Unusual Furnace Sounds and What To Do About Them

Unusual Furnace Sounds and What To Do About Them

Furnaces play an essential role in the comfort of your home during the colder months of the year! When you notice that they are starting to produce some weird noises here and there, you may put it on the back burner, and sometimes that is okay! However, a properly functioning furnace shouldn’t make too much noise, especially after initially starting. The type of sound you’re hearing can help determine the exact issue with your system! Read below and determine if the sounds you are hearing come from your furnace is a cause for concern or not...

Scraping Noise 

Do you know the sound of metal grinding against metal? That is never a sound you want to hear coming from your furnace. This can usually be attributed to a broken motor mount or blower wheel and needs to be looked at ASAP, as this can cause major damage to your entire system. 

Wheezing 

A wheezing or whooshing sound could potentially be from a dirty furnace filter. If your filter is left too long without being replaced, your furnace will begin to push air through the grit. All you have to do is change your furnace filter to get rid of that wheezing noise! 

Banging, Booming, and Popping 

Does your furnace ever make a boom or pop noise when it’s first starting up? Chances are that your furnace burner is dirty and needs to be cleaned. When a furnace burner is clogged with dust or dirt it causes gas to build up and make a popping noise when the flame finally ignites. 

Whining or Squealing 

If you ever hear an unusual whining sound coming from your furnace it most likely indicates there is something wrong with your blower belt. It could be worn or misaligned. An HVAC technician can take a look at this during your next routine tune-up!
