3 Telltale Signs That Your Air-Conditioning Air Compressor Is On The Verge Of Failing Or Has Failed

Most people do not know the specifics of their HVAC systems or how to repair them. However, many know that the air compressor, which is a part of the AC system is a critical part of the system. Some might even consider it as the "heart" of the AC system. If an air compressor fails, it can be an expensive repair because this crucial part can cost a significant amount of money. Some HVAC contractors might recommend upgrading to a new air-conditioning system when the compressor in a system fails. If you are wondering how to tell if an air compressor is failing, continue reading.

Breaker Tripping

First, it is important to understand the purpose of a circuit breaker. When a circuit breaker trips, it is a safety feature to protect homeowners against electrical fires and property loss. You do not need to be concerned about the breaker for your AC system tripping every once and a while. However, if it repeatedly trips, do not continue to reset it. This is a sign of a circuit breaker that is tripping due to an air compressor overheating. Forcing it to operate can result in compressor failure.

AC Blowing Warm Air

The air compressor's key role is to pump refrigerant. If there is not enough refrigerant in the system, the compressor will try to circulate the little amount that is present. The issue is that the refrigerant may continue to deplete if there is a refrigerant leak present. An AC system that blows warm air might also be a sign of an air compressor that has already failed. An HVAC technician will need to inspect and diagnose the problem.

Unusual Condenser Noises

One of the telltale signs of a failing air compressor is the onset of noises coming from the condenser unit. AC systems that are in need of repair can make a variety of noises. Some of these noises are not related to the air compressor. However, when other critical parts such as fans and belts in condenser units break or get dislodged, they can put a strain on the compressor. This could lead to premature failure of air compressors. 

Routine residential AC service is the best way to extend the life of your air-conditioning system. It gives technicians the opportunity to inspect  AC systems and identify failing components. Sometimes an air compressor that is on the verge of failing can be repaired to extend its lifespan. However, compressors that fail need to be replaced or a system upgrade will be needed.
