1. Furnace Making a Banging Noise
You may have an urgent problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a few problems. These involve gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy as time passes, so that’s why it’s important to set yearly furnace maintenance with Wallpe Heating & Cooling. One of the tasks our techs perform during this work is clean your furnace’s burners. When this part gets dirty, you could hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can discharge carbon monoxide, which is regularly vented away from your home. This dangerous gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Wallpe Heating & Cooling recommends turning it off and contacting us at 812-663-7252. Excessive natural gas in your furnace or a fractured heat exchanger are hazardous troubles that should get prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move hot air across your residence. If the ductwork wasn’t installed right or is getting dated, it can be noisy when your furnace runs. This could be the case if your furnace makes a banging noise when it shuts off. Call Wallpe Heating & Cooling at 812-663-7252 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically means there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the proper 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 uses a blower motor, which distributes 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 could be the result of something little, like an unfastened screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and calling our heating specialists at 812-663-7252 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to get your attention it could use some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubricated. We realize that maintenance often slips your mind, but our pros can get your furnace operating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You might also be aware of whistling while the furnace is running if a floor vent isn’t tight. If you’ve examined your vents but are still noticing whistling, Wallpe Heating & Cooling can assist you. It’s critical to get loose ductwork repaired quickly, since it can create comfort issues in your residence and drive up your gas costs.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal noise usually means there’s a problem with your furnace’s blower. Turn off your furnace off immediately and call our pros at 812-663-7252 for assistance.
