Call for Repairs If Your Furnace is Making These Noises

Dependable Service Since 1926

You’re going to be using your furnace more and more often as we get into heating season, which means more strain on the system and a higher chance of problems developing. It’s important that you be able to identify furnace problems early, so that you can limit damage to the system. One of the easiest ways to identify problems is to listen for strange noises coming from the furnace. Read on for some of the more common noises that indicate a furnace problem.


If you hear grinding coming from your furnace, it means your air handler is in trouble. The air handler is the part of the furnace that circulates air throughout the ductwork during operation. In order to compensate for the friction created during operation, the air handler is equipped with lubricated ball bearings. These bearings wear down over time, causing the friction on the air handler to increase and producing a loud grinding sound. If you hear this occurring, call for repairs immediately before the air handler burns out.


The burner assembly is the part of the furnace that ignites natural gas in order to generate heat. Over time, carbon particles collect on the burner assembly jets. Eventually, the burner assembly will become so clogged that it starts to ignite later than it should. When the assembly finally ignites, it burns through all of the excess gas at once and generates a loud booming sound. Getting your burner assembly cleaned should take care of the problem for you. Make sure you schedule it quickly, though, before the assembly gets too clogged to ignite at all.
