Common AC System Noises
Every air conditioning system makes a certain amount of noise. Most people, for example, find the sound of air whooshing through the ductwork rather soothing. The gentle hum of on outdoor condensing unit might even help you fall asleep.
Those are the good noises.
Then there’s the clanking, banging and grinding sounds that make you wonder if a monster is trying to break into your home. Far from soothing.
What can cause that kind of racket? Let’s have a look.
Outdoor Condensing Unit – Your outdoor condensing unit contains a compressor which, in turn, includes a fan. Over time, parts can loosen and bump into the fan, or the fan move and do some bumping of its own.
Clanking and Banging from the Inside – Your AC system also includes an indoor heat exchanger and that, too, contains a fan. Maybe a part has come loose or perhaps your bearings need to be lubricated.
Dirty Ductwork – Your air ducts should be cleaned every few years to help maintain sufficient air flow and cleaner indoor air. Dirty, clogged air ducts restrict air flow which cause internal banging and popping noises.
Overgrown shrubs – Dense landscaping can inhibit your condensing unit from releasing heat. That makes your system work harder to keep you cool. Overgrown plant life bumping into the unit’s fan can cause a ruckus of its own.
