This also improves the reliability and life span of your system due to decreased starts and stops, somewhat like a car with highway or city driving. Less wear and tear.

AUTO option

Since the fan only runs when the system tells it to and at the slowest speed necessary for heating, it’s consuming less energy than the ON option. This translates to decreased energy costs and less money spent by you. Your furnace filter will also last longer, since air isn’t being pushed through it as much.

Downside of Each

Here are the cons of each choice:

ON option

The biggest con to having your fan continually running is the cost involved. It’s going to be expensive (unless you have a variable speed motor), much more than it would be on the AUTO option.
This downside may not affect you as much if you purchase a new system after July 2019. According to the online heating, ventilation, air conditioning, and refrigeration (HVACR) magazine, The ACHR News , the US Department of Energy (DOE) requires h eating, ventilation, and air conditioning (HVAC) manufacturers to comply with the DOE’s new energy conservation standards for residential furnace fans starting July 3, 2019. They predict it will, among other things, save Americans more than $9 billion in home electricity bills through 2030. So if you like the ON option and your furnace is getting older, purchasing a new system now may save you money in the long run.
Another downside of the ON option is you’re going to be replacing your furnace filter more frequently, since your air is being continually cleaned.
Also, in the winter, you may feel a little cold from time to time. Since the fan is running even when the furnace isn’t running through a heat cycle, cold air will be blowing through your vents during that time.

AUTO option

With this option, since there are more starts and stops, there will be more wear and tear on the furnace. With all these starts and stops, there’s also less even distribution of heat. Once the furnace stops, the air is no longer being moved around, resulting in cold spots. Also, since your air isn’t being filtrated 24/7, your home’s air isn’t as clean.

What Are the Basics of Furnace Filters?

Wed, 15 Dec 2021 10:00:00 GMT

Furnace filters. They’re one of those items not really on the top of everyone’s minds, but they are important and can have a big impact. At Coastal Air + Refrigeration , we know with the right furnace filter, you can save money and improve your Conway indoor air quality (IAQ) in one fell swoop.

What Does a Filter Do?

The primary function of your furnace filter is simply to remove particles from the air moving through your ductwork . This particle clearance protects your furnace’s blower fan and air conditioner , as well as you (by preventing the recirculation of the contaminants into the air you breathe).

The particles collect on the filter, which is why it’s so important to regularly change or clean it. If your filter is full, this dominoes into a host of problems––your furnace can no longer work at full capacity, damage to your furnace, and decreased indoor air quality . Obviously, each of these issues has its own ramifications as well.

What Types of Filters Are There?

When standing in the furnace filter aisle at your local South Carolina store, it is understandable to be overwhelmed. But breaking it down to basics, there are typically five different types of filters:

Disposable fiberglass
Disposable pleated
Disposable electrostatic
Permanent electrostatic
High-efficiency pleated

When deciding which filter to purchase, consider its overall cost, its purpose for contingent factors like pets or allergies, its minimum efficiency reporting value (MERV) rating, its size, and your furnace’s manufacturer’s recommendations.

Each filter type performs differently and has different costs involved—both short term and long term. Call our professionals at Coastal Air + Refrigeration to discuss which of these would work best with your heating , ventilation, and air conditioning (HVAC) system.

How Often Do You Replace a Furnace Filter?

There is no one answer to this question due to all the factors involved. When using cheaper disposable filters, they’re going to need replacing much more often, depending on if there are pets or a smoker in your home.

Obviously the disposable filters need replacing throughout the year typically three to four times, whereas the permanent ones just need cleaning throughout the year and, depending on type, can last from one to eight years.

A good rule of thumb is to check your filter monthly. If it’s looking clogged and dirty, replace or clean it. It’ll save your HVAC system, your bank account, and your lungs in the long run. According to US Department of Energy (DOE), replacing a dirty filter can lower your air conditioner’s energy consumption by 5 to 15 percent annually .

Can You Recycle Filters?

Everyone knows recycling makes your global footprint smaller. That said, unfortunately you can’t put your used disposable filter in your recycle bin.

Depending, your filter can be made from a combination of plastic, fiberglass, and wire mesh, although some are straight up one material. Furnace filters just aren’t candidates for your general recycling.

Now home air filters can be recycled by specific companies, but this is usually a mailer-type situation. If you’re concerned about your global footprint, investigate using permanent filters instead of disposable ones.

Heat Pump Maintenance Tips

Tue, 30 Nov 2021 10:00:00 GMT

Most of us tend to take our heating, ventilation, and air conditioning (HVAC) systems for granted. As long as they are working, it’s easy to go on day after day without thinking about them. But, like most other things, taking care of your HVAC system through regular maintenance is critical to keeping it in good working order

Many Myrtle Beach homeowners today have installed a heat pump to handle their heating and cooling needs. If you have a heat pump, you’ll want to be aware of some special considerations when it comes to regular maintenance issues. Our team at Coastal Air + Refrigeration offers the following information and tips to help.

Heat Pump Basics

Let’s start with understanding a little bit about how a heat pump operates. Heat pumps are typically more popular in areas with milder temperatures. They operate by essentially moving heat from outside to inside in the winter and inside to outside in the summer.

Since heat pumps do not have to generate heat by consuming electricity, natural gas, propane, or another fuel, they are more energy efficient. According to the US Department of Energy (DOE) , heat pumps may reduce your electricity usage by nearly 50 percent when compared with furnaces or baseboard heating units.

Heat pump technology continues to develop, and high-efficiency units can now operate reasonably well in climates with more extreme temperatures.

Air Filter Changes

One of the easiest maintenance tasks you can perform is to change your air filter regularly. Just like in all HVAC systems, the air filter in a heat pump is responsible for cleaning the heated or cooled air before it’s delivered to the rooms of your South Carolina home.

Basic air filters will remove larger particles of dust or dirt that float through the air. Choosing a high-efficiency filter like a high-efficiency particulate air (HEPA) filter will remove most of the smallest particles including pet dander, pollen, and dust mites.

Clean air filters not only result in better air quality but also help your heat pump operate more efficiently. That means lower energy bills and a longer equipment life span.

Proper Installation

Hopefully your heat pump was installed properly originally, but it’s not a bad idea to double check some important requirements. First, your heat pump should be at least four to six inches off the ground. This helps ensure the unit is not obstructed by the ground itself and allows for proper drainage.

Second, your heat pump should not sit under a leaking gutter. If your gutter began to leak after your heat pump was installed, you may want to prioritize that repair for the sake of both your gutter and heat pump.

Provide Plenty of Room

If your heat pump gets covered in snow, ice, overgrown plants, or yard debris, it will malfunction. It’s a good idea to spend some time inspecting the area around your unit during every season.

During the winter, snow or ice that accumulates on the heat pump must be removed. If a normal thaw or a simple brushing is not enough, you’ll want to turn off your unit and allow it to completely power down.

At that point, you can pour warm (not hot) water over the unit to melt the snow and ice. Be sure not to try to chip off the snow or ice using any type of tool, because you can easily damage the heat pump. Once the unit is clear of snow and ice, turn it back on.

In the other seasons, be sure to keep weeds, grass, and other nearby growth trimmed and out of the way. You’ll also want to clean things like fallen leaves, stray branches, or other yard debris that may gather on top of or under your heat pump.

Be Gentle During Cleaning

If you want to wash off your heat pump in the warmer weather, be sure to use your garden hose, not a power washer. The fins on the heat pump coil are delicate, and a jet of water can easily damage them. At the same time, it’s important to keep the outside of your unit clean and free of dirt, cut grass, or other debris.

Rely on the Professionals Annually

Since heat pumps operate on a 240-volt circuit, they are extremely dangerous for amateurs to work on. It’s a good idea to have your unit inspected, professionally cleaned, and tuned up annually by one of our trained and certified HVAC professionals.

Our experienced technicians will inspect your entire heat pump system including ductwork , airflow, refrigerant charge, electric terminals, thermostat , and more. A regular maintenance call will go a long way in helping to keep your unit operating well all year long.

4 Reasons to Replace Your Home’s Air Filter

Fri, 29 Oct 2021 09:00:00 GMT

Heating , ventilation, and air conditioning (HVAC) filters and the late comedian Rodney Dangerfield have a lot in common. They both can tout, “I don’t get no respect!” Most people do not realize how pivotal the HVAC air filter is to both their homes and their HVAC systems.

Respect Yourself, and Your Air Filter

Here in South Carolina , you may think about your filter only when the seasons change, particularly transitioning from the warmer temperatures of summer to the cooler temps of fall, but filters need more attention than that all year long. Both our Coastal Air + Refrigeration HVAC professionals and ENERGY STAR ® recommend replacing your filter as frequently as every month , but at the very least every three months. Here’s why.

1. Keeps Your Indoor Air Quality High

The purity of the air you breathe inside your home, your indoor air quality (IAQ) , is not always high. By changing your filter on a monthly basis, you can improve it. Here are a couple worthwhile statistics to know.

According to the National Center for Biotechnology Information (NCBI), Americans now spend as much as 90 percent of their time indoors . And according to the US Environmental Protection Agency (EPA), our indoor air is two to five times as toxic as our outdoor air.

These indoor pollutants cause or can worsen allergies and respiratory illnesses, such as asthma, as well as other long-term conditions and diseases like heart disease and cancer. In other words, keeping the air you breathe in your Conway home as clean as possible should be a priority. Change your HVAC filter monthly to help keep those toxic particles out of your lungs.

2. Increases the Efficiency of Your System

By changing your filter on a regular basis, you can help increase the efficiency of your HVAC system. A dirty filter is a common reason for breakdowns due to overworking furnaces and air conditioners.

With a clogged filter, the air can’t get through, causing the system and its motor to work harder and run longer. When everything has to work harder and longer than designed, it causes system stress and decreases your system’s efficiency. So keep it running smoothly with regular filter changes.

3. Saves You Money

Despite the argument that changing your filter on a monthly basis costs you more money, in actuality, regularly changing your filter can save you money. By giving your HVAC system clean filters, your system does not have to work as hard to heat or cool your Conway home. Less stress on your system’s components extends their life making them less likely to need premature replacement.

4. Leaves a Green Footprint

Being a good steward of Mother Earth and all her resources is more important than ever. When your filter is dirty and causing your system to work harder—since it is stressed—using more energy. These days, HVAC systems are designed to run efficiently, in an eco-friendly manner, so you will be doing your part simply by changing your filter.

5 Reasons to Schedule a Fall Furnace Clean and Check

Mon, 18 Oct 2021 18:54:00 GMT

Once the cooler weather hits here in Myrtle Beach this fall, you are going to want the inside of your home toasty and comfortable. This means turning on your furnace . Long before the first night you’ll want to use it, you should have your furnace cleaned and checked by a professional from Coastal Air + Refrigeration .

You may think this maintenance is unimportant and you can save money by forgoing it, but you would be mistaken. Here are five reasons you should call to schedule your appointment today.

1. It prevents unexpected and costly breakdowns.

When you schedule your furnace clean and check regularly on an annual basis, you are preventing breakdowns. By having one of our seasoned experts inspect and clean your system, he or she can spot any impending repairs or weaknesses. This alerts you so you can take care of the issue in a timely manner, circumventing middle-of-the-night emergencies when emergency services will cost you more.

2. It saves on monthly energy bills.

By having your furnace cleaned regularly, which includes replacing or cleaning your filter , your furnace can work more efficiently, saving you energy. Once it gets dirty, airflow becomes diminished and blocked. This causes your furnace to work harder, using more energy to do the same amount of work it normally does under easier conditions.

3. It keeps you and your family safe.

When your furnace is not inspected and cleaned before you use it every fall, you run the risk of missing a possible unsafe issue or repair. Sometimes something as dangerous as a cracked heat exchanger can occur.

According to the Air Conditioning, Heating & Refrigeration Institute (AHRI) , this can leak toxic carbon monoxide into your South Carolina home’s air, and you may not be aware of it at the beginning stages of the problem. By then, dangerous levels of the poisonous gas could already be in your home. One of our professional and highly trained technicians can spot and address safety issues prior to them becoming unsafe.

4. It extends your furnace’s life span.

Your furnace is meant to run smoothly and efficiently, with an expected life span of 15 to 20 years (for gas furnaces). When you neglect its annual clean and check, the dirt and dust accumulated inside builds up and causes problems.

This in turn forces your system to work harder, wearing down its parts sooner. Keeping things running smoothly helps your furnace live a long and healthy life.

5. It keeps the warranty valid.

Your furnace most likely came with a manufacturer’s warranty. Many of these warranties specify that regular maintenance needs to be performed to keep the system in tip-top shape and to prevent unneeded repairs. By not scheduling these maintenance appointments, your chance of incurring repairs increases and may void your warranty.

Is HVAC Preventative Maintenance Worth It?

Thu, 30 Sep 2021 09:00:00 GMT

At Coastal Air + Refrigeration , we know what an investment your heating , ventilation, and air conditioning (HVAC) system is in your home. That’s why time and time again we recommend regular preventative maintenance on all your HVAC units. You need to invest in your investment.

We have had some of our Carolina Forest area customers ask us if it’s really worth it. Does preventative maintenance pay off or is it a scam?

Our response is always the same—yes, it is definitely worth it. And, no, it is not a scam. In fact, the majority of heating and cooling service calls are a direct result of a lack of proper maintenance.

Maintenance Benefits for You

You can experience many benefits as a direct result of preventative maintenance. When you regularly maintain your system, you will:

Save energy and money – When your heating and cooling system is regularly cleaned and checked, it will operate at its peak performance and most energy efficient. This saves you energy, producing lower energy bills, thereby saving you money as well.
Prevent unnecessary repairs – Since your system is checked on a regular basis, any wear and tear on parts is noted by our professionals and addressed. This reduces the middle-of-the-night breakdowns and accompanying costly repairs. Also, when your system is cleaned regularly, your system runs smoother, avoiding extra stress on your system’s components.
Improve your indoor air quality – Scheduling regular cleanings cuts down on the dirt-and-debris buildup in your system. This means less of this finds its way into your South Carolina home’s airflow and into your lungs. Additionally, changing your filter every few months allows it to do its job and stop any dust and particles from proceeding to the general airflow, giving you high indoor air quality . And, according to ENERGY STAR® , airflow problems can reduce your system’s efficiency by up to 15 percent.
Extend your system’s life span – Ensuring your heating and cooling system is clean and checked allows your system to operate as the manufacturer intended. With few problems and repairs, your system’s life span can increase, once again saving you money from purchasing a new one.
Keep your manufacturer’s and installation company’s warranties valid – Many companies stipulate your warranty is null and void without regular professional maintenance. You may need to provide your maintenance receipts as proof in the case of a warranty claim.
Save time – When you participate with one of our preventative maintenance service plans, you save yourself time. Our professionals contact you to schedule your appointments and then take care of the maintenance for you. This saves you time in your day on both counts.

Listen to Your HVAC System

Fri, 17 Sep 2021 09:00:00 GMT

Think of your heating and cooling (HVAC) system components as the instruments in a quiet symphony.

When all the pieces are in good condition and work in harmony, the only sounds you will hear will be the quiet hum of a motor and whisper of air as it exits registers in your South Carolina home.

An HVAC system operating at peak efficiency is music to the ears.

An HVAC system in need of professional attention produces noise.

Unusual sounds may indicate the need for a tune-up, cleaning, or repair. The experts at Coastal Air + Refrigeration can decipher the noise and get your system back on track. They have the knowledge and experience it takes to keep your HVAC equipment running at peak efficiency and delivering the comfort you expect in your Conway home .

