Weird Furnace Noises That Indicate a Problem

The weather is finally starting to cool, and that means you’re probably relying on your furnace more and more often to keep warm. As you start to use your furnace more regularly, the wear and tear on the system will increase. That will make it more likely for problems to occur. One of the easiest warning signs to pick up on for furnace problems is strange noises coming from the system. Have a look at some of the more common noises below that indicate a problem with your system.


Your furnace moves air around your home by using a part called the air handler. The air handler is essentially a large motor with a fan attached to it. Without it, the furnace wouldn’t actually be able to heat the home. The air handler motor is put under a lot of stress during operation, so it is equipped with a number of oiled bearings to help it run more smoothly.  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 before the air handler motor overheats and burns out.


If your gas furnace is making a booming sound every time it starts up, it means that the burner assembly is partially clogged. This is caused by the buildup of carbon particles, which are a byproduct of combusting natural gas. The particles build up on the jets in the assembly until they don’t fire on time anymore. When the jets do fire, they burn through a lot of gas at once and make a loud boom. Having the assembly professionally cleaned should fix the problem.
