Keep an ear out for furnace issues - how to "hear" your potential problems!

Even the most advanced, and high-tech furnaces produce some type of noise when in operation. Whether it's the sound of the furnace starting up or the air pushing through your ducts, your furnace isn't a stranger to sounds - but these noises shouldn't be keeping you up at night. If, over time, your furnace starts making noises that aren't familiar to you, it may be trying to tell you that something is amiss. Here are a few sounds our neighbors throughout Outer Banks and Raleigh should be on the lookout to ensure their furnaces are running smoothly.

Does your furnace make banging and popping noises?

Furnaces in optimal health have been known to make a few banging and popping noises now and again, representing the sound of your ducts expanding and contracting. But that's not always the reason behind these sounds. It could be that you have dirty burners or a problem with your fuel delivery system, leading to delayed ignition. In this instance, excess fuel can build up in the combustion chamber, resulting in minor explosions.

Squeals and screeches with your North Carolina furnace

A furnace that squeals and screeches is probably trying to tell you that it has a slipped or fraying belt. Generally speaking, this is a rather minor issue, but something you don't want to put off. If you ignore it for too long, it can evolve into something far more troubling.

Unwanted scraping noises

A scraping sound coming from within your heater likely means you're dealing with metal on metal. This could be the result of a jam in moving parts, or a blower wheel that has come loose from its mount.

What you should do if you hear any of these noises

Overall, each of these furnace noises signify minor issues that, while impact the output of your system, are not cause for emergency concern. That being said, we always recommend you contact your local heating and cooling specialist as soon as you hear these sounds. The quicker you act, the more likely your specialist can remedy the problem before it becomes a larger issue.
