When your furnace is operating like it should, it should give heat without making too much noise. While it’s normal to hear your furnace making noise as it turns on, other disruptions are signaling your furnace needs immediate professional support.

Here are some of the most reported furnace noises and what they might mean. If your furnace is making an atypical noise, our friendly heating pros are here to help with the best furnace repair in Bartlesville, Oklahoma.

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 can mean there could be a couple of problems. These range from gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over time, so that’s why it’s critical to set seasonal furnace maintenance with Farris Heating & Air. One of the tasks our pros perform during this service is clean your furnace’s burners. When this component gets dirty, you could hear your furnace making a loud rumbling noise if ignition takes more time. The resulting 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 ordinarily released outdoors. This hazardous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Farris Heating & Air recommends turning it off and contacting us at 918-333-0376. Significant natural gas in your furnace or a broken heat exchanger are serious problems that necessitate immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver warm air around your residence. If the ductwork wasn’t designed properly or is getting dated, it can be noisy when your furnace is heating. This may be the issue if your furnace makes a banging noise when it shuts off. Call Farris Heating & Air at 918-333-0376 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently means there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or cooled air across your rooms, and a capacitor, which turns on the motor. If either of these pieces 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 can be due to something little, like a loose screw, or something major, like a broken piece. In either case, we advise shutting your furnace off and calling our heating specialists at 918-333-0376 for help.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to alert you it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing could need to be greased. We know that maintenance often slips your mind, but our professionals can get your furnace operating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve looked at your vents but are still hearing sound, Farris Heating & Air can help. It’s important to get loose ductwork taken care of quickly, because it can result in comfort troubles in your house and increase your utility bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal racket typically means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and reach our professionals at 918-333-0376 for assistance.
