When your furnace is running properly, it should provide warmth without creating too much disruption. While it’s normal to notice your furnace making noise as it begins running, other sounds are showing your furnace should get immediate professional assistance.
Here are some of the most reported furnace noises and what they could mean. If your furnace is making a weird noise, our friendly heating pros are here to assist with the best furnace repair in Kutztown, PA.
1. Furnace Making a Banging Noise
You may have an urgent 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 a couple of problems. These include gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over time, so that’s why it’s important to book yearly furnace maintenance with Moyer Total Indoor Comfort. One of the tasks our professionals perform during this work is clean your furnace’s burners. When this component gets dirty, you could hear your furnace making a loud rumbling noise when ignition takes longer than normal. The resulting gas buildup might crack your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can emit carbon monoxide, which is regularly released away from your home. This toxic gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Moyer Total Indoor Comfort urges you to turn it off and calling us at 484-646-3363. Excessive natural gas in your furnace or a fractured heat exchanger are serious troubles that require fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver heated air around your residence. If the ductwork wasn’t installed properly or is aging, it can be loud when your furnace runs. This might be the issue if your furnace makes a banging noise when it shuts off. Contact Moyer Total Indoor Comfort at 484-646-3363 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you may hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or chilly air around your house, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be due to something minor, like a loose screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating professionals at 484-646-3363 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to alert you it needs some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn down or a bearing might need to be greased. We are aware that maintenance frequently slips your mind, but our pros can get your furnace heating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve looked at your vents but are still hearing whistling, Moyer Total Indoor Comfort can assist you. It’s critical to get loose ductwork fixed quickly, because it can result in comfort issues in your home and drive up your energy expenses.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal racket often means there’s an issue with your furnace’s blower. Shut down your furnace off promptly and contact us at 484-646-3363 for support.