According to ENERGY STAR® , annual energy bills top $2,200 in the average household. Half of that cost goes to heating and cooling systems. Maintaining HVAC equipment is essential to keeping costs down and more money in your pocket.

You can troubleshoot your furnace , air conditioner, heat pump , and ductwork by paying attention to sensory cues. If the equipment emits strange odors or working parts look worn and dirty, it may be time to call for professional help. Listening to your HVAC system is one of the easiest ways to be proactive.

What is your HVAC system trying to tell you?

Here is a guide to some typical sounds:

Screaming — If your air conditioner sounds like the victim in a horror film, it may have a refrigerant leak or too much pressure in its compressor. Turn the system off and call one of our professionals.
Squealing or screeching — These sounds are like the high-pitched noise from worn brakes or metal on metal. They may indicate a worn belt or motor bearing. Sometimes the motor simply needs lubrication. Replacing the belt and lubricating the motor are not for do-it-yourselfers. For fast, quality, and expert service, call the professionals at Coastal Air + Refrigeration .
Rattling — If you notice rattling near an air register, it could mean the grille is loose. A rattling sound from within an air duct usually signals the presence of debris. Did you inadvertently drop a nail through the register or did someone in the family force a tiny toy through the grille? It may be time for a thorough duct cleaning.
Debris inside the outdoor unit of the air conditioning system also can cause rattling. Other possibilities include a loose fan and loose parts in the blower or motor. These also can cause rattling sounds from the outdoor unit of your air conditioning system. The fan could be loose and there might be a problem with the blower or the motor.
Banging or clanking — A loose part that rattles can eventually break or disconnect, causing a banging sound. Your furnace blower also could be unbalanced, or your compressor might be loose.
Scraping — A metal scraping sound likely means a component is broken and possibly moving around in the unit. It might also indicate damaged or obstructed fan blades.
Loud humming or clicking — Humming, clicking, even buzzing usually indicate electrical problems, such as loose wiring, a defective capacitor, or failing thermostat.
Hissing — If you hear hissing from your air conditioning unit, it could be a refrigerant leak or a problem with the compressor motor. If the sound is inside the walls of your home or from the furnace, it likely is a leaky duct. Either way, you will need to call a professional for repairs.

What Questions Should You Ask Before Hiring a Plumber?

Tue, 17 Aug 2021 09:00:00 GMT

Indoor plumbing is one of those things we all take for granted—that is, until we lose that convenience due to a plumbing problem. When plumbing issues inevitably arise, knowing what to do and who to call can drastically reduce the stress and difficulty of the situation. Even if you don’t have a leaky faucet or a clogged drain on your hands at this moment, it’s still a good idea to know what to do if and when such a problem happens.

Our professionals at Coastal Air Plus want to help you to be prepared. Here are some important questions to ask your potential plumber before signing on the dotted line.

May I see your license, and are you insured?

Most states require plumbers to hold licenses, so it’s a good idea to check your local rules regarding licensing before hiring a plumber. Don’t make the mistake of assuming any random plumber has a license, because this can cause a lot of trouble later. In addition, be sure your potential plumber is insured, so you know you’re covered for any accidents or damages.

What training and certifications do your plumbers hold?

Although many plumbers may simply hold a high school diploma and a valid license, others may go above and beyond to obtain professional training and certifications. Depending on the scope of your project, you may want to check to see if your plumber has completed third-party certification courses such as the ones offered by the National Inspection Testing and Certification Corporation (NITC) . Those plumbing businesses that take continuing education seriously will likely have the most experienced plumbers in the industry.

What is the cost of this project?

For most Myrtle Beach homeowners , cost is a significant factor in deciding who to hire for a plumbing job. Of course, you don’t want to spend more than you have to, but it is also unwise to immediately give your job to the lowest bidder.

If a plumber does low-quality work, your costs will inevitably rise if you must hire another plumber to resolve new issues. A good rule of thumb is to obtain three written estimates, so you can compare them and choose the best combination of quality and affordability.

What are payment terms and what forms do you accept?

Particularly for large, expensive plumbing jobs, you’ll want to know how and when your plumber expects to be paid. Being up front and open about this issue will help clarify expectations on both sides.

You may need to set up a payment plan if you are doing a large project, and understanding what payment options your plumber offers will be very helpful. Even with a small project, it’s still prudent to hammer out payment details before work commences. It’s also a good idea to ask what payment forms are accepted, although most plumbers will accept credit cards today.

What are your warranty terms?

Reputable plumbers stand behind their work. Be sure to ask what kind of warranties are offered in terms of equipment, parts, and labor. You’ll be much more confident in a company willing to back its promises. Typically, plumbing work should be guaranteed for at least one year.

How long have you been in business?

Although there are exceptions, plumbers who have been in business longer have served more people and, as a result, have more experience. In general, trust those seasoned companies who have a good reputation in your community.

What do others say?

Ideally, you have a family, friend, or colleague who can provide a recommendation for a South Carolina plumber before you begin your search. However, if you don’t, it’s easy to go online these days and check a plumbing company’s reviews.

See what others have to say, and be on your guard if there is a considerable amount of negative feedback. You can also check third-party organizations such as the local Better Business Bureau, Angie’s List, Google Reviews, or other consumer protection organizations for ratings and suggestions.

Four Factors to Consider When Buying a Heat Pump

Fri, 13 Aug 2021 09:00:00 GMT

So you are looking to invest in a heat pump. You are not alone––many Americans are making the switch.

Why? For starters, heat pumps are generally more efficient than a traditional heating , ventilation , and air conditioning (HVAC) system . What is more, heat pumps offer both heating and cooling, so they are versatile.

At Coastal Air + Refrigeration , we want to help you make the best decision for your Carolina Forest home’s needs. Our aim is for you to be satisfied with your heat pump for years to come.

Here are four questions to ask yourself when picking out a new heat pump:

1. How much do I want to spend up front?

Heat pumps offer you more efficiency . However, many of the more efficient products have a higher up-front cost than a traditional heater or air conditioner (AC). Generally, a good rule of thumb is the more you invest up front, the less you will pay in the long run. It is up to you to decide which heat pump is best for your budget.

2. What type of heat pump do I want?

Air-source and mini split are a couple main types of heat pumps you can consider.

Air-source heat pumps transfer heat from the outdoor air to warm your South Carolina home in the winter and expel heat from your home during the summer. This type of heat pump is so efficient, the US Department of Energy (DOE) asserts an “air-source heat pump can deliver one-and-a-half to three times more heat energy to a home than the electrical energy it consumes.”

Mini splits (also known as ductless units) also use air source technology, but they offer true zoning with a variety of different configurations for the indoor units. They are extremely efficient and a great option for homes with existing ductwork .

Each type has its advantages and disadvantages, and we are happy to help you sort through them all. Call to speak with one of our experts to discuss these options further.

3. Will I need a dual-fuel system?

Our source heat pumps can’t operate efficiently when outdoor temperatures become colder. This is why homeowners in colder regions of the country might need a dual-fuel system.

A dual-fuel system is a heat pump supplemented with a different heating appliance. When temperatures are too low for your heat pump to operate efficiently, your alternate heat source, such as a furnace will kick on.

Talk to one of our Coastal Air + Refrigeration HVAC professionals to determine if this is a good choice for your home.

4. What type of thermostat should I buy?

In addition to your heat pump, our highly trained and experienced experts can install new controls for heating and cooling your home. Based on your Carolina Forest home needs, you can choose between a variety of thermostats with features to fit your comfort needs.

Standard thermostats have a simple, familiar interface. They provide you with a Heat or Cool option and On or Auto fan control. Programmable thermostats can be set to automatically change the temperature setting during certain hours of the day, such as when you are not at home or while you are sleeping, in order to save energy. Wi-Fi thermostats can be controlled remotely using your smartphone, whether you are home or away. Depending on the model, your Wi-Fi thermostat may offer energy-usage analytics so you can readily and easily monitor your energy consumption.

3 Health Benefits for Using Your AC While Sleeping

Fri, 30 Jul 2021 09:00:00 GMT

A major part of your health relies on getting a good night’s sleep. That’s why it’s not just important to run your air conditioner during the hot summer days. You also need to keep your home comfortably cool at night as well.

At Coastal Air + Refrigeration , we understand that depending on your air conditioner to run efficiently is crucial to helping you get the good night’s sleep you deserve. We also know how critical sleep is to everyday life, so we make it a priority to provide our customers in the Conway, SC , area a cooling system that ensures the utmost comfort all hours of the day or night.

Getting It Right

According to a study published in the National Centre for Biotechnology Information (NCBI), part of the US National Library of Medicine (NLM) , it’s recommended to set your thermostat between 60 and 68 degrees Fahrenheit at night for a comfortable full night’s sleep. By comfortable, we mean not constantly waking up to add blankets or to turn down the thermostat in the middle of the night. Additionally, your body will not have to worry about regulating its own temperature, because your room will already be set to the ideal sleeping condition to do that for you.

Keeping It Right

By keeping your air conditioner in tip-top shape all year long, you can help prevent any potential problems that can arise during the times when you need your cooling system most. That means scheduling regular maintenance for one of our professionals to come out and thoroughly clean your unit of any debris, dust, or dirt, and confirm there are not any leaks or cracks.

The Right Benefits

Once you know your system is working in prime condition, here are three health benefits you can experience from lowering your thermostat’s temperature at night:

1. Helps your mood

It’s not just your physical health that will improve—your mental health will significantly change as well. Getting uninterrupted sleep is essential for staying alert, energetic, and keeping a positive outlook on life. The less signs of irritability and exhaustion you show, the more likely you will be able to function at your best.

2. Fights aging

Resting comfortably and staying cool are not the only advantages of lowering your home’s temperature before going to bed each night. While sleeping, your body is also more likely to release melatonin, a hormone that fights symptoms of aging and helps prevent getting wrinkles sooner than you should.

3. Contributes to weight loss

It’s not just a nutritious diet and getting regular exercise that are the necessary components to losing weight. You also need a healthy sleeping pattern to help shed those unwanted pounds. Without a comfortable and proper sleep schedule, your weight-loss plan will not be as effective and ultimately can increase your odds of losing muscle mass instead of fat.

How to Properly Size an AC System

Thu, 15 Jul 2021 09:00:00 GMT

In the heat of the summer, it’s easy to assume that bigger is better when it comes to air conditioning (AC) systems. Obviously, if you have an air conditioner that’s too small in your Myrtle Beach home, you will not be able to keep your temperatures consistently low even if the unit is running constantly.

However, if your air conditioner is too large for your home, it will quickly cool down the space and shut off. Once the temperature rises, it will kick back on again. This constant on and off cycling, referred to as short cycling, uses a great deal of energy and wears down your air conditioning system more quickly.

Air conditioner loads must be calculated carefully, so you can match the unit to your cooling needs. Our professionals at Coastal Air + Refrigeration would be happy to help you select the best-sized air conditioner for your particular South Carolina home. In the meantime, here is a peak into how our trained experts calculate air conditioning needs.

Definition of Terms

In order to understand how to size an air conditioning unit, you have to know a little bit about how capacity is measured. Air conditioning systems are measured by tons, which specifies how much a particular unit can cool. For example, a one ton air conditioner can generate 12,000 BTUs.

A BTU is a British Thermal Unit, and one BTU is the energy needed to cool one pound of water by 1 degree Fahrenheit every hour.

Air Conditioner Sizes

The smallest air conditioner is 1.5 tons or 18,000 BTUs and they can increase in size up to 5 tons or 60,000 BTUs by increments of one-half ton or 6,000 BTUs.

For a rough calculation to select an air conditioner for your home, you can take your total square footage, multiply it by 25, divide it by 12,000, and subtract .5.

Of course, our Coastal Air + Refrigeration heating, ventilation , and air conditioning (HVAC) professionals use the complex Manual J load calculation to properly size HVAC systems. This rough calculation cited here will only provide a ballpark figure that should never be used to purchase a system on its own. There are other important elements that factor in to the calculations.

Other Important Factors

Before ordering that new air conditioner based on the simple math equation, you need to realize there are many other factors that should be considered before making a final decision:

Ceiling height – Not all homes have standard ceiling heights. If you have a vaulted ceiling, loft area, or open floor plan, you may need to calculate the volume of your home, not only the square footage. High ceilings will require a larger air conditioner.
House style – Two homes that have the same square footage may require different-sized air conditioning systems. A single-story sprawling ranch home requires more cooling power than a three-story townhouse.
Local climate – If your home is located in a hot, humid location, you will need a different-sized air conditioner than if you live in a milder, dry climate. Temperature and humidity play a significant role in how much cooling and dehumidifying you will need your air conditioner to do.
Size, type, and number of windows – Windows tend to leak energy out of your home more easily than solid walls. You must take into consideration the size and number of windows as well as how well they are sealed and their energy ratings.
Insulation – In a similar way, a better insulated home requires less cooling energy than a poorly insulated one. If you are building or doing a major remodel, it may be a good decision to increase insulation before selecting your new air conditioning system.
Other factors – Even considerations like the existing ductwork , type of window coverings, and number of residents and how often they are home can affect the load requirements of your air conditioner.

Heat Pump or Air Conditioner: What You Need to Know

Wed, 30 Jun 2021 09:23:00 GMT

Think of an air conditioner and a heat pump as twins.

Both can cool your South Carolina home by moving heat to the outdoors. Both use the same cooling fundamentals and components as refrigerators. Both employ refrigerants, coils, and fans to create a comfortable environment indoors when temperatures rise outside.

The big difference between the two systems is versatility. Heat pumps have it. Air conditioners do not.

An air conditioner is just one part of a heating, ventilation, and cooling (HVAC) system that can bring comfort to your Carolina Forest home year-round. It provides cool air in the summer and a heating unit such as a furnace keeps your home warm and toasty in winter. Two separate kinds of equipment fulfill two different needs.

On the other hand, a heat pump does it all. Despite its name, a heat pump is an air conditioning system that can work in reverse to heat your home. It fulfills two different needs with just one unit.

Which is better for you? It depends on the size of your home, winter climate in your region, and your budget. Does your home contain a furnace and ductwork ? You may simply want to add an air conditioner. Is your furnace nearing the end of its service life and you plan to replace it soon? Your next purchase might be a heat pump.

The professionals at Coastal Air + Refrigeration can make that choice easier by recommending a system that delivers the comfort level you want at a price you can afford. Our experts install, repair, and maintain both central air conditioners and heat pumps.

Keeping Cool with a Heat Pump or Air Conditioner

If air conditioning is at the top of your “must-have” list, you are not alone. According to the US Energy Information Administration (EIA), nearly 90 percent of US homes use some kind of air conditioning equipment .

Air conditioners and heat pumps cool air by transferring heat. If you understand how one system works you will understand both.

An air conditioner, for example, has an outdoor unit that contains a condenser coil, a compressor, and a fan. Indoor components consist of an evaporator coil and fan. Tubing connects the coils and conveys refrigerant between the indoor and outdoor components.

The indoor fan blows air over the cold refrigerant-filled evaporator coils and through ducts into each room of your home. At the same time, the liquid refrigerant absorbs heat from the air and changes to a gas that moves outdoors to the compressor, where pressure turns it back into a liquid. Condenser coils and a fan inside the outdoor unit remove the heat created by the compression process. The cooled liquid refrigerant heads to the indoor unit to begin the cooling cycle again.

The most common kind of heat pump, an air-source heat pump, runs on electricity and transfers heat through air. It works best in mild climates and requires a back-up heating source, such as a furnace, when the outside temperature dips below 30 to 40 degrees Fahrenheit.

Geothermal or ground-source heat pumps transfer heat from the earth or an underground water source. The DOE estimates that geothermal heat pumps can lower energy use by 30 to 60 percent. However, they are considerably more expensive.

