How to Reset Your Air Conditioner After a Power Surge

Thunderstorms are a common occurrence in the Florida area. It is the lightning capital of the U.S., after all, receiving up to 1.4 million lightning strikes per year. Some thunderstorms can even be strong enough to cause damage to your property, flooding and power outages. If a flash of lightning strikes a power line in your area, it could cause a power surge, an outage or both.

When this happens, your appliances that run on electricity will shut down and could even suffer damage. If your AC is affected, in most cases a timely AC repair can get it up and running again. At times, though, the unit may be damaged beyond repair and will require a replacement.

In some cases, it’s not the power outage itself that damages your AC unit; rather,  it’s the damage that occurs when the power turns back on. To protect your AC from this kind of damage, learn how to reset it in the event a power outage occurs. Note that you should follow these steps even if the power only surged and came back on immediately. Don’t allow your AC to keep running when these things happen. Here’s what you should do:

Turn off the AC at the thermostat. On your thermostat, look for the system switch and set it to Off. This is the easiest way to turn off your AC and protect it from a strong power surge when the electricity comes back on.

Set the circuit breaker to Off. It’s not enough to set the thermostat to Off. To further protect your HVAC unit from a power surge, locate the circuit breaker to which it’s connected and set that switch to Off as well.

Set the circuit breaker to On. After about a minute, set your circuit breaker back to On. Cutting the power and turning it back on at the circuit breaker level is also a normal part of AC installation.

Don’t turn on your AC just yet. When you’ve turned the power on again at the circuit breaker, don’t rush to turn on the AC or you risk causing damage. Its internal circuitry needs a little time to reset, so wait for about 30 minutes after turning on the breaker. To turn the AC back on.

Turn on the AC at the thermostat. Half an hour after turning on the breaker, you can turn on the AC at the thermostat. Observe if it’s running normally. If it is, then everything’s fine. If it doesn’t turn back on or if something feels out of the ordinary, turn it off at the thermostat and then at the circuit breaker, then call a professional technician to take a look.
