Why does my air conditioner make noise even when it's off?

Your air conditioner can make noises when it’s off due to parts inside it expanding or shrinking because of temperature changes, the liquid used to cool the air moving around, or problems with the air passages. These sounds are usually okay but sometimes can mean there’s an issue that needs looking into.

Can these noises indicate a serious issue?

Yes, even though many times these sounds are nothing to worry about, if your air conditioner keeps making loud or strange noises, it could be a sign of a bigger problem. Things like parts not being tight enough or issues with the air passages could get worse if not fixed.

How often should I have my air conditioner serviced?

You should get your air conditioner checked by a professional at least once every year. This helps make sure it’s working right and can help stop problems that might make it noisy or less efficient at cooling your house.
