When your furnace is running properly, it should deliver warmth without creating too much disruption. While it’s normal to hear your furnace making noise as it turns on, other disruptions are signaling your furnace requires immediate professional assistance.

Here are some of the most reported furnace noises and what they could mean. If your furnace is making a strange noise, our friendly heating specialists are here to fix the problem with the best furnace repair in South Beloit and Belvidere, Illinois.

1. Furnace Makes a Banging Sound

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

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty as time passes, so that’s why it’s important to schedule seasonal furnace maintenance with Fleming Heating & Air Conditioning Inc. One of the things our techs do during this appointment is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise when ignition is delayed. The resulting gas buildup may break your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can emit carbon monoxide, which is ordinarily vented outdoors. This toxic gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Fleming Heating & Air Conditioning Inc advises turning it off and reaching us at 877-389-2465. Too much natural gas in your furnace or a fractured heat exchanger are hazardous problems that should get fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move heated air throughout your house. If the ductwork wasn’t installed right or is getting old, it can make a lot of noise when your furnace is heating. This may be the case if your furnace makes a banging noise when it shuts off. Call Fleming Heating & Air Conditioning Inc at 877-389-2465 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

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

Your furnace relies on an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or chilly air around your residence, and a capacitor, which triggers the motor. If either of these components are fading, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be due to something minor, like a loose screw, or something major, like a broken part. In either case, we advise shutting your furnace off and calling our heating specialists at 877-389-2465 for support.

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 attempting 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 might need to be greased. We are aware that maintenance sometimes slips your mind, but our technicians 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 could also hear whistling while the furnace is running if a floor vent isn’t secure. If you’ve checked your vents but are still sensing noise, Fleming Heating & Air Conditioning Inc can help. It’s critical to get loose ductwork taken care of without delay, as it can result in comfort issues in your house and drive up your utility expenses.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal racket usually means there’s trouble with your furnace’s blower. Shut down your furnace off promptly and reach our pros at 877-389-2465 for assistance.
