When your furnace is running properly, it should give warmth without generating too much sound. While it’s normal to catch your furnace making noise as it turns on, other disruptions are signaling your furnace requires immediate professional assistance.
Here are some of the most reported furnace noises and what they might mean. If your furnace is making an odd noise, our friendly heating professionals are here to assist with the best furnace repair in Dayton, OH.
1. Furnace Making a Banging Noise
You might have a critical problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be several problems. These involve gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty as time passes, so that’s why it’s essential to set routine furnace maintenance with Jent Mechanical LLC. One of the jobs our pros do during this appointment is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can emit carbon monoxide, which is ordinarily vented away from your home. This hazardous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Jent Mechanical LLC urges you to turn it off and reaching us at 937-845-1111. Excessive natural gas in your furnace or a fractured heat exchanger are critical problems that should get fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver heated air across your residence. If the ductwork wasn’t installed properly or is getting old, it can make a lot of noise when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Call Jent Mechanical LLC at 937-845-1111 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate 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 has a blower motor, which sends hot or cooled air throughout your residence, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it might be the result of something small, like an unfastened screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating pros at 937-845-1111 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to tell you it needs some TLC. If you’ve neglected furnace maintenance recently, belts could be worn down or a bearing might need to be lubed. We realize that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve checked your vents but are still sensing whistling, Jent Mechanical LLC can help. It’s important to get loose ductwork taken care of fast, because it can make comfort problems in your house and drive up your gas bills.
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 racket frequently means there’s an issue with your furnace’s blower. Shut down your furnace off promptly and reach us at 937-845-1111 for assistance.
