Your AC after a hurricane or flood in Cape Coral

First: leave it off

Hurricane Ian made landfall on Cayo Costa on September 28, 2022, as a Category 4 hurricane with winds near 150 mph. Peak surge on Fort Myers Beach reached 10 to 15 feet above ground, and the National Hurricane Center counted at least 52,514 structures impacted in Lee County, 5,369 of them destroyed. Two years later Milton came ashore at Siesta Key on October 9, 2024, as a Category 3 hurricane with winds near 115 mph. A lot of Cape Coral condensers sat in water for one or both.

FEMA's flood guidance says to turn off the main power and not to use gas appliances until a professional inspects them. No government source I found says "do not run a flooded AC" in those words. That is my advice anyway: leave it off until a licensed technician has looked at it. The outdoor unit has a compressor and a control board sitting a few inches off the pad. The air handler in a garage or closet has a blower motor and electronics at floor level. Turning power back on to wet or salt-crusted electrical parts is how a repairable situation becomes a dangerous one.

• Switch off the AC breakers at the panel, both the outdoor unit and the air handler.
• Do not reset the thermostat to "see if it works."
• If the house took water, the duct system and insulation may be wet too. That is a mold problem on a timer in this climate.

Inspection, and why replace usually beats repair

AHRI advises replacing flood-damaged heating and cooling equipment rather than repairing it, and having a qualified technician inspect it. Saltwater is the reason this matters so much here. It corrodes coils and electrical parts, and some of that damage shows up weeks later, after the unit seemed fine.

Ask the technician to write down what they found: which components were submerged and what they recommend. That document is what your insurer will want. If a technician tells you a submerged system just needs a rinse and a new capacitor, I would get a second opinion, and I would also get one if a system that never saw water is suddenly "a total loss." Our repair or replace guide covers how to think about the price.

Photos for insurance

• Photograph the outdoor unit from all sides before anything is moved, with the water line or debris line visible.
• Photograph the air handler, the floor around it and any water marks on walls nearby.
• Photograph the data plate on each unit (model and serial number).
• Keep the technician's written findings and every invoice.
• Do not throw out damaged equipment until your adjuster says you can.

Wind and flood are often covered by different policies. Ask your agent which one applies to the AC before you sign a replacement contract.

Generators and central AC

The CDC's rule is simple: never run a generator inside the home or garage, even with the doors and windows open. Run it outdoors, more than 20 feet from windows, doors and vents. The garage is exactly where people want to put it to keep it from being stolen. Don't.

Whether a portable generator can run your central AC depends on the generator's size and how much power the system needs to start, which is higher than what it needs to keep running. I can't tell you from here. Ask a licensed electrician or HVAC professional before you try it, and never back-feed power into the house through a dryer outlet or similar setup without a proper transfer switch.

Permits for a replacement in Cape Coral

Replacing a flooded system in Cape Coral needs the city's A/C Change Out permit. Only an HVAC contractor (CAC), a mechanical contractor (CMC) or an owner-builder can apply. The city requires an HVAC Data Sheet, and depending on the property it may require a Notice of Commencement, a FEMA packet or elevation certificate, a duct layout and floodplain review. In a flood zone the new outdoor unit may need to sit higher than the old one. Ask the contractor how they will handle the elevation requirement and whether it is in the price.

Check the license yourself before you hire anyone. Our license lookup guide walks through it. If the contract is over $2,500, Florida law requires it to include the construction lien notice. Get written lien releases from anyone who sent you a Notice to Owner before each payment.

Price gouging and door-to-door contracts

Florida's price gouging law, section 501.160, covers services as well as goods. It applies in the area of a declared state of emergency, for up to 60 days under the initial declaration, and the declaration can be extended. The test is whether a price is a gross disparity from the average price in the 30 days before the declaration, unless the seller can show added costs explain it. Report it to the Florida Attorney General at 1-866-9NO-SCAM (1-866-966-7226).

If someone knocks on your door after the storm and you sign in your home, Florida's home solicitation sale law generally gives you until midnight of the third business day to cancel. The FTC's warning signs apply: "in the area", pressure to decide now, everything up front or cash only. Don't make the final payment until the work is done.

This happens here more than people think

Since 1859, 69 tropical systems have passed within 60 miles of Cape Coral, 20 of them hurricanes and 8 major hurricanes. 4 of the majors came after 2000: Charley, Wilma, Irma and Ian. FEMA has issued 19 major disaster declarations for hurricanes and tropical storms covering Lee County, 7 of them since 2017.

NOAA National Hurricane Center HURDAT2 best tracks, six-hourly positions plus landfall points, measured from central Cape Coral. Hurricane Milton made landfall on Siesta Key in 2024, about 70 miles north, outside this radius.

If you are replacing anyway, it is worth asking about a raised stand for the outdoor unit and where the air handler sits. More on local weather is on our heat and humidity data page.
