Why is my AC Making that Noise?

Are you hearing new and odd noises coming out of your air conditioner lately? Typically when your AC is running correctly you wont hear it make noises that cause concern. It is quiet enough that people often will not think about the AC because it is functioning normally. Getting your annual maintenance done to your air conditioner will help curb these issues. There are some normal noises. Your compressor will make a slight hum when it is on. You will often hear the air move through the ducts because they expand and contract sometimes. When your AC starts to make other noise it typically is signalling that there is a problem. When your air conditioner gets older, things tend to start to wear. When you hear a thumping sound it typically is an issue with a loose or worn out belt. Your air conditioner might start to whine because of reduced airflow due to a clogged air filter. If you hear rattling you should check the bolts on the cover plates to make sure they didn’t come loose. Sometimes all it takes is to tighten the bolts to make it stop. If your unit happens to be whistling, you might have leaky seals. It is usually coming out of cracks in the duct work. Screeching might be a worn out fan belt in the inside unit. This can be fixed by a qualified technician like the ones at Bartlett Heating and Air. A thud could be something flying around the inside of the unit like a belt that came loose or a fan blade that got bent. One last sound that is heard a lot is a buzzing sound. The buzzing is usually your capacitor acting up. Earwigs like to climb into them which stops it from functioning correctly so it buzzes really loud. To lessen the chance of this happening you should spray bug spray around your outside unit. Bartlett Heating and Air can inspect all air conditioner noises and help you fix them so call us today!
