When your furnace is running properly, it should provide warm air without creating too much noise. While it’s normal to notice your furnace making noise as it begins running, other sounds are showing your furnace needs immediate professional help.
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 professionals are here to fix the problem with the best furnace repair in South Beloit and Belvidere, IL.
1. Furnace Making a Banging Noise
You could have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a few problems. These involve gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over time, so that’s why it’s critical to set yearly furnace maintenance with Fleming Heating & Air Conditioning Inc. One of the jobs our techs complete during this work is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise after ignition is delayed. The subsequent gas buildup might fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can leak carbon monoxide, which is regularly released away from your home. This toxic gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Fleming Heating & Air Conditioning Inc urges you to turn it off and calling us at 877-389-2465. Excessive natural gas in your furnace or a fractured heat exchanger are dangerous troubles that necessitate prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver heated air across your house. If the ductwork wasn’t put in right or is getting dated, it can be noisy when your furnace is on. This can be the problem if your furnace makes a banging noise when it shuts off. Contact Fleming Heating & Air Conditioning Inc at 877-389-2465 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the right voltage. If wires or the box isn’t tight enough, you may detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves hot or cold air throughout your space, and a capacitor, which starts the motor. If either of these pieces are failing, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be the result of something small, like an unsecure screw, or something critical, like a broken part. In either case, we recommend shutting off your furnace and calling our heating professionals at 877-389-2465 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to tell you it needs some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing might need to be lubed. We are aware that maintenance frequently slips your mind, but our pros can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent is loose. If you’ve checked your vents but are still noticing whistling, Fleming Heating & Air Conditioning Inc can assist you. It’s critical to get loose ductwork fixed without delay, as it can create comfort problems in your house and inflate your gas bills.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound often means there’s an issue with your furnace’s blower. Turn off your furnace off right away and call our pros at 877-389-2465 for assistance.
