How should I prep my AC for hurricane season in Southwest Florida?

Surge Protection Before a Storm Ever Reaches the Coast

Lightning strikes and grid fluctuations are common during a named storm, and the outdoor condenser is one of the more exposed pieces of equipment at your house. Power does not always fail cleanly either. As utilities work to restore a neighborhood, it can flicker on and off several times before it settles, and each flicker is a small surge event for anything still wired in. A whole-system surge protector installed at the outdoor unit or the electrical panel is the standard safeguard against this, and it is worth confirming yours has one before storm season gets underway rather than after a strike takes out a control board.

This is a reasonable thing to ask about at a routine AC maintenance visit, since a technician is already at the unit and can tell you what is and is not in place.

Clearing the Outdoor Unit So the Wind Has Less to Throw

The condenser's fins are thin aluminum, built to move air efficiently, not to survive a direct hit from a flying branch or an unsecured planter. Before storm season, trim back any branches or palm fronds hanging near the unit, and walk the yard for anything loose that wind could pick up: patio furniture, potted plants, trash cans, garden decor. Secure it, store it, or move it well away from the unit's location. A gentle rinse of the outdoor unit's coil and fins beforehand also clears out mulch, grass clippings, and debris that has built up over the season, so the unit is starting from a clean baseline going into the storm rather than already struggling with restricted airflow.

Most outdoor units are already secured to a pad or mounting brackets, but it is worth a quick visual check that nothing has shifted or loosened since the unit went in, especially on an older system. If the pad looks cracked or the unit looks like it is sitting unevenly, that is worth pointing out before storm season rather than during it.

Setting the Thermostat Before You Evacuate or Lose Power

If you are leaving ahead of a storm, or an extended power outage looks likely, there is little reason to leave the system actively cooling a house that is about to be shut up and unattended. Many homeowners simply turn the thermostat off before they go, since the power may well be cut by the storm anyway. If the system has already been showing signs of freezing or struggling before the storm hits, switch the thermostat to off, not just up, to protect it rather than leaving it to run against a problem while no one is home to notice.

Restarting Safely Once the Power Comes Back

Give the power a little time to stabilize before you turn the system back on, especially if it flickered a few times as it was restored. When you do switch it back on, treat it like any other appliance coming back after an outage: if it starts normally and runs, you are in good shape. If it trips a breaker, will not start at all, or you notice a burning smell, shut the system off and call right away rather than trying it again.

If the outdoor unit took a visible hit during the storm, bent housing, standing water around or inside it, debris lodged in the fins, leave it off and have it looked at before powering it up. A unit that looks fine from a few feet away can still have damage that is not obvious until it is running.

Do Not Forget the Indoor Equipment

The outdoor condenser gets most of the attention, but the air handler indoors, often sitting in a garage, closet, or attic, deserves a look too. Before storm season, make sure nothing important is stored directly beneath an attic air handler or its drain pan in case of a leak, and clear the space around a garage air handler so wind-driven rain has less of a direct path to it if a garage door takes a hit. A few minutes of clearing space now is a lot easier than dealing with water damage on top of storm cleanup later.
