Listening to a Broken AC Unit
Everyone’s air conditioning unit makes some type of noise when it’s functioning, but the type and quality of the sound can be a diagnostic tool. If you notice new sounds, or if the unit is louder than normal, it could indicate that you need AC repair.
AC is Making Screaming, Screeching, or Whistling Sounds
In addition to being annoying at best and unnerving at worst, a screaming or screeching sound could indicate a major issue with your AC. Turn off your air conditioning unit immediately, as these sounds could be caused by a refrigerant leak. If it is leaking, the fluorinated hydrocarbons found in traditional refrigerants can be toxic if inhaled in high amounts. Keep the AC off, avoid the unit itself, and get in touch with one of our licensed techs for emergency AC repair.
If it sounds higher pitched rather than whistling, it could instead be a pressure imbalance in your compressor. While this imbalance isn’t as dangerous as a refrigerant leak, it can cause premature failure in your AC’s compressor or your overall HVAC system. You’ll still need air conditioning repair, since this failure could decrease your unit’s overall cooling efficiency or result in a total shut down — and no one wants that!
AC is Making Squeaking or Squealing Sounds
These sounds are more high-pitched and could be entirely normal when your AC is first firing up, especially in the spring. When your air conditioner has been resting all winter, its components have also been weathering the elements. Your outdoor motor fans could be worn down, your blower wheel may not function properly, or the belt may have slipped off entirely, in older units.
We recommend scheduling an AC tune-up around the start of spring so our techs can ensure your unit is in tip-top shape before you need it, both to prevent repairs and to keep your cool air blowing all summer long.
