When your furnace is operating like it should, it should give warmth without generating too much disruption. While it’s common to catch your furnace making noise as it starts up, other disruptions are indicating your furnace should get immediate professional assistance.

Here are some of the most reported furnace noises and what they might mean. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Newark, Ohio.

1. Furnace Makes a Banging Sound

You might have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a couple of problems. These include gas building up in your furnace or a ductwork issue.

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 things our techs perform during this work is clean your furnace’s burners. When this piece gets grimy, you may hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any cracks in it can leak carbon monoxide, which is normally vented outside. This hazardous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Luikart Heating & Cooling advises turning it off and calling us at 740-344-5497. Too much natural gas in your furnace or a broken heat exchanger are critical troubles that necessitate fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide heated air throughout your home. If the ductwork wasn’t designed properly or is getting old, it can make a lot of noise when your furnace is on. This may be the case if your furnace makes a banging noise when it shuts off. Contact 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 delay calling us. A buzzing sound usually indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to run on the correct 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 works with a blower motor, which distributes heated or chilly air across your rooms, and a capacitor, which starts the motor. If either of these components are going out, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be related to something minor, like an unsecure 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 help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to alert you it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubed. We are aware that maintenance sometimes slips your mind, but our technicians can get your furnace heating quietly again rapidly.

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 might also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing sound, Luikart Heating & Cooling can provide support. It’s essential to get loose ductwork repaired without delay, since it can make comfort problems in your residence and inflate your utility bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal noise often means there’s a problem with your furnace’s blower. Turn off your furnace off right away and reach our pros at 740-344-5497 for assistance.
