Handyman checking the thermostatYour indoor comfort largely depends on the seamless operation of your HVAC. Since this vital appliance is often not in plain sight, most homeowners will only realize that there is a problem when it stops working.

Issues with your HVAC system’s electrical component might result in fires and other accidents. In Gastonia, being familiar with the parts of your unit can help you know when to call for AC repair. Here are some of the components affected by electrical problems.


Capacitors store electric currents that energize the unit’s compressor and fans. Any issue with your voltage leads to blowing up your capacitor. A power surge will make your circuitry overheated. In most cases, your technician will replace the faulty capacitor.


A thermostat is the most visible component of your HVAC system. The most obvious indicator of an issue with your thermostat is short cycling. This means your thermostat will turn on but switch off before your unit’s cooling cycle is complete. In other cases of short cycling, the thermostat does not switch on at all.


Your unit’s contactor closes and generates its electrical circuit. Some of the signs of a faulty contactor include failure of your system to start or shut down unless you flip the circuit breaker. Frost inside your system can also indicate that your contactor is stuck in one position.

Any sign that the breakdown of your unit is connected to the given components calls for prompt expert repair. This protects your property from an electrical fire and prevents other problems. Timely repair or replacement of the given parts also prevents high energy consumption.
