Here are some of the most reported furnace noises and what they could mean. If your furnace is making a strange noise, our friendly heating specialists are here to fix the problem with the best furnace repair in South Beloit and Belvidere, Illinois.
1. Furnace Making a Banging Noise
You might have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be several problems. These range from gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over the years, so that’s why it’s important to schedule seasonal furnace maintenance with Fleming Heating & Air Conditioning Inc. One of the things our pros complete during this work is clean your furnace’s burners. When this component gets dirty, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The resulting gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can leak carbon monoxide, which is regularly vented outdoors. This hazardous gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Fleming Heating & Air Conditioning Inc advises turning it off and contacting us at 877-389-2465. Excessive natural gas in your furnace or a cracked heat exchanger are dangerous issues that require fast service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver heated air throughout your residence. If the ductwork wasn’t installed right or is getting dated, it can be loud when your furnace is on. This could be the case if your furnace makes a banging noise when it shuts off. Call Fleming Heating & Air Conditioning Inc at 877-389-2465 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often means there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the correct voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or cooled air around your house, and a capacitor, which triggers the motor. If either of these parts are failing, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be related to something small, like an unfastened screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating professionals at 877-389-2465 for help.
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 get your attention it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubed. We are aware that maintenance often slips your mind, but our professionals can get your furnace running quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve looked at your vents but are still hearing whistling, Fleming Heating & Air Conditioning Inc can help. It’s essential to get loose ductwork fixed without delay, because it can create comfort problems in your home and increase your utility expenses.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal sound usually means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and reach our pros at 877-389-2465 for help.