Which System is Right for You?

Consider these factors:

Climate — If you live in a region of the country where winters are mild, a heat pump is a highly efficient way to cool and heat your home. Look for equipment with a SEER (Seasonal Energy Efficiency Rating) number higher than the minimum federal standard of 14 for cooling efficiency that will pay off in lower energy costs. If you install a heat pump in a locale where temperatures dip below freezing, you will need a secondary source of heat, such as a furnace. Air-source heat pumps work harder – losing efficiency – in extremely cold and hot temperatures. A furnace can keep your home warm on extremely cold days until the temperature rises enough for the heat pump to kick in.

Central air conditioning works in any part of the country but is an especially good choice in the Midwest and Northeast, where it is paired with a furnace. Look for a SEER rating of 15 or higher.

Cost — The price tag depends on size, brand, quality, and other factors. You generally will pay more for a heat pump but will likely have lower utility bills. Although central air conditioning is less expensive, it can only cool your home. You need a furnace to provide heat.

Common AC Problems and Solutions

Fri, 28 May 2021 09:00:00 GMT

When the weather gets really hot in Myrtle Beach , the last thing you want is a broken air conditioner. Many common problems with air conditioning systems can arise. Our team at Coastal Air + Refrigeration wants you to be aware, prepared, and ready to solve these air conditioning issues so you and your family can stay cool this summer.

Inconsistent Cooling

Do you find some of your rooms are too cold while others are still on the warm side? Many South Carolina homeowners have trouble with inconsistent cooling. While factors such as the age and design of your home can cause these consistency issues, you may also have a leak in your duct system. One of our trained professionals can come and inspect your air conditioner and duct system and suggest solutions to this problem.

Failure to Cool

If your air conditioner is simply blowing warm air, you may want to check simple things like your filter . Dirty filters can prevent your system from functioning properly and are easy to change. They can also decrease the efficiency of your system.

In fact, you can save between 20 and 50 percent of the energy used for your air conditioning by changing your filter in combination with other energy-saving actions .

In some cases, you may need to clean condenser coils or have one of our professionals come out and add refrigerant to your air conditioner due to a leak in your system. Other mechanical failures may cause cooling issues as well.

One way to ensure your air conditioner is ready for the season is to have regular maintenance performed. One of our highly trained and experienced professionals can conduct a thorough inspection, cleaning, and tune-up to be sure all system components are running well.

No Air Movement

When you place your hand on a room’s register and feel no air blowing at all, even though your air conditioning unit is turned on, you may have a broken fan or thermostat , or a tripped breaker.

It’s easy to fix your tripped breaker on your own, and you can inspect your unit to see if you notice the fan is running or not. Other less common issues may be a bad blower belt or wiring issues, which may require a professional.

Ice Accumulation

You may notice that ice is accumulating around your air conditioning unit at times. Many situations can result in your air conditioner freezing up. Check to be sure you have good airflow through and around your air conditioning system.

Dirty air filters, closed dampers, or blocked vents or ducts can restrict airflow. If all of these areas seem clear on visual inspection, you may want to call our trained team to conduct a more professional check of your system.

Strange Noises

By being aware of what your air conditioning system usually sounds like, you will notice more quickly if something seems amiss. If you hear strange noises, they can be cues something needs to be repaired or replaced.

Squeaking sounds usually indicate problems with your air conditioner belt, which may need realignment or replacement. If you hear grinding sounds, you may need to inspect the motor’s bearings. Other noises may be easier to remedy, such as rattling can simply indicate a loose cover.

Odd Operation Patterns

In nearly all weather conditions, your air conditioner should kick on at a certain temperature, run for a while, and then shut off. If you find your air conditioner is constantly running or seems to cycle on and off too frequently, you need to address these issues.

If your air conditioner never takes a break, you may have an issue with the fan, refrigerant level, or relay switches. This may require a professional visit from a member of our team to diagnose and repair th ese issues.

A system that constantly turns off and on may indicate a dirty or blocked condenser unit or evaporator. A thorough cleaning can help solve this issue.

Air Filters vs. Air Cleaners

Fri, 30 Apr 2021 09:00:00 GMT

Our highly climate-controlled indoor environments can often be extremely comfortable in our modern world. Combine that with the fact so many of our daily needs are easily met without needing to go outside, and you find a society that spends nearly all its time indoors. As a result, poor indoor air quality has become a significant area of concern as a contributor to potential health problems.

Our team at Coastal Air + Refrigeration , along with many manufacturers of air filtration and air purification products, are working to provide tools to help you ensure clean indoor air for you and your family. Here are some details about currently available solutions.

Air Filters

Air filters are typically a part of your Conway home’s heating, ventilation, and air conditioning (HVAC) system . Before circulating air enters your furnace or air conditioner to be heated or cooled, it passes through a filter to trap and remove a wide range of particulates.

Many different types of air filters are available, ranging from very basic and inexpensive to more costly versions that filter out microscopic particles.

An industry-wide rating system promoted by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) helps consumers compare one type of filter to another in terms of performance. A minimum efficiency reporting value (MERV) rating system measures a filter’s ability to remove particles from the air. Filters carry a rating somewhere between 1 and 16, with the higher values signaling finer filtration.

Air filters can be made of many different types of materials. You may have used a layered fiberglass filter that’s surrounded by a metal grate or a pleated polyester filter in a cardboard frame. These filters typically need to be replaced every one to three months.

Homeowners living in South Carolina who have family members with allergies, asthma, or other respiratory illnesses may want to consider using a high efficiency particulate air (HEPA) filter. These filters capture 99.97 percent of all particles 0.3 microns or larger. The National Air Filtration Association (NAFA) specifies six different levels of HEPA filters.

Air Cleaners

Air cleaners are often used in conjunction with HVAC-related air filters. These are usually separate appliances typically designed for a single room or a certain square footage of space. A wide variety of different technologies and systems are available, and each one usually focuses on a particular set of particles.

For example, home ultraviolet (UV) air cleaners were developed from purifiers used in hospitals for disinfecting the air. These tackle bacteria, viruses, mold, and other pathogens. On the other hand, activated carbon filters are very effective in removing gasses, odors, smoke, and other particles.

HEPA air purifiers work in a similar way to HEPA filters and remove dust, pet dander, pollen, and mold spores from your indoor air. Although HEPA air purifiers are effective at filtering out very small particles, they are unable to remove bacteria and viruses.

Another type of air purification technology is using ions. These purifiers emit negative ions into your living space, which attract positive ions like dust. The resulting particles become heavier and land on your home’s flooring or other surfaces to be collected during vacuuming and dusting chores. Remember to use a HEPA vacuum bag to maximize the capturing of the resulting particles.

Although all of these air purification systems typically work in a single area or confined space, you can invest in house-wide purification systems as well. For instance, electronic air cleaners work with your HVAC system by employing static electricity, HEPA filters, and ionic cleaners in a single system. Centralized air cleaners can be installed as part of your ductwork and can complement your HVAC filtration system , and air-to-air exchange systems will allow you to pull in more fresh air from outside.

Is It Normal for My AC to Turn On and Off?

Fri, 16 Apr 2021 09:00:00 GMT

When an air conditioner (AC) turns on and off in rather quick successions, without running for longer periods, this is called short cycling . It’s fairly common, but when this happens it means there’s something wrong with your air conditioner. So what should you do?

Don’t leave these occurrences alone. They will increase your energy costs, usually indicate a larger problem, and could lead to permanent damage of your unit, thus requiring a costly replacement. Short cycling also shortens your air conditioner’s life span.

Have one of our professional technicians inspect your heating, ventilation , and air conditioning (HVAC) system as soon as possible. Any one of our experts at Coastal Air + Refrigeration can diagnose and repair this issue for you. Don’t delay, so we can get your air conditioner back to its most efficient state for you.

While there are many possible reasons for short cycling, here are several of the most common ones and what can be done to fix them.

Low Refrigerant

The coolant that flows through your system, helping to absorb heat and cool the air inside your home, is called refrigerant. You may know it by one of its brand names—Freon®. When your refrigerant is low, the needed compressor-pressure levels are affected. This triggers your compressor’s low-pressure control, shutting off your compressor.

When the pressure rises and triggers your air conditioner to restart, this causes the short cycling. If your refrigerant level is low, this indicates your air conditioner has a leak, as refrigerant is cycled throughout the compressor, not burned off.

Low refrigerant can also cause frozen coils. One of our professionals can find your leak and prevent any further issues or damage.

While our professional is looking at your refrigerant, be sure to have a conversation about the type of refrigerant used in your air conditioner. To be consistent with the 1987 Montreal Protocol, the US Environmental Protection Agency (EPA) has mandated regulated changes to all HVAC refrigerant here in South Carolina and across the United States. Your air conditioner may be affected. If it is, you will have some decisions to make.

Thermostat Location

Your thermostat acts as the sensor for your air conditioner, telling it when to cool your home. If its location is not optimal, such as near a window or too close to a vent, your thermostat will be sending misleading information to your air conditioning system.

Suppose your thermostat is in the direct line of a vent’s airflow. This will cause the thermostat to think it’s cooler in your home than it really is, and your air conditioner will shut off thinking it’s reached its desired temperature. Since the cool air is no longer flowing through the vent, the thermostat realizes your home is actually still too warm and triggers your air conditioner to start up again. This is short cycling. Be sure your thermostat is located in a central location away from direct sunlight and vents.

Dirty Air Filter

Dirty air filters are one of the most common and easily remedied problems with air conditioners we see here in Myrtle Beach . The dirty filters restrict airflow, which in turn causes so many problems, one of them being a frozen coil. This can cause your air conditioner to malfunction and short cycle. Be sure to change your filters regularly to avoid any issues.

Oversized Air Conditioner

An air conditioning unit that’s too large for your home short cycles, because it cools your home too rapidly while it doesn’t dehumidify it properly. So it will shut down and start up frequently.

You will more than likely also find your home has hot and cold spots, and you will experience higher energy bills. If your air conditioner is newly installed, talk to the technicians who installed it to see what they can do to help you.

You want to be sure a Manual J heat load calculation (an Air Conditioner Contractors of America [ACCA] approved method of calculating house cooling loads) is always performed when determining the proper size heating and cooling system for your Myrtle Beach, SC , home. Call our qualified professionals to do a Manual J at your home to determine if your current unit is appropriately sized.

How UV Lights Benefit Your HVAC System

Tue, 30 Mar 2021 09:00:00 GMT

Adding an ultraviolet (UV) lighting system to the heating , ventilation , and air conditioning (HVAC) equipment of your South Carolina home or business creates a healthier environment for you and your loved ones.

At Coastal Air + Refrigeration , we take great pride in providing reliable information about the latest trends, products, and services in the HVAC industry. You can trust our certified team of professionals to offer you sustainable solutions that will add another layer of comfort, safety, and health to your Carolina Forest home or business. We listen, and we care.

How Do UV Lights Work?

A UV lighting system destroys microorganisms by altering their DNA. These systems kill microbes—they do not remove inorganic particles such as dust or pet dander. There are two types of HVAC UV lights: coil sterilization and air sterilization. Both systems easily integrate with the air ducts of your Carolina Forest home or business.

Coil UV lights sterilize the air handler coil of your air conditioning unit. Because the indoor coil condenses moisture from the air to help dehumidify your home, it is a prime breeding spot for mold and bacteria. A coil UV light runs 24/7 to shine directly on the indoor coil of your air conditioner.

Air sterilization lights sterilize the moving air in your ductwork. This system cycles on with the air handler blower to kill airborne germs and mold. These systems operate more effectively when combined with a quality air filter that has a high MERV (Minimum Efficiency Reporting Value) rating. Our HVAC professionals at Coastal Air + Refrigeration can help you choose the right filter for your particular system.

Can UV Lights Kill Viruses?

UV lighting systems have a proven track record of attacking mold, bacteria, viruses, and other pathogens in the airflow. According to the Centers for Disease Control and Prevention (CDC), UV lighting is extremely effective in decontaminating exposed surfaces in hospitals, industrial facilities, and other settings.

While UV lighting systems can improve your indoor air quality and eliminate triggers that cause asthma and other breathing issues, they will not prevent you from getting infected. Common sense and good hygiene are always your best weapons for staying healthy.

Benefits of HVAC UV Lights

These systems improve your indoor air quality by cleaning the airflow that travels through your ductwork . Allowing our professionals to clean and seal your ductwork ensures you get the most benefit from your UV lighting. Another tip to get the best performance from your HVAC system is to regularly change your air filter.

For decades, hospitals and clinics have used UV lights to keep the air and building surfaces clean and disinfected—you can now bring that same cleansing power to your home. And because UV lights function on wavelength, they don’t circulate aerosols that release ozone in your home.

AC Maintenance Checklist

Mon, 15 Mar 2021 09:00:00 GMT

Can you imagine a hot Conway summer without air conditioning? Your air conditioning system can be your very best friend on the warmest days.

Be sure you take the time to perform basic maintenance regularly as well as invest in a professional checkup at least once a year. According to the US Department of Energy (DOE) , good maintenance can save you money and reduce your energy usage.

Here’s a comprehensive air conditioning maintenance checklist, courtesy of our professionals at Coastal Air + Refrigeration , to help keep your system in excellent working order.

Check Air Circulation

Perhaps the most important thing to be sure you have around your air conditioner is plenty of space for good air circulation. Most air conditioners have a unit that sits outside your home.

It’s a good idea to inspect this area to be sure leaves, sticks, and other yard debris are cleared every spring. However, once the summer gets into full swing, don’t forget to mow and weed wack around your unit as well.

Change Filters

Being sure you regularly change your filters accomplishes the same goal of ensuring good air circulation. If you have a clogged filter, it can take your air conditioning system more effort to move the air throughout the unit, wearing down parts prematurely. Pay attention to the recommended life of your filters and change them on time.

Uses Your Senses

General awareness of how your air conditioning system should sound and look can be a simple thing for you to have. If you notice something doesn’t look quite right or your air conditioner is suddenly making unusual sounds or emitting strange odors, it can signal a need for air conditioning repair or maintenance.

Check Coolant Levels

Although the first three items on the checklist are easy for just about any South Carolina homeowner to do, the remainder of these items may take a bit more experience. If you are uncomfortable with any of these additional maintenance tasks, be sure to call in one of our professionals to help.

The refrigerant or coolant must be at a specific level and pressure to keep your air conditioning system running efficiently. You’ll want to periodically check this level, and if your coolant is low, you’ll need to call in one of our professionals to refill your system. In addition, leaking coolant can be a significant problem for the environment, so address any noticeable leaks immediately.

Look for Ice Buildup

If you notice your air conditioning evaporator coil has ice building up on it, you probably have an air-circulation problem. Double check to be sure your filter and ductwork are clean.

If you have a great deal of ice, you may need to shut off your system, defrost all of it, ensure air circulation is fine, and then turn it back on. If the problem continues, it’s a good idea to call one of our professionals to conduct an inspection.

Inspect Connections

Be sure all the electrical connections as well as ductwork and other tubing within the system look tight and secure. Again, this may take experience to understand what a solid system should look like, and you may want to rely on a professional inspection once a year.

Most heating , ventilation , and air conditioning (HVAC) companies will provide a comprehensive service of cleaning and inspection for a reasonable fee. Relying on certified, trained technicians can be an excellent investment in your air conditioning system. Call our Coastal Air + Refrigeration team with any questions you may have.

Check Thermostat

A thermostat is a bit of a tangential part of an air conditioning system, but it’s an important one. If your thermostat is not working properly, it will not be sending the correct information to your air conditioner.

As a result, your system can’t work properly. In addition, if a broken thermostat causes your system to cycle on and off too frequently, it can cause longer-term damage to your entire air conditioning system.

