1. Furnace Making a Banging Noise
You could have a critical problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be several problems. These range from gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy as time passes, so that’s why it’s critical to book seasonal furnace maintenance with H & H Service Company. One of the tasks our technicians perform during this work is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup might break your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can leak carbon monoxide, which is regularly released 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, H & H Service Company urges you to turn it off and reaching us at 717-220-4502. Too much natural gas in your furnace or a broken heat exchanger are critical issues that should get immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide heated air throughout your home. If the ductwork wasn’t installed correctly or is aging, it can be loud when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Contact H & H Service Company at 717-220-4502 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the right voltage. If wires or the box is loose, you might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or chilly air throughout your space, and a capacitor, which starts 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 can be due to something small, like an unfastened screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating professionals at 717-220-4502 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 get your attention it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing might need to be greased. We realize that maintenance often slips your mind, but our technicians can get your furnace running quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also notice whistling while the furnace is working if a floor vent isn’t secure. If you’ve looked at your vents but are still sensing noise, H & H Service Company can help. It’s important to get loose ductwork fixed fast, as it can result in comfort issues in your home and increase your heating costs.
6. Furnace Making a Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise usually means there’s an issue with your furnace’s blower. Shut down your furnace off promptly and contact us at 717-220-4502 for assistance.
