Before the Storm
Cool the house down ahead of landfall while you still have power, then set the thermostat a little higher than normal to reduce strain if power flickers. When conditions deteriorate, turn the system off at the thermostat and at the breaker. A system that is off cannot be damaged by the voltage spikes and rapid power cycling that come with a storm, which are responsible for a large share of the failures we see afterward.
Outside, clear the yard of anything that can become a projectile: furniture, potted plants, toys, loose fencing. If your condenser sits in a flood-prone spot, that is worth knowing before the season, because elevating a unit is a planned job, not a day-before job. Anchoring is not optional. Florida requires outdoor equipment to be secured, and coastal wind zones carry the strictest requirements. Worth knowing: anchoring hardware corrodes in the same salt environment as everything else, so verifying it is intact is a maintenance item rather than a one-time check at installation.
After the Storm
Do not switch the system back on the moment power returns. Walk the outdoor unit first. Look for debris packed into the fins, a shifted or tilted unit, bent refrigerant lines, or any sign the unit took on standing water. If floodwater reached the unit, leave it off and have it inspected before it ever runs again. Water in the electrical components and controls can turn a repairable unit into a fire risk.
Inside, listen during the first few minutes of operation. Grinding, buzzing, or repeated tripping of the breaker means shut it down and call. Running a damaged system compounds the damage, and after a storm is exactly when you want a small repair bill instead of a replacement.
The Insurance Angle
Photograph your equipment now, while it is healthy: the outdoor unit, the data plate with model and serial numbers, and the indoor air handler. If you ever need to file a claim, dated photos of pre-storm condition remove most of the argument. Keep your maintenance records too. A documented service history supports both claims and warranty coverage.
Quick Checklist
- Pre-cool the home, then power the system fully off before landfall
- Verify anchoring is intact, which Florida code requires and salt air degrades
- Clear the yard of projectiles and secure the condenser
- Photograph equipment and data plates before the season
- After the storm, inspect the outdoor unit before restoring power to it
- Any flood contact means professional inspection before restart

Frequently Asked Questions
Should I cover my AC unit before a hurricane?
There is an important distinction here. A temporary debris shield, installed with the power off immediately before a storm and removed immediately after, is a legitimate protective measure against flying debris. A cover left on the unit is not. Enclosing a condenser restricts the airflow it needs to reject heat and traps moisture against the metal, which accelerates corrosion rather than preventing it, and it becomes a home for rodents and insects. Never run the system with any covering in place. If you would not remove it the day the storm passes, do not install it.
My AC will not turn on after the storm. What do I check first?
Check the breaker panel and the outdoor disconnect first, since storms trip both. If those are set and the system still will not start, or it starts and trips again, stop there and schedule service. Repeated resets against a fault cause real damage.
Does homeowners insurance cover storm damage to HVAC equipment?
Wind and debris damage is commonly covered and flood damage often falls under separate flood coverage, but every policy differs. Documentation is what makes the difference, which is why we recommend photographing equipment before the season starts.
