When your furnace is working properly, it should give warm air without generating too much sound. While it’s normal to hear your furnace making noise as it starts up, other noises are signaling your furnace needs immediate professional help.
Here are some of the most common furnace noises and what they can mean. If your furnace is making an odd noise, our friendly heating specialists are here to assist with the best furnace repair in Grove City, OH.
1. Furnace Making a Banging Noise
You could have an urgent problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a few problems. These include gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over the years, so that’s why it’s critical to schedule routine furnace maintenance with Air Quality Solutions. One of the things our technicians perform during this service is clean your furnace’s burners. When this component gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can discharge carbon monoxide, which is ordinarily emitted outdoors. This hazardous gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Air Quality Solutions urges you to turn it off and contacting us at 614-871-4144. Too much natural gas in your furnace or a ruptured heat exchanger are critical problems that necessitate fast service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide hot air across your house. If the ductwork wasn’t put in correctly or is aging, it can make a lot of noise when your furnace runs. This could be the case if your furnace makes a banging noise when it shuts off. Call Air Quality Solutions at 614-871-4144 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you might notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or chilly air across your house, and a capacitor, which triggers the motor. If either of these parts 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 may be the result of something minor, like an unfastened screw, or something serious, like a broken part. In either case, we recommend shutting off your furnace and calling our heating specialists at 614-871-4144 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to alert you it requires some TLC. If you’ve neglected furnace maintenance recently, belts could be dilapidated or a bearing might need to be lubricated. We are aware that maintenance often slips your mind, but our techs 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 be aware of whistling while the furnace is running if a floor vent isn’t secure. If you’ve looked at your vents but are still hearing whistling, Air Quality Solutions can provide support. It’s important to get loose ductwork taken care of quickly, because it can create comfort troubles in your house and inflate your energy expenses.
6. Furnace Making a Grinding Noise
It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal noise often means there’s an issue with your furnace’s blower. Switch off your furnace off instantly and reach us at 614-871-4144 for help.
