When your furnace is working properly, it should give warm air without making too much sound. While it’s common to hear your furnace making noise as it turns on, other disruptions are showing your furnace should get immediate professional support.

Here are some of the most frequent furnace noises and what they can be indicating. If your furnace is making a weird noise, our friendly heating pros are here to fix the problem with the best furnace repair in Genoa, Illinois.

1. Furnace Making a Banging Noise

You could have a critical problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These involve gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over time, so that’s why it’s important to set annual furnace maintenance with Assured Appliance & Heating & Air. One of the things our professionals do during this work is clean your furnace’s burners. When this part gets grubby, you may hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup might break your furnace’s heat exchanger, where natural gas turns into heat. Any breaks in it can emit carbon monoxide, which is regularly released outdoors. This hazardous gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Assured Appliance & Heating & Air recommends turning it off and reaching us at +1 847-293-0047. Too much natural gas in your furnace or a broken heat exchanger are critical problems that require fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide hot air around your residence. If the ductwork wasn’t designed 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. Call Assured Appliance & Heating & Air at +1 847-293-0047 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t hesitate 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 operate on the proper voltage. If wires or the box needs to be tightened, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves warm or cooled air throughout your rooms, and a capacitor, which triggers the motor. If either of these components are going out, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be related to something minor, like a loose screw, or something major, like a broken part. In either case, we urge you to shut your furnace off and calling our heating pros at +1 847-293-0047 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubed. We are aware that maintenance often slips your mind, but our techs can get your furnace heating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent isn’t secure. If you’ve checked your vents but are still hearing whistling, Assured Appliance & Heating & Air 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 increase your gas costs.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal racket typically means there’s an issue with your furnace’s blower. Shut down your furnace off right away and call our professionals at +1 847-293-0047 for support.
