Here are some of the most common furnace noises and what they can mean. If your furnace is making a strange noise, our friendly heating professionals are here to assist with the best furnace repair in Moline, IL.
1. Furnace Making a Banging Noise
You could have a serious problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a few problems. These range from gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy over time, so that’s why it’s essential to set routine furnace maintenance with Freed Heating & Air Conditioning. One of the tasks our professionals do during this appointment is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise when ignition takes more time. The resulting gas buildup might crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any cracks in it can discharge carbon monoxide, which is ordinarily emitted away from your home. This toxic gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Freed Heating & Air Conditioning recommends turning it off and reaching us at 309-323-9584. Too much natural gas in your furnace or a ruptured heat exchanger are critical troubles that require fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move heated air throughout your house. If the ductwork wasn’t installed right or is aging, it can make a lot of noise when your furnace is heating. This could be the case if your furnace makes a banging noise when it shuts off. Contact Freed Heating & Air Conditioning at 309-323-9584 and we’ll figure out 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 typically is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the proper voltage. If wires or the box needs to be tightened, you may hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends warm or cold air around your rooms, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it might be due to something small, like a loose screw, or something major, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating pros 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 going, it’s attempting to alert you it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be dilapidated or a bearing could need to be greased. We know that maintenance often slips your mind, but our techs can get your furnace running quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You could also hear whistling while the furnace is on if a floor vent is loose. If you’ve looked at your vents but are still sensing whistling, Freed Heating & Air Conditioning can help. It’s essential to get loose ductwork taken care of without delay, because it can make comfort issues in your home and increase your energy 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 usually means there’s an issue with your furnace’s blower. Shut down your furnace off instantly and contact our professionals at 309-323-9584 for assistance.
