Hurricane Season Starts in 30 Days: Protect Your HVAC Investment Now

Get a Pre-Season Inspection

The most important thing you can do before hurricane season is confirm your system is in good working order. A storm knocks out power for days. When power comes back, you want your system to fire up and run. If there was already an underlying problem, the stress of restart after a power outage can push a marginal system over the edge.

Our pre-hurricane inspection covers the full system.

• Our techs take their time with every visit: electrical connections, capacitors, contactors, refrigerant levels, and overall operational health.
• We also check that your disconnect box is sealed properly against water intrusion. Schedule this now.
• Once a storm is in the forecast, our schedule fills up fast and pre-storm visits become impossible.

The Tarp Mistake: Do Not Cover Your Outdoor Unit

This is the most common mistake we see every hurricane season. Homeowners assume that wrapping the outdoor unit in a tarp protects it. It does not. Tarps trap moisture against the unit, accelerate corrosion on the coils and cabinet, and can be pulled into the unit by wind, causing damage to the fan blades and condenser coil.

Your outdoor unit is designed to handle rain and wind. If you want to understand what coastal conditions specifically do to HVAC equipment, our post on how salt air damages your AC unit covers the full picture. And if you have not yet scheduled your spring AC tune-up on the Grand Strand, that is the first call to make before hurricane season begins. What it needs before a storm is to have loose debris cleared away from the area around it so nothing becomes a projectile. That is it. Do not cover it.

Document Your Equipment for Insurance

Before storm season, photograph your outdoor unit, your air handler, and any other HVAC equipment. Record the model and serial numbers. Store this documentation somewhere accessible outside your home, either in cloud storage or with someone who lives inland.

If your equipment is damaged in a storm, having documentation of the pre-storm condition and specifications significantly speeds up the insurance claims process. This takes ten minutes and matters a great deal if you ever need it.

What to Do With Your HVAC Before Evacuating

If a storm is approaching and you are evacuating, here is the correct procedure for your HVAC system.

• Set the thermostat to off, not just to a high temperature. You want the system completely stopped, not running, and potentially overloading when power fluctuates.
• Turn off the breaker for your AC system at the main panel. This protects the equipment from power surges when utility power is restored, which often comes back unevenly. Surge damage is one of the most common post-storm HVAC issues we see, and turning off the breaker before you leave prevents most of it.
• If you have a whole-house generator, confirm it is properly sized for your HVAC load before storm season, not when a storm is 48 hours out. An undersized generator can damage your system when it attempts to start under load.

Protecting Indoor Equipment From Water Intrusion

In a significant storm, water can enter your home through windows, doors, and roof penetrations. Your air handler, typically located in a closet, attic, or utility room, is vulnerable if water gets into those spaces.

Before storm season, check that the area around your air handler has no existing water intrusion paths: gaps around ductwork penetrations, unsealed attic access points, or cracked condensate drain lines. These are small issues in normal conditions. In a storm, they become pathways for serious water damage.

Post-Storm Restart: Do Not Rush

After a storm passes and power is restored, wait at least 30 minutes before restarting your HVAC system. This allows the refrigerant to settle and protects the compressor from a hard start with potentially uneven refrigerant pressure.

If your outdoor unit had any water contact above the base, or if you see any physical damage to the unit, do not attempt to restart it. Call us first. Running a damaged system can turn a repairable situation into a replacement.

Generator Planning: Do It Now

If you are considering a whole-house generator, or if you have one and are not sure it is properly integrated with your HVAC system, now is the time to address it. Generator work during or after a storm is difficult, expensive, and often impossible due to demand. If you want backup power for your HVAC, get it sorted in May.

We work with homeowners on generator compatibility assessments as part of pre-hurricane preparation. We can tell you what your system requires and whether your current generator is sized appropriately.

Schedule Before the Rush

Every year we see the same pattern. A storm forms in the Atlantic in late June or July, the forecast track turns toward South Carolina, and suddenly every HVAC company in the region is fully booked for inspections, repairs, and generator assessments. Homeowners who waited are out of luck.

You have 30 days. That is enough time to do everything on this list properly. We work through this with each homeowner one at a time. Schedule the inspection, document your equipment, check your breaker procedure, and get your generator situation sorted. Then you can watch the season unfold without the anxiety of knowing you are unprepared.

At Coastal Air Plus, creating lasting relationships is what we are all about. We have watched hurricanes come and go on this coast for over 75 years. We know what these systems go through and what preparation actually makes a difference. You will not be oversold. We will be straight with you about what your system actually needs and nothing it does not.
