When your furnace is running correctly, it should provide heat without generating too much disruption. While it’s common to hear your furnace making noise as it turns on, other disruptions are signaling your furnace requires immediate professional support.

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

1. Furnace Making a Banging Noise

You might have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over the years, so that’s why it’s critical to schedule yearly furnace maintenance with Stephen Hurst Pack Heating and Cooling. One of the things our technicians do during this service is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise after ignition takes more time. The following gas buildup might break your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can discharge carbon monoxide, which is regularly emitted outdoors. This dangerous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Stephen Hurst Pack Heating and Cooling urges you to turn it off and reaching us at 740-474-5940. Excessive natural gas in your furnace or a cracked heat exchanger are serious problems that should get prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide hot air throughout your residence. If the ductwork wasn’t put in right or is aging, it can be loud when your furnace is heating. This could be the issue 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 Buzzes Constantly

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

Your furnace relies on an internal transformer to work on the correct voltage. If wires or the box needs to be tightened, you could detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or chilly air throughout your house, and a capacitor, which starts the motor. If either of these components are going out, they will buzz when the furnace starts.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be the result of something little, like an unfastened screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating professionals at 740-474-5940 for help.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to tell you it requires some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubricated. We know that maintenance frequently slips your mind, but our pros can get your furnace heating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent isn’t secure. If you’ve checked your vents but are still sensing whistling, Stephen Hurst Pack Heating and Cooling can provide support. It’s critical to get loose ductwork fixed without delay, because it can create comfort troubles in your house and inflate your gas costs.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal racket frequently means there’s an issue with your furnace’s blower. Turn off your furnace off instantly and contact our professionals at 740-474-5940 for help.
