When your furnace is running like it should, it should give heat without making too much disruption. While it’s common to catch your furnace making noise as it turns on, other disruptions are showing your furnace should get immediate professional support.
Here are some of the most common furnace noises and what they might be indicating. If your furnace is making an atypical noise, our friendly heating pros are here to assist with the best furnace repair in Wisconsin Rapids, WI.
1. Furnace Making a Banging Noise
You might have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a few problems. These involve gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over the years, so that’s why it’s critical to book routine furnace maintenance with Rapids Sheet Metal Works Inc. One of the jobs our professionals perform during this appointment is clean your furnace’s burners. When this component gets grubby, you might hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can leak carbon monoxide, which is regularly released away from your home. This toxic gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Rapids Sheet Metal Works Inc recommends turning it off and contacting us at 715-301-0256. Significant natural gas in your furnace or a fractured heat exchanger are dangerous troubles that should get prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver warm air throughout your house. If the ductwork wasn’t installed correctly or is aging, it can be noisy when your furnace is on. This may be the issue if your furnace makes a banging noise when it shuts off. Contact Rapids Sheet Metal Works Inc at 715-301-0256 and we’ll pinpoint 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 situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the correct voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or cooled air across your space, and a capacitor, which turns on the motor. If either of these pieces are going out, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be related to something minor, like an unfastened screw, or something major, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 715-301-0256 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to tell you it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be dilapidated or a bearing may need to be lubricated. We are aware that maintenance sometimes slips your mind, but our techs can get your furnace operating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also be aware of whistling while the furnace is running if a floor vent isn’t secure. If you’ve checked your vents but are still noticing whistling, Rapids Sheet Metal Works Inc can help. It’s essential to get loose ductwork repaired without delay, as it can result in comfort issues in your home and drive up your gas expenses.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise often means there’s an issue with your furnace’s blower. Shut down your furnace off instantly and reach us at 715-301-0256 for assistance.
