As a homeowner in Hendersonville, NC, you recognize the usual sounds that your home makes. However, if you begin hearing noises coming from your furnace, they can be a serious cry for help from your home’s heating system. Here are some of the ways your furnace is telling you that it needs to be repaired or replaced.

Rumbling Sounds

Ideally, your furnace operates in near or complete silence. If you begin hearing a rumbling sound coming from your furnace, you probably have an issue with the system’s burner. Burner issues can be incredibly serious, so you should turn the furnace off and contact a professional furnace repair tech if you notice a constant rumbling sound.

Squealing Sounds

The most likely culprit for the squealing sound coming from your furnace is a loose or torn fan belt. While on the surface this may seem like a minor issue, a fan belt that completely comes loose or tears apart can wreak havoc on the internal components of your furnace. A squealing sound is another sign that you need to turn your furnace off and call a professional for repair.

Thumping Sounds

If your furnace begins thumping, it means that there is something loose inside the system. While it is most likely the blower wheel, the system’s motor can also work itself loose over time. Both are serious issues that require professional repair.

Scraping Sounds

A blower wheel that works itself loose can also produce a scraping sound as the metal parts of the wheel begin rubbing against the metal housing that encapsulates it. Not only will this sound be annoying, but the blower wheel may also do serious damage to the wheel housing and other parts that surround it.

Anytime you hear a strange sound coming from your furnace, you should call a professional furnace repair technician for help. Call Mountain Air Mechanical Contractors today to find out more about our services, including furnace repair or replacement.
