Common Furnace Noises That Could Mean Issues Are Brewing

Do you have a furnace in your home to keep you warm during the winter? We thought you might—most people grew up in homes with furnaces. Even if your current furnace is the first one you’ve ever had, you probably already have a good idea of the sounds it makes when it’s operating. Make sure you pay attention to these sounds, because the moment they change into something you haven’t heard before, it usually indicates a serious problem is brewing in the furnace cabinet that could develop into a major repair issue, a breakdown, or a safety hazard.

The moment you suspect that there is something awry in your furnace, call for professionals to investigate and do the necessary repairs. In Independence, KY, heating repairs from Greater Comfort Heating & Air Conditioning, Inc.® will ease your worries. We’ve served Northern Kentucky since 1988 and have the experience to get your repairs done fast and right.

Listen for these unusual furnace noises:

Loud clicking: This is the most important one to pay attention to. The source could be as simple as loose bolts on the furnace cabinet. However, if you have a gas-powered furnace, clicking noises from inside the cabinet might indicate cracks in the heat exchanger. Because this can lead to a toxic carbon monoxide leak, shut off the gas to the furnace and call for professional help immediately.

Clanking: This is likely due to a loose or cracked blower fan motor belt. If this belt becomes dislodged or broken, it will begin striking other components in the cabinet and lead to further damage. Even if you’re familiar with how to change the fan belt on a car engine, don’t try to fix this issue yourself. (Trust us, it’s not the same.)

Groaning and squealing: The motor bearings have gotten dirt on them or they have worn down. The bearings will need replacing before the motor itself burns out and requires a costlier replacement.

Rumbling or booming: For a gas-powered furnace, this indicates grime along the burner where the gas jets ignite to heat up the combustion chamber. You will need to have professionals remove and clean the burner, or else the gas jets will not be able to draw sufficient oxygen to ignite.

Furnaces are devices that you should never attempt to repair on your own: whether electrical or gas-powered, they pose health hazards to anyone who tampers with them without the proper tools and experience.
