When your furnace is operating like it should, it should provide heat without generating too much sound. While it’s normal to hear your furnace making noise as it begins running, other noises are signaling your furnace needs immediate professional support.

Here are some of the most common furnace noises and what they could be indicating. If your furnace is making an odd noise, our friendly heating specialists 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 serious issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a couple of problems. These range from gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over time, so that’s why it’s critical to book routine furnace maintenance with Rapids Sheet Metal Works Inc. One of the jobs our pros complete during this service is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise after ignition takes more time. The following gas buildup might crack your furnace’s heat exchanger, where natural gas transforms into warmth. Any fractures in it can emit carbon monoxide, which is regularly emitted outside. This toxic gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Rapids Sheet Metal Works Inc recommends turning it off and reaching us at 715-301-0256. Too much natural gas in your furnace or a ruptured heat exchanger are serious troubles that necessitate prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver warm air throughout your home. If the ductwork wasn’t installed right or is getting old, it can be loud when your furnace is on. This could be the issue 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 hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the right voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or chilly air around your home, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace starts.

3. Furnace Makes Rattling Sounds Like Something Is Loose

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 component. In either case, we urge you to shut your furnace off and contacting our heating specialists 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 tell you it could use some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be greased. We are aware that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again fast.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You may also notice whistling while the furnace is working if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing whistling, Rapids Sheet Metal Works Inc can assist you. It’s essential to get loose ductwork fixed fast, as it can make comfort problems in your residence and drive up your energy bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal noise often means there’s a problem with your furnace’s blower. Switch off your furnace off now and reach our professionals at 715-301-0256 for support.
