Living in South Florida means hurricane season is part of the calendar, and your air conditioner is one of the things most exposed to a storm. The outdoor condenser sits out in the open, it's tied to your electrical system, and it's the last thing you want failing in the sticky heat that follows a power outage. A little preparation before a storm — and some patience afterward — goes a long way toward keeping it intact.
Before the storm
Clear the area around the outdoor unit
Loose objects become projectiles in high wind. Move patio furniture, planters, tools, and anything else near the condenser to a secure location. The cleaner the space around the unit, the less likely something gets thrown into it.
Turn the system off at the thermostat and breaker
If a major storm is bearing down, shut the AC off at the thermostat and switch off the breaker that feeds it. The biggest threat to your system isn't usually the wind — it's the power. Storms bring surges and the rough, flickering power that comes when the grid struggles, and that can damage electrical components and the compressor. Cutting power protects it.
Consider a surge protector
A dedicated surge protector for your HVAC system helps guard against the voltage spikes that come with storms and the moment power is restored. If you don't have one, it's worth asking about before the season gets going.
Secure the unit if needed
Most condensers are bolted to a pad and don't need extra tie-downs for a typical storm, but if you're facing an unusually strong system, ask a professional about hurricane straps. Don't improvise something that traps moisture or blocks airflow — a poorly wrapped unit can do more harm than good.
A pre-season tune-up helps
Going into the season with a system that's already running well means fewer weak points if it takes a hit. A routine tune-up catches loose connections and tired components before a storm finds them for you.
After the storm
Don't rush to turn it back on
Once power is restored, resist the urge to flip everything on immediately. Power can come back unstable, and a flooded or debris-struck unit shouldn't run until it's been checked. Give the grid time to stabilize before restoring power to the system.
Inspect before restarting
Walk out and look at the condenser. Check for standing water around or inside it, debris lodged in the coil or fan, bent fins, or anything that's shifted. Look at the refrigerant lines and electrical disconnect for visible damage.
If the unit was flooded or hit, call before running it
If water rose around the unit, debris struck it, or anything looks damaged, don't power it up — running a compromised system can turn a small problem into a destroyed compressor. Have it inspected first. If everything looks clean and dry, you can restore power and start the system, watching and listening for anything unusual.
The bottom line
Most storm-related AC damage we see comes down to two things: power surges and debris. Cutting power before the storm and inspecting carefully before you restart afterward prevents the majority of it. When in doubt, a quick professional look is far cheaper than a new compressor.
Storm damage or won't restart?
If your system took a hit or won't come back on after an outage, call O'Brien. We'll inspect it before it runs so a small issue doesn't become an expensive one.
