When your furnace is working correctly, it should deliver warm air without generating too much noise. While it’s expected to hear your furnace making noise as it starts up, other noises are showing your furnace should get immediate professional support.

Here are some of the most frequent furnace noises and what they could be signaling. If your furnace is making an atypical noise, our friendly heating pros are here to help with the best furnace repair in Kankakee, Illinois.

1. Furnace Making a Banging Noise

You may have an urgent problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These range from gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy as time passes, so that’s why it’s important to set seasonal furnace maintenance with Home Furniture, Plumbing & Heating. One of the things our technicians do during this appointment is clean your furnace’s burners. When this part gets grubby, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup might break your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can leak carbon monoxide, which is normally emitted outdoors. This dangerous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Home Furniture, Plumbing & Heating urges you to turn it off and reaching us at 815-933-8213. Too much natural gas in your furnace or a cracked heat exchanger are dangerous issues that necessitate immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide hot air around your house. If the ductwork wasn’t installed properly or is aging, it can be loud when your furnace runs. This can be the issue if your furnace makes a banging noise when it shuts off. Contact Home Furniture, Plumbing & Heating at 815-933-8213 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically means there’s an electrical situation, 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 isn’t tight enough, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes hot or cooled air around your space, and a capacitor, which triggers the motor. If either of these parts are fading, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be related to something small, like a loose screw, or something major, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating specialists at 815-933-8213 for help.

4. Furnace Squeals

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 forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubricated. We know that maintenance often 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 the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent isn’t secure. If you’ve examined your vents but are still hearing sound, Home Furniture, Plumbing & Heating can assist you. It’s essential to get loose ductwork taken care of fast, since it can make comfort problems in your residence and drive up your gas expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound typically means there’s a problem with your furnace’s blower. Switch off your furnace off right away and reach our professionals at 815-933-8213 for support.
