When your furnace is operating properly, it should give heat without generating too much sound. While it’s expected to notice your furnace making noise as it begins running, other sounds are showing your furnace should get immediate professional assistance.

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

1. Furnace Makes a Banging Sound

You may have a serious issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be several problems. These range from gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over time, so that’s why it’s important to book yearly furnace maintenance with Stephen Hurst Pack Heating and Cooling. One of the things our pros perform 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 is delayed. The ensuing gas buildup may break your furnace’s heat exchanger, where natural gas turns into warmth. Any cracks in it can discharge carbon monoxide, which is ordinarily vented outside. This dangerous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Stephen Hurst Pack Heating and Cooling advises turning it off and contacting us at 740-474-5940. Excessive natural gas in your furnace or a fractured heat exchanger are dangerous troubles that require immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver heated air across your house. If the ductwork wasn’t put in correctly or is getting dated, it can make a lot of noise when your furnace runs. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Stephen Hurst Pack Heating and Cooling at 740-474-5940 and we’ll pinpoint the problem.

2. Furnace Makes a Buzzing Sound

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you might detect 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 triggers the motor. If either of these pieces are fading, they will buzz when the furnace switches on.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be the result of something little, like an unfastened screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating pros at 740-474-5940 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to alert you it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubed. We know that maintenance often slips your mind, but our pros can get your furnace operating quietly again quickly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You might also notice whistling while the furnace is on if a floor vent isn’t secure. If you’ve examined your vents but are still hearing sound, Stephen Hurst Pack Heating and Cooling can help. It’s critical to get loose ductwork repaired without delay, as it can make comfort problems in your home and increase your energy costs.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal racket typically means there’s a problem with your furnace’s blower. Shut down your furnace off promptly and contact our pros at 740-474-5940 for help.
