How to Protect Your HVAC System from Hurricanes
July 21, 2025

When hurricane season starts in Southwest Florida, protecting your home becomes a priority. Outdoor AC units are particularly vulnerable to hurricane damage. Hurricane season lasts a full six months from June 1 to November 30 each year, making it essential to prepare and protect your AC from a hurricane before storms hit.
There are plenty of things you can do to prepare your AC unit for hurricane season, including:
- Inspect and secure your outdoor AC unit
- Turn off the system before the storm hits
- Cover and protect vulnerable components
- Check and restore your system safely after the storm
Read on to learn more about preparing your AC system for a hurricane.

Inspect and Secure Your Outdoor AC Unit
AC unit preparation for hurricane season in Florida starts with a thorough inspection:
- Check your entire unit, looking for signs of wear or corrosion, especially on brackets or at the base of the AC.
- Tighten any loose screws, bolts, or panels to reduce the risk of something coming loose in high winds.
- Handle any AC maintenance tasks, such as changing filters and checking electrical connections.
Hurricane straps for AC units secure the system to its concrete pad, helping to prevent shifting or toppling. Consider installing a cage to keep out flying debris. You can also trim nearby shrubs and trees to reduce the risk of branches and leaves damaging your AC.
Older units or loosely installed units may need to be reinforced before hurricane season. A concrete pad provides wind resistance and keeps your AC unit in place.
Turn Off the System Before the Storm Hits
During a hurricane, power surges can damage your HVAC system and put your home at risk. Lightning strikes or blown transformers can send electricity down the line, damaging electrical components and the AC compressor.
Shutting off the system at the main breaker reduces the chances of a catastrophic event and prevents the unit from turning on during a storm. To keep temperatures comfortable during the storm, pre-cool your home by lowering the thermostat for a few hours before you shut off the unit.
Cover and Protect Vulnerable Components
Water and debris could damage vulnerable components inside your AC. A breathable, manufacturer-approved AC cover provides better protection than a plastic tarp, which can trap moisture inside the unit.
A plywood or metal cage offers additional protection. Remember to remove the cover once the hurricane has passed so your unit gets sufficient airflow once you turn it back on.
Check and Restore Your System Safely After the Storm
After a hurricane, you should inspect your HVAC system before restoring power. Check for tripped breakers, disconnected wires, visible damage, and debris or flooding that might affect performance or cause it not to work.
Avoid restarting your AC if you notice water pooled around the base, and call a licensed HVAC technician for a professional inspection and AC repair service if you have any concerns about possible damage.

Why Should You Cover Your AC Unit Before a Hurricane?
Covering your outdoor AC unit before a hurricane keeps out moisture and flying debris, such as branches and garden decor caught by storm winds.
When Should You Prepare Your AC for a Hurricane?
Inspections and maintenance should be done before hurricane season starts on June 1 or in the early part of the season. Immediate preparations, including turning off your unit and securing it with straps, can be handled within the 24 to 48 hours before a storm is expected to hit your area.
