When your furnace is running like it should, it should provide heat without creating too much disruption. While it’s common to catch your furnace making noise as it turns on, other disruptions are indicating your furnace should get immediate professional help.
Here are some of the most common furnace noises and what they might mean. If your furnace is making an odd noise, our friendly heating specialists are here to help with the best furnace repair in Greensburg, Indiana.
1. Furnace Making a Banging Noise
You might have a serious situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be several problems. These involve gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over the years, so that’s why it’s important to set seasonal furnace maintenance with Wallpe Heating & Cooling. One of the things our professionals do during this appointment is clean your furnace’s burners. When this component gets dirty, you may hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup can crack your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can emit carbon monoxide, which is normally released outside. 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 urges you to turn it off and contacting us at 812-663-7252. Too much natural gas in your furnace or a fractured heat exchanger are hazardous issues that require immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move hot air throughout your house. If the ductwork wasn’t installed correctly or is getting old, it can make a lot of noise when your furnace runs. This may be the issue if your furnace makes a banging noise when it shuts off. Get in touch with 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 hesitate to call us. A buzzing sound frequently indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes heated or cold air across your rooms, and a capacitor, which triggers the motor. If either of these parts 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 can be related to something little, like an unfastened screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and contacting 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 running, it’s attempting to get your attention it requires some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn down or a bearing may need to be lubricated. We realize that maintenance sometimes slips your mind, but our professionals can get your furnace heating quietly again quickly.
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 might also be aware of whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still noticing whistling, Wallpe Heating & Cooling can provide support. It’s critical to get loose ductwork fixed without delay, because it can create comfort problems in your home and drive up your gas bills.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal racket typically means there’s an issue with your furnace’s blower. Turn off your furnace off instantly and contact us at 812-663-7252 for assistance.
