Here are some of the most frequent 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 Jefferson City, Missouri.
1. Furnace Making a Banging Noise
You may have a critical issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a couple of problems. These involve gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy as time passes, so that’s why it’s critical to book routine furnace maintenance with Stieferman Heating Company Inc. One of the things our professionals perform during this work is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise after ignition takes more time. The resulting gas buildup might crack your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can leak carbon monoxide, which is regularly vented outdoors. This hazardous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Stieferman Heating Company Inc urges you to turn it off and reaching us at 573-635-3547. Too much natural gas in your furnace or a cracked heat exchanger are critical troubles that necessitate prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move heated air throughout your home. If the ductwork wasn’t put in properly or is getting dated, it can make a lot of noise when your furnace runs. This could be the case if your furnace makes a banging noise when it shuts off. Get in touch with Stieferman Heating Company Inc at 573-635-3547 and we’ll determine 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 frequently indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the right voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or chilly air across your house, and a capacitor, which starts the motor. If either of these components are failing, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be due to something small, like an unfastened screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating specialists at 573-635-3547 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to tell you it needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing could 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 because of an air leak in your ductwork. You might also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still hearing sound, Stieferman Heating Company Inc can assist you. It’s essential to get loose ductwork taken care of fast, since it can result in comfort troubles in your residence and drive up your energy costs.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal noise typically means there’s trouble with your furnace’s blower. Turn off your furnace off promptly and contact our professionals at 573-635-3547 for help.
