When your furnace is working properly, it should provide warmth without making too much sound. While it’s common to notice your furnace making noise as it starts up, other disruptions are showing your furnace needs immediate professional support.
Here are some of the most frequent furnace noises and what they might 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 Franklin Lakes, NJ.
1. Furnace Making a Banging Noise
You could have a critical issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a couple of problems. These include gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over time, so that’s why it’s important to book seasonal furnace maintenance with Total Comfort. One of the jobs our techs perform during this work is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise after ignition is delayed. The resulting gas buildup may break your furnace’s heat exchanger, where natural gas turns into heat. Any breaks in it can discharge carbon monoxide, which is ordinarily released 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, Total Comfort advises turning it off and reaching us at 201-268-5663. Too much natural gas in your furnace or a fractured heat exchanger are critical issues that require fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide heated air throughout your residence. If the ductwork wasn’t installed correctly or is getting dated, it can make a lot of noise when your furnace is heating. This can be the case if your furnace makes a banging noise when it shuts off. Get in touch with Total Comfort at 201-268-5663 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 indicates an electrical issue, 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 notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or cooled air around your residence, and a capacitor, which triggers the motor. If either of these parts 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 might be due to something little, like an unfastened screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and calling our heating pros at 201-268-5663 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to alert you it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubed. We know that maintenance frequently slips your mind, but our techs can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically due to 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 examined your vents but are still hearing whistling, Total Comfort can provide support. It’s important to get loose ductwork fixed without delay, as it can make comfort troubles in your home and drive up your heating bills.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal sound often means there’s an issue with your furnace’s blower. Switch off your furnace off promptly and call us at 201-268-5663 for support.
