When your furnace is working correctly, it should give heat without generating too much disruption. While it’s expected to hear your furnace making noise as it begins running, other disruptions are showing your furnace needs immediate professional help.

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

1. Furnace Making a Banging Noise

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 indicate there could be a few problems. These involve gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over time, so that’s why it’s critical to set yearly furnace maintenance with Luikart Heating & Cooling. One of the tasks our pros perform during this appointment is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup might break your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can emit 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 advises turning it off and calling us at 740-200-5591. Too much natural gas in your furnace or a fractured heat exchanger are hazardous troubles that necessitate prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move warm air throughout your residence. If the ductwork wasn’t designed correctly or is getting dated, it can be noisy when your furnace is on. This may be the issue if your furnace makes a banging noise when it shuts off. Contact Luikart Heating & Cooling at 740-200-5591 and we’ll determine 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 often indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to operate on the proper voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves heated or cooled air around your space, and a capacitor, which starts the motor. If either of these parts are going out, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be the result of something little, like a loose screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating professionals at 740-200-5591 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to alert you it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be lubed. We know that maintenance often slips your mind, but our techs can get your furnace operating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also be aware of whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still hearing whistling, Luikart Heating & Cooling can help. It’s essential to get loose ductwork repaired fast, because it can result in comfort problems in your house and increase your heating expenses.

6. Furnace Making a Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket usually means there’s an issue with your furnace’s blower. Turn off your furnace off promptly and call our professionals at 740-200-5591 for help.

When you’re noticing an atypical noise from your furnace, Luikart Heating & Cooling is here to provide assistance. Contact us at 740-200-5591 to schedule your furnace repair appointment right away.
