A Guide to Buzzing Sounds Coming From Your Furnace
Although a low hum is normal when your furnace is running, if your furnace is making a buzzing noise, there could be a problem. Distinct buzzing or loud humming indicates an issue that needs to be fixed:
- Blower fans are dirty
- Failing or damaged blower fan motor
- Damaged capacitator
- Loose components
- Damaged ductwork
- Loose transformer box
Because a buzzing can indicate a range of problems, it’s best to have a professional like those at Blue Frost inspect your furnace and repair it if necessary.
Other Sounds & What They Mean
Keep an ear out for these other sounds that may suggest a problem with your furnace that needs to be addressed:
- Loud bang: If you hear a loud bang when your furnace kicks on, it could indicate a gas buildup in your system due to dirty burners.
- Banging or booming noises: Air ducts are undersized, or the air filter is clogged.
- Scraping of metal on metal: This can indicate a significant problem with your blower wheel that needs to be repaired.
- Rattling: This can be as simple as a loose screw or panel or could mean a crack in the furnace’s heat exchanger.
- Rumbling: You’ll notice this if you haven’t used or maintained the furnace in a while due to dirty burners or a problem with your pilot light.
- Whistling: This can indicate gaps in your vents or duct blockage.
