Why hurricane prep protects your HVAC
Hurricane season on the Space Coast runs June 1 through November 30, and the two biggest threats to your AC are power instability and flying or rising water. A few minutes of prep before the storm can be the difference between flipping the breaker back on afterward and replacing a compressor.
This checklist focuses on the homeowner-safe steps. For the wider storm-season plan — generators, water heaters, and plumbing — see our hurricane & storm prep guide.
Step-by-step: protecting your HVAC before a storm
Work through these in order as a storm approaches. Each one is safe for a homeowner to do without opening the sealed system.
-
Cool the house down early
Before the storm arrives and you lose power, run your AC to pre-cool the home a few degrees lower than usual. A well-cooled, closed-up house holds comfortable temperatures longer once the electricity goes out.
-
Turn the system off at the thermostat and breaker
Once the worst of the storm is near, switch the AC off at the thermostat, then shut off the breakers for the air handler and condenser. Powering down protects the system from damaging power surges and brownouts when the grid goes unstable.
-
Clear the area around the outdoor unit
Remove loose items, potted plants, patio furniture, and yard debris near the condenser so they can't become projectiles that dent the coil or damage the cabinet. Trim back branches that could fall on the unit.
-
Strap or secure the condenser if you can
Many Florida units sit on hurricane pads with tie-down straps or brackets. Confirm yours is anchored. If it isn't and there's time, ask a professional about a tie-down kit — don't try to lift or move the unit yourself.
-
Do NOT cover the unit while it's running, and skip plastic wrap
Covering a running unit causes overheating, and wrapping it in plastic traps moisture that promotes corrosion. If you want protection from debris, use only a manufacturer-approved cover and only after the system is powered off.
-
After the storm, inspect before restarting
Once power is restored, look the outdoor unit over for flooding, debris, dents, exposed wiring, or shifting. If the unit was submerged or struck, do NOT turn it on — water and storm damage can destroy the compressor and create a shock hazard.
-
Wait and restore power in order
If the unit looks intact and dry, wait a few minutes after power returns to let voltage stabilize, then switch the breakers back on before the thermostat. If anything looks wrong — or it was flooded — leave it off and call a licensed technician.
Safety first
Stick to the homeowner-safe steps above. Don't open the sealed refrigerant system or electrical panels, don't move the condenser yourself, and never touch a unit that's been flooded or has exposed wiring. When in doubt, power it off and call a professional.
After the storm: restart safely
The temptation after a long, hot outage is to flip everything back on at once. Slow down — restoring power the right way prevents a damaged unit from becoming a destroyed one.
- Inspect the outdoor unit for flooding, debris, dents, and exposed wiring.
- If it was submerged or struck, leave it off and call a licensed technician.
- If it looks intact, wait a few minutes after power returns, then restore the breakers before the thermostat.
- Listen for unusual noises and watch for weak cooling — both warrant a post-storm check.
Coastal homes: rinse off the salt
Storm surge and wind-driven spray coat coastal units in extra salt. Once it's safe and the power is off, a gentle fresh-water coil rinse helps — and so does a post-season tune-up. See salt-air corrosion & your coastal AC.
