Protecting Your AC During Hurricane Season

Miami's hurricane season runs June through November — right through peak cooling months. A little preparation protects your AC from storm damage and gets you cool again faster afterward.

Before the storm

• Turn the system off at the thermostat and breaker as the storm approaches. Power surges and flickers during a storm are a leading cause of compressor and control-board damage.
• Don't cover a running unit, but if you have a proper condenser cover, use it once the system is off.
• Clear the area around the outdoor unit — loose furniture and debris become projectiles.
• Consider a surge protector — a whole-home or dedicated HVAC surge protector is cheap insurance against the exact surges storms cause.
• Never strap or "hurricane-proof" the unit yourself in a way that blocks airflow; ask a pro about proper tie-down brackets if flooding or wind is a concern.

During the storm

Keep the system off. Cooling during active lightning and surging power risks expensive damage for little benefit.

After the storm

• Wait for stable power before restarting — generators and unstable grid power can harm the compressor.
• Inspect the outdoor unit for debris, flooding, or shifted position. If it was submerged or struck, don't run it — call for an inspection.
• Check the electrical disconnect and breaker.
• Turn the fan on first for a few minutes, then cooling, and listen for anything unusual.

If your AC was flooded or damaged

A flooded condenser or a unit hit by debris needs professional inspection before it runs again — electrical and refrigerant components can be compromised in ways that aren't visible. Our emergency team prioritizes post-storm calls across Miami-Dade.

Year-round protection

A surge protector plus twice-yearly maintenance is the best defense — a tuned system with protected electronics rides out storm season far better.

Frequently asked questions

Should I turn off my AC during a hurricane?

Yes. Turn it off at the thermostat and breaker as the storm approaches to protect the compressor and control board from power surges and flickers.

Can I run my AC after a power outage?

Wait until grid power is stable — running on unstable power or a generator can damage the compressor. Turn the fan on first, then cooling, and listen for anything unusual.
