When your furnace is operating correctly, it should deliver warmth without creating too much sound. While it’s common to catch your furnace making noise as it begins running, other disruptions are showing your furnace requires immediate professional support.

Here are some of the most frequent furnace noises and what they can be indicating. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Greensburg, Indiana.

1. Furnace Makes a Banging Sound

You might have a serious situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be several problems. These include gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over time, so that’s why it’s essential to set seasonal furnace maintenance with Wallpe Heating & Cooling. One of the tasks our professionals perform during this service is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes longer than normal. The ensuing gas buildup can break your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can leak carbon monoxide, which is ordinarily emitted outdoors. This hazardous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Wallpe Heating & Cooling urges you to turn it off and calling us at 812-663-7252. Too much natural gas in your furnace or a cracked heat exchanger are critical issues that should get immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver hot air throughout your home. If the ductwork wasn’t installed properly or is aging, it can make a lot of noise when your furnace is heating. This can be the problem if your furnace makes a banging noise when it shuts off. Call Wallpe Heating & Cooling at 812-663-7252 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace depends on an internal transformer to operate on the correct 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 works with a blower motor, which distributes heated or chilly air throughout your residence, and a capacitor, which turns on the motor. If either of these components are failing, 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 the result of something minor, like an unfastened screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and getting in touch with our heating pros at 812-663-7252 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to alert you it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubed. We are aware that maintenance sometimes slips your mind, but our professionals can get your furnace operating quietly again fast.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You may also notice whistling while the furnace is on if a floor vent isn’t tight. If you’ve checked your vents but are still noticing noise, Wallpe Heating & Cooling can provide support. It’s critical to get loose ductwork taken care of without delay, since it can result in comfort problems in your residence and inflate your gas costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal racket typically means there’s trouble with your furnace’s blower. Switch off your furnace off promptly and contact our professionals at 812-663-7252 for assistance.
