In the Lowcountry, hurricane season isn’t just a possibility—it’s a reality. While most homeowners focus on stocking up on essentials, boarding windows, and reviewing evacuation routes, one vital system is often overlooked: their HVAC unit. Preparing your HVAC system before a storm hits is about more than just comfort—it’s about protecting your investment and ensuring your home is ready to bounce back once the weather clears.

In this blog, our reliable service team will discuss what Charleston area homeowners should know about getting their heating and cooling systems storm-ready.

1. Why Your HVAC Needs Hurricane Prep Too

Your HVAC system is one of your home’s most expensive and essential components. When high winds, flying debris, heavy rain, and power outages are on the horizon, your outside condenser unit and indoor equipment can become vulnerable to damage.

Failing to prepare your system correctly can lead to water damage, electrical issues, and even complete system failure, making post-storm life even more challenging than it needs to be.

2. Before the Storm: Key Prep Steps

Here are some proactive steps you can take before a storm rolls in:

Turn Off the Power

When a hurricane warning is issued, turn off your heating and air conditioning system at the thermostat and the breaker. This helps prevent electrical surges that could fry your system when power flickers or goes out.

Secure Your Outdoor Unit

Use hurricane straps or metal brackets to anchor your outdoor condenser to its concrete pad. Many newer units are installed with hurricane-rated mounting hardware, but it’s worth checking. If your unit isn’t anchored, strong winds could dislodge it—leading to major repairs.

Clear the Area

Make sure there is no outdoor furniture, yard tools, or loose branches near your HVAC unit. These can become dangerous projectiles in high winds and easily damage your system.

Cover the Unit (If Recommended)

While we usually don’t suggest covering your unit for everyday use, a breathable waterproof cover can help shield it from flying debris and flooding during a storm. Just be sure to remove the cover once the storm passes to avoid trapping moisture.

Check Drainage Around the Unit

Ensure the area around your unit drains properly. Standing water can infiltrate your system, especially during heavy rains. If the ground pools water, consider adding gravel or improving the slope to direct water away.

3. After the Storm: Inspect Before Restarting

Once the storm has passed and it’s safe to go outside, carefully look at your HVAC system before flipping the breaker back on. Look for:

  • Obvious damage to the unit, such as dents, missing panels, or disconnected wires.
  • Flooding around or inside the unit.
  • Debris inside the unit’s grill or fan blades.
  • Strange sounds or smells once restarted (if in doubt—shut it off again).

If anything looks or sounds off, don’t risk further damage. Call a certified technician to inspect your system before using it.

4. The Importance of a Pre-Storm HVAC Checkup

Your HVAC system works hard in the Lowcountry heat and humidity. Inspecting it before hurricane season gives you peace of mind that it’s working efficiently and ready to withstand rough weather.

At Prestige Heating & Air, we offer seasonal HVAC maintenance that covers everything from cleaning coils to checking refrigerant levels and inspecting electrical components. A pre-hurricane season checkup also allows us to identify vulnerabilities or recommendations for storm-proofing your system.

5. Don’t Forget About Indoor Systems

If your system includes a heat pump or air handler inside your home—especially in attics or crawlspaces—ensure these spaces are secure against water intrusion. Sealing vents, checking for roof leaks, and even using dehumidifiers can help minimize indoor damage after a storm.
