Hurricane-Season AC Prep Checklist
June 1 is the real deadline in Tampa. A $15,000 AC system is one of the most storm-vulnerable things you own — here’s how to protect it before, during, and after a hurricane.
Calls connect you with a licensed HVAC partner. By calling you agree to be contacted about your project.
Before June: the pre-season tune-up
- Schedule a professional tune-up in April or May — before every tech in Tampa is booked solid. Clean coils, verified refrigerant charge, tightened electrical connections, and a cleared drain line.
- Install or verify surge protection. A whole-house surge protector plus an HVAC-specific suppressor at the disconnect is the best money you can spend on a Florida AC.
- Check the condenser anchoring. The outdoor unit should be bolted/strapped to its concrete pad per Florida Building Code. If it rocks when you push it, it’s not storm-ready.
- Clear the area. Remove anything within 2–3 feet that wind could throw into the coil fins — patio furniture, toys, loose pavers.
- Trim overhanging branches above and around the unit.
- Test your thermostat’s batteries and know where the outdoor disconnect is.
48 hours before landfall
- Run the AC a degree or two cooler than normal to pre-cool the house — thermal mass buys you hours of comfort after the power dies.
- Turn the thermostat to OFF as the storm approaches (or use the outdoor disconnect). Surges during landfall are what kill compressors.
- Move patio items inside; confirm nothing loose remains near the condenser.
- Do NOT cover the outdoor unit with a tarp — wind will shred it and the debris damages the fins.
After the storm: restart the right way
- Inspect the outdoor unit from a safe distance: standing water, displaced position, debris embedded in fins, damaged electrical whip.
- Wait for stable utility power — then wait another 30 minutes.
- Restore power at the disconnect, then set the thermostat to cool.
- If the breaker trips, you hear grinding, or smell burning — shut it down and call a licensed tech. Post-storm surge damage is extremely common and usually repairable if caught before the compressor cooks itself.
- Photograph any physical damage immediately for insurance — wind damage is a covered peril under most Florida policies (minus your hurricane deductible).
The generator question
Running a central AC on a portable generator is possible but tricky: the startup surge of a compressor can be 3–5× its running watts, and “dirty” generator power can damage modern variable-speed electronics. If you plan on it, have an electrician install a proper transfer switch and size the generator for the locked-rotor amps on your unit’s nameplate — don’t guess. A soft-start kit (~$300–$500 installed) dramatically reduces startup surge and is worth discussing with your tech either way.
Get storm-ready before June
Book a pre-season tune-up and surge protection check with a licensed Tampa HVAC contractor — April and May slots go fast.
Hurricane prep FAQs
Should I turn off my AC before a hurricane?
Yes — turn the thermostat to OFF (not just raised) before the storm hits, and flip the outdoor disconnect/breaker if you're comfortable doing so. This protects the compressor and electronics from the surges and brownouts that accompany landfall. Leave it off until power is stable after the storm.
How do I secure my outdoor AC unit for a hurricane?
Most Florida code-compliant installs already have the condenser anchored to its pad with hurricane straps or bolts — check yours before June. Clear debris and loose objects from around the unit, trim overhanging branches, and never wrap the unit in a tarp or cover during the storm; trapped wind turns covers into sails.
When can I turn the AC back on after a power outage?
Wait until utility power is stable — not flickering — then wait 30+ minutes more. Power restoration often comes with surges as the grid rebalances. Turn the thermostat back on and listen: normal startup sounds mean you're fine. If the breaker trips immediately or you smell burning, leave it off and call a tech.
Does homeowner's insurance cover hurricane damage to my AC?
Physical damage from wind or flying debris is typically a covered peril, minus your hurricane deductible. Electrical damage from power surges is often covered too, but insurers may argue wear-and-tear — documentation of the storm's timing helps. Flood damage to the unit is NOT covered by standard homeowner's policies; that's separate flood insurance.
