Any time you hear a new noise coming from your furnace, it’s an indication that there is something wrong with the system. When the heating system starts making a banging sound, it could be a sign that the main blower or combustion blower is damaged or malfunctioning.

Another possible reason for the new sound could be a delayed ignition. It’s hard to diagnose the exact issue without having a professional technician thoroughly investigate the system. We never advise homeowners to try and diagnose or fix these types of furnace problems. Not only is it dangerous, but you could actually cause more damage to the furnace.

If the furnace has always made a banging sound, it’s likely not even a heating system issue but incorrectly sized ductwork. Expanding and contracting air ducts can make a loud bang or pop that can be confused as originating from the furnace. If this is the case, you’ll need a professional to evaluate the ducts and make a recommendation on possible solutions.
