Here are some of the most reported furnace noises and what they could mean. If your furnace is making an odd noise, our friendly heating pros are here to assist with the best furnace repair in Wyandotte, Michigan .
1. Furnace Makes a Banging Sound
You may have a critical problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may 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 becomes dirty over time, so that’s why it’s essential to schedule annual furnace maintenance with Gee & Missler Heating & Air Conditioning. One of the tasks our pros do during this work is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The following gas buildup might crack your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can discharge carbon monoxide, which is regularly vented outside. This hazardous gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Gee & Missler Heating & Air Conditioning urges you to turn it off and contacting us at 734-284-1224. Significant natural gas in your furnace or a broken heat exchanger are serious troubles that should get immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move warm air throughout your house. If the ductwork wasn’t installed properly or is getting old, it can make a lot of noise when your furnace is heating. This can be the issue if your furnace makes a banging noise when it shuts off. Call Gee & Missler Heating & Air Conditioning at 734-284-1224 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often indicates an electrical issue, 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 may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends heated or cooled air across your rooms, and a capacitor, which starts the motor. If either of these parts are going out, they will buzz when the furnace turns on.
3. Furnace Rattles
If your furnace is making a rattling noise, it can be the result of something minor, like an unsecure screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating specialists at 734-284-1224 for support.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to alert you it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing could need to be greased. We realize that maintenance frequently slips your mind, but our techs can get your furnace operating quietly again rapidly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re hearing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You may also notice whistling while the furnace is operating if a floor vent isn’t tight. If you’ve checked your vents but are still sensing whistling, Gee & Missler Heating & Air Conditioning can provide support. It’s critical to get loose ductwork repaired without delay, as it can make comfort troubles in your house and increase your gas expenses.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound frequently means there’s trouble with your furnace’s blower. Shut down your furnace off immediately and call our professionals at 734-284-1224 for assistance.
