Why Is My Furnace Making Weird Sounds?

Furnaces are important and helpful this time of year, but they are not perfect and can sometimes be a nuisance.

  • Loud Banging Sound

When you hear a banging sound coming from your Furnace, it is usually attributed to the fact there is a delay in your furnaces start-up. In other words, this is an indication that your furnace’s gas burners are not igniting on time. When this issue occurs, it can usually be tied back to your furnace being clogged or dirty. Once a banging noise is established, look exterior and interior of your furnace. If you have experience cleaning a furnace, then go ahead and tidy it up.
