Here are some of the most frequent furnace noises and what they could mean. If your furnace is making an odd noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Moline, Illinois.
1. Furnace Making a Banging Noise
You might have an urgent issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate 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 dirty as time passes, so that’s why it’s important to schedule yearly furnace maintenance with Freed Heating & Air Conditioning. One of the jobs our techs complete during this work is clean your furnace’s burners. When this part gets grimy, you might hear your furnace making a loud rumbling noise after ignition is delayed. The subsequent gas buildup might break your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can discharge carbon monoxide, which is regularly vented outdoors. This toxic gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Freed Heating & Air Conditioning urges you to turn it off and calling us at 309-323-9584. Excessive natural gas in your furnace or a fractured heat exchanger are hazardous issues that should get prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move warm air around your home. If the ductwork wasn’t designed right or is getting old, it can be noisy when your furnace runs. This could be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Freed Heating & Air Conditioning at 309-323-9584 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the proper voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves warm or chilly air around your residence, and a capacitor, which turns on the motor. If either of these pieces 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 could be the result of something small, like an unsecure screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 309-323-9584 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to get your attention it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing may need to be greased. We realize that maintenance frequently slips your mind, but our technicians can get your furnace operating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You could also notice whistling while the furnace is working if a floor vent is loose. If you’ve checked your vents but are still noticing noise, Freed Heating & Air Conditioning can help. It’s critical to get loose ductwork repaired fast, because it can result in comfort troubles in your house 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 typically means there’s a problem with your furnace’s blower. Turn off your furnace off promptly and contact us at 309-323-9584 for assistance.
