When your furnace is operating correctly, it should provide warm air without creating too much noise. While it’s normal to catch your furnace making noise as it begins running, other sounds are indicating your furnace should get immediate professional help.

Here are some of the most reported furnace noises and what they can mean. If your furnace is making a strange noise, our friendly heating specialists are here to help with the best furnace repair in Menomonie and western Wisconsin, Wisconsin.

1. Furnace Making a Banging Noise

You may have an urgent problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a couple of problems. These involve gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty as time passes, so that’s why it’s essential to schedule routine furnace maintenance with Halverson Brothers Inc. One of the things our professionals do during this service is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise if ignition is delayed. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can leak carbon monoxide, which is regularly emitted outside. This dangerous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Halverson Brothers Inc urges you to turn it off and contacting us at 715-352-4052. Too much natural gas in your furnace or a ruptured heat exchanger are serious troubles that should get immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver hot air around your house. If the ductwork wasn’t designed correctly or is aging, it can be noisy when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Contact Halverson Brothers Inc at 715-352-4052 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you observe 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 relies on an internal transformer to work on the proper voltage. If wires or the box isn’t tight enough, you might hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes hot or cold air around your house, and a capacitor, which starts the motor. If either of these pieces are going out, 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 related to something small, like an unsecure screw, or something major, like a broken part. In either case, we advise shutting your furnace off and calling our heating specialists at 715-352-4052 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to get your attention it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubed. We know that maintenance sometimes slips your mind, but our pros can get your furnace operating quietly again quickly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You could also hear whistling while the furnace is running if a floor vent isn’t secure. If you’ve looked at your vents but are still hearing noise, 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 drive up your energy bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket usually means there’s an issue with your furnace’s blower. Turn off your furnace off promptly and call our professionals at 715-352-4052 for support.
