Furnace Noises & Sounds: A Guide

Your furnace likely produces a low hum, meaning it’s powered on and operating. But what if the noise is abnormal and much more noticeable? If issues arise with your furnace, whether a broken part or a needed cleaning, the problem should be tackled immediately to avoid the risk of a total system breakdown.

Some of the noises you may notice include:

• Banging
• Buzzing
• Scraping
• Rattling
• Whistling

Causes of Noises Coming From Your Furnace

So, what exactly causes a furnace to generate loud noises?

• Banging: Banging could indicate a gas buildup in your unit due to dirty burners. It could also indicate a clogged air filter or undersized air ducts. 
• Buzzing: Loud humming or buzzing could mean there’s an electrical issue present.
• Scraping: This is likely due to an issue with your blower wheel. If it becomes unaligned, it can make a metal-on-metal noise. 
• Rattling: Loose screws, panels, or a cracked heat exchanger may cause rattling.
• Whistling: Gaps in your vents or ductwork, whether small or large, can produce whistling due to air blowing through them.
