When your furnace is running like it should, it should provide heat without making too much sound. While it’s normal to notice your furnace making noise as it starts up, other sounds are indicating your furnace requires immediate professional help.
Here are some of the most reported furnace noises and what they might be signaling. If your furnace is making an atypical noise, our friendly heating professionals are here to help with the best furnace repair in Bend, OR.
1. Furnace Making a Banging Noise
You may have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a few problems. These include gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over time, so that’s why it’s critical to book yearly furnace maintenance with Tri County Climate Control LLC. One of the jobs our professionals complete during this service is clean your furnace’s burners. When this component gets dirty, you could hear your furnace making a loud rumbling noise after ignition takes more time. The resulting gas buildup can break your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can emit carbon monoxide, which is ordinarily emitted outdoors. This toxic gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Tri County Climate Control LLC advises turning it off and reaching us at 541-238-2797. Excessive natural gas in your furnace or a ruptured heat exchanger are critical troubles that should get prompt attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to provide heated air around your house. If the ductwork wasn’t designed right or is getting dated, it can be loud when your furnace is heating. This can be the problem if your furnace makes a banging noise when it shuts off. Call Tri County Climate Control LLC at 541-238-2797 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually means there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the proper 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 works with a blower motor, which moves heated or cooled air throughout your rooms, and a capacitor, which triggers the motor. If either of these pieces are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be due to something minor, like a loose screw, or something major, like a broken component. In either case, we urge you to shut your furnace off and contacting our heating pros at 541-238-2797 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to get your attention it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing could need to be lubed. We realize that maintenance frequently slips your mind, but our pros can get your furnace heating quietly again quickly.
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 may also notice whistling while the furnace is on if a floor vent is loose. If you’ve checked your vents but are still sensing noise, Tri County Climate Control LLC can help. It’s important to get loose ductwork fixed quickly, as it can create comfort troubles in your residence and increase your gas bills.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal noise frequently means there’s an issue with your furnace’s blower. Shut down your furnace off instantly and contact our pros at 541-238-2797 for support.
