Why is My Furnace Making That Noise?

During the course of every day operation your furnace will make some normal sounds. But if you start to notice new or strange sounds coming from your furnace, it could indicate serious and even dangerous problems.

Uncommon Furnace Noises:

These are some furnace noises you should watch out for.


  • Rattling – If your furnace is making a rattling sound it could mean that carbon monoxide is leaking into your home. Your furnace’s heat exchanger is responsible for heating the air and also exhausting the dangerous combustion fumes that result from burning fuel. If the heat exchanger cracks it could start making a rattling sound and leaking carbon monoxide into your home.
  • Rumbling – This is another dangerous sound because it could mean that there is unburned fuel in the furnace combustion chamber.
  • Knocks, pops and bangs – Depending on what your ducts are made out of, they could make a number of different noises as they heat up and expand.
