Why is my HVAC making noise?

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

However, hearing weird 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 too much racket increases sound pollution. While noise might not necessarily affect energy efficiency, it can influence comfort in your house.

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