What Accessories Can Help With My Indoor Air Quality?

Fri, 26 Feb 2021 10:00:00 GMT

In modern society, average adults spend nearly all their time indoors at work or at home. In fact the US Environmental Protection Agency (EPA) reports this amount of time reaches upwards of 90 percent for most people. That puts the importance of good indoor air quality at a whole new level.

Our Coastal Air + Refrigeration team wants to give you a comprehensive list of the different indoor air quality accessories available today. Investing in one or more of these technologies and tools will help you and your family breathe a little easier.

Humidifiers

Stand-alone or whole-house humidifiers can be particularly helpful in South Carolina winters when the air is cold and dry. Bringing relative humidity levels back up to an ideal of about 45 percent means less static electricity, dry skin, and scratchy throats. In addition, humidifiers can help protect your wood floors, furniture, and musical instruments from warping, shrinking, and other damage.

Dehumidifiers

Fast-forward to summer, and you may find you have the opposite humidity problem in Myrtle Beach . Summers can feel even hotter when humidity levels are higher. A well-maintained air conditioning system can help ensure some moisture is taken out of the air along with the heat.

However, some homeowners may want to invest in a whole-house dehumidifier or a stand-alone unit for space like a basement. Too much moisture in the air can make cooling down harder, contribute to mold and other allergen growth, and cause condensation or moisture damage to the structure of your home.

Air Filters

All heating, ventilation, or air conditioning (HVAC) systems require an air filter to catch large particles before your indoor air enters your furnace or air conditioning system. Filters range in quality and price, with the most inexpensive filters trapping only large particles and high-efficiency particulate air (HEPA) filters catching some of the smallest.

It’s important to change your air filter regularly, at least every three to six months or according to the manufacturer’s instructions, to keep your air cleaner and your equipment working efficiently.

UV Air Treatment Systems

Ultraviolet (UV) lights have traditionally been used in hospitals and other health care facilities to kill bacteria, viruses, and other pathogens. Today homeowners can piggyback on this technology by investing in UV home air treatment systems to do the same. Air is forced through a UV purifier, which uses shortwave UV light to kill mold, bacteria, viruses, and other pathogens.

HEPA Air Purifiers and Filters

Air purifiers , as well as air filters with the HEPA designation, remove 99.7 percent of all particles that measure greater than 0.2 microns. This includes household dust, pet dander, mold spores, pollen, and many other airborne particles. It’s important to change HEPA filters regularly. When you combine HEPA filters with HEPA purifiers and HEPA vacuum bags, you will make a big improvement in your indoor air.

Activated Carbon

Activated carbon purifiers are perfect for removing odors, gases, smoke, chemicals, and other fumes from the air. Many of these work in combination with a HEPA purifier to tackle most indoor air pollutants. Add in a UV purifier, and you’ll be successfully managing nearly all of the most common indoor air issues in your home.

Ionic Air Purifiers

Able to remove just about anything except smoke and odors, ionic air purifiers are another option to improve indoor air. Earlier models of these systems simply emitted negative ions that bonded with positively charged common indoor air pollutants. These particles grew heavy and fell onto floors and surfaces to be cleaned through dusting and vacuuming. However, the most advanced ionic air purifiers can now clean themselves.

Electronic Air Cleaners

Attached to your HVAC system, electronic air cleaners are a whole-house solution. These use static electricity, a HEPA filter, and an ionic system to trap or kill up to 99.98 percent of all allergens. Essentially, these cleaners combine the best of all available indoor air purification technologies to do a nearly complete job.

Air-to-Air Exchangers

These systems are designed to bring in and treat outdoor air while pushing out the stale indoor air from your home. These exchangers will adjust the temperature and humidity of outdoor air before circulating it through your air duct system.

Air Scrubbers

A relatively new technology, air scrubbing systems work with your HVAC system. Air is forced through a titanium dioxide-coated component and is treated with a UV light. In addition, the scrubbing system transforms contaminants into oxidizers, which can eliminate more pathogens in the surrounding air and even on surfaces. Gases, vapors, odors, volatile organic compounds (VOCs), mold, viruses, and bacteria are among the substances eliminated.

How to Eliminate Dust in My Home

Fri, 12 Feb 2021 10:00:00 GMT

Everyone has it, and nobody wants it. Dust.

It’s rampant everywhere around the country and has become the subject of a lighthearted, frequently repeated myth at both the US Environmental Protection Agency (EPA) and the US Department of Agriculture (USDA). Officials at these agencies understand farming does not occur without creating dust. So the EPA and USDA “have never proposed tightening rules on farm dust. And they have told Congress and the American people that they won’t propose stricter standards.”

Regular Maintenance Will Help

In reality, dust is definitely no laughing matter, no matter the setting. It’s easy to see how it can affect the indoor air quality (IAQ) of your Carolina Forest home, leading to allergens. At Coastal Air + Refrigeration , we know how important clean indoor air quality is for your home.

With indoor air quality typically being dirtier than your outdoor air, you need to take measures to reduce factors contributing to the indoor pollution––both for your health and the health of your home.

Keep in mind, completely eliminating or eradicating dust from your home is an impossible task. By the mere fact it’s virtually everywhere in South Carolina , you can understand why it will always exist in your home. However, you can greatly reduce household dust levels by following some of the recommendations below.

Take Good Care of Your Air Filter

The purpose of the air filter for your heating , ventilation, and air conditioning (HVAC) setup is to trap dust and debris flowing through the unit’s air. Air in your home is vented through your HVAC system and forced through its filter. Using the best filter you can afford and recommended by your system’s manufacturer can trap a lot of the dust traveling through the air.

Be Sure to Check Your Air Ducts

It can be worse if your air ducts are filthy. Air passing through the ducts will pick up additional dust and dirt, depositing them throughout your home.

If you notice a continuous high level of dust in your home, call in one of our indoor air quality professionals to check the seals on your ducts and to inspect for leaks. Also seriously consider getting your ducts cleaned, especially if you have never done so in the past.

Clean Your Home Regularly

In addition to the numerous HVAC steps you can take to reduce dust, there are some things you can do while cleaning your house to help:

Eliminate clutter, as it collects dust.
Vacuum one to two times a week, using a vacuum with a high-efficiency particulate air (HEPA) filter if possible.
Dust with a microfiber or damp cloth, starting the cleaning motion from top to bottom.
Wash bedding routinely––sheets and pillowcases once a week; blankets, duvets, and pillows every three to four weeks.
Avoid wall-to-wall carpeting, because it can be an ideal habitat for dust and dust mites.

Keep a Constant Tab on Your Humidity

Get Yourself an Air Purifier

Though diminishing or eliminating the sources of your home’s dust is best, utilizing an air purifier can help. A whole-home air purifier works with your HVAC system to purify the air, ridding it of dust and other particles and allergens––the dust never makes it to your home’s living spaces.

A major benefit of a whole-home purifier, compared with small portable units, is it purifies all the air in your home at once. Portable units typically can only purify the air in one room. You would need a separate purifier in every room to achieve a similar result.

What Is Short Cycling?

Fri, 29 Jan 2021 10:00:00 GMT

Short cycling is a term used in the heating, ventilation , and air conditioning (HVAC) world to explain a situation where a furnace or air conditioner turns on and off too frequently. The “short cycle” is the period of time that your HVAC equipment is actually running, and the shorter this cycle, the harder your system needs to work.

Our team at Coastal Air + Refrigeration wants you to understand the concept of short cycling, why it can be harmful and costly, what causes the problem, and what you can do about it.

Root Causes of Short Cycling

If you notice your HVAC system is kicking on and off more than normal, you may be facing a short-cycling issue in your Conway home. Before short cycling causes expensive damage, you’ll want to get to the root cause of the problem. Here are some common causes of short cycling:

Incorrect unit size

If you have a furnace or air conditioner that is too large for your South Carolina home, it will short cycle. Essentially, an oversized furnace or air conditioner repeats the cycle of heating or cooling an area quickly and then shutting down immediately over and over again. According to ENERGY STAR® , ensuring you have the correct-sized air conditioning system can minimize this problem as well as reduce your energy bills.

Repair issue

If you recently had a bad storm that resulted in a power outage, this could cause short cycling. In addition, breaker problems, condensate switch issues, a corroded flame sensor, or objects stuck in your vents could also be a root cause. Contact our professional team to inspect your system to help you identify the cause.

Maintenance issues

Homeowners who fail to regularly maintain their HVAC systems may cause short-cycling issues to arise. For example, a dirty air filter can restrict airflow, which may lead to short cycles. Regular cleaning and inspections can go a long way to prevent short cycling.

Thermostat problems

If you’ve recently installed a new thermostat, be sure it’s in a location where you can get an accurate temperature reading. For instance, thermostats that are in direct sunlight or near heat-generating appliances or vents may misread your home’s actual temperature and signal your HVAC system to turn on and off incorrectly. A broken thermostat could also be the root cause of the problem.

Before You Notice

Today’s technology does have some built-in protection against HVAC short cycling. Similar to an overload trigger on an electrical motor, shut-off controls will often prevent catastrophic HVAC equipment failure. For instance, if temperatures or pressures exceed maximum preset ranges, these safety devices will kick in and shut down your HVAC system for a certain amount of time.

Whether you notice short cycling or your HVAC system shuts down due to this issue, it’s important to resolve the root causes for the long-term health of your heating and cooling system. Living with a system that short cycles can lead to poor temperature-, ventilation-, and humidity-management; a strain on electrical and lubrication systems; and energy wastage.

What You Can Do

The most important thing you can do to prevent short cycling is to regularly maintain your HVAC system with biannual inspections and cleanings. During this process, a trained technician can spot potential problems and correct them before you experience short-cycling problems.

You can also invest in technologies such as variable capacity furnaces and air conditioners , which will adjust the output of your equipment instead of simply shutting down. Look into dead-band settings on your thermostats as well. These allow you to specify an acceptable temperature band so your HVAC equipment cycles less frequently.

Why Is My Furnace Blowing Cold Air?

Fri, 15 Jan 2021 10:00:00 GMT

Did you finally turn your furnace on this winter only to have cold air blowing out of your vents? Or did your furnace stop working just when you started to need it most? There are a few reasons your furnace may be blowing cold air, and there a few things to check before you need to worry too much.

At Coastal Air + Refrigeration , we are here in Conway to help keep your home warm and comfy this winter. If you’re having problems with your furnace, check these things first and then call us for help.

Check Your Thermostat’s Settings

Be sure your thermostat is set on the correct setting . If it is set to ON , the blower will run continuously even when the furnace is not heating the air. The air coming through the vents will seem cool because it’s room-temperature air.

Turn your thermostat to AUTO , then the fan will only run when the furnace is heating, and you won’t get tepid or room-temperature air.

Change the Air Filter

A dirty air filter will cause your furnace to overheat. It restricts the airflow in and out of your furnace, which can cause this issue. If it does overheat, the safety control will shut off the burners, causing the fan to blow cool air through the house versus heated air.

Check the Pilot Light

Your furnace may be blowing cold air because the pilot light has gone out. It’s a simple fix; just relight the pilot.

Depending on the age of your system and its model, you may have to manually relight it yourself or you may only need to push a button. Call our Coastal Air + Refrigeration professionals if you’re unsure how to proceed. We are always happy to help.

After relighting it a few times, if the pilot continues to go out, you should contact us to come and take a look. This is indicative of a bigger problem requiring professional help.

Reboot Your System

If you have a modern furnace, you probably have one controlled by a computer. Sometimes there is simply a glitch in the system, and it needs a simple reset—the same way you would restart your computer or smartphone.

If you turn off your furnace for 30 seconds and then turn it back on, it may reset itself and begin functioning correctly. If it doesn’t start working the way it should after you have restarted it, call one of our heating, ventilation , and air conditioning (HVAC) professionals to diagnose and repair the issue expediently for you.

Examine Your Ductwork

The older your ductwork is , the more likely it is to be damaged or leaky. If it is damaged or leaky, air can escape before it gets to the desired living areas in your South Carolina home. The US Department of Energy (DOE) advises that leaking heated air into unheated spaces, like an attic or basement, can add hundreds of dollars a year to your energy bills.

Be sure to inspect the ductwork yourself, but it is possible you may not be able to visually detect the rips or tears causing your leak. It is best to call us at 843-305-5728 for an in-depth ductwork inspection.

Heat Pump Versus Furnace

Tue, 29 Dec 2020 10:00:00 GMT

Looking to install a new heater in your Conway home? Your two most popular choices are a heat pump and a furnace. Each one has advantages and disadvantages when compared to the other.

The What’s What

Here are some things to consider to help you in your decision-making process. And remember, you can always call one of our heating, ventilation , and air conditioning (HVAC) professionals at Coastal Air + Refrigeration for more clarity on this whole subject.

What About a Heat Pump?

The short version of how a heat pump works is that it transfers heat from inside to outside and then outside to inside. It works on the same philosophy as an air conditioner—it doesn’t create heat, it simply moves it around.

A heat pump is also an air conditioner, so essentially you get a two-for-one system. Here are its pros and cons.

Heat Pump Pros

Runs cleaner. A heat pump runs off electricity, so it’s a cleaner source of energy than gas or oil. It can create one-and-a-half to three times more energy than it uses.
Can be safer. Because a heat pump runs on electricity, there’s no risk of carbon monoxide poisoning or gas explosions.
Can provide both heating and cooling. In other words, it is convenient and could be more cost effective in the right home. Moreover, there are no added components or elements. Just be sure to keep the heat pump well maintained, because the US Department of Energy (DOE) notes how this can result in a 10 to 25 percent difference in energy consumption as compared to a neglected one.

Heat Pump Cons

Is more expensive to run. Since a heat pump operates entirely on electricity, it can possibly cost you more to run—electricity is generally higher in price than gas or oil. Of course, all of this depends on the price of electricity and the efficiency of your heat pump.
Can sometimes only be used for heat in warmer climates. Some heat pump models only heat well in temperatures over 35 to 40 degrees Fahrenheit (making it an ideal choice for the southeastern coastal part of the United States or California). Otherwise, your Conway home will need a supplementary heater , usually a furnace. This is known as a dual-fuel system.
Has a shorter life span. A heat pump has an average projected life span of 12 to 15 years, while a furnace has an average 15 to 20 year life span. A heat pump suffers more wear and tear as well, since it runs year round, as opposed to a furnace that typically runs only a few months a year.

What About a Furnace?

The short version of how a furnace works is that it uses a fossil fuel to create its own heat, and then its fan blows the heat to different areas of your home via ductwork . Here are its pros and cons.

Furnace Pros

Has a longer life span. Running only a few months of the year, a furnace’s life span is greater than a heat pump’s. Most furnaces nowadays can last 15 to 20 years.
Requires less maintenance. Since a furnace is utilized only part of the year, the wear and tear is less, resulting in fewer repairs with proper annual maintenance by a professional—like one of our Coastal Air + Refrigeration HVAC experts .
Can be used in homes everywhere. A furnace can be installed in any climate, regardless of the temperatures, including your South Carolina home.

Furnace Cons

Can’t cool air. Since a furnace can only heat air, unlike a heat pump, you would need to make an additional investment in an air conditioner.
Not as safe. Any time gas or oil involved, there is an inherent safety risk of fire or an explosion, no matter how minimal the risk. And with gas, a carbon monoxide leak is possible.
Not as environmentally friendly to run. Gas and oil don’t burn as efficiently as electricity. The burning produces toxic gases released into the environment.

