When your furnace is operating correctly, it should give warmth without creating too much sound. While it’s normal to notice your furnace making noise as it turns on, other noises are indicating your furnace should get immediate professional assistance.

Here are some of the most frequent furnace noises and what they might mean. If your furnace is making a strange noise, our friendly heating professionals are here to assist with the best furnace repair in Circleville, Ohio.

1. Furnace Making a Banging Noise

You may have a serious problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a couple of problems. These involve gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over time, so that’s why it’s important to set seasonal furnace maintenance with Stephen Hurst Pack Heating and Cooling. One of the jobs our professionals perform during this work is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes more time. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any fractures in it can leak carbon monoxide, which is ordinarily vented outdoors. This toxic gas can be lethal 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 calling us at 740-474-5940. Too much natural gas in your furnace or a cracked heat exchanger are hazardous issues that require prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move warm air across your house. If the ductwork wasn’t put in correctly or is getting old, it can be loud when your furnace runs. This might be the case if your furnace makes a banging noise when it shuts off. Call Stephen Hurst Pack Heating and Cooling at 740-474-5940 and we’ll pinpoint 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 usually indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you might hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or cold air across your home, and a capacitor, which starts the motor. If either of these pieces are failing, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be due to something small, like a loose screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating pros at 740-474-5940 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to get your attention it requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubricated. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace running quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also hear whistling while the furnace is working if a floor vent isn’t tight. If you’ve looked at your vents but are still hearing sound, Stephen Hurst Pack Heating and Cooling can help. It’s critical to get loose ductwork repaired quickly, because it can result in comfort issues in your home and increase your gas bills.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal sound frequently means there’s an issue with your furnace’s blower. Shut down your furnace off instantly and reach us at 740-474-5940 for support.
