- Short Answer: When your AC runs but the house stays warm, the usual causes are low refrigerant from a leak, a dirty or salt-corroded coil, a failing compressor, or a frozen coil. Near the Myrtle Beach coast, salt air makes coil and electrical problems more common than they are inland.
Most of the time it comes down to a handful of things. Refrigerant does not get used up, so if it is low, there is a leak somewhere that needs to be found and fixed, not just topped off. A coil caked with dirt or eaten by salt cannot move heat the way it should. A tired compressor or a frozen indoor coil will leave you with air moving but no cool. We check the simple, less expensive causes first and show you what we find before we recommend anything bigger. That is part of how we fix it right the first time, instead of guessing. If your unit sits within a mile of the water, see how salt air affects coastal AC systems for why these problems show up sooner here.
When your AC quits in the Conway heat, we get you cool again. Coastal Air Plus repairs central air, heat pumps, and ductless systems across Conway, from the older homes in the Historic District to the new builds along Highway 501 and the rentals near Coastal Carolina University. We diagnose, explain your options, and get your okay before any work. Call (843) 238-3838.

- Short Answer: Yes. We work with landlords and property managers on the student rentals around CCU and Red Hill, including homes with several units. We can get systems checked and repaired between leases so a tenant is not left in the heat.
Rental owners near the university often manage more than one property, and a failed AC in August is a fast way to lose a tenant's goodwill. We will give you an honest estimate, do the work without upselling, and keep your units running season after season. Creating lasting relationships with Conway property owners is exactly the kind of work we are built for. Set up recurring visits through our VIP Maintenance Club so the checks happen before the heat does.

- Short Answer: If your property is in a Conway Special Flood Hazard Area, often yes. The City requires structures and equipment to be elevated, with a minimum of 2 feet above base flood elevation in the flood zone, stricter than the coastal towns, given the Waccamaw River flood history.
Conway sits on the Waccamaw River, and after Hurricane Florence the city made flood readiness a priority. Conway runs its own permitting, so a replacement here is permitted and inspected by the City of Conway Building Department (the authority), not the county. In a Special Flood Hazard Area, equipment must be elevated to the city minimum of 2 feet above base flood elevation (the code), under the City's Flood Damage Prevention Ordinance and the National Flood Insurance Program (the rule). We handle the permit, the elevation, and the inspection. A new Trane system meets the 14.3 SEER2 minimum for our region, refrigerant work is done by technicians certified under EPA Section 608, and a high-efficiency heat pump may qualify for a Santee Cooper rebate when a Trade Ally installs it, which we are.
- Short Answer: Yes. When your AC goes out in the summer heat, we prioritize emergencies and work nights and weekends across Conway. During peak season it can take a little longer, and we will be straight with you about timing when you call.
A hot house with kids, older family members, or pets is not something we ask you to sit on. We move emergencies to the front of the line and give you an honest window rather than a promise we cannot keep. A simple call starts it. Request service or call (843) 238-3838.
A few things to check before you call
- Set the thermostat to cool and check the batteries.
- Make sure the AC breaker has not tripped.
- Check the air filter. A clogged filter is a common, easy fix you can do yourself.
If those look fine and you are still warm, that is when to call us.
Do I need a permit to replace my AC, and what about the coast?
- Short Answer: Yes. A system replacement needs a mechanical permit, and the authority depends on your address (your city, or the county if unincorporated). Near the water, flood-zone rules may require the new equipment raised above the flood line, and coastal salt means coastal-rated equipment is worth it.
We pull the mechanical permit for your replacement and have the work inspected, through whichever authority covers your address. On the barrier islands and along the marsh, FEMA flood rules can require the condenser raised on a stand above the expected flood line, and the steady salt air rewards corrosion-resistant, coastal-rated equipment that lasts longer near the ocean. Inland, salt is barely a factor and the focus is humidity and efficiency. We size the equipment and the install to where you actually live, which is the same block-by-block read we bring to every Charleston County, Berkeley County, and Dorchester County job.
How much does AC repair cost in Conway?
- Short Answer: Most AC repairs in the Conway area run about $150 to $600 after a service call to diagnose the problem. Bigger jobs like a compressor or coil cost more. We give you the estimate before we start, so there are no surprises.
Typical area ranges to help you plan, not a quote. Your exact price depends on the part and your system, and we confirm it after we diagnose the unit.
Older R-22 systems can cost more on the refrigerant side because that refrigerant is being phased out. We will always tell you up front when that is a factor.

Should I repair or replace my AC?
- Short Answer: Repair a newer system with a small electrical fix. Replace when it is past 10 to 15 years, runs old R-22 refrigerant, the compressor has failed out of warranty, or a repair tops about half a new system. Conway's older homes often have aging units where that decision comes up.
A lot of older Conway homes still run R-22, which is no longer made and keeps getting pricier to service, so on those we will walk you through whether another repair is worth it. We are not better than the next company, just different, in that we would rather keep a sound system going than sell you one you do not need yet.