What It All Comes Down To

As far as which is a better choice, you should take into account several important factors–– such as your Conway area’s climate, the energy rates for electricity and gas, how environmentally friendly the energy source would be––and go from there. If you have more concerns regarding furnaces or heat pumps, don’t hesitate to contact our highly trained and knowledgeable Coastal Air + Refrigeration team.

Improve Your Home’s Indoor Air Quality

Tue, 15 Dec 2020 10:00:00 GMT

Stand outdoors on one of those days when the weather feels perfect, take a few deep breaths, and enjoy the fresh air.

Later, take another deep breath—only inside your South Carolina home . How does it compare?

Improving the indoor air quality (IAQ) at your Conway home or business makes sense on so many levels. Consider your health, your comfort, and your household budget. It’s hard to imagine a more important investment than improving the air you breathe!

At Coastal Air + Refrigeration , we specialize in heating, ventilation, and air conditioning (HVAC) systems that add value to your home and enjoyment to your lives. After all, nothing spells happiness like fresh air.

How Can You Improve Your Indoor Air Quality?

The US Environmental Protection Agency (EPA) consistently ranks indoor air pollution as a growing concern to the public’s health . Fortunately, there are ways to take control of the air you breathe.

A DIY (do it yourself) task you should always remember is to regularly change your furnace air filter . Most manufacturers recommend changing the filter at least every 90 days—more so if you have pets or a smoker in your Conway home. Filters capture dust, debris, and other particles in the airflow. They play a vital role in cleaning the air and helping your HVAC system operate more efficiently.

There are varying types of air filters available, from inexpensive disposal filters to permanent ones requiring regular washing. Consider using high-particulate efficiency air (HEPA) filters if anyone in your home suffers from asthma or allergies. And it’s always a good idea to check manufacturer guidelines on choosing the best filters for your particular system.

The second DIY task is even easier: open the windows in your Conway home for a few minutes per day, weather permitting. You will enjoy the gentle breeze while improving your air quality!

Schedule an HVAC Tune-Up

A well-maintained air conditioner (AC) not only cools down your home but also helps reduce extra moisture in the air.

A leaky air conditioning unit, on the other hand, can cause bacteria and mold growth.

If you want to breathe clean indoor air, keep your HVAC system in good working order. Schedule an annual tune-up for your air conditioning unit in the spring, and one for your furnace in the fall. If you use a heat pump , we recommend tune-ups in the spring and fall since it works twice as hard.

Scheduling tune-ups and inspections with Coastal Air + Refrigeration helps you get the best performance from your HVAC investment. It also nips leaks in the bud and prevents a minor issue from turning into a costly disaster. And remember, upgrading your residential heating and cooling system adds comfort to your life—and value to your home.

Do I Need an Air Filtration System?

Adding a portable or whole-house air filtration system to your home’s HVAC system can do wonders toward improving your indoor air quality. These systems play many roles—certain models are designed to reduce pollen, pet dander, and other inorganic particles. Other systems—particularly ones that use ultraviolet (UV) lighting —help eliminate bacteria, viruses, and other airborne microorganisms.

If you want to eliminate volatile organic compounds (VOCs), pollen, bacteria, and other airborne pollution floating around your South Carolina home, consider installing an air filtration system. While these systems will not prevent you from getting infected, they can significantly improve your air quality. Talk to one of our professionals at Coastal Air + Refrigeration to determine which system best fits your budget and needs.

Maintain Your Air Ducts

Air ducts are like a superhighway delivering fresh air to every room in your home. Industry standards recommend you have your air ducts inspected for cleanliness, cracks, and leaks every two years and you have your ducts cleaned every five to seven years or less. By having your air ducts cleaned regularly, you will help improve the indoor air quality in your home and enhance the efficiency of your HVAC system, which may reduce energy bills.

Tips to Troubleshoot Your Thermostat

Mon, 30 Nov 2020 10:00:00 GMT

If your heating or air conditioning system suddenly stops working in your Conway home, it’s easy to think the worst. However, sometimes the malfunction is not really caused by your heating, ventilation, and air conditioning (HVAC) system at all, but actually from a broken thermostat.

Here are some expert tips on checking your thermostat first as well as some basic troubleshooting ideas from our Coastal Air + Refrigeration team.

The Role of a Thermostat

Whether you have an old-fashioned basic thermostat or a new-fangled smart one in your South Carolina home , the operation of this component is essentially the same. A thermostat is a heat-activated switch that uses an internal temperature sensor to open or close a switch.

This switch completes or disrupts the electrical circuit that runs your heating and cooling system. The thermostat senses the current temperature and activates your furnace or air conditioner to reach the desired temperature.

Check the Obvious First

Although it may seem silly to suggest checking that your thermostat is turned on, the basic things are frequently overlooked. Besides confirming power and that your circuit breakers are operating, be sure you have selected either Heat or Cool , depending on the season. Also, ensure you have fresh, working batteries correctly installed.

If you have a programmable thermostat, confirm your settings are correct and the override function is not engaged.

Basic Cleaning

Over time, dirt and dust can accumulate inside your thermostat and affect its operation. If these or other indoor pollutants clog the thermostat, they can coat the inside and interfere with both electrical and mechanical components.

Carefully open the case, and gently clean with a small paintbrush or a can of electronics air cleaner designed for electronics. If you are uncertain about how to do this correctly, call one of our professionals to avoid damaging the sensitive components.

Consider Location and Balance

It’s important your thermostat is not located in direct sunlight or near a lamp or other electronic equipment. Such a location will inaccurately raise the temperature and cause your thermostat to malfunction. In addition, if your thermostat is not perfectly level, the mercury used in conventional thermostats will not register correctly.

Adjust Anticipator

Your thermostat has a component called an anticipator, which desensitizes your thermostat to slight temperature changes once the room temperature and the set temperature are near each other. Without the anticipator, your HVAC system would tend to cycle on and off too frequently, potentially damaging your equipment.

Usually, the anticipator will operate correctly when it is set between 0.2 and 0.8 amps. However, sometimes you may need to adjust the anticipator. Remove the outside housing and locate a small metal tab that’s near a scale measuring shorter to longer.

If your furnace is kicking on and off too frequently, move your anticipator one calibration mark toward the “longer” setting. On the other hand, if your furnace never brings your home to the desired temperature, move it toward the “shorter” setting by one calibration mark.

After making the adjustment, take note over the next hour or two to see if your problem is resolved before making further adjustments.

Trying Rebooting Your System

In order to reboot your system, set your thermostat to Heat and lower the temperature until the furnace shuts off. Go to your breaker panel and turn off the power to your thermostat and furnace system. Leave the breaker switch off for about a minute, and then turn your breaker back on.

Consider Replacement or Upgrade

If you have discovered your thermostat is beyond repair, it may be time to invest in a new one. Many different types of thermostats are available today.

According to the US Department of Energy (DOE) , investing in a programmable thermostat and setting back your temperature during the night or workday can save you up to 10 percent of your annual energy bills.

You may even want to look at smart thermostats that can adjust to your family’s personal schedule and “learn” from your settings to help you program future days.

If you have an old mercury-based thermostat, be sure to dispose of it properly. Call us for help with this if you’re unsure how to do it.

Fall Indoor Air Quality (IAQ)

Thu, 15 Oct 2020 09:00:00 GMT

With fall now upon us in Conway , cooler temperatures are here to stay. This transition from one season to another most definitely affects your home’s indoor air quality (IAQ) . And your indoor air quality directly affects your comfort in your home.

At Coastal Air + Refrigeration , we know in cooler weather people tend to spend more time indoors at home. Knowing this, it’s important to be sure your indoor air quality is protected, keeping both you and your home protected.

How Is Indoor Air Quality Affected in the Fall?

Think about it. Your South Carolina home’s indoor air is a composite of many sources: the outdoor air that comes through your open windows, the dander from your pets, the air in your basement which flows through your furnace, the harsh chemicals you may use in your cleaning products, the mold spores existing in the crawl space beneath your house—just to name a few.

In the warmer months, the open windows allow fresh air in on a regular basis, diluting the stale air in your home, and your air conditioner is keeping your home’s humidity in check. When the windows close and your air conditioner is turned off for the season, these good effects disappear until next year.

Now, the air that’s in your home simply circulates, and all those composites and particles in the home stay there. The humidity decreases, causing your body’s membranes and nasal passages to dry out, inviting harmful bacteria and viruses in. Drier air also wreaks havoc on allergy and asthma sufferers. This is all a recipe for health issues.

What Can You Do to Improve Your Home’s Indoor Air Quality?

In the cooler months with the windows continually closed and your furnace switched on , you need to take additional steps to protect the air you breathe in your home. You can prevent or lessen the possibility of some of the health concerns above by following these recommendations:

Use a humidifier . It’s so important to keep your home’s humidity levels between the US Environmental Protection Agency (EPA) recommendation of 30 to 50 percent. Drier air causes nosebleeds, cracked skin, respiratory problems, sinus issues, static electricity, and many other negatives. The comfort in your home isn’t only determined by its inside temperature.
Change your heating, ventilation, and air conditioning (HVAC) filters regularly, at least every three months . A good high-efficiency particulate air (HEPA) filter will catch the particles before they reach your lungs. There’s just so much floating in the air our eyes can’t even see.
Changing your filter makes such a difference. We at Coastal Air + Refrigeration suggest changing it monthly if someone in your home suffers from allergies or asthma, otherwise at least every three months. Regularly changing your filters also helps to increase your HVAC system’s life span by preventing those particles from running through the system.
Clean regularly . Many health challenges are caused by dust, dirt, pests, bacteria, viruses, and mold. Regular house cleaning, especially vacuuming and dusting, helps to prevent these from building up and getting into the air.
Also, when cleaning, switching to more natural cleaning products using essential oils instead of harsh chemicals can make a substantial difference in your home’s indoor air quality.
Have your heating system cleaned and checked before turning it on . Be sure to schedule your annual heating system’s maintenance appointment before using your heat for the first time. A proper cleaning and tune-up allow your system to run properly, helping to improve the indoor air quality and increase your system’s life span.
Open your windows daily . Even in the coldest temperatures, it’s a good idea to open a window in every room for at least a few minutes to invite some fresh air in. It helps to keep bacteria and viruses at bay.

Fall HVAC Maintenance

Thu, 08 Oct 2020 09:00:00 GMT

As the saying goes, “Time and tide wait for no one.” Whether you’re prepared or not, the summer months and warmer weather are gone, moving aside for fall and cooler temps. That means here in Conway you need to think about preparing your heating, ventilation, and air conditioning (HVAC) system for fall maintenance.

Maintaining your heating and cooling equipment ensures it’ll run smoothly the way it should when you need it. Investing your time and money in these seasonal HVAC maintenance tasks goes a long way to protect both your South Carolina home and your HVAC investment , including your wallet. Well-running systems are more energy efficient, so they end up costing you less to run all season long.

Fall Maintenance for Your Air Conditioner

Just because you won’t be turning your air conditioner on now doesn’t mean you should forget about it til the spring and summer months. Part of protecting your home and equipment is winterizing your cooling system.

If you’ve already had your air conditioner cleaned and checked by our Coastal Air + Refrigeration professionals before you used it this year, you can simply ask our heating and cooling professional to winterize your unit while he or she is out cleaning and checking your furnace. You can compare the maintenance checklist to what ENERGY STAR® recommends .

Things you can do yourself:

Clean off the outside unit (condenser) from debris and dirt. If involving water in the process, be sure to switch off the unit’s power or the circuit first.
Remove any branches, tall grass, or brush within a four-foot proximity to the unit.
Insulate any exterior-exposed pipes with foam pipe covers, wrapping them with duct tape.
Cover the unit with a plastic or vinyl cover. Some folks have an air-conditioner-specific cover. If you don’t, you can use a tarp. Be sure to secure the cover, in whatever form, with bungee cords or vinyl rope. Perform this step after your HVAC technician has already done his or her part in the winterization process.

Things to ask your technician to do:

Clear drain lines and pipes to avoid having standing water in your system all winter.
Clean the coil from dust and dirt.
Check the refrigerant charge, belts and pulleys, and ducts.
Clean and check the entire system if you haven’t had it done yet this year.

Fall Maintenance for Your Heating System

You should schedule your annual maintenance appointment for your heating system before you use it for the season, regardless if you have a furnace , boiler, or heat pump . This appointment shouldn’t be skipped, as keeping your heating system in good order will be sure it’s ready when you need it and keep it functioning properly throughout the season for you.

Things you can do yourself:

Stock up and change your filters every three months, but if you have allergy issues, monthly is advised.
Vacuum your vents to keep them clear of dust, avoiding extra filter buildup or decreased indoor air quality (IAQ) .

Things to ask your technician to do:

Clean and check your heating system, including (depending on whether you have a furnace or boiler) all the connections, controls, sensors, drains, ignitor, ducts, pipes, burners, valves, motors, thermostat(s), and smoke/carbon-monoxide detectors, and instruct you on anything you could do between your service visits.
Calibrate your thermostat to be sure the readings and heating are accurate.

What Are Zone Control Systems?

Thu, 24 Sep 2020 09:00:00 GMT

Some like it hot!

Others, not so much.

If you have a large home with multiple stories or a large household with family members who prefer different temperatures, consider installing a zone control system.

A zone control system —or zoning—only provides the necessary cooling or heating that each zone in your South Carolina home needs at the time. It not only adds to the comfort level of your home but can also lower your energy bills.

At Coastal Air + Refrigeration, we always look for ways to improve the comfort, health, and safety of homes and businesses in Conway and surrounding areas. Your heating, ventilation , and air conditioning (HVAC) system is a significant purchase—a big part of our job is to help ensure you get the maximum value from this investment.

How Do Zone Control Systems Work?

To create a zone control system, our experts will place dampers in the ductwork that distributes hot or cold air throughout your Conway home. Each zone you create is equipped with a thermostat that connects to a central control panel. When you adjust the thermostats in each zone, the control panel opens or closes dampers to distribute hot or cold air where needed.

Working with our team, you create the size and location of each zone throughout your home or business. You can turn one room into a zone, or an entire floor. The zones should be areas that either have different temperature requirements or have specific areas that have had trouble maintaining temperature compared to the rest of a zone.

Whatever you decide, you can count on Coastal Air + Refrigeration to help you achieve the most comfort in your home that comes with a zone control system.

Zoning Options

Installing a zone control is a money saver since it lessens the load on your HVAC system. Your furnace or air conditioner no longer has to struggle to heat or cool every room in your home. Here are some ideal zoning situations:

Homes with rooms that are hardly used
Home with concrete slab foundations, large windows, or high ceilings
Finished rooms in the attic or basement
Homes with multiple floors or intricate floor plans

Reducing the stress on your HVAC equipment extends the service life of your entire system. It also lowers your monthly utility bills. According to the US Department Department of Energy (DOE), heating and cooling your home accounts for upwards of 40 percent of your energy costs .

How do I know if I need a zone system?

Most homes can benefit from a zone control system. If your home has any areas that are uncomfortable compared to the rest of the home or you have different temperature requirements throughout your home, this system may help.

Larger homes with multiple systems also see huge benefits from a zone control system because there is no reason to heat or cool the home to a comfort level when some areas are not being used. Only maintaining a comfort level in occupied rooms can generate huge energy savings.

Many programable thermostats also have WiFi features so you can monitor and adjust the heating or cooling in the home; only the necessary energy is being used when no one is at home, or when people are only using certain rooms at certain times of the day.

These are significant utility savings that can occur while also increasing your home comfort! You will save money and make everyone in your home happy!

What If I Close Off Vents?

Our customers will occasionally ask if they can achieve the same result simply by adjusting the slats on the air vent covers. The answer is no.

