Problems That Cause A Noisy Furnace

Is It Normal To Have A Noisy Furnace?

If your furnace is an old model, then it could be considered normal.

But if the noise seems to never stop and is getting louder and louder every time, then it is not something that you should ignore. And if your furnace is a new one, then hearing strange sounds is definitely unusual.

Noisy Furnace

It is then important to know what is causing the noise and what can be done to solve it. To avoid further dangers, it is best to let a qualified HVAC professional like the professionals at Guardian Heating & Air Conditioning to inspect your furnace for furnace repair and installation in Centennial, Colorado.

Here are some different sounds you may encounter that could mean your furnace needs repairs and professional services.

Scraping Sounds

Hearing loud scraping noises like metals rubbing each other is never normal. Turn off the furnace immediately.

Possible Causes:

  • The blower wheel is loosened and is hitting the blower casing
  • A broken motor mount

Whistling Noises

Whistling noises generally have something to do with airflow.

Possible causes:

  • Gaps in the duct
  • Dirty or clogged filters
  • Too small of ducts

Loud Banging Noises

Possible causes:

  • Dirty furnace burners
  • Air ducts that are expanding and contracting

High-Pitched Squealing Noises

Possible causes:

  • Blower belt is loose
  • Shaft bearings need lubricated
  • Blower motor malfunctioning

Rattling And Vibration

Possible causes:

  • Loose ducts need screwing
  • The furnace needs something underneath such as a cork or rubber pads

If you have a small budget and need to save up, some fixes can be done on your own.

However, if there are any small flames or sparks with your noisy furnace, do not attempt to do any fixes by yourself as you may endanger yourself, your loved ones and your home.
