Identifying Air Conditioning ProblemsIdentifying Air Conditioning Problems

An air conditioning compressor is responsible for elevating the pressure and temperature of the refrigerant to transform it into a high-pressured gas that can be used to help facilitate the unit's cooling process. As a vital part of the early stages of the cooling cycle, when a compressor doesn't function correctly — the air conditioning unit will also not operate correctly. 

Hot Air

If your air conditioning is blowing out warm air, it's never a good thing. Refrigerant is one of the most important elements in the cooling process, as it works to support the coils that cool the air. Any problem with the refrigerant will lower the cooling power of the unit. 

Naturally, if the compressor is not adequately pressurizing and elevating the temperature of the refrigerant, it won't function like it needs to. Keep in mind that a unit that blows hot air could be the result of several other issues, so you need to have the unit inspected to be certain of the problem. 

Unusual Sounds

The air compressor works by way of a powerful motor, so any issue with the motor will lead to problems. An air compressor motor generally operates without causing any noise that is audible outside the unit, but when the motor is worn, some of the components on the inside start to fall apart or loosen. The result of this action is a rattling noise that is especially audible when the cooling unit first powers on.

Depending on the extent of the damage, a technician might be able to replace the faulty part within the motor, otherwise, a complete repair or replacement of the motor might be necessary to resolve the issue.  

Power Loss

When an air conditioning unit keeps losing power, a problem with the air compressor could be to blame. As a compressor starts to fail, it generally starts to work harder to produce results. The outcome of this increase in power exertion also means an increase in the amount of electricity the air conditioning system uses, which can ultimately cause it to overload the power system.

When the system is overloaded, it can trip the circuit breaker and terminate power to the unit. Until the compressor is repaired, the breaker will continue to trip. As a result, the unit could power off for long periods when you are away from home, even when it's hot outside.

Do you recognize any of these red flags? Speak with an air conditioning repair professional to have your compressor inspected.
