When your furnace is working correctly, it should deliver warm air without making too much sound. While it’s expected to notice your furnace making noise as it starts up, other sounds are indicating your furnace needs immediate professional assistance.
Here are some of the most frequent furnace noises and what they might be signaling. If your furnace is making an odd noise, our friendly heating pros are here to assist with the best furnace repair in Tannersville, Pennsylvania.
1. Furnace Making a Banging Noise
You might have an urgent problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a few problems. These range from gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over time, so that’s why it’s critical to book seasonal furnace maintenance with Speed Air. One of the tasks our professionals perform during this service is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise after ignition takes more time. The following gas buildup can crack your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can discharge carbon monoxide, which is regularly emitted outside. This dangerous gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Speed Air urges you to turn it off and calling us at 800-941-0247. Too much natural gas in your furnace or a fractured heat exchanger are serious troubles that necessitate prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide warm air across your home. If the ductwork wasn’t designed right or is getting old, it can be loud when your furnace runs. This might be the issue if your furnace makes a banging noise when it shuts off. Contact Speed Air at 800-941-0247 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you may notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves warm or cold air around your rooms, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be related to something little, like a loose screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating specialists at 800-941-0247 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to tell you it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubed. We know that maintenance sometimes slips your mind, but our pros can get your furnace heating quietly again quickly.
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 may also be aware of whistling while the furnace is running if a floor vent is loose. If you’ve checked your vents but are still noticing noise, Speed Air can help. It’s critical to get loose ductwork repaired quickly, because it can result in comfort problems in your house and inflate your gas bills.
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. Switch off your furnace off immediately and reach our professionals at 800-941-0247 for support.
