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

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

1. Furnace Makes Banging or Knocking Sounds

You may 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 may indicate there could be a few problems. These include gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy over the years, so that’s why it’s critical to book routine furnace maintenance with Luikart Heating & Cooling. One of the jobs our techs perform during this appointment is clean your furnace’s burners. When this component gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes more time. The resulting gas buildup can crack your furnace’s heat exchanger, where natural gas turns into warmth. Any cracks in it can leak carbon monoxide, which is ordinarily released outdoors. This toxic gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Luikart Heating & Cooling urges you to turn it off and reaching us at 740-344-5497. Significant natural gas in your furnace or a ruptured heat exchanger are hazardous troubles that necessitate fast service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide hot air around your residence. If the ductwork wasn’t put in properly or is aging, it can make a lot of noise when your furnace is heating. This could be the problem 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 determine the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace relies on an internal transformer to work on the right voltage. If wires or the box is loose, you may notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or cold air around your rooms, and a capacitor, which triggers the motor. If either of these components are fading, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be due to something little, like an unfastened screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and calling our heating professionals at 740-344-5497 for help.

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 tell you it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubed. We know that maintenance often slips your mind, but our professionals can get your furnace heating quietly again rapidly.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also be aware of whistling while the furnace is working if a floor vent is loose. If you’ve checked your vents but are still hearing sound, Luikart Heating & Cooling can help. It’s important to get loose ductwork repaired fast, as it can make comfort troubles in your residence and inflate your utility expenses.

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 racket usually means there’s an issue with your furnace’s blower. Switch off your furnace off right away and call our pros at 740-344-5497 for support.