Closing or partially opening a vent restricts the amount of air that exits the ductwork—but does not cause an air conditioner or furnace to produce less cold or hot air. By comparison, the zone control system not only redistributes airflow by operating dampers but also controls your HVAC equipment, signaling it when to run and when to stop. This eliminates unnecessary energy expenses.

Using air vents as a substitute for zone control may also contribute to air leakage and low airflow, among other problems. Those adjustable slats over air vents are designed to direct the flow of air into a room, not block it entirely.

Why Is My Air Conditioner Making Noise?

Wed, 16 Sep 2020 09:00:00 GMT

It’s normal for your air conditioner to create some noise when running—that simply means it’s working. Although older units are typically louder than newer ones, all air conditioning noises are not the same.

Despite your air conditioner’s age, any sound coming from the unit can still be bothersome. If your air conditioner is producing an unusual sound, that could mean trouble. So instead of risking injury to you or your system by poking around the unit yourself, play it safe and call a professional to come inspect it for you.

To avoid any of these potential issues, we at Coastal Air + Refrigeration recommend getting a maintenance inspection at least once a year to determine the health of your air conditioner, regardless its age or noise level. According to ENERGY STAR® , “proper maintenance by a qualified professional technician is one of the most important steps you can take to prevent future problems.”

Air Conditioner Common Noises

We have heard our fair share of unusual hums, buzzes, and clatter coming from air conditioners throughout the years, so below is a list of the most common noises we have found and the problems they can indicate.

Rattling

A distinct rattle could be the cause of a loose bolt, screw, fastener, or another small part that fell into the vents. It could also be your compressor or an issue more serious than a loose part. If you suspect any of these, you need one of our skilled technicians to look into the problem further.

Grinding

A grinding or noticeable rubbing or scraping sound most likely means there is a problem with one of the fan motors. It’s also possible the noise can be originating from a worn bearing or a loose or damaged belt. This is sometimes more commonly associated with older air conditioning systems.

Popping

A popping noise might be coming from your air ducts when your air conditioner turns off and on. This usually indicates a problem with your ductwork and not necessarily a problem with your central air. Even though these potential problems can be easily confused, ductwork still ages the same as any other heating, ventilation, and air conditioning (HVAC) equipment and requires routine maintenance to be sure it’s functioning efficiently and effectively in your home.

Hissing

If you hear a hissing, it’s likely this type of noise is generating from within your ductwork, so let one of our knowledgeable technicians take a closer look. We can pinpoint the source and tell you if there is a bigger issue involved, such as a refrigerant leak, where a more detailed repair would be necessary.

Your air conditioner is a complex piece of machinery with many moving parts and, like a car, it requires regular maintenance by experienced professionals like ours at Coastal Air + Refrigeration to diagnose and treat any potential problems. Don’t ignore the signs if you suspect there could be an issue with your air conditioner. Give your unit the proper attention it needs to operate in prime condition for years to come.

Why You Need Whole-House Humidity Control

Thu, 27 Aug 2020 09:00:00 GMT

When indoor plumbing became more popular in the 1940s, a whole new level of comfort and convenience began for homeowners. However, with that convenience came new challenges. One of those challenges is controlling humidity levels so they remain safe and comfortable inside your home. According to HVAC.com , the ideal humidity level is between 30 percent and 50 percent.

Today, the combination of indoor plumbing as well as seasonal humidity can contribute to issues such as mold growth. Our professionals at Coastal Air + Refrigeration want to share with you some tips on controlling humidity and, furthermore, humidity control consequences in your Myrtle Beach home.

Kitchen Considerations . When you are cooking in your kitchen, you will notice a fair amount of steam being released into the air. In order to reduce humidity in your kitchen, try to remember to cover your pots while cooking and use your range hood ventilation system liberally.
Laundry Tips . Make sure your dryer is properly vented to the outside so all that moisture is deposited outdoors. Better yet, on warm days, plan to hang out things like sheets, towels and other larger items on an outdoor clothesline.
Bathroom Habits. By taking shorter showers and making sure your bathroom vents are turned on, you can minimize the amount of moisture released into your home. Consider exploring special exhaust fans that turn on automatically when certain humidity levels are reached. Be sure all exhaust fans in the kitchen and bathrooms vent to the outside, not into your attic.
Humidifiers . During the winter months, you may use a humidifier to help combat dry air in your South Carolina home. However, during the warmer summer months, you want to make sure that your furnace humidifier and other portable humidifiers are turned off or used sparingly.
Air Circulation . When air is circulating, it is much less likely for humidity to build up. During the humid summer months, be sure to run the fan on your furnace all the time. You can also minimize humidity buildup by keeping your curtains and drapes open as well as interior doors such as closets. To keep air flowing around your home, be sure air registers are not blocked and try not to close off unused rooms.
Special Areas . If your home has moisture-producing areas such as a greenhouse, indoor pool, or hot tub, be sure to keep the doors and windows to these areas closed but add plenty of air ventilation within them.
Basement and Crawl Spaces . If you have exposed earth in your home’s basement and crawl space, you’ll want to install ground sheeting. Also, be sure that your outdoor property is graded so water flows away from your foundation and that you take care of weeping tiles and leaking gutters immediately.
Chimneys . Be sure to have your chimney inspected and cleaned each year. Clogged chimneys can not only be a fire hazard, but also create high humidity issues.
New Additions . Remember that new building materials may take time to dry. If you have recently put on an addition to your home, be sure to increase ventilation immediately after construction.
Dehumidifiers . Many newer homes are well insulated and sealed to be energy efficient. However, the downside is that humidity can get trapped inside. If your home is new, may want to consider purchasing a dehumidifier to remove excess moisture.
Leaks . If you happen to have any plumbing problems or other water leaks in your home, be sure to identify and repair them as soon as possible. Pooling or standing water is a known breeding ground for mold.
Firewood . If you happen to have a fireplace, try to dry and store your firewood outdoors. Green wood releases a fair amount of moisture inside home.

Leaky Ducts and You

Wed, 19 Aug 2020 09:00:00 GMT

Though it’s a hidden element in your home, ductwork is crucial to your home comfort. It’s the system by which warm or cool air circulates throughout your home. And all your conditioned air, whether it’s warmed or cooled, has to travel through these ducts. As such, it’s essential to have a well-maintained duct system in your home.

What Is Ductwork?

At Coastal Air + Refrigeration, we take ductwork very seriously. Our heating and cooling professionals know what an important role your home’s air ducts play in so many areas—your comfort, energy bills, and health most specifically. Here in Myrtle Beach , we see the difference between ductwork that is well sealed and maintained and ducts that are not on a regular basis.

Your South Carolina home’s ductwork or air ducts are corridors through which your warmed or cooled air travels back and forth to your heating, ventilation, and air conditioning (HVAC) system and to the vents in your home. It’s comprised of a system of ducts and pipes, typically metal, and has seams that are expertly sealed when they are first installed. Several places may also be insulated to help reduce energy loss.

Why Don’t You See Your Ducts?

Most of your ductwork is hidden behind walls or in places not as frequently used as other areas of your home are. You most likely don’t see the majority of it. Often it’s in the attic, and for most of us, ductwork can fall into the out-of-sight, out-of-mind category. But this mindset can compromise your indoor comfort, cost you money, and even affect your health.

Why Seal and Insulate Your Ductwork?

Properly sealing and insulating your ducts prevents your home’s treated air from leaking out the duct system. According to the US Department of Energy (DoE) , 20 to 40 percent of energy is lost from most duct systems. Ducts are usually constructed from sheet metal or fiberglass, both thin materials. It’s easy for your circulating air to leak through these materials as well as through any duct seams.

Additionally, your duct insulation protects your ductwork from mold and mildew growth, because your home’s cool air travels through ducts located in warm areas of your house. This can cause condensation in your ducts, which encourages that mold and mildew. Insulating your ducts regulates the temperature and prevents this scenario.

Why Maintain Your Ducts?

Over time, your ductwork’s seals can deteriorate and rust, and your insulation can lose its effectiveness, both causing you problems. That’s why it’s so important to regularly have professionals inspect your duct system and address any leaks.

Poorly maintained and leaky ductwork can cause the following problems:

An increase in your heating and cooling bills. Leaks in your ducts can occur where the ducts are joined. Leaked air is wasted air. Your furnace or air conditioner has expended energy, that you pay for, to heat or cool the air. When that air does not make it to the desired locations in your home, your HVAC unit has to work twice as hard to make up for the energy lost—it’s essentially throwing away money.
A negative effect on your home’s indoor comfort. With energy leaking from your ductwork, your inside temperature can continuously vary and leave you without the comfort you expect. No matter what type of heating, ventilation, and air conditioning (HVAC) system you have and how energy efficient it is, if you have leaky ducts, your system can’t provide you an efficient level of comfort and live up to its potential.
Poor health for you. Leaks can cause undesirables from the air to leak into your duct system, meaning contaminants like exhaust, fumes, carbon monoxide, or many other pollutants can enter your duct system and circulate around your home without you knowing it. This can cause a myriad of problems including causing respiratory problems or exacerbating problems you may already have, such as asthma or allergies.

Why Is My AC Blowing Hot Air?

Thu, 30 Jul 2020 09:00:00 GMT

It’s the first really hot day of summer in Myrtle Beach when the floor fans and the open windows just don’t cut it anymore. You head over to your thermostat and select “air conditioner” and wait for that refreshing icy air to start blowing out of your vents. When you check a few minutes later, you feel only hot air. Why?

Many reasons can cause an air conditioner to malfunction , resulting in warm or hot air blowing through your vents. Our Coastal Air + Refrigeration professionals want to help you diagnose those problems quickly and then get them fixed, so you can cool down your family and your home.

Start at the Thermostat

The thermostat controls when your heating , ventilation and air conditioning (HVAC) system turns on and off, depending on what temperatures you have designated. When your air conditioning system blows hot air, start by checking your thermostat.

Be sure it’s set correctly and not set to heat. You need to set your thermostat to cool, being sure you’re not only setting the fan function. If you are sure you have it set correctly, there may be an issue with how your thermostat is sending messages to your HVAC system or some other problem. Call us to come out and fix the issue for you.

Lack of Air Circulation

Air conditioners need plenty of air circulation to operate correctly. Start by checking your air filter and being sure it’s clean . Clean air filters can not only improve your air conditioner’s performance but can help save significant amounts of energy .

Then, head on outside and be sure your unit is not buried under leaves, grass, weeds or other yard debris. If there are things blocking the outside unit, take the time to clear them away. Once that’s taken care of, check the inside unit for any blockages or clogs that may be restricting airflow there.

Too Much Ice

Sometimes restricted airflow and dirty condenser coils can cause a buildup of ice on the outside portion of your air conditioning system. If too much ice builds up, it can cause your air conditioner to malfunction and blow only hot air.

If a great deal of ice exists, you may need to turn off your entire system and allow it to defrost. Once the ice melts, clean the condenser coils, and turn your system back on to see if it functions properly. If it doesn’t, call one of our professionals to help.

Low Refrigerant Levels

Your air conditioner needs a certain level of refrigerant at a particular pressure to operate efficiently. If you have a refrigerant leak or you notice your refrigerant levels are low, you’ll need to call a professional to come in and replenish the refrigerant.

This is a toxic, regulated chemical, so it’s important to rely on our experts to assist with this problem. Refrigerant leaks are damaging to the environment, so be sure to get that repaired as soon as possible.

Mechanical Problems

An air conditioner has many complex parts, and if any of them malfunction, it can cause your unit to blow hot air. If you cannot resolve your air conditioning problem with simple fixes, it may be time to call an HVAC professional to inspect your air conditioning system.

One of our trained technicians can check the condition of your blower, condenser, and evaporator as well as be sure your electrical connections are secure and working correctly. You’ll have the added benefit of having a professional give your air conditioning system a complete cleaning and tune-up , which should help you minimize repair bills over the long term.

The Problem With Clogged Air Filters

Tue, 23 Jun 2020 09:00:00 GMT

Busy careers, bustling families, engrossing hobbies, and overwhelming responsibilities keep most people busy day in and day out. It’s understandable why worrying about the air filter in your heating , ventilation, and air conditioning (HVAC) system is probably way down at the bottom of the priority list.

However, our team at Coastal Air wants to pass along a gentle reminder about the importance of this small maintenance task. It’s one that takes only a minute or two but can make a huge difference in your Conway home.

Respect Your Air Filter’s Responsibilities

Think about it. Your air filter is responsible for cleaning every bit of your indoor air as it circulates through your home, providing life-giving oxygen to you and your family. It’s responsible for filtering out dust and dirt as well as things like pet dander and allergens. It has a big, important job to do—one that can contribute significantly to your family’s health, comfort, and financial situation.

Changing your air filter in your South Carolina home is something that usually needs to be done a few times a year. When you think about it, it’s really a small price to pay for such a big job.

Health Implications of Clogged Filters

When air filters are dirty, they cannot do their best job cleaning your indoor air. Since most people spend the majority of their lives inside, it can significantly impact your overall health. Outdoor pollen can make its way into your home, and daily living will generate dust and dirt easily inside your house. In addition, if you have pets, you smoke, or you have any remodeling projects underway, all of these can add to poor indoor air quality .

Depending on the type of air filter you choose, you can minimize or eliminate many of these allergens easily. Keeping a small stash of filters on hand to help you remember to change them can help.

If you have family members who suffer from asthma or allergies, they will suffer much more in a home with a clogged air filter. Even those with strong constitutions may feel the effects of poor air quality on their overall health. If you notice health effects already, it may be time to investigate higher quality air filters such as high-efficiency particulate air (HEPA) filters that filter out the majority of the smallest particles.

Comfort Implications of Dirty Filters

An HVAC system is designed to deliver either heating or cooling services to your living space so that you and your family can be comfortable. Clogged air filters can affect the overall performance of your HVAC system, making it work harder and perform less efficiently. In addition, an HVAC system helps control the humidity in your home. Dirty air filters can negatively affect humidity levels in your home. Failing to perform this simple maintenance task can then reduce the overall comfort levels in your home.

Financial Implications

Clogged air filters can significantly impact the performance of your HVAC equipment. When filters are dirty, air has trouble moving through the system. That means your air conditioner or furnace must work harder to push air through the system. This can wear out components faster than necessary, shortening the overall life of your HVAC equipment. It can also mean additional repair costs and higher levels of maintenance .

In addition, it will take more energy to deliver heat or cooling to your home, which means your utility bills will be higher on a regular basis. In fact, according to the US Department of Energy (DOE) , simply changing your air filters can reduce your energy consumption by between 5 and 15 percent every month.

An Easy Solution

The solution to these issues is simple: remember to change your air filters once every three to six months or according to your manufacturers’ recommendations. This small maintenance task will take only a few minutes, and it can mean better health, increased comfort, and less impact on your pocket book.

Why Is a Home Dehumidifier Important?

Mon, 15 Jun 2020 09:00:00 GMT

Although most Conway homeowners understand the importance of having a working heating , ventilation, and air conditioning (HVAC) system to provide heating and cooling throughout the year, some people don’t realize the equally important factor of controlling a home’s humidity levels as well.

Our professionals at Coastal Air want to provide you with the information to create a healthy, comfortable environment for you and your family. Here is some important information about dehumidifiers and the role they play in your home’s health and comfort.

What Is a Dehumidifier?

A dehumidifier is a piece of equipment that removes moisture from the surrounding air. It works opposite of a humidifier , which adds moisture to the air. Dehumidifiers are often used in humid climates during the summer months in areas where weather turns both hot and humid, or year-round in humid areas of a home.

