When your furnace is running properly, it should give warm air without making too much disruption. While it’s normal to notice your furnace making noise as it turns on, other sounds are signaling your furnace needs immediate professional support.
Here are some of the most common furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to assist with the best furnace repair in Hudsonville, Michigan.
1. Furnace Makes Banging or Knocking Sounds
You may have an urgent issue 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 few problems. These include gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy as time passes, so that’s why it’s important to book seasonal furnace maintenance with West Michigan Heating & Air Conditioning Services. One of the tasks our professionals do during this service is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise after ignition takes more time. The ensuing gas buildup might crack your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can leak carbon monoxide, which is regularly vented outside. This toxic 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 advises turning it off and contacting us at (616) 319-1436. Excessive natural gas in your furnace or a broken heat exchanger are critical troubles that require immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move warm air across your residence. If the ductwork wasn’t installed properly or is getting dated, it can make a lot of noise when your furnace is on. This may 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 pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently means there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the correct 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 sends heated or chilly air around your residence, and a capacitor, which turns on the motor. If either of these components are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be related to something minor, like an unfastened screw, or something serious, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating pros at (616) 319-1436 for help.
4. Furnace Is Making a High-Pitched Squealing Sound
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 recently, belts could be worn out or a bearing might need to be lubricated. We realize that maintenance often slips your mind, but our technicians can get your furnace operating quietly again rapidly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also hear whistling while the furnace is on if a floor vent isn’t tight. If you’ve checked your vents but are still sensing sound, West Michigan Heating & Air Conditioning Services can provide support. It’s important to get loose ductwork repaired fast, as it can create comfort troubles in your house and inflate your gas 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 trouble with your furnace’s blower. Shut down your furnace off now and reach our pros at (616) 319-1436 for assistance.
