When your furnace is operating properly, it should deliver warmth without making too much noise. While it’s common to catch your furnace making noise as it turns on, other disruptions are showing your furnace needs immediate professional assistance.
Here are some of the most common furnace noises and what they could be signaling. If your furnace is making an odd noise, our friendly heating pros are here to assist with the best furnace repair in West Jefferson, Ohio.
1. Furnace Makes Banging or Knocking Sounds
You might have a critical issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean 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 becomes dirty as time passes, so that’s why it’s critical to set seasonal furnace maintenance with West Jefferson Plumbing and Heating, Inc.. One of the tasks our techs complete during this appointment is clean your furnace’s burners. When this part gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes more time. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can emit carbon monoxide, which is normally released away from your home. This hazardous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, West Jefferson Plumbing and Heating, Inc. advises turning it off and contacting us at 614-879-9091. Too much natural gas in your furnace or a broken heat exchanger are dangerous problems that should get prompt attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to provide warm air around your home. If the ductwork wasn’t put in right or is getting old, it can be loud when your furnace runs. This may be the issue if your furnace makes a banging noise when it shuts off. Call West Jefferson Plumbing and Heating, Inc. at 614-879-9091 and we’ll pinpoint the problem.
2. Furnace Buzzes Constantly
If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the right 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 uses a blower motor, which sends hot or cold air across your house, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace turns on.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it can be due to something small, like a loose screw, or something serious, like a broken component. In either case, we advise shutting your furnace off and calling our heating pros at 614-879-9091 for support.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting 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 lubricated. We know that maintenance frequently slips your mind, but our pros can get your furnace running quietly again fast.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also be aware of whistling while the furnace is running if a floor vent isn’t tight. If you’ve examined your vents but are still noticing whistling, West Jefferson Plumbing and Heating, Inc. can provide support. It’s essential to get loose ductwork taken care of without delay, as it can result in comfort problems in your residence and drive up your gas bills.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise usually means there’s a problem with your furnace’s blower. Turn off your furnace off right away and call our pros at 614-879-9091 for support.
