Has Lightning Hit Your Ac System? Here Is How You Can Get It Back To Work


What are the three most important aspects of a Florida summer? Sweltering heat, thunderstorm, and incidences of AC breakdown. During this 12 to 16 weeks stretch of summer, South Florida experiences one of the nation’s highest number of lightning strikes. After a hurricane passes over a place, it’s natural for the area’s AC repairing shops to receive dozens of phone calls from concerned homeowners saying that their units have stopped working. There can be a variety of problems. In most of the cases, machines do not start at all while in some others, the AC keeps running but fails to perform according to expectation. In such situations, the AC fails to cool the room and keeps on circulating the warm air.

First, Check the Thermostat

Turn the thermostat on to see if the light on it blinks. The light indicates that the thermostat is getting power. If you don’t see the light, check your breaker. If there is any electrical issue, address it and if you cannot find any issue but the thermostat still won’t work, call your repairing agency. If you are using a battery-powered thermostat, first replace the battery and see if it works, before calling a technician.

Take a Look at the Fan Unit

An AC unit comprises an indoor fan and an outdoor condenser. If everything is okay, the fan and condenser part is expected to start almost simultaneously. If that is not the case, first, check the circuit breaker. In the event of any electrical damage, the breaker will again trip as soon as you switch on the unit. In such a situation, you will need help from a professional.

If the circuit breaker does not trip and yet the AC does not start, the fault might be with the outdoor condenser unit.

Check the Outdoor Condenser

Outdoor condenser units generally have two circuit breakers within a few feet gap. You will have to test the switch inside. Look for a large gray colored electric whip on the panel; it will tell you where to look for the breaker. Reset the breakers and then turn on the AC. If one of them trips immediately, contact your technician.

Note the Details

If you suspect a lightning damage, document all the details of the event including its date and time. An accurate documentation of the event will help you with your insurance claims. If the lightning damage is severe, you may need to replace it with an all-new unit. These details will then help strengthen your application.

If you suspect that the repeated issues you’ve been experiencing with your AC have to do with the latest thunderstorm in your area, examine the unit thoroughly.
