1. Furnace Making a Banging Noise
You may have a serious problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a few problems. These range from gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy as time passes, so that’s why it’s essential to book seasonal furnace maintenance with Bell Air Conditioning Inc. One of the tasks our technicians complete during this work is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can emit carbon monoxide, which is ordinarily vented away from your home. This dangerous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Bell Air Conditioning Inc urges you to turn it off and contacting us at 254-307-9572. Too much natural gas in your furnace or a cracked heat exchanger are hazardous problems that should get prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move hot air across your house. If the ductwork wasn’t put in right or is aging, it can be loud when your furnace is on. This may be the issue if your furnace makes a banging noise when it shuts off. Contact Bell Air Conditioning Inc at 254-307-9572 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically indicates an electrical problem, 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 may hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or cooled air throughout your house, and a capacitor, which turns on the motor. If either of these pieces are fading, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be the result of something small, like an unfastened screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and calling our heating pros at 254-307-9572 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 needs some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing may need to be lubed. We know that maintenance sometimes slips your mind, but our technicians can get your furnace running quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You may also notice whistling while the furnace is operating if a floor vent isn’t tight. If you’ve examined your vents but are still noticing noise, Bell Air Conditioning Inc can provide support. It’s critical to get loose ductwork taken care of without delay, because it can make comfort troubles in your residence and drive up your heating bills.
6. Furnace Making a Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal racket typically means there’s trouble with your furnace’s blower. Turn off your furnace off right away and call us at 254-307-9572 for support.
