Air conditioners are complicated electrical devices. The combination of an intricate electrical system and the use of chemical refrigerant makes it tricky for a non-professional to be able to diagnose what’s wrong with an air conditioner, let alone understand how to fix it.
Electrical issues are the most common type of malfunction that can bring an air conditioning system to a halt and cut off cooling to a house. Below we’ve listed the electrical malfunctions our technicians often see when they come to repair a customer’s faulty air conditioner.
Whenever an air conditioning system abruptly shuts down—the fan won’t come on, the compressor won’t come on—one of the first things we recommend homeowners check is their electrical panel. A tripped circuit breaker might have caused the air conditioning system to lose power. Resetting the breaker may solve the problem.
