Your air conditioner’s compressor is often called the “heart” of the system and for good reason. It is responsible for circulating refrigerant and enabling the heat transfer process that cools your home. When the compressor starts to fail, your entire air conditioner system can struggle or stop working altogether. LV Heating & Cooling will highlight some of the early warning signs of a failing compressor and help you avoid a complete breakdown and costly emergency repairs.
What Does the Compressor Do
The compressor is located in your outdoor air conditioner unit. Its job is to pressurize the refrigerant and move it between the evaporator and condenser coils. Without it, your air conditioner cannot effectively remove heat from your home.
Warm Air Coming from Vents
One of the first signs of compressor trouble is when your air conditioner is running but blowing warm air. When there is a failing compressor, it can’t properly circulate refrigerant, which prevents your system from cooling the air.
Loud or Unusual Noises
Your outdoor unit should run relatively quietly. Strange noises often signal internal issues. Some of the more common and concerning noises to listen for are:
• Grinding
• Clanking
• Rattling
• Screeching
These noises may indicate worn or damaged compressor components.
Hard Starting or Trouble Turning On
If your air conditioner struggles to start or takes longer than usual to kick on, the compressor may be failing. This could be caused by electrical issues, failing start capacitor or internal wear and tear of the compressor components.
Frequent Circuit Breaker Trips
A failing compressor can draw too much power, causing your circuit breaker to trip repeatedly. If this happens often, turn off your system and call a professional as this can be a serious electrical concern.
Reduced Cooling Performance
Even if your air conditioner is still producing cool air, a weak compressor may not perform as efficiently as it should. You may notice longer cooling cycles, difficulty reaching the desired temperature or uneven cooling throughout the home.
Short Cycling
A malfunctioning compressor can cause your system to turn on and off frequently without completing a full cooling cycle. Short cycling can increase energy bills, place more wear and tear on components and reduce system lifespan.
Refrigerant Leaks Around the Unit
While not always caused by the compressor itself, refrigerant leaks can lead to compressor damage over time. If you have a refrigerant leak, listen or look for hissing sounds, ice on refrigerant lines or poor cooling performance.
Outdoor Unit Not Running
If the indoor unit is running but the outdoor unit is not, the compressor may have failed. Compressor failure could be due to an electrical failure, burned-out compressor or faulty wiring.
