When your furnace is working properly, it should give heat without making too much sound. While it’s normal to hear your furnace making noise as it starts up, other disruptions are signaling your furnace requires immediate professional support.
Here are some of the most common furnace noises and what they might mean. If your furnace is making a strange noise, our friendly heating pros are here to assist with the best furnace repair in Genoa, Illinois.
1. Furnace Making a Banging Noise
You could have a serious issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a few problems. These involve gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over the years, so that’s why it’s essential to book seasonal furnace maintenance with Assured Appliance & Heating & Air. One of the things our professionals perform during this appointment is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can emit carbon monoxide, which is ordinarily released away from your home. This hazardous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Assured Appliance & Heating & Air urges you to turn it off and contacting us at 847-306-8990. Too much natural gas in your furnace or a cracked heat exchanger are hazardous issues that necessitate fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move hot air throughout your house. If the ductwork wasn’t put in correctly or is getting old, 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 Assured Appliance & Heating & Air at 847-306-8990 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to run on the correct voltage. If wires or the box is loose, you might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or chilly air throughout your home, and a capacitor, which starts the motor. If either of these parts are fading, 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 little, like a loose screw, or something serious, like a broken part. In either case, we advise shutting your furnace off and contacting our heating specialists at 847-306-8990 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to tell you it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubricated. We realize that maintenance often slips your mind, but our pros 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 typically the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is working if a floor vent is loose. If you’ve looked at your vents but are still noticing whistling, Assured Appliance & Heating & Air can provide support. It’s important to get loose ductwork fixed quickly, because it can create comfort problems in your residence and drive up your utility expenses.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal noise often means there’s an issue with your furnace’s blower. Shut down your furnace off instantly and contact our professionals at 847-306-8990 for assistance.
