When your furnace is working correctly, it should give warm air without making too much disruption. While it’s expected to hear your furnace making noise as it turns on, other disruptions are showing your furnace requires immediate professional help.
Here are some of the most common furnace noises and what they could be signaling. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Bloomfield, Indiana.
1. Furnace Making a Banging Noise
You could have a serious issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a few problems. These range from gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy as time passes, so that’s why it’s essential to book yearly furnace maintenance with Stanford Heating & Cooling. One of the jobs our pros do during this appointment is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into warmth. Any fractures in it can emit carbon monoxide, which is regularly released outdoors. This hazardous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Stanford Heating & Cooling advises turning it off and reaching us at 812-825-8695. Too much natural gas in your furnace or a fractured heat exchanger are dangerous issues that should get prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move hot air across your home. If the ductwork wasn’t put in correctly or is aging, it can be loud when your furnace is heating. This can be the problem if your furnace makes a banging noise when it shuts off. Contact Stanford Heating & Cooling at 812-825-8695 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often means there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to work on the correct voltage. If wires or the box needs to be tightened, you may hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes warm or chilly air throughout your rooms, and a capacitor, which triggers the motor. If either of these components 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 could be the result of something little, like an unsecure screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating pros at 812-825-8695 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to alert you it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing may need to be lubed. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace operating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You may also hear whistling while the furnace is running if a floor vent is loose. If you’ve examined your vents but are still noticing noise, Stanford Heating & Cooling can help. It’s essential to get loose ductwork repaired without delay, because it can result in comfort troubles in your house and drive up your heating bills.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal sound often means there’s trouble with your furnace’s blower. Turn off your furnace off promptly and contact our professionals at 812-825-8695 for help.
