When your furnace is operating like it should, it should provide warmth without creating too much disruption. While it’s expected to hear your furnace making noise as it starts up, other sounds are showing your furnace needs immediate professional help.

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

1. Furnace Makes a Banging Sound

You might have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a few problems. These include gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over time, so that’s why it’s critical to schedule routine furnace maintenance with Luikart Heating & Cooling. One of the jobs our techs complete during this service is clean your furnace’s burners. When this component gets dirty, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The subsequent gas buildup may crack your furnace’s heat exchanger, where natural gas turns into heat. Any cracks in it can leak carbon monoxide, which is normally released outdoors. This toxic gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Luikart Heating & Cooling urges you to turn it off and calling us at 740-344-5497. Too much natural gas in your furnace or a ruptured heat exchanger are serious problems that require fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide hot air across your house. If the ductwork wasn’t installed properly or is getting old, it can be noisy when your furnace runs. This might be the problem if your furnace makes a banging noise when it shuts off. Call Luikart Heating & Cooling at 740-344-5497 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or chilly air around your space, 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 Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be due to something little, like an unfastened screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and calling our heating pros 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 attempting to tell you it requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubed. We realize that maintenance often slips your mind, but our techs can get your furnace operating quietly again rapidly.

5. Furnace Whistles

When you’re noticing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You could also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve examined your vents but are still hearing noise, Luikart Heating & Cooling can provide support. It’s important to get loose ductwork taken care of quickly, because it can make comfort issues in your home and increase your energy costs.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket typically means there’s trouble with your furnace’s blower. Shut down your furnace off now and contact our pros at 740-344-5497 for assistance.
