Weird Furnace Noises You Should Listen for

Furnaces make all kinds of noises during operation. You’re probably familiar with the kinds of noises that your furnace tends to make. However, some furnace noises can indicate a problem with the system. If your furnace starts to make unusual noises, you should call for repairs as soon as possible. Let’s take a look at some common furnace noises that indicate repair needs.

Booming

If your furnace sounds like a cannon firing when it starts up, it probably means that you have a dirty burner assembly. Carbon particles build up on the furnace burner assembly over time, eventually clogging the jets and causing them to fire later than they should. When the jets finally do ignite, they burn through a lot of excess gas and cause a deep booming sound. Having the burner assembly cleaned should fix the problem. Best to do it quickly, though, as the longer the particles buildup the more likely it is that they will completely clog the assembly.

Grinding

Furnaces use air handlers to move air around the house. The air handler is essentially a large motor with a fan attached to it. The fan uses oiled bearings to cope with the friction generated during operation. These bearings wear down over time, however, which produces a loud grinding sound. If the bearings are not replaced in time, the air handler motor will overheat and burn out. Call for repairs as soon as you hear this sound coming from your furnace. It is far cheaper to replace worn out bearings than it is to replace a burned out air handler motor.

If your furnace is making any kind of strange noise, call Goettl Good Guys Air Conditioning. We offer a full range of furnace repair services.

I called Goettl to get a second opinion on a/c repair options or replacement. Peter Medelez conducted a very thorough system check and confirmed all the same issues previously identified but found an additional issue; tipping the scale to full replacement. We appreciated his professionalism and knowledge: answering all our questions and explaining the issues and options. We ultimately chose Goettl for the replacement option due to their price and professionalism.

William and Cameron were knowledgeable, friendly, professional, respectful and put on plastic booties over their shoes when they came into the house. Our pets were comfortable with them and that says a lot. We will definitely ask for them again in the future if our AC has any issues.
