Signs That Your Compressor Needs Repair

A compressor is a vital component of any air conditioning or refrigeration system. It pressurizes and circulates the refrigerant, which transfers heat from one place to another. Without a properly functioning compressor, your system will not be able to cool or heat your home or business effectively.

However, compressors are also subject to wear and tear over time, and they can develop various issues that affect their performance and efficiency. If you ignore these issues, you may end up with a broken compressor that requires a costly replacement.

To help you avoid these problems, here are some signs that indicate your compressor needs repair.

Strange Sounds or Vibrations

One obvious sign that your compressor needs repair is if it starts making unusual sounds or vibrations. This could indicate a range of issues, such as worn bearings, loose parts, or even a failing motor. Some of the common sounds that indicate a compressor problem are:

  • Clanking. A clanking noise usually means that you have a part that is loose or broken, often a connecting rod, crankshaft, or piston pin.
  • Hissing or bubbling. A hissing or bubbling noise could mean that you have a refrigerant leak in your system. This can cause your compressor to overwork, overheat, or damage the environment and pose health risks.
  • Clicking or rattling. A clicking or rattling noise could mean that you have an electrical issue with your compressor, such as a faulty relay or capacitor. This can prevent your compressor from starting or running properly.

If you notice any unusual noises or vibrations coming from your compressor, you should schedule a repair.

Decreased Performance

If you notice a drop in the performance of your compressor, such as reduced airflow or pressure, it could also be a sign that it's in need of repair.  Poor performance may be caused by a variety of issues, such as valve damage, piston wear, or clogs in an air filter. Some of the common symptoms of decreased performance are:

  • Warm air. If your system blows warm air instead of cool air, it could mean that your compressor is not compressing the refrigerant enough to remove heat from the air.
  • Short cycling. If your compressor turns on and off frequently, it could mean that it's struggling to maintain the desired temperature or pressure. This can cause your system to consume more energy and wear out faster.
  • High energy bills. If your energy bills are higher than usual, it could mean that your compressor is running inefficiently and wasting energy.

Regardless of the cause, decreased performance can lead to inefficiencies in your operations and should be addressed as soon as possible. If you have noticed signs that your compressor needs repair, contact an HVAC specialist like American Mechanical Systems in your local area.
