When your furnace is running properly, it should deliver warm air without generating too much noise. While it’s normal to notice your furnace making noise as it starts up, other disruptions are signaling your furnace requires immediate professional help.
Here are some of the most frequent furnace noises and what they can be signaling. If your furnace is making a strange noise, our friendly heating professionals are here to help with the best furnace repair in Columbus, OH.
1. Furnace Making a Banging Noise
You might have a critical problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a couple of problems. These include gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over time, so that’s why it’s essential to book routine furnace maintenance with Wolfe & Sons Heating and Cooling. One of the things our techs complete during this service is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise when ignition takes more time. The subsequent gas buildup can crack your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can leak carbon monoxide, which is normally emitted outdoors. This hazardous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Wolfe & Sons Heating and Cooling urges you to turn it off and reaching us at 614-451-0846. Excessive natural gas in your furnace or a ruptured heat exchanger are hazardous issues that require immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver hot air around your residence. If the ductwork wasn’t designed properly or is aging, it can be noisy when your furnace runs. This can be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Wolfe & Sons Heating and Cooling at 614-451-0846 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, you may notice 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 space, and a capacitor, which starts the motor. If either of these pieces are failing, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be related to something minor, like a loose screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating professionals at 614-451-0846 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to get your attention it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubed. We are aware that maintenance often slips your mind, but our techs can get your furnace running quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing whistling, Wolfe & Sons Heating and Cooling can provide support. It’s important to get loose ductwork repaired fast, as it can result in comfort problems in your home and inflate your energy bills.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal noise often means there’s trouble with your furnace’s blower. Switch off your furnace off right away and call our pros at 614-451-0846 for help.
