When your furnace is running like it should, it should give warmth without creating too much sound. While it’s normal to notice your furnace making noise as it starts up, other sounds are signaling your furnace requires immediate professional support.

Here are some of the most common furnace noises and what they can be signaling. If your furnace is making an atypical noise, our friendly heating professionals are here to assist with the best furnace repair in Newark, Ohio.

1. Furnace Making a Banging Noise

You could have a critical issue on your hands if you’re noticing 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 involve gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over the years, so that’s why it’s critical to set seasonal furnace maintenance with Luikart Heating & Cooling. One of the jobs our technicians do during this work is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can discharge carbon monoxide, which is regularly released away from your home. This hazardous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Luikart Heating & Cooling recommends turning it off and contacting us at 740-344-5497. Too much natural gas in your furnace or a cracked heat exchanger are dangerous troubles that necessitate fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver hot air across your residence. If the ductwork wasn’t installed correctly or is getting old, it can be loud when your furnace is heating. This might be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Luikart Heating & Cooling at 740-344-5497 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t hesitate to call 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 run on the right voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or chilly air across your space, and a capacitor, which turns on the motor. If either of these parts are failing, 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 a loose screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating specialists at 740-344-5497 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to alert you it needs some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing might need to be lubricated. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace operating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still noticing noise, Luikart Heating & Cooling can provide support. It’s important to get loose ductwork repaired without delay, since it can create comfort problems in your home and inflate your gas costs.

6. Furnace Making a Grinding Noise

It’s not an encouraging 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. Switch off your furnace off right away and call our professionals at 740-344-5497 for support.
