1. Furnace Making a Banging Noise
You might 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 may signal there could be a couple of problems. These involve gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy as time passes, so that’s why it’s critical to set seasonal furnace maintenance with Lanz Furnace and Fireplace. One of the jobs our professionals do during this service is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise after ignition takes longer than normal. The following gas buildup may break your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can discharge carbon monoxide, which is ordinarily emitted outdoors. This dangerous gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Lanz Furnace and Fireplace advises turning it off and reaching us at 608-291-3606. Excessive natural gas in your furnace or a fractured heat exchanger are serious problems that should get immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move warm air throughout your residence. If the ductwork wasn’t installed correctly or is aging, it can make a lot of noise when your furnace is heating. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Lanz Furnace and Fireplace at 608-291-3606 and we’ll pinpoint the problem.
2. Furnace Makes a Buzzing Sound
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently indicates 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 might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves heated or chilly air across your rooms, and a capacitor, which triggers the motor. If either of these pieces are fading, 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 minor, like an unsecure screw, or something major, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating pros at 608-291-3606 for help.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to get your attention it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubricated. We realize that maintenance sometimes slips your mind, but our techs can get your furnace running quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent is loose. If you’ve examined your vents but are still noticing whistling, Lanz Furnace and Fireplace can assist you. It’s essential to get loose ductwork fixed without delay, since it can create comfort problems in your home and drive up your gas expenses.

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal sound frequently means there’s an issue with your furnace’s blower. Turn off your furnace off instantly and contact our professionals at 608-291-3606 for help.
