When your furnace is running like it should, it should give heat without creating too much disruption. While it’s common to catch your furnace making noise as it turns on, other sounds are signaling your furnace requires immediate professional support.

Here are some of the most common furnace noises and what they can be indicating. If your furnace is making a weird noise, our friendly heating specialists are here to help with the best furnace repair in Bartlesville, Oklahoma.

1. Furnace Makes a Banging Sound

You could have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These involve gas increasing 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 essential to schedule annual furnace maintenance with Farris Heating & Air. One of the things our techs complete during this work is clean your furnace’s burners. When this piece gets grubby, you could hear your furnace making a loud rumbling noise when ignition takes more time. The subsequent gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any cracks in it can emit carbon monoxide, which is ordinarily emitted outside. This hazardous gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Farris Heating & Air advises turning it off and reaching us at 918-333-0376. Significant natural gas in your furnace or a fractured heat exchanger are critical problems that necessitate immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver warm air across your residence. If the ductwork wasn’t designed right or is getting old, it can make a lot of noise when your furnace is on. This could be the case if your furnace makes a banging noise when it shuts off. Contact Farris Heating & Air at 918-333-0376 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to work on the correct voltage. If wires or the box needs to be tightened, you could hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves warm or cooled air around your space, and a capacitor, which starts the motor. If either of these components are going out, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be related to something minor, like an unsecure screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating professionals 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 on, it’s attempting to tell you it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn down or a bearing may need to be lubricated. We know that maintenance often slips your mind, but our techs can get your furnace running quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You may also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve examined your vents but are still sensing noise, Farris Heating & Air can help. It’s essential to get loose ductwork taken care of quickly, because it can result in comfort issues in your residence and drive up your gas bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal sound typically means there’s trouble with your furnace’s blower. Switch off your furnace off promptly and call us at 918-333-0376 for assistance.
