What is the Common Reason of Compressor Failure?

You might have sometimes heard the AC replacement Vancouver WA says that the bill could be expensive due to compressor failure.

If you’re wondering why your compressor failed or what the usual suspects are when it comes to ac compressor failure, then you’re in the right place.

But, have you ever wondered why compressor failure almost halts the cooling process and repairing or replacing the compressor can cost thousands of dollars? All Around Mechanical experts are to explain everything regarding the AC compressor. 

What is an AC Compressor, and Why is it Expensive?

A compressor is expensive because it is the main element or the core of the AC system. An engine sets the cooling process in motion, and you chill in the AC system’s freezing air inside your residence. Before learning what an AC compressor is, and its function, it is essential to know about the refrigeration cycle.

What is a Refrigeration Cycle?

The refrigeration cycle or cooling cycle is a process that helps to process the room-temperature air and turn it into low-temperature, freezing air that brings goosebumps on your skin. There are four essential elements in this process, and they are: 

  • Compressor 
  • Evaporator 
  • Condenser 
  • Expansion unit 

Refrigerant is the essential element that helps in the freezing process. Refrigerant is a chemical fluid that goes under expansion and compression to produce cool air. When the refrigerant is compressed, its temperature and pressure are low. The low-temperature gas evaporates and rises upwards as it passes the evaporator. The processed refrigerant meets the air and transforms it into cool air.

What are the Reasons that Cause a Compressor Failure?

According to our AC repair Vancouver WA, the compressor does not malfunction until and unless: 

  • The compressor is exhausted because it has worked overtime 
  • The compressor is old, and its functioning reduces due to working more than its life 
  • External reasons. 

We have a made list of all the external reasons that can cause the compressor failure before its lifetime period:

  • Dirty and Blocked Coils

According to our AC installation Vancouver WA, a blocked condenser coil is one of the main reasons that causes compressor failure sooner than expected.

When grime, dust, and other debris accumulate in the condenser coils, the mineral deposits build inside the AC coils. These things hinder the airway, causing improper disposal of the heat out of the system.

  • Clogged Refrigerant Pipes 

Refrigerant pipes are a network in the AC system through which the refrigerant travels to each component and transforms. When the debris gets stuck inside the refrigerant pipes, the workload increases as the AC components do not have sufficient gas to work.

  • Low Refrigerant Levels in the Tank

When the refrigerant tank gets empty, there is insufficient fluid to circulate to the components. In addition, sometimes, a leak in the refrigerant pipes causes evaporation of the refrigerant gas in the air, decreasing the levels in the tank. 


Incorrect repairing on the compressor can also increase the compressor issues. The solution to keeping the AC compressor healthy is calling the ductless AC service Vancouver on time and hiring a professional technician to deal with the AC system.
