When your furnace is operating properly, it should provide warmth without creating too much noise. While it’s common to hear your furnace making noise as it begins running, other disruptions are indicating your furnace needs immediate professional support.

Here are some of the most common furnace noises and what they can be indicating. If your furnace is making a strange noise, our friendly heating specialists are here to help with the best furnace repair in Bend, Oregon.

1. Furnace Making a Banging Noise

You could have a critical problem 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 several problems. These involve gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy over the years, so that’s why it’s critical to schedule seasonal furnace maintenance with Tri County Climate Control LLC. One of the tasks our pros complete during this service is clean your furnace’s burners. When this piece gets dirty, you could hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any cracks in it can discharge carbon monoxide, which is ordinarily released outside. This toxic gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Tri County Climate Control LLC advises turning it off and contacting us at 541-238-2797. Excessive natural gas in your furnace or a fractured heat exchanger are dangerous troubles that require immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver warm air around your home. If the ductwork wasn’t designed correctly or is aging, 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 Tri County Climate Control LLC at 541-238-2797 and we’ll figure out 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 issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or cooled air throughout your home, and a capacitor, which triggers the motor. If either of these parts are fading, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be related to something small, like an unsecure screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating specialists at 541-238-2797 for support.

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 skipped furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubed. We know that maintenance sometimes slips your mind, but our techs can get your furnace running quietly again fast.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve examined your vents but are still hearing noise, Tri County Climate Control LLC can help. It’s essential to get loose ductwork taken care of fast, because it can make comfort issues in your residence and inflate your utility expenses.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal sound often means there’s an issue with your furnace’s blower. Shut down your furnace off immediately and reach us at 541-238-2797 for help.
