Posted on: March 1, 2019

The day when delightful indoor comfort became an essential component of your everyday home life was a wonderful day indeed. From that moment on, you were dreading the moment when your AC would break down and you’d become deprived of its powerful cooling effect.

Why would an AC compressor stop workingBefore you go off in search of a competent provider of air conditioning repair in San Diego, it might be time to check out some of the common culprits. This is no guarantee you’ll manage to troubleshoot your AC issues all by yourself but it will give you some helpful insight.

How do I know if my AC compressor is bad?

Because replacing the compressor on your AC could be costly, impossible even, you have to first figure out whether there’s reason to suspect it to be the cause of the problem.

To find out, take the following steps:

  • Check the compressor fan air by putting your hand in front of it. The air coming from the fan should be hot because the compressor’s main purpose is to compress gas and prevent the unit from overheating. This results in heat. If, on the other hand, the air is cool or only lukewarm, the compressor could be bad or worn.
  • Check your utility bill from time to time and compare it to your bill from the same period the previous year. An inefficient compressor causes the AC to become inefficient and run longer. The result is a high electricity consumption.
  • Watch out for any strange noises. If the compressor, located in the outdoor unit, is no longer running smoothly, you could hear sounds like hissing or knocking. This could signal a problem with the compressor motor or a refrigerant leak.

Why would an AC compressor stop working?

To understand this, first you have to understand how an AC compressor works. An AC compressor, just like any other compressor or, for that matter, pump, forces the volume of a gas to decrease by increasing pressure on it. In the case of an AC, this gas (originally fluid) is called the refrigerant. Refrigerant is a substance that is used in the refrigeration cycle. Without it, the AC compressor and, by extension, the AC cannot function.

There are various possible causes of this:

  • Dirty coils
  • Presence of contaminants in the system
  • Blocked suction lines
  • Inadequate suction line size
  • Low refrigerant charge
  • Too much refrigerant
  • Inadequate oil lubricant level
  • Electrical failure
