The objective of an AC compressor is to compress the ac refrigerant gas that arrives from the house from little to high force and send it to the aircon condenser, which changes it from a gas into a liquid form. The condenser and compressor are placed outside the house and when problems with the compressor start to arise it cause a high power bill, shutting down of the AC unit or lukewarm air instead of chill air. There are many ways to check if your problems are due to a bad compressor or noisy aircon compressor.
Testing aircon compressor
You can test your aircon compressor with these simple 5 steps
Total time 30 minutes
Use your hand to test the compressor.
If the air coming from the fan is chill or lukewarm, then the compressor is worn or bad. When the compressor compresses the gas to high force, heat is created and expelled by the fan to ensure the unit does not warm. If the air is chill or lukewarm, then the compressor is not working right to compress the gas.
Keep an eye on your power bill.
If your power bill starts to climb and you have not had an increase in AC usage, the compressor is likely worn or bad. If the compressor is not compressing the gas enough, then it reduces the efficiency of the unit as a whole. It causes the AC to run longer and then will increase the power bill.
Listen to the unit when it start.
When you pay attention to the exterior unit, you will hear the perfect working of the compressor fan and compressor. If there are issues, you may pay attention to a hissing produced by gas leak refrigerant, a knocking noise if the compressor machine is not working rightly, and a big period of time for the unit to start up.
Loud noises when the air condition is switched on is another potential sign of a failing AC compressor.
The air conditioner compressor has many interior parts and uses a preserved bearing to turn. If any of the interior parts break, or the compressor internal bearing seizes or fail, then all types of noises can be produced as an outcome. A leaking or exhausted bearing will generate a high grinding sound or pitched squealing, while a seizing or held bearing will generate a grinding sound or a clear belt squeal. Due to the nature and complexity of how compressors are assembled, it is generally simplest to change the full compressor instead of attempting a repair.
Check the clutch
Another sign of a problematic compressor is the clutch for the ac compressor is not moving. The clutch on the compressor is what permits the pulley to disengage and engage from engine power so that the compressor is just turning when it needs to be. The clutch can grab, when continue keeps the compressor make active, or it can crack, which means the compressor will be capable to get engine power. Sometimes the clutch itself can be changed, but generally changing the full compressor turns out to be the most competent repair.
