The AC compressor bearing is one of the most critical components in the air conditioning system. Its main functions are: first, to support and guide compressor rotors, making them perform without displacement, second, to reduce friction and load, preventing the unit from excessive wear and thereby prolonging the lifespan of the component.
Typically, there are three major signs to show that your AC compressor bearing is bad.
Unusual Noiseย
If you hear grinding or squeaking sounds from the AC compressor, then there is something wrong with your AC compressor bearing. This can happen due to an inappropriate installation of the bearing. Compressor rotors will misalign if the bearings are mounted wrong. Thatโs why unusual noise occurs.
Abnormal Vibration
The AC compressor bearing ensures that the compressor performs smoothly by reducing friction between components. Continuous vibration and abnormal noise may indicate insufficient lubrication. If this is the culprit, just refill what the system needs. If not, replace the AC compressor bearing immediately to avoid extensive damage to adjacent parts.
System Leakage Occurs
ย Although the damaged bearing itself canโt lead to refrigerant leakage in the air conditioning system, it can result in a displacement and temperature rise of the major rotor, which can speed the misfunction of the oil seal, finally causing refrigerant and oil leakage. If your AC unit shows a shortage of refrigerant and oil, along with unusual noise and vibration, there is possibly damage to the AC compressor bearing and oil seal.