These systems work similar to air conditioners by pulling in warm, moist air throughout your home using the ductwork. This air then passes over coils that contain coolant, which forces the moisture to condense on the coil and then fall into a container. Room dehumidifiers may need to be emptied occasionally, or you can attach a drainage tube to allow the unit to constantly drain

What Are the Benefits of a Dehumidifier?

By removing the moisture from your South Carolina home, you’ll not only make your home feel cooler and more comfortable, but you’ll also create an environment that is less likely to allow things like dust mites, mold spores, and other allergens to thrive. For both you and your home’s health, you want to strive for the highest indoor air quality possible .

According to ENERGY STAR ®, the ideal humidity levels for a residential home generally falls between 30 and 50 percent. However, the range can vary depending on the outside temperatures. You may want to invest in a communicating thermostat that senses humidity to continually monitor the humidity levels in your home and control it accordingly.

Another thing to remember is that new and remodeled homes may be more likely to trap moisture due to advances in insulation and building practices, creating much tighter homes. Although creating a tight home helps it to be more energy efficient, it can result in indoor air quality issues.

What Are Signs You Need a Dehumidifier?

You may be able to notice signs around your home that indicate your indoor moisture levels are too high. Here are some things to watch for:

Condensation on your windows or doors. If you see small drops of water beading or a fog layer building up on the inside of your windows, you may have a humidity problem. This moisture could eventually rot the wood around your windows or allow mold to grow.
Mold growth. Check your basement ceilings and the corners of your walls for mold growth. Moisture rises, so you will often see the first evidence of mold in these areas.
Musty odor. If you detect a musty smell in your basement, crawl space, laundry room, entrances, or garage, you may be fighting a moisture issue.
Basement watermarks. Many homes may have reoccurring spring water runoff, which can seep into a basement. Look for white or grey water-level marks as evidence of this problem.
Blistering paint or peeling wallpaper . Excess moisture in the air can eventually penetrate the surrounding walls. It can cause your paint and wallpaper to lose adhesion, resulting in bubbles or peeling.
Creaky doors, windows, and floors. As wood absorbs moisture, it will expand. This can cause joints, screws, and the structural frame of your home to loosen and creak.

How Does an Air Conditioner Work?

Fri, 29 May 2020 09:00:00 GMT

As a homeowner here in South Carolina , it’s always a good idea to learn as much as you can about your appliances. That means knowing their basic operations, what features are included, and if any necessary upkeep is involved. Needless to say, this is no exception for your air conditioning (AC) unit.

How It All Began

The modern air conditioner is designed to transfer cool air throughout your home to keep you comfortable during the year’s hottest months. This marvel was originally invented in 1902 by Willis Haviland Carrier. He developed the air conditioner to solve a humidity problem at a printing plant in Brooklyn, New York, and was ultimately credited with creating a system of chilled coils to maintain a constant temperature.

Today, the Energy Information Administration (EIA) reports that 87 percent of homes in the United States use air conditioners and account for nearly 12 percent of total energy costs each year. That’s why we at Coastal Air in Conway want you to know all about your cooling system and what it takes for your trusted investment to keep running efficiently for years to come.

How It Works

As a consumer, it’s important to understand the key elements of your cooling system, and that starts with knowing your air conditioner’s five main functional components and how they work together:

Compressor —the key to refrigerant conversion

Working like a pump inside your unit, this is often considered the “heart” or “engine” of your air conditioner. The compressor is located in the outdoor portion of your system, which is referred to as the condenser. Once the system is activated by your thermostat, the compressor starts to pull in a low-temperature, low-pressure refrigerant in gas form from your system. The gas is then compressed to a higher pressure and temperature before being released to the condenser coil.

Condenser —outdoor coil

The condenser coil is also located in the outdoor portion or your system. It’s made up of a piping sequence with thousands of small fins on it. The refrigerant runs through this coil after exiting the compressor. A fan pulls outside air across the coil to remove the heat from the refrigerant with the assistance of the fins for maximum heat dispersement. This process causes the refrigerant to convert back to a high-pressure liquid state prior to entering the expansion valve.

Expansion valve —mechanical component regulating refrigerant

This critical part of the system is responsible for controlling the conversion and amount of refrigerant passed through to the evaporator. This is typically located on the indoor portion of your system. High-pressure liquid refrigerant is forced through a small orifice in the valve that causes the pressure reduction as it passes through. The refrigerant expands to a liquid/vapor mix at this point that’s allowed to enter the evaporator coil.

Evaporator —indoor coil

The evaporator is a series of piping creating another coil that the liquid/vapor refrigerant passes through and absorbs the heat from the air passing over it. This lowers the temperature of the air that is then distributed throughout your home by way of its ductwork, lowering the temperature throughout the space. The cycle continues when the refrigerant makes its way back to the compressor to keep the air in your home regulated to the desired temperature setting on your thermostat.

Blower —indoor fan

The blower is a fan that pulls warm air through the air filter in the return ductwork. It pushes that air over the evaporator coil to be distributed via your ductwork throughout your home.

In addition to cooling your home, an air conditioner can also help address humidity in your home by humidifying and dehumidifying. Some units include a moisture collection pan that absorbs the moisture from the air as the refrigerant absorbs heat.

Spring Money-Saving Tips

Tue, 19 May 2020 09:00:00 GMT

Everyone loves to save money, and it’s a good idea to review different aspects of your budget now and again to see if there are more opportunities you have missed in the past. In the springtime, considering how you can reduce your energy bills is always a great idea.

According to the US Department of Energy (DOE), air conditioners use about 6 percent of all electricity in the country at a cost of roughly $29 billion to homeowners.

If you can reduce that usage in Conway , you will be able to make a difference in our environment and save yourself some money as well. Take some of the following ideas from our professionals at Coastal Air to heart and make some money-saving resolutions today.

Tune Up for Efficiency

All air conditioners work more efficiently if they have clean filters, enough refrigerant, spotless coils, and plenty of room for air circulation.

Although you can take care of some of these maintenance items on your own—clearing away fallen yard debris from around your outside condenser unit and regularly changing filters, you should engage one of our highly trained professionals to help inspect and clean your air conditioning components. Our experts can also check your ductwork and be sure you are not losing your cooled air before it reaches its destination.

By investing in regular maintenance, it’s less likely your unit will break down in the dog days of summer. That’s an extra bonus.

Work with Mother Nature

Find ways to use the outdoor conditions to your advantage when it comes to saving energy. For example, during the spring and the fall when nighttime temperatures cool down, open all your windows to let the cool breezes in.

Then, first thing in the morning, close your windows and pull your shades to trap the cooler air inside. You can also consider planting trees to shade your home in the future.

Circulate Indoor Air

Consider investing in floor fans or ceiling fans to help move your indoor air. Fans use a lot less energy than air conditioning systems and do a good job cooling down your home in moderate temperatures. You can also run the fan on your heating, ventilation, and air conditioning (HVAC) system or install a whole house fan that pulls in fresh air from the attic.

Relocate Heat Outside

The sun is not always the biggest culprit in generating indoor heat. How often do you find that your appliances are competing directly with your air conditioner?

Instead of turning on your oven or stove, consider grilling outside to keep that heat out of your home. Or get a little creative and find some great cold meals to prepare instead.

The clothes dryer is another heat producer in most South Carolina homes. Instead of running your dryer, put that springtime sun and a laundry line to work.

Block and Reflect

Another idea to reduce the heat and associated energy bills is to invest in energy-efficient windows, seals, and insulation to keep the cold in and the heat out. You can also install light-colored window coverings to block sun in the warmest part of the day.

Energy-efficient, reflective roof tiles or a coat of lighter exterior paint can do wonders in reflecting the heat of the sun away from your home’s outside.

Rely on Technology

At the very minimum, install a programmable thermostat that will automatically adjust your temperature requirements while you are away or asleep. Smart technology is advancing each day, and in some homes, rooms can now detect when you are present in them and adjust the temperatures accordingly. You can also control and monitor air conditioning usage from afar using a smart phone.

Don’t Forget the Little Things

Every light that’s left on when not in use generates heat as well as all those electronic devices. Consider switching to LED lightbulbs and turning off electronic gadgets when they are not being used to save money and reduce heat.

What Indoor Air Quality Accessories Can Help Keep Me Healthy?

Tue, 28 Apr 2020 10:30:00 GMT

According to the Centers for Disease Control and Prevention (CDC), the novel coronavirus disease 2019—also known as COVID-19—can cause mild to severe respiratory illness when an individual is exposed to the virus.

Even before the outbreak, adults on average spent nearly all their time indoors at work or at home. In fact, the US Environmental Protection Agency (EPA) reports this amount of time reaches upwards of 90 percent for most people .

Add it all up, and you just can’t stress enough the importance of good indoor air quality.

Our Coastal Air team wants to share with you the following list of the d ifferent indoor air quality accessories available out there. Making an investment in one or more of these helpful technologies and tools for your home just might help you and your family breathe a little easier.

Dehumidifiers

During the summertime in Carolina Forest, there is a really good chance you will be facing the opposite-of-winter humidity problem. When humidity levels are high, summer months can feel a great deal hotter. Too much moisture in the air can make cooling down more difficult, cause condensation or moisture damage to the structure of your home, and contribute to mold and other allergen growth.

While a well-maintained air conditioning system brings down the heat and can help take some moisture out of the air, you may want to invest in a whole-house dehumidifier , or opt for a stand-alone unit for a space like your basement.

Humidifiers

In South Carolina winters when the air is cold and dry, whole-house humidifiers can be particularly beneficial, keeping relative humidity levels at an ideal of about 45 percent. This means fewer scratchy throats, and less dry skin and static electricity. Plus, humidifiers can help protect your furniture, wood floors, and musical instruments from shrinking, warping, and other damaging issues.

Electronic Air Cleaners

Attached to your heating, ventilation, and air conditioning (HVAC) system, electronic air cleaners are a whole-house solution. An ionic system, a high-efficiency particulate air (HEPA) filter, and static electricity are utilized to kill or trap up to 99.98 percent of all allergens. Performing an almost complete job, these cleaners combine the best of all available indoor air purification technologies.

Air Scrubbers

Viruses, bacteria, mold, odors, vapors, gases, and volatile organic compounds (VOCs) are among the substances attacked. Working with your HVAC system, air scrubbing systems are a relatively new technology. Air is treated with an ultraviolet (UV) light while it is forced through a titanium dioxide-coated component. Additionally, contaminants are transformed into oxidizers, meaning more pathogens can be eliminated in the surrounding air—and even on surfaces.

UV Air Treatment Systems

In hospitals and other healthcare facilities, UV lights are a mainstay to kill viruses, bacteria, and other pathogens. You can do the same: piggyback on this technology by investing in a UV home air treatment system. Shortwave UV lights attacks viruses, bacteria, mold, and other pathogens because air is forced through a UV purifier.

Ionic Air Purifiers

Improving indoor air by removing nearly everything except for odors and smoke, the most advanced ionic air purifiers can basically clean themselves. Early models of these systems simply emitted negative ions that bonded with positively charged common indoor air pollutants; particles then grew heavy and fell onto surfaces and floors for a cleanup via dusting and vacuuming. These are highly effective systems.

HEPA Air Purifiers and Filters

Air purifiers and air filters branded with the HEPA designation are designed to remove 99.7 percent of all particles sized over 0.2 microns. So consider airborne particles— such as mold spores, pollen, household dust, and pet dander—as goners. Combine HEPA purifiers and HEPA filters with HEPA vacuum bags to make a big improvement in your indoor air. Just remember, it’s important for you to change HEPA filters regularly.

Activated Carbon

Remove smoke, gases, chemicals, odors, and other fumes from the air in your home in good order with activated carbon purifiers. Many of them tackle pollutants in combination with a HEPA purifier. Successfully manage nearly all of the common indoor air issues in your home by adding a UV purifier.

Air-to-Air Exchangers

Designed to bring in and treat outdoor air while pushing out the stale indoor air from your home, these air-to-air exchangers automatically adjust the temperature and humidity of outdoor air prior to circulating it through your ductwork. This is then circulated throughout your home for you to breathe.

Air Filters

To keep large particles at bay before your indoor air enters your furnace or air conditioning system , an air filter is required on all HVAC systems. Ranging in quality and price, filters on the lower end of quality catch only large particles, while HEPA filters trap some of the smallest.

In order to keep your air clean and your equipment working properly and efficiently, it’s very important to change your air filter on a regular basis; do so at least every three months, or according to the manufacturer’s instructions. During times like these, we recommend changing your filter much more frequently, even weekly or biweekly is not extreme.

What Does Indoor Air Quality Have to Do With Allergies?

Mon, 23 Mar 2020 09:00:00 GMT

Did you know the average American spends nearly 90 percent of life indoors? That’s why it is increasingly important to ensure indoor air quality (IAQ) is clean and healthy. If your Conway home is facing air-quality issues, you may be suffering anything from minor discomfort to significant allergy or health problems. Our team at Coastal Air wants to help keep your home’s indoor air quality high and you and your family healthy and comfortable.

Understand the Scope of the Allergy Issue

According to the American Academy of Allergy, Asthma, and Immunology (AAAAI) , roughly 10 to 30 percent of people suffer from allergies.

Although some common allergens originate outdoors, such as grass and tree pollen, they can still make their way into your home. Dust and dust mites are present in every South Carolina home, causing an allergic reaction for many. Common pets such as cats and dogs shed hair and dander, which affects air quality. Other indoor allergens may include mold, fungus, and chemicals released from paints and carpets.

Individuals react to allergens differently. Some just suffer from minor sneezing and itchy eyes. Others may have significant respiratory problems that can interfere with daily life. Remedies from over-the-counter medications to allergy shots can be used to battle this common ailment. However, most health care professionals will encourage avoiding allergens in the first place as the best line of defense.

Improve Air Quality With an Air Conditioner

Most heating , ventilation, and air conditioning (HVAC) systems have built-in air filters designed to address basic indoor air quality issues. Standard filters can trap large particles, and with regular filter changes, this can improve your indoor air quality.

Homeowners who suffer from allergies may want to invest in a high-efficiency particulate air (HEPA) filter, which can trap very small particles, helping to clean the air further. Pet dander, dust, and small fibers from paper and clothing can be filtered out easily.

Air conditioners also dehumidify the indoor air, which discourages the growth of other allergens such as mold and fungus.

Consider Installing Air Purifiers

Many different kinds of air purification systems are available on the market today. Each has a different strength and purpose.

For instance, if you are concerned about bacteria and viruses, you may want to consider an ultraviolet (UV) air cleaner. These were originally used in hospitals and can also kill mold and pathogens. Smoke and odors, on the other hand, are best removed with activated carbon filters.

HEPA air purifiers work similarly to HEPA air filters used on HVAC systems. They work to filter dander, pollen, mold spores, and dust.

Another popular air cleaner is the ionic air purifier. These force allergens such as dust to become heavier by attaching negative ions to them. Allergens then accumulate on carpets and surfaces to be cleaned up.

Some more advanced systems may include a static electricity, HEPA filter and ionic purifier in a single unit that works with your HVAC system.

Clean Air Ducts to Remove Allergens

Air ducts carry your heated or cooled air throughout your home from your central HVAC system. Often, common allergens such as dust, dirt, dander, and other debris can build up in your duct system. Over time, these allergens may be transported to the living areas of your home.

Many HVAC companies offer air duct cleaning services that use high-powered vacuum systems to clean out these allergens from your air ducts. You may want to research this option as a possible action item to improve the indoor air quality of your home.

What You Need to Know About Carbon Monoxide Poisoning?

Mon, 09 Mar 2020 09:00:00 GMT

We know how serious carbon monoxide (CO) poisoning is. Our Coastal Air professionals provide maintenance and service on all possible carbon-monoxide-producing appliances, as well as carbon monoxide detectors for your Conway home and office.

