When your furnace is running like it should, it should give warm air without creating too much disruption. While it’s common to notice your furnace making noise as it begins running, other sounds are showing your furnace requires immediate professional support.

Here are some of the most reported furnace noises and what they can mean. If your furnace is making a weird noise, our friendly heating professionals are here to assist with the best furnace repair in Hudsonville, Michigan.

1. Furnace Makes Banging or Knocking Sounds

You may have a critical situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a few problems. These involve gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy as time passes, so that’s why it’s critical to book annual furnace maintenance with West Michigan Heating & Air Conditioning Services. One of the tasks our professionals perform during this service is clean your furnace’s burners. When this component gets grubby, you might hear your furnace making a loud rumbling noise after ignition takes more time. The following gas buildup may crack your furnace’s heat exchanger, where natural gas changes into heat. Any cracks in it can discharge carbon monoxide, which is ordinarily emitted outside. This dangerous gas can be deadly 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. Excessive natural gas in your furnace or a fractured heat exchanger are serious issues that should get prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move heated air around 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 problem 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 Makes a Buzzing Sound

If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the correct voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or cooled air around your rooms, and a capacitor, which turns on the motor. If either of these pieces are fading, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be due to something little, like an unsecure screw, or something major, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with our heating pros 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 running, it’s making an effort to get your attention it requires some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing might need to be lubricated. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace heating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting 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 operating if a floor vent is loose. If you’ve looked at your vents but are still sensing noise, West Michigan Heating & Air Conditioning Services can assist you. It’s critical to get loose ductwork repaired quickly, because it can result in comfort troubles in your home and increase your utility bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal noise often means there’s a problem with your furnace’s blower. Shut down your furnace off immediately and call our professionals at (616) 319-1436 for assistance.
