Listen for These Furnace Noises That Indicate a Problem

As you use your furnace more and more often this season, you’re going to increase the amount of stress on the system. This makes it more likely for problems to occur. If you want to keep your furnace in the best possible condition, you need to make sure that you can identify problems as quickly as possible. One of the best ways to identify problems early is to listen for strange noises coming from your furnace. Read on to find out more about the various noises that indicate a furnace problem.


Your furnace circulates air throughout the home during operation using a device called the air handler. In order to cope with the amount of friction generated during operation, the air handler motor is equipped with a handful of oiled bearings. These bearings wear down over time, causing the friction on the system to increase and producing a loud grinding sound. If you hear this sound, call for repairs immediately. Otherwise, the motor might overheat and burn out.


If you’re using a gas furnace, and it’s making a deep booming sound upon starting up, it likely means that you have a dirty burner assembly. The burner assembly is the part of the system that burns natural gas in order to produce heat. Over time, carbon particles form as combustion byproducts and collect on the burner assembly jets. This eventually clogs the jets to the point where they won’t ignite on time. When the jets finally do ignite, they burn through all the excess gas at once. This is what generates the booming sound. Get your burner assembly professionally cleaned in order to solve this problem.
