Hurricane Season and Your AC in Fort Lauderdale, FL: Before, During, and After the Storm

BW Air Conditioning

Every Broward County homeowner knows the drill by early September: shutters, water, batteries, gas. The air conditioner usually gets forgotten — right up until the power comes back and it will not start. Before a storm, secure and clear the outdoor unit and shut the system down at the thermostat and the breaker once tropical-storm-force winds are forecast; afterward, do not turn it back on until it has been inspected for flood or debris damage. Here is the full checklist for a Fort Lauderdale home.

Why September Matters Most

The Atlantic hurricane season runs June 1 through November 30, but the busiest stretch is mid-August through mid-October — which is exactly when your AC is also working its hardest. Even in a quieter-than-average year, it only takes one storm. The National Hurricane Center publishes tropical outlooks up to seven days ahead, and Broward County's official hurricane site carries evacuation zones, shelter status, and local alerts. Use both — and give yourself more than 24 hours of lead time on the AC steps below.

Before the Storm

Confirm the condenser is anchored. Your outdoor unit should be strapped or bolted to its pad with hurricane tie-downs, not simply resting on it. If you are not sure, ask during your next service visit — it is a quick thing to check and an expensive thing to discover afterward.
Clear everything loose within about 20 feet. Patio furniture, planters, decorative rock, umbrellas, and yard tools all become projectiles. The coil fins on a condenser dent easily, and a dented coil never cools the same again.
Trim back branches and secure the fence line. Trees near the unit are the most common source of post-storm condenser damage in South Florida yards.
Photograph the system. A few clear photos of the condenser, the air handler, and the model and serial plates make any future insurance claim far easier.
Get a pre-season tune-up. Going into peak season with a clean coil, a clear condensate drain, and healthy electrical connections means fewer failures when the grid comes back with a surge.
Pre-cool the house. Drop the thermostat a few degrees in the hours before landfall so the home stays livable longer if power goes out.

A pre-storm visit is really just a well-timed tune-up — our guide to professional AC maintenance covers what a real one includes.

During the Storm

Once tropical-storm-force winds are in the forecast, shut the system down at the thermostat and then at the breaker. This matters more than people expect. Utility power during a storm is unstable, and a brownout or a surge on restoration can destroy a compressor or a control board on a system that was left energized. Leave it off until you have looked things over in daylight.

After the Storm

The instinct is to flip everything back on the moment the lights return. Resist it, and walk the checklist first:

Look for standing water. If the condenser was submerged — even briefly — do not power it on. Water in the electrical compartment or compressor is a repair, sometimes a replacement, and never a do-it-yourself restart.
Check for debris and impact damage. Bent fins, a shifted cabinet, a dented top grille, or a fan that will not spin freely all mean stop.
Clear leaves and branches from around the unit before restarting, so the coil can actually breathe.
Rinse off salt spray. Coastal storms drive salt water well inland; a fresh-water rinse of the outdoor coil limits corrosion damage.
Listen on restart. Grinding, buzzing, repeated breaker trips, or warm air are all reasons to shut it back down and call.

If your system will not restart and the house is heating up fast, that is the moment for emergency AC repair rather than a wait-and-see. If the damage turns out to be structural, our breakdown of repair versus replacement will help you decide what makes sense.

Frequently Asked Questions

Should I cover my AC unit during a hurricane?

A cover will not stop wind-driven debris and can turn into a sail or trap moisture against the cabinet. Anchoring the unit, clearing the area around it, and killing the power are far more effective than covering it.

Should I turn my AC off at the breaker before a storm?

Yes. Shut it down at the thermostat first, then at the breaker, once tropical-storm-force winds are forecast. That protects the compressor and control board from brownouts during the storm and from the surge when power is restored.

My AC was underwater. Can it be saved?

Sometimes, but never by powering it on to find out. Flood water gets into the electrical compartment, the contactor, and the compressor windings. A technician needs to inspect and test it first — a restart attempt can turn a repair into a replacement.

How soon after power returns can I run the AC?

After you have visually inspected the outdoor unit for water and debris damage and cleared the area around it. If everything looks intact, restore the breaker, wait a few minutes, then turn the thermostat on and listen carefully to the startup.

Does homeowners insurance cover hurricane damage to an AC?

It depends on your policy, and flood damage is usually handled separately from wind damage. Photograph the equipment before the season and again after any damage, keep your service records, and check with your carrier — documentation is what makes those claims go smoothly.
