How to Stop Furnace From Banging

Cars make noise. Ovens and dishwashers produce mild sounds when running. Just about any appliance in your home makes noise, even your furnace has a low humming sound. When should the noise from your furnace be a cause of concern? 

Banging Noises Coming from Your Furnace Are Not Normal

Loud, unusual noises coming from your furnace should always be checked out. Accepting the clanging or banging as normal will cost more in repairs in the long run and may even cause your furnace to fail completely. 

Causes & Cures for Furnace Banging Noises

There are a couple common reasons why your furnace is banging

If the banging happens when the furnace turns on and off, the problem could be increased pressure in your ductwork. The pressure changes inside the ducts when the air handler turns on, causing the ducts to pop or bang, often due to clogged or dirty filters or even vents being closed. A simple fix is to schedule regular furnace maintenance before every heating season begins.

Neglecting regular furnace tune ups can also lead to dirt or soot building up on the furnace’s burners. When the buildup is excessive, the ignition of the furnace is delayed which may lead to a banging sound. Over time, this causes extra wear and tear on the furnace and may lead to a cracked heat exchanger. 

In addition to scheduling regular furnace maintenance with a trusted company like Merts Heating & Air Conditioning, there are two additional steps you can take to make sure your furnace runs efficiently all season long:

  1. It’s a good idea to change your filters monthly during the heating season to make sure air flows freely into the furnace. 
  2. Keep air vents open and be sure furniture or other objects are not obstructing the flow.
