After a Daphne Summer Storm: When to Restart Your AC (and When to Wait)

What actually breaks during a Daphne storm

It's almost never the wind. Outdoor AC units are designed to handle 100+ mph gusts and rain — they're not the vulnerable component during a tropical storm or hurricane brushing Mobile Bay. The real damage source is grid power-cycling: as transformers blow, substations switch over, and Alabama Power restores feeders, the grid flickers on and off through the storm and the recovery period. Each restart slugs the compressor with refrigerant it can't immediately handle, and burns capacitors a little more each time. By the third or fourth flicker, you've shortened the equipment's life by years.

Lightning damage runs a close second. A direct strike near the home — even a few hundred yards away — can fry control boards, capacitors, contactors, and thermostat low-voltage circuits. Lightning damage typically shows up the next morning as "the AC was running fine before the storm and won't start now." Sometimes it's the outdoor unit, sometimes the indoor air handler control board, sometimes the thermostat itself. Diagnosis requires testing each component, not guessing.

The safe-restart procedure

Wait for stable grid power. Don't restart the AC during the first 6-12 hours after grid recovery — Alabama Power is still re-establishing capacity and feeders will continue to flicker. Each flicker damages the compressor a little more.

Inspect the outdoor unit visually. Walk around the condenser. Look for debris in the coil fins, fan blade damage, water in the electrical compartment, displaced concrete pad, downed branches against the cabinet. If anything looks wrong, leave the breaker off and call us.

Restore power one breaker at a time — outdoor disconnect first, indoor air handler breaker second. Listen for unusual sounds. Set the thermostat 8-10°F above current room temperature; let the system come up to load gradually over 2-4 hours rather than asking it to cool the home aggressively right out of the gate.

Symptoms that mean call us

If after restoring power you see: AC was running fine before the storm and won't start now (lightning damage to control board or capacitor), outdoor compressor hums loudly but the fan doesn't spin (failed run capacitor — common post-storm), system short-cycles on and off rapidly (failed contactor or thermostat low-voltage issue), cool air for 5-10 minutes then warm air (refrigerant charge issue from a damaged line set), or loud grinding from the outdoor unit (debris in fan blade or fan motor bearing damage) — kill the breaker and call 251-383-HVAC. Don't keep cycling a damaged system.

Cool Comfort Plan members and storm-response-tagged customers get prioritized routing in the 48-72 hours after any named-storm event. We keep extra inventory of the most common post-storm failure parts (capacitors, contactors, control boards, thermostats) so we aren't waiting on supply chain when call volume spikes across Daphne, Olde Towne, Lake Forest, and the Highway 181 corridor.
