When your furnace is operating properly, it should deliver heat without making too much noise. While it’s expected to catch your furnace making noise as it turns on, other disruptions are showing your furnace requires immediate professional support.

Here are some of the most reported furnace noises and what they could be signaling. If your furnace is making an atypical noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Hudsonville, Michigan.

1. Furnace Making a Banging Noise

You may have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a couple of problems. These range from gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over the years, so that’s why it’s essential to book routine furnace maintenance with West Michigan Heating & Air Conditioning Services. One of the tasks our techs do during this appointment is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise if ignition takes more time. The resulting gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can discharge carbon monoxide, which is normally emitted away from your home. This hazardous gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, West Michigan Heating & Air Conditioning Services urges you to turn it off and calling us at (616) 319-1436. Too much natural gas in your furnace or a fractured heat exchanger are hazardous problems that require prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide hot air across your residence. If the ductwork wasn’t installed properly or is getting old, it can be noisy when your furnace is heating. This might be the issue if your furnace makes a banging noise when it shuts off. Call West Michigan Heating & Air Conditioning Services at (616) 319-1436 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 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 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 hot or cooled air across your house, and a capacitor, which turns on 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 little, like a loose screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and calling our heating professionals at (616) 319-1436 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 skipped furnace maintenance recently, belts could be worn down or a bearing might need to be greased. We realize that maintenance frequently slips your mind, but our pros can get your furnace running quietly again quickly.

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 be aware of whistling while the furnace is running if a floor vent isn’t secure. If you’ve checked your vents but are still hearing sound, West Michigan Heating & Air Conditioning Services can provide support. It’s essential to get loose ductwork fixed quickly, because it can make comfort troubles in your home and inflate your gas bills.

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 typically means there’s an issue with your furnace’s blower. Switch off your furnace off instantly and call our professionals at (616) 319-1436 for help.
