When your furnace is running like it should, it should deliver warm air without making too much disruption. While it’s normal to hear your furnace making noise as it begins running, other disruptions are indicating your furnace needs 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 professionals are here to fix the problem with the best furnace repair in Wisconsin Rapids, Wisconsin.

1. Furnace Making a Banging Noise

You could have a critical issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a couple of problems. These involve gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy as time passes, so that’s why it’s essential to book yearly furnace maintenance with Rapids Sheet Metal Works Inc. One of the tasks our professionals do during this appointment is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise if ignition is delayed. The subsequent gas buildup might crack your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can emit carbon monoxide, which is ordinarily emitted away from your home. This dangerous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Rapids Sheet Metal Works Inc advises turning it off and contacting us at 715-301-0256. Too much natural gas in your furnace or a fractured heat exchanger are hazardous troubles that necessitate prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver warm air across your home. If the ductwork wasn’t designed right or is getting old, it can make a lot of noise when your furnace is on. This can be the problem if your furnace makes a banging noise when it shuts off. Contact Rapids Sheet Metal Works Inc at 715-301-0256 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually means there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to operate on the proper voltage. If wires or the box isn’t tight enough, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves hot or cooled air around your space, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be the result of something small, like an unsecure screw, or something serious, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating specialists at 715-301-0256 for help.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to get your attention it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be greased. We know that maintenance frequently slips your mind, but our technicians can get your furnace running quietly again fast.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You might also be aware of whistling while the furnace is operating if a floor vent isn’t tight. If you’ve examined your vents but are still hearing noise, Rapids Sheet Metal Works Inc can help. It’s essential to get loose ductwork repaired fast, because it can make comfort troubles in your residence and drive up your utility expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal noise frequently means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and call us at 715-301-0256 for support.
