When your furnace is working properly, it should deliver heat without making too much noise. While it’s expected to catch your furnace making noise as it starts up, other noises are indicating your furnace should get immediate professional assistance.

Here are some of the most reported furnace noises and what they can mean. If your furnace is making an odd noise, our friendly heating professionals are here to assist with the best furnace repair in Bend, Oregon.

1. Furnace Makes a Banging Sound

You might have a serious problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a couple of problems. These involve gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty as time passes, so that’s why it’s important to set seasonal furnace maintenance with Tri County Climate Control LLC. One of the jobs our technicians do during this service is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into heat. Any fractures in it can leak carbon monoxide, which is regularly vented outdoors. This hazardous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Tri County Climate Control LLC urges you to turn it off and reaching us at 541-238-2797. Significant natural gas in your furnace or a cracked heat exchanger are dangerous issues that should get prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide warm air throughout your house. If the ductwork wasn’t designed properly or is aging, it can make a lot of noise when your furnace is on. This can be the issue 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 pinpoint 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 frequently indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the correct voltage. If wires or the box is loose, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves heated or chilly air around your space, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be related to something minor, like a loose screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and calling our heating specialists at 541-238-2797 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to tell you it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubricated. We know that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You might also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve examined your vents but are still sensing noise, Tri County Climate Control LLC can help. It’s essential to get loose ductwork taken care of fast, because it can make comfort troubles in your house and inflate your utility expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal noise usually means there’s a problem with your furnace’s blower. Turn off your furnace off now and call our professionals at 541-238-2797 for support.
