5 Causes Of Air Conditioner Compressor Failure


The compressor works by compressing the refrigerant and pumping it throughout the system to collect heat and humidity. Your system can never function without it.

As a homeowner who relies on air conditioning systems for your summer comfort, you should know that the compressor plays an important role in the overall performance of your unit. Once it fails, expect that you are in a big, very expensive trouble.

So, what are the things that can harm your compressor? Read and find out!

  • Dirty Coils

Dirt accumulation can happen in the condenser coils after months of continuous work. Without proper maintenance, the build-up of these particles becomes insulators, which hinder the coils from expelling heat from the system. This increases pressure and will soon cause the compressor to overheat and fail.

  • Low Refrigerant Level

The only causes of refrigerant insufficiency are holes and cracks in the refrigerant line. If neglected, your unit will run out of refrigerant and cause havoc in its performance, especially the compressor. Low refrigerant level adds pressure to the compressor, making it work harder to pump the substance to the system. Too much strain can cause the component to break down.

  • Too Much Refrigerant

Too much of anything is dangerous. The same thing applies if too much or the wrong type of refrigerant is added to your air conditioning system. Incompatibility can cause your compressor to stop working altogether.

  • Blocked Refrigerant Lines

The refrigerant flows in the refrigerant lines. If blocked, it can lead to pressure build-up and cause the temperature to rise. As a result, overheating happens, and eventually, the compressor breaks down.

  • Electrical Problems

Electrical problems usually start as a small glitch and build up rapidly when neglected. Yet, once your compressor is damaged by an electrical issue, compressors are hard to repair and replacement may be the only option left. This is an issue which can be prevented by regular maintenance service, so better check on your schedule annually.

Signs of a Failing Compressor

You know you have a malfunctioning compressor if:

  • You notice odd sounds like chattering, rumbling, or ticking noises in the system
  • Diminished airflow and warmer air
  • The system keeps tripping the breaker
  • The outside unit shakes when it starts up
  • The compressor doesn’t turn on
