1. Furnace Making a Banging Noise

You may have an urgent issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate 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 becomes filthy over the years, so that’s why it’s essential to book seasonal furnace maintenance with Van Haaften Plumbing & Heating. One of the jobs our technicians complete 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 resulting gas buildup may break your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can leak carbon monoxide, which is regularly emitted away from your home. This hazardous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Van Haaften Plumbing & Heating advises turning it off and reaching us at 641-628-3621. Significant natural gas in your furnace or a cracked heat exchanger are dangerous issues that should get immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide warm air throughout your residence. If the ductwork wasn’t installed correctly or is aging, it can make a lot of noise when your furnace is heating. This can be the issue if your furnace makes a banging noise when it shuts off. Contact Van Haaften Plumbing & Heating at 641-628-3621 and we’ll figure out 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 frequently indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to operate on the proper voltage. If wires or the box isn’t tight enough, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes warm or chilly air across your rooms, and a capacitor, which starts the motor. If either of these pieces are failing, 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 minor, like an unsecure screw, or something major, like a broken part. In either case, we advise shutting your furnace off and contacting our heating professionals at 641-628-3621 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to get your attention it requires some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing may need to be greased. We realize that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again fast.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You might also notice whistling while the furnace is operating if a floor vent is loose. If you’ve looked at your vents but are still noticing whistling, Van Haaften Plumbing & Heating can assist you. It’s critical to get loose ductwork repaired without delay, because it can result in comfort problems in your house and inflate your gas costs.

6. Furnace Making a Grinding Noise

It’s not an encouraging 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. Shut down your furnace off right away and call our professionals at 641-628-3621 for help.
