Everything you need to know about AC Compressor Failure

Blog Ac Compressors 2539462 AC compressor failure is a common problem and can be caused by some very common issues. The good news is that these issues do not require a major overhaul. Here is a closer look into the nuances of AC compressor failure.   First, it is important to understand the function of an AC compressor. It is the component that makes the air conditioner function and without it, an AC unit won’t be able to work. A typical AC compressor is expected to last 10 to 15 years and serves the function of pumping compressed refrigerant gas throughout the unit. Its main job is to ensure the compressed air is free from humidity.  

Reasons for AC compressor failure

Here is a look at the most common reasons an AC compressor winds up failing:
  • Excessive among of refrigerant
  • Dirty coils
  • Clogged suction lines
  • Electrical issues
  • Presence of contaminants
  • Wrong size suction lines
  • Refrigerant charge is low
  • Not enough oil lubricant

AC Compressor issues

If your compressor is low on Freon, it is not advisable to keep it running. When an AC unit has a low charge, it puts an added strain on the coil, which will limit its absorption capabilities. Low refrigerant can also increase the chances of overheating and cause damage to the compressor.   Compressors are also susceptible to burnout and this is often a result of motor winding temperatures that are too high. The excess temperatures break down the insulation in the motor winding and can lead to a short.   There is not always one element that can contaminate a compressor. A system can fail due because of contamination from air, acids, and dirt, which are created by the pressure and heat within a compressor. Meanwhile, electrical failures are generally a result of voltage imbalances.
