Reasons of AC Compressor Failure

What factors contribute most frequently to AC compressor failure? It is a legitimate question that many homeowners have before AC service in Easton, MD. After all, the compressor for an air conditioner is a vital component.

Warning Signs That Your Compressor is About To Fail:

  • Little airflow: If you experience little to no airflow or warm air when it should be cool, your air conditioner’s compressor may malfunction.
  • High electricity bills: Get AC repair in Easton, MD, immediately to see whether it’s acting up and needs a remedy if you notice a sudden spike in your costs without increased usage.
  • Tripped circuit breaker: The compressor needs extra power to work because it is overheating if your outside unit frequently trips the circuit breaker.
  • Strong banging sounds: You should be alerted if your HVAC system begins to make a loud pounding noise and you observe accompanying vibrations. 

Reasons For AC Compressor Failure

  • Electrical Fault

Contactors, cables, and fuses that have been damaged can result in an electrical failure. Acids accumulate in your system due to electrical issues, which causes other AC components to break down.

  • Refrigerant Low

Low refrigerant levels indicate that there is probably a leak that has to be fixed immediately. Reduced pressure brought on by low refrigerant levels makes the compressor work harder to push the refrigerant through the system.

  • An Excess of Refrigerant

An individual with less training could not know how to fill it appropriately and end up filling it with more than is necessary. Increased pressure in the system brought on by high refrigerant levels can hasten the failure of the AC compressor.

  • Condenser Coil Obstruction

Your condenser coils might become mainly blocked due to neglect. Your compressor may overheat and quit working entirely if you keep running your system in this manner. Call a professional for AC Installation Easton MD.

  • Compressor Overheating

Your outdoor unit’s compressor can overheat if there isn’t enough airflow around it and it receives direct sunshine. Furthermore, dirty coils, low refrigerant levels, and a lack of insulation can all cause the compressor to overheat and eventually fail.

  • Evaporator Motor Displacement

The refrigerant may be forced to return to the compressor if the evaporator motor in your air conditioner is dislodged. Over time, it causes the compressor to become less effective until it eventually stops working.

  • Broken or Obstructed Suction Lines

Your refrigerator’s suction lines may eventually get holes and cracks, which will obstruct refrigerant flow throughout the system—compressor strain results from having to utilize more energy to push adequate refrigerant through the device.

  • Incorrect suction Line Sizing

Failure of the compressor can result from the suction line being either too long or too short. Incorrect size might increase pressure and cause the compressor to overheat. For any AC repairs, it is usually preferable to consult a professional.

  • Not Enough Lubrication

For optimum performance, your HVAC system needs the proper amount of lubrication. If there is insufficient lubrication, wear and tear will rise, and your compressor will have to work harder. Leakage from the evaporator, condenser, pipe connections, or compressor shaft seal is the leading cause of lubricant loss.

  • Debris and Dirt in the Outdoor Unit

Dust, debris, soot, and moisture from the outside can enter your outdoor unit and harm your compressor.
