Your Furnace Makes a Loud Banging Noise When it Starts

If you hear a loud banging or booming noise when you start up your furnace, it could be caused by expanding and contracting ducts. It could also indicate dirty burners or a defective gas valve. It’s probably a good idea to contact a professional to determine the exact cause.

Your Furnace Makes a Rattling Noise When it Shuts Off

If you hear a rattling sound when your furnace turns off, it is most likely caused by the metal parts cooling down inside the furnace.

Your Furnace Makes a Clanging Noise

Clanging noises coming from your furnace usually indicate an issue with the pipes. The pipes sometimes contract as they cool down, causing this unusual noise.
