Your Noisy A/C Compressor: It’s Squealing for Attention

TeamBobs 9.17.13If you are experiencing a noisy A/C compressor, it would likely be wise to have the sound checked out by a professional immediately. Although some unusual noises that emerge from your compressor simply indicate the need for a minor adjustment, others may signify a more serious issue. By putting off the maintenance or repair of a smaller problem, your air conditioning unit may be significantly damaged. Your professional HVAC technician is trained to recognize the source and significance of unusual compressor noises in order to evaluate such things as operation condition, and even the remaining life of your unit.

  • Banging or clanking noises can indicate issues within the sealed unit of your air conditioner, and the sealed unit can not be repaired; it must be replaced. This can be very costly. Similar noises, however, can signify the need for a minor adjustment or loose parts elsewhere in your unit. A professional technician is trained to know the difference.
  • Squealing sounds are often heard when an air conditioner first starts up. Squealing noises that continue after start-up, or any new noises should be reported to your HVAC professional promptly.
  • Humming sounds that are coming from one of the motors can indicate that a capacitor needs replacing. Another cause for this noise is often an indication that the compressor motor has seized. If you experience humming, turn off your unit and contact a technician.
  • Hissing noises can indicate excessive pressure build up in your unit, and can be very dangerous. A high pressure sensor should automatically shut you unit down when this occurs, but in the event that it doesn’t, shut the unit down manually and call a professional.

Although many causes of a noisy A/C compressor call for only minor repairs, needed maintenance, or adjustments, it is dangerous to attempt to diagnose your problem without the assistance of a trained professional.
