When your furnace is operating like it should, it should give warm air without generating too much sound. While it’s common to catch your furnace making noise as it starts up, other sounds are signaling your furnace should get immediate professional support.

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

1. Furnace Making a Banging Noise

You might have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a couple of problems. These range from gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over time, so that’s why it’s essential to set annual furnace maintenance with Comfort Concepts Heating & Air Conditioning. One of the jobs our pros complete during this service is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise after ignition takes more time. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can emit carbon monoxide, which is normally emitted outdoors. This hazardous gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Comfort Concepts Heating & Air Conditioning urges you to turn it off and calling us at 405-494-7444. Excessive natural gas in your furnace or a ruptured heat exchanger are dangerous problems that should get fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide warm air throughout your home. If the ductwork wasn’t installed correctly or is aging, it can be noisy when your furnace is heating. This can be the problem if your furnace makes a banging noise when it shuts off. Call Comfort Concepts Heating & Air Conditioning at 405-494-7444 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the right voltage. If wires or the box needs to be tightened, you may notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or cooled air across your space, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it could be due to something little, like an unsecure screw, or something critical, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 405-494-7444 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to tell you it needs some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubricated. We are aware that maintenance sometimes slips your mind, but our pros can get your furnace operating quietly again quickly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent isn’t secure. If you’ve checked your vents but are still hearing sound, Comfort Concepts Heating & Air Conditioning can provide support. It’s critical to get loose ductwork fixed quickly, because it can make comfort troubles in your residence and increase your energy bills.

6. Furnace Making a Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise frequently means there’s trouble with your furnace’s blower. Switch off your furnace off now and call us at 405-494-7444 for assistance.
