When your furnace is running correctly, it should provide heat without making too much noise. While it’s normal to catch your furnace making noise as it turns on, other disruptions are showing your furnace should get immediate professional support.

Here are some of the most common furnace noises and what they might be indicating. If your furnace is making an atypical noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Des Moines, Iowa.

1. Furnace Making a Banging Noise

You might have a critical issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a couple of problems. These range from gas building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over the years, so that’s why it’s critical to schedule seasonal furnace maintenance with Heartland Heating & Cooling. One of the tasks our professionals complete during this appointment is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise after ignition is delayed. The resulting gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any cracks in it can leak carbon monoxide, which is regularly emitted outside. This toxic gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Heartland Heating & Cooling urges you to turn it off and reaching us at 515-344-3579. Excessive natural gas in your furnace or a cracked heat exchanger are hazardous issues that require immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver hot air throughout your residence. If the ductwork wasn’t put in properly or is getting dated, it can be noisy when your furnace is heating. This could be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Heartland Heating & Cooling at 515-344-3579 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often means there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the proper voltage. If wires or the box needs to be tightened, you may notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes warm or chilly air throughout your rooms, and a capacitor, which starts the motor. If either of these components 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 the result of something minor, like an unfastened screw, or something major, like a broken part. In either case, we advise shutting your furnace off and contacting our heating specialists at 515-344-3579 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to get your attention it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be greased. We know that maintenance sometimes slips your mind, but our technicians can get your furnace running quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve examined your vents but are still noticing sound, Heartland Heating & Cooling can help. It’s essential to get loose ductwork taken care of without delay, because it can result in comfort issues in your house and drive up your gas 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. Turn off your furnace off now and reach our pros at 515-344-3579 for assistance.
