Why Is My Furnace Making a Banging Noise?

Has your furnace starting talking to you or have the sounds of your furnace changed?

Has your furnace starting talking to you or have the sounds of your furnace changed? Furnaces can be noisy, however; if that noise gets louder over time, and sounds like someone or something banging to try to get out of your furnace, there is likely something wrong. We are going to help you answer the question, “Why is my furnace making a banging noise?”

Reasons Your Furnace Could be Making New Sounds

Your Buffalo New York furnace is essential, especially as we head into the winter season. While there may not have been any indications of issues when you turned on your furnace for the season, over time and use, you may start to notice things that indicate there could be a problem.

Typically, when your furnace starts to make new sounds, especially a banging noise, this is a sign that something is not right. If the banging sound occurs only when your furnace first starts or right after it stops blowing hot air, the noise probably is caused by expansion and contraction and it not an indication of a problem; however, if the noise continues as the furnace is running, there is likely an issue.

Let’s review some reasons for your furnace making a banging noise.

Fan Issues: The fan on your furnace is what pushes the heated air throughout your home. Sometimes a blockage in the fan can cause it to make noises. Having your furnace tuned and cleaned can help to prevent this issue. There are instances when your fan could be going out, causing the banging sound.

Dirty Burners: Dirty furnace burners keep the burners from igniting properly and can cause a buildup that will create a banging noise. This is basically a mini-explosion in the furnace, as the furnace is not able to function as it should. This issue needs to be addressed as soon as possible to avoid more costly repairs.

Air Duct Problems: Rattling, vibrating, knocking/banging, or whistling sounds coming from your HVAC system usually mean that your ductwork has something loose, a hole, or disconnected joints, amongst other things. If your HVAC system is making new loud noises when running, there could be an issue with your ductwork.

Regardless of why your furnace is making a banging noise, it is not something you want to listen to all winter and is not something that should go without being addressed. While the loud noises may not be a major issue, there could be something critical causing the distracting sounds.