What Is Carbon Monoxide?

Carbon monoxide is a poisonous, odorless, and tasteless gas. It’s formed by the incomplete combustion of carbon, or by the incomplete burning of natural gas and other things containing carbon.

Many times it’s mixed with other gases you can actually detect because they emit odors. Carbon monoxide can result when you burn gasoline, kerosene, oil, propane, coal, wood, and the like. It is also a by-product of an internal combustion engine.

What Is Carbon Monoxide Poisoning?

When you inhale carbon monoxide, it displaces the oxygen in your blood and therefore deprives your heart, brain, and other organs of oxygen. The severity of your exposure is related to the level of carbon monoxide in the air and the duration of your exposure. If there is a large amount present, it will work very quickly, causing you to pass out or suffocate.

A small carbon monoxide leak in your home may cause gradual and mild symptoms you may not notice until it’s too late. A larger leak, typical in more industrial environments, would cause sudden exposure, loss of muscle control, and, in some cases, death.

The Centers for Disease Control and Prevention (CDC) estimates that 400 people per year die of carbon monoxide poisoning, 20,000 more visit the emergency room, and 4,000 people are hospitalized.

What Are the Symptoms of Carbon Monoxide Poisoning?

Symptoms of carbon monoxide poisoning range from mild flu-like symptoms to more serious and dramatic symptoms, like loss of consciousness and breathing issues. The severity is again related to the levels and length of exposure.

Here are just some of the symptoms you could experience:

Headache
Dizziness
Weakness
Upset stomach
Vomiting
Chest pain
Confusion
Shortness of breath
Blurred vision
Loss of consciousness

Carbon monoxide can be especially dangerous to those sleeping or intoxicated and for young children and elderly. It may cause death before any symptoms are noted.

What Is a Dangerous Carbon Monoxide Level?

Most people will have no symptoms at 1 to 70 parts per million (ppm). If you have someone in your house who is more susceptible, such as someone very young or old, you may see symptoms at any level.

But for the average person, you will not see any symptoms until the levels get above 70 ppm. A 150 to 200 ppm level will cause disorientation, unconsciousness, and death.

How Can I Prevent Carbon Monoxide Poisoning?

Here in South Carolina , there are a number of things you can do to prevent poisoning and keep the carbon monoxide levels down in your home or office:

Be sure you operate all appliances according to the manufacturers’ guidelines and read all owner’s manuals before attempting to service or clean anything. Never service your fuel-burning appliances yourself. Have a trained professional install, service, and clean any appliances that utilize combustion of any kind.
Have one of our professionals inspect your heating system annually, if not more, for any leaks or potential blockages, corrosion, or disconnections.
Never run any gasoline-powered appliance or generator in or near an enclosed space. Even with proper ventilation, carbon monoxide levels can build up rapidly and cause death or loss of consciousness. The same is true for any kind of combustible appliance, including camping stoves, gas grills, and other fuel-burning devices or equipment.
Do not use your gas stove or other appliances to heat your home.
Never leave your car running in the garage, even with the garage door open.
Install a carbon monoxide detector. A carbon monoxide detector or alarm is a device that measures the level of carbon monoxide in the air and alerts you when levels reach too high. Although this is not a substitute for proper carbon monoxide safety procedures, this can aid in your protection. Install an alarm near any area where people sleep in your home. People who are sleeping are often the most at risk of death. They can breathe in lethal doses of carbon monoxide before they would ever wake up and exhibit symptoms.

What Are the Different Types of Furnaces?

Mon, 24 Feb 2020 10:00:00 GMT

If you happen to be in the market for a new furnace , you may be overwhelmed by the number of options available. Our professional team at Coastal Air would like to make it a bit easier by providing some basics on the different types of furnaces on the market today. We hope this information can help you make the best decision for your family.

Furnaces by Operation

Furnaces sit at the heart of your South Carolina home’s heating, ventilation, and air conditioning (HVAC) system. They not only provide the heat for your home in the cooler months, but they also participate in the cooling of your home in the summer because furnace blowers circulate cooled air as well as warmed air. They can be classified in many different ways. Let’s start by looking at the different levels of operation.

Single-Stage Furnace

Single-stage furnaces have only one stage of operation. That means they can either be turned on or turned off. When a single-stage furnace is on, it operates at one consistent speed.

As a result, it’s more likely you’ll have hot and cold spots in your Conway home with greater variance in temperature. In some cases, you can experience between a 4 and 6 degree temperature difference.

In addition, you’ll use more energy turning on and off your system throughout the day. However, this is the most basic type of furnace and, therefore, the least expensive to purchase—and the easiest and cheapest to install.

Two-Stage Furnace

Two-stage furnaces give you slightly more control in how you heat your home by providing a full-speed and a half-speed setting. They deliver heat more efficiently and can keep your home at a more consistent temperature. In addition, two-stage furnaces operate more quietly at half speed.

Variable Speed Furnace

Finally, variable speed furnaces modulate both the speed and the heat output based on the outdoor temperature and the desired indoor temperature. You can often keep your home within half a degree of your desired temperature.

Since variable speed furnaces only work as much as you need them to, they are the most energy-efficient type of furnace. Variable speed furnaces also deliver the best air quality , as the fan continually circulates air through the filter, even when the furnace isn’t heating.

Although these furnaces cost the most upfront, you should be able to recoup some of that investment in reduced energy costs over time.

Furnaces by Fuel Type

Another way to classify today’s furnaces is by what kind of fuel they use to generate heat. Most furnaces are gas, oil, or electric. However, propane, wood, and coal furnaces can also be used.

Gas Furnace

Most homes in the United States operate natural gas furnaces today. Municipalities distribute gas through buried pipelines to residential homes. When the natural gas reaches a home, it jets along the furnace’s burner to ignite the fuel. This increases the temperature of the air in the heat exchanger, and warm air is circulated throughout your home’s air duct system .

Natural gas provides reliable heat, and fuel costs remain relatively low and stable when compared with other fuels. According to Consumer Reports , high-efficiency natural gas furnaces can achieve an efficiency rating of up to 97 percent.

Oil Furnace

Oil furnaces are more popular in remote areas where natural gas lines are not available. In this case, homeowners must purchase tanks of oil to store, and then replace the tanks as usage requires.

Oil furnaces are relatively inexpensive and last nearly twice as long as gas furnaces with proper maintenance. Oil prices, however, fluctuate quite a bit, which makes your ongoing fuel costs unpredictable. These furnaces also require ongoing cleaning of soot and ash buildup to remain in good working order and are not as efficient as gas furnaces.

Electric Furnace

Another furnace option if you don’t have access to gas lines in your home is an electric furnace. These furnaces employ electric heating elements to heat the surrounding air.

Electric furnaces are usually affordable and frequently smaller than other furnaces. Their disadvantage is they’re not as efficient as gas furnaces.

Why Is IAQ Important?

Mon, 03 Feb 2020 15:36:00 GMT

Energy-efficient homes are more common than ever. Although they provide many benefits, including reducing overall energy usage and a smaller carbon footprint, they come with some disadvantages as well.

What Disadvantages?

The most significant disadvantage is poor indoor air quality. Tightly sealed Myrtle Beach area homes prevent heated and cooled air from escaping as easily, but they also contribute to the buildup of indoor air pollutants.

Since most people spend 90 percent of their time indoors, this can be a significant problem if the air inside your South Carolina home is two to five times more polluted than outside air, which is common. Our Coastal Air + Refrigeration team wants to help you understand the risks of indoor air pollution as well as steps you can take to reduce it.

Negative Effects

According to the US Environmental Protection Agency (EPA) , indoor air pollutants can contribute to a host of short- and long-term effects. Because typical symptoms can be mistaken for allergies, an illness, stress, or many other causes, it’s easy to overlook indoor air quality as the main culprit.

Possible short-term effects and resulting symptoms of indoor air pollution include coughing, sneezing, itchy eyes, fatigue, dizziness, headaches, sore throat, and respiratory congestion. In addition, poor indoor air quality can make some existing illnesses worse.

For instance, if you suffer from asthma, heart disease, chronic lung illness, or other infections, indoor air pollution may exacerbate your symptoms.

Certain indoor air pollutants can cause additional serious illnesses or even death. Secondhand smoke and radon cause lung cancer, and carbon monoxide poisoning can silently kill unaware residents.

Common Indoor Air Pollutants

Daily living contributes to a great deal of indoor air pollutants. Dust, dirt, pollen, and mold are common in just about every home. In addition, pet dander and hair, smoke, and chemicals from common cleaning products can contribute more gas and particles to the indoor air. During cold and flu season, you may add bacteria and viruses to the mix.

If your home has inadequate ventilation, you won’t be able to sufficiently exchange outside and inside air regularly, which can lead to the buildup of indoor air pollutants. Failing to maintain your heating, ventilation, and air conditioning (HVAC) system in a suitable manner can also lead to indoor air problems.

For example, a clogged air filter can no longer trap more particles as they move through your system. An antiquated HVAC system can also introduce further serious problems like incomplete combustion and gas leaks.

Solutions to Improve Air Quality

As a homeowner, it’s understandable to be concerned about your indoor air quality. You can take several steps to improve your air quality right now.

First, replace and maintain the air filters in your HVAC system regularly. If you have family members who suffer from allergies or asthma, consider using high-efficiency particulate air (HEPA) filters that can remove very small particles which often trigger reactions.

Second, have an HVAC professional clean, inspect, and tune-up your heating and cooling equipment twice a year. Our trained technicians at Coastal Air will ensure no dangerous gas leaks exist and all your fuel-burning appliances have adequate ventilation. We will also provide safety checks on all your equipment.

Be sure you take extra precautions when you are cleaning with chemicals or embark on home improvement projects such as construction or painting. Your working area should be well ventilated during and immediately after the work is completed.

Consider investing in a humidifier and/or dehumidifier to help keep your home at an optimal humidity level. This will help discourage mold growth and keep your home more comfortable in all seasons. Be sure to clean this equipment according to the manufacturers’ recommendations to prevent buildup of pathogens and to keep your warranty intact.

If you’re a smoker, take your habit outdoors to prevent secondhand smoke buildup inside, and be sure to test for radon in your basement every two to five years. Install a carbon monoxide detector on every floor of your home, and don’t try to remove asbestos yourself.

Finally, keep your home clean using a HEPA vacuum and wash your bedding, curtains, and other household items regularly.

When Do I Know It’s Time to Buy a New Furnace?

It’s easy to moan when you decide that a major appliance or home system needs replacing. After all, these are expensive investments and probably not your favorite way to spend your hard-earned money. Unfortunately, there’s often not a clear-cut message, short of an appliance completely breaking down, that definitively indicates it’s time to buy a new model.

If you’re struggling with the question of whether or not to buy a new furnace in Myrtle Beach, our professionals are here to help. Our Coastal Air + Refrigeration team has years of experience with a wide selection of furnace makes and models. Here are some warning signs it may be time to start saving for a new furnace.

Your Furnace Is Getting Long in the Tooth

Yes, age gets all of us, doesn’t it? Furnaces are typically built to last about 15 to 20 years with regular usage and maintenance. Obviously, if you find yourself away on business trips or spend the winters in a warmer climate, the life span of your heating system may exceed that range. On the other hand, if you and your family are downright homebodies in a geographic location with longer winters, you may be replacing your furnace more frequently.

However, if you have an older furnace, it’s definitely one sign that you may want to consider buying a new one sooner rather than later. At the very least, invest the time to do some research so you don’t have to be pressured into a snap decision if your older heating system suddenly gives up the ghost.

You Find Yourself Cold Even With the Heat On

Heat is expensive, and if you’re paying for it, you certainly want to be comfortable. It’s understandable if your home is on the cooler side, because you’re trying to conserve energy by keeping your thermostat low. However, if you are choosing an average heating temperature that used to be comfortable and you suddenly find your home cold or unevenly heated, it may signal a problem.

In some cases, repairs and maintenance can resolve that issue. However, this may be a sign, in combination with the others in this article, which can show you that your furnace may not be doing as well as it used to do.

Your Bills Keep Getting Higher

If your energy bills suddenly take a big turn upward, check out your utility rates and consider your current South Carolina weather compared to past years first. If these items have remained relatively constant, you may want to blame your furnace.

Older furnaces are notoriously inefficient, especially when compared with the newest models. Check out ENERGY STAR® ratings of the newest models to learn what you can gain in terms of efficiency.

Are you finding yourself calling your furnace repair professional more than once a year? Repair calls can build up and be a significant investment if you’re continually replacing parts of an old furnace.

Remember that even though you’ll have to spend a significant amount of money on a brand-new furnace and installation, you’ll be saving money on an ongoing basis in lower utility bills—and hopefully eliminating repair bills in the foreseeable future. Be sure to consider that in your decision equation.

You Notice Unusual Behavior

By being aware of the typical sounds, looks, and smells of your furnace, you can be clued in more quickly if something isn’t quite right. Listen for grinding, squeaking, or banging noises coming from your furnace or be aware of unusual odors. The smell of rotten eggs can indicate a dangerous carbon monoxide leak and should be reported immediately for you and your family’s safety.

There’s a Drop in Air Quality

If you notice your home begins to feel dustier or your indoor air quality seems to be deteriorating, this can indicate a furnace problem. Besides providing heat to your home, a furnace should also help stabilize air quality.

In some cases, you may need a humidifier in the dry winter months or an air purifier if you’re addressing allergy or asthma problems. However, checking into your furnace is another avenue to take as well.

What is a Heat Pump?

Fri, 10 Jan 2020 14:55:00 GMT

A heat pump is a heating, ventilation, and air conditioning (HVAC) system that transfers heat from one place to another, from inside to outside or from outside to inside. In the winter a heat pump works like a heater, extracting heat energy from outside and transferring it inside—instead of generating its own heat like a furnace. In the summer the process reverses, and it removes heat from your home and transfers it outside like an air conditioner .

At Coastal Air + Refrigeration, we would love to talk to you if you need service or maintenance on your current system or if you are considering installing one. Many of your South Carolina neighbors are already enjoying the versatility and energy efficiency of their systems, making it a popular option here in the Myrtle Beach area.

The Differences Between Heat Pumps

There are many different names and types of heat pumps, but they can all be categorized as one of three different types: air source, water source, or geothermal.

Air Source

An air source heat pump (ASHP) transfers energy in the air from one place to another. It uses an outdoor heat exchanger coil to extract heat from the air and an indoor heat exchanger coil to transfer the heat into air ducts, radiators, or a hot water tank. This process can also be reversed, so it may be used as an air conditioner as well.

Water Source

A water source heat pump (WSHP) operates similarly to the air source but uses water instead of air to transfer heat. These types of pumps are not available to everyone because of the resources needed. However, if you live near a well, lake, or other natural resource, this can be a viable option.

A water source heat pump cycles water through a series of pipes laid out in water. As the water cycles, it collects the heat and transfers that energy into your home. Again, this process reverses in the summer and carries heat out of your home by way of the water in the pipes.

Geothermal

A geothermal heat pump is also called a ground source heat pump (GSHP). In this system, the pump uses the earth as its heat source.

Conceptually, a geothermal heat pump is the same as an air source or water source heat pump and is a popular heat pump system. According to the US Department of Energy (DOE) , millions of geothermal heat pumps are heating and cooling homes and businesses across the world, including all 50 states.

There are two different methods for its installation:

Horizontal ground-coupled system—a horizontal ground-coupled system buries horizontal piping four feet or more under the ground and circulates a fluid, like antifreeze or water, through it.
Vertical ground-coupled system—a vertical ground-coupled system has the same process as its horizontal counterpart, but the pipes are buried vertically.
