To ensure your home environment remains comfortable, the AC must cycle properly. Unfortunately, some residents in Savannah, GA discover their AC runs almost constantly to regulate indoor temperatures, and this causes energy waste and excess wear on the system. Here are three common reasons an AC won’t shut off.
1. A Bad Thermostat
The average life of a thermostat is 10 years, but they require service at times within that period. Loose and damaged wires as well as dirty sensors prevent the thermostat from working properly and sending the right message to the HVAC equipment. This issue requires attention from an HVAC technician, and you must replace old or severely damaged thermostats.
2. A Dirty Condenser and Coils
The condenser and condenser coils play a crucial role in extracting heat energy from the air, but they must remain clean to function properly. If the equipment becomes dirty, it restricts airflow through the condenser and reduces the cooling efficiency of the condenser coils. To maintain the desired cooling level in the home, the air conditioner often runs almost continuously until a professional cleans the parts during an HVAC maintenance service appointment.
3. Frozen Evaporator Coils
Frozen evaporator coils prevent the condenser from properly cooling the air. As a result, the AC system blows warm air, and the home never reaches the desired temperature. Addressing the cause of the frozen evaporator coils is an essential step to restoring the proper functionality of the air conditioning system.
An air conditioner that fails to shut off indicates a potentially serious issue, so it requires a professional diagnostic service and proper repairs as soon as possible. For dependable AC repair service in Savannah, GA, contact McDevitt Air today.
