It’s normal to notice that your air conditioning unit is running – you should hear it. However, strange sounds from the AC unit that do not go away could indicate the need for air conditioning repairs. Below are six AC noises that may require service by an experienced Granite City, IL heating and cooling company. If what you’re hearin’ has you fearin’, contact your local pros for the repairs you need!
A buzzing sound coming from your AC unit can mean one of several things. There could be loose parts in the unit, or your air filter might need to be changed. The fan motor or blower could also be the source of the problems. Out of balance or loose parts could be causing the buzzing. Because a buzzing sound could mean one of many AC problems, we recommend calling a professional to inspect the air conditioning unit.
A banging sound could mean that the compressor needs to be replaced. It can also mean that a part is loose or broken. Again, a banging sound could mean you need AC repairs.
Squeals, squeaks, and rattles, many times, indicate a problem with the fan. Blower motors emit loud squealing sounds when they are about to fail. Also, the blower wheel and housing will emit this sound when they are malfunctioning. If the sound continues, have an AC professional investigate further.
The outdoor fan, indoor blower, or the unit’s blades could be out of balance and causing a clanking sound. However, clanking can also be caused because the parts inside the sealed unit are loose or beginning to fail. While the unit may continue to operate while clanking, ignoring this sound could result in more serious AC problems and costly AC repairs.
Clicking when you turn the air conditioning unit on or off is usually normal. However, if the clicking sound continues, this could be a sign of a failing thermostat or a defective control. An AC repair technician should be called to perform service and assess the problem.
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 cause damage to the air conditioner, but it can also cause serious health problems. High internal pressure within the compressor can also cause a screaming sound, which can be very a dangerous AC problem. Call an air conditioning repair company immediately.
