If you hear your furnace making strange noises, do you know if they signal the need for repairs or not? The professionals at Cowboy’s Heating & Air in Farmersville, OH, offer furnace repair services and often help customers differentiate between sounds that are serious and those that aren’t. Here, they discuss five noises that signal the need to call a professional. 

5 Sounds That Signal the Need for Furnace Repairs

1. Banging & Popping

When air expands and contracts in the ducts, you’ll hear a bang or pop. Continued banging and popping could mean your furnace burners are dirty, which reduces the appliance’s efficiency. Routinely clean the built-up debris around the burners to keep your furnace from banging and popping.

2. Squealing

A squealing furnace could mean nothing more than a loose blower fan belt; however, it could also mean your motor is malfunctioning. Regular inspection of your blower fan belt for signs of wear and tear can prevent squealing from belts. You should also lubricate your motor on a regular basis to keep it from squealing.

3. Scraping

Scraping is a noise commonly made by furnaces. This is a serious sound, so you should turn off your furnace right away. It could be coming from the motor or blower wheel scraping against the casing. If the blower wheel came loose and no damage was done, it can be put back in place and re-tightened. If the blower wheel has broken, it’ll need to be replaced.

4. Whistling

A whistling furnace probably means you have dirty or clogged air filters. Replacing your filters every one to three months will ensure you never hear whistling again.

5. Constant Clicking

Hearing clicking when you first turn on your furnace is normal. It’s the sound of the ignition coming on. But if the clicking continues, and your furnace blower turns on and then off again, you need to call a trained heating professional. Clicking could signal your sensor needs to be checked and cleaned.
