Understanding the Risk

Your AC is more vulnerable
than you think — here's why

Most homeowners protect their windows and doors. Very few protect the $8,000–$14,000 system sitting outside their home. Here's what actually damages AC units during hurricanes.

Power Surge at Restart

When utility power returns after an outage, the voltage spike can instantly burn out a compressor. This is the #1 cause of post-hurricane AC failure — and it's 100% preventable with a proper shutdown.

Flying Debris Impact

At 100+ mph winds, even small objects become projectiles. An unsecured lawn chair or branch can puncture condenser coils, bend fins, or shatter the fan assembly — damage that requires full replacement.

Flood & Storm Surge

Saltwater flooding corrodes electrical components in hours. If your outdoor unit is submerged — even briefly — the motor windings, capacitors, and contactor are almost certainly destroyed.

Refrigerant Line Damage

Wind stress on refrigerant lines — particularly where they connect to the unit — can cause hairline fractures. Running a system with a slow refrigerant leak causes compressor failure within weeks.

Extended Run After Damage

Homeowners anxious to cool down after a storm often restart AC immediately. Running a damaged system causes exponential additional damage — turning a $400 repair into a $7,000 replacement.

Indoor Unit & Ductwork

Roof damage during a storm can expose ductwork to rain. Water in ductwork breeds mold within 48 hours and can destroy the air handler. Always inspect the attic before restarting the system.

AC Checklist

Follow every step in order. Share this page with your household now — before a storm threatens.

1
Before the Storm
72–48 hours before landfall
Pre-cool your home to 68°F Critical
Run your AC on its coldest setting for several hours. The thermal mass of your furniture, walls, and floors will keep you comfortable for 24+ hours after shutdown.
Turn AC off at the breaker panel Critical
Do not just set the thermostat to off. Go to your electrical panel and flip the dedicated AC circuit breaker to OFF. This protects against power surges when power returns.
Note your AC breaker location
Write it down or photograph the panel. You'll need to find it in the dark after the storm. Label it clearly if it isn't already.
Clear the area around your outdoor unit Critical
Remove all patio furniture, potted plants, garden tools, and decorations within 20 feet. At 100mph, a clay pot becomes a missile that can destroy condenser fins.
Cover the outdoor condenser unit Important
Use a hurricane-rated AC cover or heavy-duty tarp secured with bungee cords or rope. Do NOT use plastic sheeting that can shred and get sucked into the fan. Do NOT cover if unit is on and running.
Remove window AC units Important
Window units create a structural weak point. If a window AC cannot be removed, seal around it with duct tape and board it up like the window itself.
Photograph your system for insurance Tip
Take clear photos and video of your AC system, the serial number tag, and surrounding area. Email them to yourself so you have a time-stamped record for any insurance claim.
Check your AC warranty documentation Tip
Locate your warranty documents, purchase receipts, and the AC serial/model number. Put them in a waterproof bag with your other important documents.
2
During the Storm
Landfall through all-clear
Do NOT attempt to run the AC Critical
Even if power remains on, do not run your AC during the storm. Wind-driven rain can enter the system, debris can block or damage the fan, and voltage fluctuations will fry electronics.
Keep all windows and doors sealed
If storm surge or flooding is possible, move to a higher floor. Do not open windows or doors to check on your AC unit during the storm.
Monitor your AC breaker status
If power fluctuates or you experience outages and restorations, go to the panel and confirm the AC breaker is still in the OFF position each time. Power company restorations can accidentally trip breakers.
Do not go outside to check on the unit Critical
An AC unit can be replaced. You cannot. Stay inside until the official all-clear is given by local emergency management — not just when the rain stops. The eye wall passing can create a deceptively calm period.
Note any unusual smells or sounds
Burning electrical smell, hissing, or unusual noise from your air handler could indicate a problem. Do not investigate during the storm — note it for post-storm inspection.
Use battery-powered fans for circulation
Battery-operated fans can make 85–88°F feel tolerable. Position them to move air over ice if you have it. Keep your body hydrated — heat exhaustion risk increases significantly without AC.
3
After the Storm
First 24–48 hours post-storm
Wait for official all-clear before going outside Critical
Lee and Collier County Emergency Management will issue the all-clear via radio and emergency alerts. Wait for it — downed power lines near your outdoor unit are invisible hazards.
Visually inspect the outdoor unit — do NOT touch yet Critical
Walk around the unit and look for: visible structural damage, debris packed into the unit, bent fins, crushed refrigerant lines, standing water at or above the base pan, or discoloration from impact.
Check for flooding / saltwater exposure
If your unit was submerged even partially in saltwater, do not restart it under any circumstances. Saltwater corrodes copper and aluminum components within hours. Call us for inspection first.
Inspect your attic and air handler
Check for roof damage that could have exposed ductwork to rain. Water in ductwork begins growing mold within 24–48 hours. Look for water stains on the ceiling around supply vents.
Wait 30 minutes after power is restored Critical
Utility restoration is messy — voltage swings violently for the first 15–30 minutes as the grid stabilizes. Starting your AC during this window is the #1 cause of post-hurricane compressor failure.
Remove the cover and check for trapped debris
Before restarting, remove the tarp/cover and manually check inside the unit for leaves, sticks, or small animals that may have taken shelter. A blocked fan will destroy the motor on startup.
Gently rinse the outdoor unit with fresh water Tip
Use a garden hose (not a pressure washer) to rinse salt, debris, and dirt from the condenser fins. Spray from the inside out if possible. Let it fully dry before restarting.

Expert Advice

Pro tips from our
field technicians

After servicing thousands of SWFL homes, our techs have seen everything. These are the tips that save the most systems.

The Surge Protector Rule

A $300 whole-home surge protector can save a $10,000 AC system. Install one before hurricane season — not during. Ask our team about installation at your next service visit.

The 30-Minute Rule

When power returns after a hurricane, wait at least 30 minutes before turning on any major appliance. The grid is unstable and voltage swings can destroy electronics in seconds.

Never Use a Pressure Washer

The delicate aluminum fins on your condenser coil bend at 30 PSI. A pressure washer at 1,500 PSI will destroy them. Use a garden hose with gentle pressure only.

The Salt Air Problem

Even without flooding, salt-laden hurricane winds coat condenser coils and fins with corrosive salt residue. A fresh water rinse after every major storm extends system life by years.

Don't Cover a Running Unit

Never put a cover or tarp on your AC while it's running. This traps heat, restricts airflow, and can cause immediate compressor failure. Always shut down completely first.

Pre-Register for Storm Response

After Ian, qualified HVAC techs were booked 6 weeks out. Call us now to pre-register as a storm response customer — our existing customers get 48-hour priority dispatch.

Check Your Pad & Straps

Your outdoor condenser sits on a concrete pad. Verify it's not cracked and that the hurricane tie-down straps — required by FL code since 2002 — are present and intact.

The Insurance Documentation Trick

Email a video walkthrough of your AC system to yourself before each hurricane season. The timestamp proves pre-storm condition — this single step has saved homeowners thousands in denied claims.
