When your furnace is working properly, it should provide heat without generating too much noise. While it’s common to notice your furnace making noise as it turns on, other sounds are indicating your furnace should get immediate professional assistance.

Here are some of the most reported furnace noises and what they might be signaling. If your furnace is making a weird noise, our friendly heating pros are here to fix the problem with the best furnace repair in Mount Hope, West Virginia.

1. Furnace Making a Banging Noise

You could have a critical situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a couple of problems. These involve gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy as time passes, so that’s why it’s important to set annual furnace maintenance with Appalachian Heating. One of the jobs our pros perform during this work is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup might break your furnace’s heat exchanger, where natural gas turns into heat. Any fractures in it can discharge carbon monoxide, which is normally emitted outside. This toxic gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Appalachian Heating urges you to turn it off and reaching us at 304-707-0600. Excessive natural gas in your furnace or a ruptured heat exchanger are critical problems that require fast service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver hot air across your residence. If the ductwork wasn’t designed properly or is getting dated, it can be noisy when your furnace is heating. This might be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Appalachian Heating at 304-707-0600 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often means there’s an electrical problem, 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 is loose, you might notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or cold air around your house, and a capacitor, which triggers the motor. If either of these pieces are fading, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be due to something little, like a loose screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and calling our heating specialists at 304-707-0600 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it requires some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubricated. We are aware that maintenance frequently slips your mind, but our pros can get your furnace operating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You might also be aware of whistling while the furnace is running if a floor vent is loose. If you’ve checked your vents but are still sensing noise, Appalachian Heating can provide support. It’s critical to get loose ductwork repaired fast, as it can result in comfort problems in your house and increase your gas 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 a problem with your furnace’s blower. Turn off your furnace off instantly and reach our pros at 304-707-0600 for support.
