When your furnace is running properly, it should deliver warm air without creating too much disruption. While it’s normal to catch your furnace making noise as it starts up, other disruptions are showing your furnace requires immediate professional help.
Here are some of the most common furnace noises and what they can mean. If your furnace is making an odd noise, our friendly heating professionals are here to help with the best furnace repair in New Castle, Pennsylvania.
1. Furnace Making a Banging Noise
You could have a serious problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be several problems. These involve gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over time, so that’s why it’s critical to book yearly furnace maintenance with Central Heating & Plumbing. One of the jobs our technicians perform during this appointment is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can discharge carbon monoxide, which is ordinarily released away from your home. This hazardous gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Central Heating & Plumbing recommends turning it off and calling us at 724-401-1843. Excessive natural gas in your furnace or a fractured heat exchanger are serious troubles that should get fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move heated air across your house. If the ductwork wasn’t designed properly or is getting dated, it can be loud when your furnace is on. This could be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Central Heating & Plumbing at 724-401-1843 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cold air across your rooms, and a capacitor, which starts the motor. If either of these parts are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be due to something small, like an unfastened screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 724-401-1843 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 requires some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing may need to be greased. We realize that maintenance sometimes slips your mind, but our techs can get your furnace operating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also hear whistling while the furnace is on if a floor vent isn’t secure. If you’ve examined your vents but are still sensing whistling, Central Heating & Plumbing can provide support. It’s essential to get loose ductwork fixed fast, since it can result in comfort issues in your residence and drive up your energy 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 sound often means there’s trouble with your furnace’s blower. Switch off your furnace off immediately and contact our pros at 724-401-1843 for support.
