When your furnace is running properly, it should provide warm air without generating too much noise. While it’s common to catch your furnace making noise as it starts up, other sounds are showing your furnace should get immediate professional help.

Here are some of the most reported furnace noises and what they could mean. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Menomonie and western Wisconsin, Wisconsin.

1. Furnace Makes a Banging Sound

You might have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be several problems. These range from gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty as time passes, so that’s why it’s essential to set seasonal furnace maintenance with Halverson Brothers Inc. One of the things our pros do during this appointment is clean your furnace’s burners. When this component gets dirty, you might hear your furnace making a loud rumbling noise when ignition takes more time. The subsequent gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can leak carbon monoxide, which is regularly released away from your home. This toxic gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Halverson Brothers Inc urges you to turn it off and calling us at 715-352-4052. Too much natural gas in your furnace or a broken heat exchanger are dangerous issues that should get prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver heated air around your house. If the ductwork wasn’t designed correctly or is getting old, it can make a lot of noise when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Halverson Brothers Inc at 715-352-4052 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to operate on the right voltage. If wires or the box is loose, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cooled air throughout your space, and a capacitor, which triggers the motor. If either of these components are fading, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be the result of something small, like an unsecure screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating professionals at 715-352-4052 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to get your attention it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubricated. We realize that maintenance often slips your mind, but our techs can get your furnace operating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You may also notice whistling while the furnace is running if a floor vent is loose. If you’ve examined your vents but are still hearing sound, Halverson Brothers Inc can provide support. It’s critical to get loose ductwork taken care of quickly, because it can result in comfort issues in your home and inflate your energy expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal racket typically means there’s trouble with your furnace’s blower. Turn off your furnace off right away and call our professionals at 715-352-4052 for help.
