When your furnace is working correctly, it should give warmth without generating too much noise. While it’s common to catch your furnace making noise as it starts up, other noises are showing your furnace requires immediate professional assistance.

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

1. Furnace Making a Banging Noise

You could have an urgent issue 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 couple of problems. These range from gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over time, so that’s why it’s important to schedule routine furnace maintenance with Stephen Hurst Pack Heating and Cooling. One of the jobs our professionals do during this service is clean your furnace’s burners. When this component gets dirty, you may hear your furnace making a loud rumbling noise after ignition is delayed. The resulting gas buildup might break your furnace’s heat exchanger, where natural gas turns into heat. Any fractures in it can leak carbon monoxide, which is regularly vented away from your home. This hazardous gas can be lethal in large concentrations.

If you’re aware of 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. Significant natural gas in your furnace or a cracked heat exchanger are hazardous troubles that require fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move heated air across your house. If the ductwork wasn’t installed correctly or is getting old, it can make a lot of noise when your furnace is heating. This may be the case 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 determine the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to run on the proper voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes hot or chilly air around your home, and a capacitor, which starts the motor. If either of these components 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 can be related to something small, like an unsecure screw, or something major, like a broken component. In either case, we advise shutting your furnace off and contacting our heating specialists at 740-474-5940 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to get your attention it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubricated. We are aware that maintenance sometimes slips your mind, but our pros can get your furnace operating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You could also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve examined your vents but are still sensing whistling, Stephen Hurst Pack Heating and Cooling can assist you. It’s important to get loose ductwork fixed without delay, as it can create comfort issues in your house and drive up your utility expenses.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound often means there’s an issue with your furnace’s blower. Turn off your furnace off right away and reach us at 740-474-5940 for assistance.
