Is Your Furnace Making These Ominous Noises?

With weather cooling down to the point that it’s finally time for you to turn on your heater—at least at night—hopefully you have a system that is ready to do its job effectively and efficiently. If, however, you notice noises that it probably should be making, then it’s imperative that you don’t ignore the problem or potential problem. Odd sounds echoing from your furnace are typically early signs of developing trouble.

To reduce the risk of expensive repairs or a complete shutdown, it’s important that you get in touch with a professionally trained HVAC professional as soon as possible. Your furnace trouble might be minor, but even the smallest problems can begin to cause wear and tear on your heating system that will lead to further problems, or even safety hazards. So, what noises should you listen for?

Clanking or Squealing

The culprit in this case is very likely a cracked or loose blower motor fan belt. This is a severe issue that needs immediate attention, since a loose belt can and will damage other components.

Loud Clicking

This sound may originate from something as minor as loose outside panels that need to be screwed down. But if you discover the panels are secure yet still hear the noise, then there might be a crack in the heat exchanger. This is a big problem that could pose health and safety risks, so be sure to shut off your system and call one of our professionals right away should you notice this.


This is probably a problem with the motor bearings. If they’ve become worn down, they will make this noise and will need replacement. Be sure to get this done ASAP to avoid full motor replacement.


If you hear a rumbling sound deep inside your furnace, it could be the sign of a dirty burner. Ensure that you schedule regular maintenance in order to avoid this.
