5 common Reasons Behind AC Compressor Not Working

blog post bg

The compressor of your air conditioner may stop working for various reasons. Frequently, the failure of an air conditioning compressor can be traced back to preventable faults requiring AC repair in Babylon.

What is a Compressor, and How Does It Work?

A compressor for an air conditioner has two functions: first, it brings the molecules of the refrigerant closer together by compressing them, and second, it pumps the refrigerant throughout the system. This gas is compressed and heated further by the compressor, transforming into a hot liquid. The liquid is subsequently cooled by the condenser coil, which is positioned outside.

The expansion valve lowers the pressure when the refrigerant returns to the evaporator to begin the cycle again. It allows the refrigerant to absorb heat and convert it into a gas more efficiently. Any leaks or damage to the compressor could render this technique ineffective. 

Five Most Common Causes of a Non-Functioning Air Conditioner Compressor:

  • Charge Reduction of the Refrigerant

There may be instances where refrigerant lines in your system crack or develop holes. As the refrigerant running through these lines begins to leak, the refrigerant charge in your system will decrease.

  • Overheating Compressor

If you fail to acknowledge this problem promptly, the system will overheat, and your compressor will finally quit functioning. This issue will cause the system to overheat if it is not addressed promptly. If the compressor fails, you must spend substantial money on AC repair in Babylon.

  • The Size of the Suction Line is Incorrect

Consider that your refrigerant line has developed a leak and needs to be replaced. Therefore, one should ensure that a trained HVAC technician in Babylon performs the replacement. A line that is either too large or too small for your system can cause the compressor of your air conditioner to fail prematurely.

  • Inadequate Oil Lubricant

The correct amount of oil and lubricant is necessary for your air conditioning unit to perform correctly. Inadequate oil lubricant will prevent your air conditioning system from operating properly and may eventually cause the compressor to malfunction. In light of this, you should utilize the services of a professional, such as an AC contractor in Babylon.

  • Electrical Malfunctions

There is no forever reliable electrical system, and the same holds for an air conditioner’s circuit board and wiring. Over time, the accumulation of acids and oxidation will eat away at the circuit connections, leading to their breakdown and loss of power.

Ultimately, this will prevent power from reaching the air conditioner’s compressor, resulting in the compressor turning off abruptly and without warning. Unless you have professional training as an HVAC technician in Babylon, you will have difficulty identifying and correcting an electrical problem.


It may be necessary to replace the compressor in your air conditioner, which can be an expensive repair. Keeping this in mind, you will need to perform routine maintenance on your air conditioning unit to prevent this from occurring.
