An air conditioner’s compressor is responsible for pumping refrigerant through the unit, allowing it to produce cool air. The compressor turns the liquid refrigerant into a gas that then travels through the condenser. A problem with the compressor will cause the entire system to break down and require professional repair.
How To Spot A Bad A/C Compressor
There are a few signs of a faulty compressor that you should be on the lookout for.
1.Growling, screeching, or clattering noise
Electrical failure in the compressor could lead to unusual clunking or rattling noise. A vibrating condenser unit is another sign of a malfunctioning compressor. These signs won’t go away on their own and, if ignored, could cause even more serious damage.
2. The A/C won’t start
The first thing you should do is check the breakers to make sure they are switched on. Locate the electrical service panel, find the switch labeled A/C, and see which position it’s in. If it’s in the middle, turn it off before turning it back on.
You should also check the fuse box to make sure there aren’t any blown fuses. Start by shutting off the power supply to the air conditioner and taking the fuses out of the fuse box. Then, use a multimeter to do a continuity test. If everything seems to be working fine, then you likely have a broken compressor.
3. The A/C won’t blow cold air
Check and replace your air filters and clean the condensate lines. If you don’t have a refrigerant leak and the A/C still fails to cool your home, the problem could be the compressor.
4. Tripping circuit breakers
Running too many appliances and devices at the same time could overload the system and cause the circuit breakers to trip. This is done automatically to protect the home. However, if your circuit breakers keep tripping and you notice other problems with the air conditioner, then you need to schedule professional HVAC service.
5. Diminished airflow
If the A/C is still working but the airflow is weak, your compressor could be in the early stages of breaking down. Don’t wait until you’ve got no cool air coming at all, and call Avis Home Solutions for professional service.
