When your furnace is operating correctly, it should provide heat without generating too much noise. While it’s normal to hear your furnace making noise as it starts up, other disruptions are indicating your furnace needs immediate professional help.

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

1. Furnace Makes a Banging Sound

You may have a serious problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a few problems. These involve gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over time, so that’s why it’s essential to set annual furnace maintenance with West Michigan Heating & Air Conditioning Services. One of the tasks our pros perform during this service is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can discharge carbon monoxide, which is ordinarily vented 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, West Michigan Heating & Air Conditioning Services advises turning it off and calling us at (616) 319-1436. Too much natural gas in your furnace or a cracked heat exchanger are serious issues that necessitate prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move hot air around your home. If the ductwork wasn’t designed properly or is getting old, it can make a lot of noise when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Contact West Michigan Heating & Air Conditioning Services at (616) 319-1436 and we’ll determine the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the right voltage. If wires or the box isn’t tight enough, you may notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or cooled air around your house, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be due to something minor, like an unfastened screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and contacting our heating specialists at (616) 319-1436 for assistance.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to alert you it needs 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 lubed. We are aware that maintenance frequently slips your mind, but our techs can get your furnace heating quietly again quickly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You might also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve examined your vents but are still noticing whistling, West Michigan Heating & Air Conditioning Services can help. It’s critical to get loose ductwork repaired quickly, since it can make comfort problems in your residence and drive up your energy bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise frequently means there’s a problem with your furnace’s blower. Shut down your furnace off promptly and call our pros at (616) 319-1436 for help.
