1. Furnace Making a Banging Noise
You might have an urgent issue 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 range from gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over time, so that’s why it’s important to set yearly furnace maintenance with Knoechel Heating. One of the things our technicians do during this appointment is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The resulting gas buildup may break your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can leak carbon monoxide, which is normally released outside. This hazardous gas can be lethal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Knoechel Heating recommends turning it off and reaching us at 724-425-5852. Excessive natural gas in your furnace or a fractured heat exchanger are dangerous problems that should get prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move hot air throughout your home. If the ductwork wasn’t designed correctly or is aging, it can make a lot of noise when your furnace runs. This can be the issue if your furnace makes a banging noise when it shuts off. Contact Knoechel Heating at 724-425-5852 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently means there’s an electrical issue, 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 uses a blower motor, which moves hot or chilly air across your residence, and a capacitor, which triggers the motor. If either of these components are fading, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be due to something little, like a loose screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating pros at 724-425-5852 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to tell you it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubricated. We are aware that maintenance frequently slips your mind, but our techs can get your furnace heating quietly again fast.
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 could also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing whistling, Knoechel Heating can help. It’s essential to get loose ductwork fixed without delay, as it can create comfort issues in your residence and increase your energy bills.
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 sound usually means there’s trouble with your furnace’s blower. Switch off your furnace off now and contact our pros at 724-425-5852 for support.
