Here are some of the most frequent furnace noises and what they might mean. If your furnace is making a weird noise, our friendly heating specialists are here to help with the best furnace repair in Kankakee, Illinois.
1. Furnace Making a Banging Noise
You may have an urgent problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a few problems. These include gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy as time passes, so that’s why it’s critical to book routine furnace maintenance with Home Furniture, Plumbing & Heating. One of the things our technicians perform during this service is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise when ignition is delayed. The resulting gas buildup can break your furnace’s heat exchanger, where natural gas transforms into warmth. Any cracks in it can discharge carbon monoxide, which is normally vented outside. This hazardous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Home Furniture, Plumbing & Heating urges you to turn it off and reaching us at 815-933-8213. Too much natural gas in your furnace or a cracked heat exchanger are serious problems that require prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide warm air throughout your residence. If the ductwork wasn’t installed right or is aging, it can make a lot of noise when your furnace runs. This might be the issue if your furnace makes a banging noise when it shuts off. Contact Home Furniture, Plumbing & Heating at 815-933-8213 and we’ll figure out the problem.
2. Furnace Makes a Buzzing Sound
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the right voltage. If wires or the box is loose, you may detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes warm or chilly air throughout your rooms, and a capacitor, which turns on the motor. If either of these parts are going out, 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 the result of something little, like an unfastened screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and calling our heating professionals at 815-933-8213 for help.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to tell you it could use some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing might need to be lubed. We are aware that maintenance often slips your mind, but our professionals 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 frequently the result of an air leak in your ductwork. You may also notice whistling while the furnace is on if a floor vent isn’t secure. If you’ve examined your vents but are still noticing sound, Home Furniture, Plumbing & Heating can provide support. It’s essential to get loose ductwork taken care of quickly, as it can make comfort issues in your house and drive up your utility costs.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal noise typically means there’s a problem with your furnace’s blower. Switch off your furnace off right away and contact our pros at 815-933-8213 for assistance.
