Why is my HVAC making noise?

It’s normal for your comfort system to make some noise as it operates. There are a couple of details that influence its sound level, such as age and insulation.

However, hearing strange or loud noises might mean a possible problem with your unit. If you don’t fix it, there may be major (and expensive) effects later on.

Equipment that makes a large amount of racket increases sound pollution. While noise might not necessarily affect energy efficiency, it might affect comfort in your residence.

Comfort systems made recently are quieter than previous models. However, it’s wise to look for sound levels for your new air conditioner or heat pump, particularly if it’s located near your bedroom or living room.
