This blog will explore the common noises furnaces make, what they mean, and when you should act.

Common Furnace Noises and What They Mean!

Furnaces make noise, but certain sounds could mean something is wrong. Here’s what to listen for:

• Rattling: This sound could be caused by loose parts or ductwork. If it’s minor, it may just be a loose screw, but if it continues, it could mean something more serious, like a cracked heat exchanger.

• Banging: A loud banging noise usually happens when gas builds up before igniting. When the gas finally ignites, it creates a small explosion. Dirty burners or wrong air-to-fuel mix can cause this.

• Whistling: A high-pitched whistling sound often happens when airflow is blocked, usually by dirty filters or leaks in the ductwork.

What Causes These Noises?

Rattling

• Loose Parts: Over time, screws or panels can loosen as the furnace heats up. Tightening them might fix the problem.

• Ductwork: If ducts aren’t properly connected, they can rattle when air flows through. Make sure ducts are secure.

• Serious Issues: If rattling doesn’t stop after fixing loose parts, it could point to internal problems, like a cracked heat exchanger.

Banging

• Delayed Ignition: If gas builds up before it ignites, it can cause a loud bang when it finally does. Dirty burners are a common cause.

• Wrong Air-Fuel Mix: If the air and gas mixture isn’t right, it can lead to banging. Cleaning the burners may help, but sometimes it requires a professional to adjust the settings.

Whistling

• Clogged Filters: Dirty filters restrict airflow, causing a whistling sound. Change filters every 2-3 months to keep the furnace working well.

• Duct Leaks: Small holes in the ducts can cause whistling. Check for leaks and seal them up.
