Why Is My Furnace Making a Loud Noise?

Home » Why Is My Furnace Making a Loud Noise?


There are several reasons why a furnace can start making loud noises, and they all come from some level of furnace malfunction, as a healthy furnace is a quiet one.

Clicking Noise

Indicate a problem with the furnace’s ignition system and should be checked out by a professional

Banging, Popping or Rattling Noise

This can mean there is a problem with the blower assembly, the motor or the furnace of the furnace.

If you hear rattling noises, something is likely loose and needs attention by a professional. If you hear sudden loud banging, it’s likely that a part has broken and become disconnected, and immediate professional services are required.
