When your furnace is operating correctly, it should provide heat without making too much disruption. While it’s common to catch your furnace making noise as it starts up, other disruptions are showing your furnace requires immediate professional assistance.

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

1. Furnace Makes Banging or Knocking Sounds

You could have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These include gas accumulating 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 important to book routine furnace maintenance with West Michigan Heating & Air Conditioning Services. One of the tasks our professionals do during this appointment is clean your furnace’s burners. When this part gets grimy, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The subsequent gas buildup may break your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can emit carbon monoxide, which is regularly emitted away from your home. This hazardous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, West Michigan Heating & Air Conditioning Services recommends turning it off and calling us at (616) 319-1436. Significant natural gas in your furnace or a ruptured heat exchanger are dangerous troubles that require immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver warm air around your house. If the ductwork wasn’t installed properly or is getting dated, it can make a lot of noise when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Get in touch with 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 means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the correct voltage. If wires or the box needs to be tightened, you may hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves warm or chilly air around your space, and a capacitor, which triggers the motor. If either of these pieces are going out, they will buzz when the furnace starts.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be due to something little, like a loose screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating pros at (616) 319-1436 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to tell you it requires some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing may need to be lubed. We realize that maintenance sometimes slips your mind, but our professionals can get your furnace operating quietly again fast.

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 be aware of whistling while the furnace is operating if a floor vent isn’t tight. If you’ve examined your vents but are still hearing whistling, West Michigan Heating & Air Conditioning Services can help. It’s critical to get loose ductwork fixed quickly, because it can create comfort problems in your residence and increase your gas expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal noise usually means there’s trouble with your furnace’s blower. Turn off your furnace off right away and reach our pros at (616) 319-1436 for help.
