After a hurricane hits, checking your HVAC system for safety should be a top priority—especially if your area experienced flooding or severe winds.
Even if your unit looks fine on the surface, hidden issues could compromise its performance or pose serious health and safety risks. Here’s what you need to know to be sure your HVAC is safe to use after a storm.
-
Clear Debris and Inspect for Damage
Start by inspecting your outdoor unit for any visible damage. Hurricanes can blow leaves, twigs, and all kinds of other debris into the system, which may block airflow or damage components.
Clear away any debris around the unit to ensure proper ventilation. If you notice any dents, exposed wires, or parts that seem out of place, avoid turning it on and call a specialist right away.
-
Dry Out Any Water Exposure
If your HVAC was exposed to floodwaters or heavy rain, you’ll need to dry out the surrounding area. Water damage can lead to electrical hazards, mold growth, and system malfunctions. For indoor units, use fans or dehumidifiers to remove moisture. If your outdoor unit was submerged, you’ll need to have it professionally inspected and likely to be fully replaced.
Even if your HVAC looks fine after a hurricane, hidden issues like
water damage or debris can pose serious health and safety risks.
Don’t turn it on without a thorough inspection!
-
Replace Filters and Look for Mold
Even if your HVAC system wasn’t submerged, moisture from the storm can still dampen filters and cause mold growth. Replace all filters to prevent contaminants from circulating through your home. While replacing the filters, check vent covers and duct interiors for any signs of mold or mildew, such as white or black spots.
-
Test Carbon Monoxide Detectors and Monitor System Performance
Make sure your carbon monoxide detectors are working correctly, especially if your HVAC system uses gas. This is a crucial safety check to prevent harmful gas buildup if the system isn’t functioning properly. Once you’re confident that everything is clear, turn on the HVAC and pay close attention to its performance. If it’s not cooling or heating as it should, or if you notice unusual sounds or smells, turn it off and call in the pros.
Why Should You Check Your HVAC After a Hurricane?
Water and debris can cause extensive damage to your HVAC, leading to costly repairs or even system replacement. Floodwater can contaminate your system with dirt, mold, and bacteria, while debris can clog the unit, hindering its performance. In severe cases, electrical components may be compromised, posing a risk of fire or electrical shock.
