Why is My Furnace Making a Banging Sound?

banging sound

The only reason you should notice that your furnace is on is by the warm air circulating throughout your home—it should not be making any loud noises. If your heating system starts suddenly making a banging sound when turning on or operating, it’s important to call for professional furnace service.

There could be a few reasons why the furnace is making a banging sound:

  • The main blower or combustion blower could be damaged or malfunctioning.
  • A delayed ignition could be causing a small explosion.
  • Undersized ductwork could be expanding and contracting.

A heating technician will be able to identify the source of the sound, diagnose the issue and provide you with a solution. We never advise homeowners to investigate furnace issues like this or attempt home repairs. It can be extremely dangerous and you could cause more damage to the system.

Preventative Furnace Maintenance
Scheduling yearly heating system appointments can help prevent furnace issues. During a preventative maintenance visit, a trained technician does an in-depth furnace safety inspection and performance evaluation with any issues that could lead to furnace sounds being identified and fixed.

If you are having problems with your heating system, especially new furnace sounds, it’s important to contact certified heating specialists like those at Team Harding. Our technicians are licensed professionals that will take the time to identify the issue, clearly explain the problem and solution, and provide prompt repair services.
