When your furnace is working like it should, it should give warmth without creating too much disruption. While it’s expected to notice your furnace making noise as it begins running, other noises are indicating your furnace needs immediate professional assistance.

Here are some of the most reported furnace noises and what they could be signaling. If your furnace is making an odd noise, our friendly heating professionals are here to assist with the best furnace repair in Wisconsin Rapids, Wisconsin.

1. Furnace Making a Banging Noise

You may have an urgent situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be several problems. These involve gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy as time passes, so that’s why it’s essential to schedule seasonal furnace maintenance with Rapids Sheet Metal Works Inc. One of the tasks our techs complete during this work is clean your furnace’s burners. When this part gets dirty, you could hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can emit carbon monoxide, which is regularly vented outside. This toxic gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Rapids Sheet Metal Works Inc recommends turning it off and contacting us at 715-301-0256. Significant natural gas in your furnace or a ruptured heat exchanger are hazardous problems that should get immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver warm air throughout your residence. If the ductwork wasn’t put in properly or is aging, it can be noisy when your furnace runs. This could be the problem if your furnace makes a banging noise when it shuts off. Call Rapids Sheet Metal Works Inc at 715-301-0256 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the proper voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or cold air throughout your rooms, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace turns 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 critical, like a broken part. In either case, we recommend shutting off your furnace and calling our heating pros at 715-301-0256 for assistance.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be greased. We are aware that maintenance frequently slips your mind, but our pros can get your furnace running quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also hear whistling while the furnace is running if a floor vent is loose. If you’ve checked your vents but are still sensing noise, Rapids Sheet Metal Works Inc can assist you. It’s critical to get loose ductwork taken care of quickly, because it can make comfort problems in your home and inflate your heating bills.

6. Furnace Making a Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise typically means there’s an issue with your furnace’s blower. Shut down your furnace off now and call us at 715-301-0256 for assistance.
