When your furnace is running correctly, it should give warmth without creating too much disruption. While it’s common to catch your furnace making noise as it starts up, other sounds are showing your furnace should get immediate professional assistance.
Here are some of the most frequent furnace noises and what they might mean. If your furnace is making an odd noise, our friendly heating professionals are here to help with the best furnace repair in Elk River, Minnesota.
1. Furnace Making a Banging Noise
You might have a critical problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a few problems. These involve gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy as time passes, so that’s why it’s important to book yearly furnace maintenance with Home Comfort Heating & Air. One of the tasks our techs do during this work is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise when ignition takes more time. The resulting gas buildup can crack your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can discharge carbon monoxide, which is regularly released outside. This toxic gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Home Comfort Heating & Air advises turning it off and calling us at 763-276-0617. Significant natural gas in your furnace or a fractured heat exchanger are serious problems that necessitate fast service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver warm air throughout your home. If the ductwork wasn’t put in correctly or is getting old, it can make a lot of noise when your furnace is on. This might be the problem if your furnace makes a banging noise when it shuts off. Contact Home Comfort Heating & Air at 763-276-0617 and we’ll determine 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 usually is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to run on the right voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or chilly air throughout your house, and a capacitor, which triggers the motor. If either of these components are failing, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be related to something small, like an unfastened screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and getting in touch with our heating specialists at 763-276-0617 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it requires some TLC. If you’ve neglected furnace maintenance recently, belts could be worn down or a bearing could need to be greased. We realize that maintenance frequently slips your mind, but our technicians can get your furnace operating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing sound, Home Comfort Heating & Air can assist you. It’s critical to get loose ductwork repaired quickly, as it can create comfort problems in your residence and inflate your heating costs.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal noise usually means there’s a problem with your furnace’s blower. Switch off your furnace off promptly and reach us at 763-276-0617 for help.
