Is your furnace making a banging sound? Don’t worry, you’re not alone. This is a pretty common issue that many of our customers have contacted us for assistance. In this article, we’ll help you understand more about what could be causing your furnace to make this banging sound and how you can fix it.

Causes of Banging Sound

There are a few different things that could be causing your furnace to make a banging sound. The most common culprit is something called “kettling.” Kettling happens when the heat exchanger in your furnace gets too hot. As it heats up, it starts to expand and contract, which can cause noise.

Another common reason for a banging furnace is a dirty or clogged burner. When the burner is dirty, it can cause a loud popping noise. And if the burner is clogged, it can create a whooshing sound.

Lastly, your furnace could be banging because of a loose panel or equipment. If something isn’t secured correctly, it can rattle and create a lot of noise.

Can the Banging be Normal?

Sometimes, the banging noise may be your furnace doing its job. However, there are a few things you can look for that may indicate a problem. For example, if the noise is accompanied by smoke or fumes, that’s a sign that something’s wrong, and you should call a professional for repair immediately.

What to Do With Abnormal Banging Noises?

The first thing to do is turn off the unit and call a professional. Trying to fix the problem yourself could do more harm than good, and it’s always best to err on the side of caution when it comes to your furnace.
