Squealing Sounds

Squeals, squeaks, and rattles, many times, indicate a problem with your AC unit’s fan. Blower motors emit loud squealing sounds when they are about to fail, creating a pretty annoying sound that usually gets the attention of homeowners right away. Parts such as the blower wheel and AC housing will also emit this sound when they are malfunctioning–thankfully, they are fairly easy to repair or replace and won’t affect the longevity of your AC unit if taken care of immediately. Our HVAC specialists at Academy Air in St. Louis, MO offer AC repair, installation, and maintenance services for residential and commercial properties experiencing squealing sounds.

Clanking Sounds

The outdoor fan, indoor blower, or the unit’s blades could be out of balance, which is why you may be hearing a loud clanking sound coming from your outside AC unit. Oftentimes, clanking sounds indicate loose parts or the beginning stages of part failure. While the unit may continue to operate while this noise is present, ignoring this sound could result in more serious AC problems and costly AC repairs.To ensure the lifespan of your air conditioning unit, call Academy Air in St. Louis, MO to schedule an inspection service.

Whining Sounds

If you hear a loud whining or high-pitched noise coming from your AC unit, turn the unit off immediately and call an air conditioning repair company. Whining noises can indicate a problem with the refrigerant. A refrigerant leak can not only cause damage to the air conditioner, but it can also cause serious health problems if left untreated. High internal pressure within the compressor can also cause a screaming sound, which can be very a dangerous AC problem.
