When your furnace is working like it should, it should deliver warmth without making too much sound. While it’s common to catch your furnace making noise as it starts up, other noises are indicating your furnace needs immediate professional assistance.
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 Menomonie and western Wisconsin, Wisconsin.
1. Furnace Making a Banging Noise
You might have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These include gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over time, so that’s why it’s critical to set yearly furnace maintenance with Halverson Brothers Inc. One of the tasks our techs complete during this service is clean your furnace’s burners. When this piece gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into heat. Any fractures in it can emit carbon monoxide, which is ordinarily emitted away from your home. This dangerous gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Halverson Brothers Inc urges you to turn it off and calling us at 715-352-4052. Excessive natural gas in your furnace or a ruptured heat exchanger are dangerous troubles that necessitate fast service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move hot air throughout your home. If the ductwork wasn’t put in properly or is aging, it can be loud when your furnace runs. This might be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Halverson Brothers Inc at 715-352-4052 and we’ll determine 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 indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the correct 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 has a blower motor, which distributes hot or cooled air throughout your rooms, and a capacitor, which turns on the motor. If either of these pieces are going out, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be related to something minor, like an unsecure screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 715-352-4052 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to alert you it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubed. We are aware that maintenance frequently slips your mind, but our pros can get your furnace heating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still noticing whistling, Halverson Brothers Inc can help. It’s critical to get loose ductwork taken care of quickly, because it can create comfort issues in your residence and increase your heating costs.
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 noise often means there’s a problem with your furnace’s blower. Shut down your furnace off promptly and contact our professionals at 715-352-4052 for support.
