Hurricane Season HVAC Prep.
Baldwin County sits on the working end of the Gulf. Hurricane Sally (September 16, 2020) knocked out power countywide — and storm-stressed HVAC systems can surface damage months later. Here's how to prep the system before a storm, ride it out, and restart safely after.
What a hurricane actually does to an HVAC system.
Four separate mechanisms, in rough order of frequency: power events (surges and brownouts as the grid fails and restarts, which kill capacitors, control boards, and — worst case — compressors), wind and debris (bent coil fins, punctured refrigerant lines, units shifted off their pads), water (storm surge and flooding that soak electrical components, which must never be re-energized without inspection), and the slow one — salt and moisture driven deep into equipment by the storm, showing up as corrosion failures months later.
The pattern matters because the cheap failures are preventable and the expensive ones are detectable early. That's the logic of the checklist below — and of the Hurricane Watch and Hurricane Warning condition pages, which cover the hours when an alert is actually in effect.
The Pre-Season Checklist.
Do these once, in late spring, and the storm-week list gets short.
- Verify the outdoor unit is anchored — hurricane-zone code calls for the condenser to be strapped or bolted to its pad; older installs and re-poured pads are the common gaps
- Clear the debris field — anything within throwing distance of the condenser (limbs, furniture, loose fencing) becomes coil-fin shrapnel at 100+ mph
- Add HVAC surge protection — a hard-wired surge protector at the disconnect is cheap insurance for control boards and compressors against grid-restart spikes
- Get the system inspected while parts are calm — a spring tune-up catches marginal capacitors and corroded connections that storm stress finishes off
- Know your shutoffs — find the breaker and the outdoor disconnect now, not by flashlight
- If your home is FORTIFIED, note it — roof and attic penetrations for HVAC work must respect the designation; tell any contractor before work starts
When a watch goes up.
- 01Pre-cool the house — run the AC hard while power is reliable; a house cooled to 70°F buys comfortable hours after an outage
- 02Photograph the equipment — outdoor unit, indoor unit, thermostat readout; before-and-after photos are what insurance adjusters ask for
- 03Shut down before landfall — thermostat off, then the breaker; a system that isn't energized can't take a surge or try to run underwater
- 04Do not re-energize until the unit passes the three checks in the FAQ below — shifted, debris, flood water
After the storm, damage can hide. A system that restarts fine but was hit by surge or driven salt spray can fail weeks or months later — post-Sally era damage in Baldwin County could still turn up years after the storm. If your system took any of the four hits above, a post-storm inspection is cheaper than the failure it predicts. Call (251) 300-9817.
Hurricane Season HVAC — Frequently Asked Questions
Should I cover or strap my outdoor AC unit before a hurricane?
Strapping matters more than covering. Modern condensers are built to shed rain; the storm risks are wind (unanchored units shifting or tipping), flying debris, and storm surge or flood water. Baldwin County installs are anchored to code for our wind zone, but older pads and DIY-relocated units are worth checking before June. A cover helps against debris only if it's secured — a loose cover becomes a sail. Never run the system with a cover on.Should I turn my AC off during the storm?
When the storm arrives — yes, at the breaker. The two big electrical risks are surge as the grid fails and restarts, and a compressor trying to run while wind-driven rain or flood water is in the unit. Cool the house down ahead of landfall, then shut the system off at the thermostat and the breaker before conditions get dangerous.When is it safe to turn the AC back on after a storm?
After you've confirmed three things: the outdoor unit hasn't shifted on its pad, no debris is lodged in or against it, and — most importantly — it never sat in flood water. If water reached the unit, do not energize it; flood-soaked electrical components and controls can fail dangerously, and that's a professional inspection first. If all three check out, restore the breaker, wait several minutes for the crankcase heater on newer units, and start the system normally. Anything smells burnt, breakers re-trip, or the unit hums without starting: leave it off and call.Does homeowner's insurance cover hurricane damage to HVAC equipment?
Frequently yes for wind and debris damage, with flood damage depending on separate flood coverage — but policies differ and we're not insurance adjusters. What we provide is the documentation: a written post-storm diagnosis of what failed and why, which is what an adjuster needs. Many Baldwin County homes also carry FORTIFIED designations that interact with wind coverage — worth knowing before the season starts.Do you answer during and after storms?
The 24/7 emergency line — (251) 300-9817 — is answered live when we can, storms included. Crews roll when conditions are safe; no contractor should promise you an arrival time while a hurricane is overhead, and we won't. Cool Club members get priority scheduling, which matters most in exactly these weeks.
Schedule the Pre-Season Check.
Anchoring, electrical connections, surge protection options, and a written report of what a storm would find. Form requests are confirmed by phone during weekday office hours (8 AM–4 PM); for emergencies, call any hour.
