When your furnace is working correctly, it should give heat without making too much disruption. While it’s expected to hear your furnace making noise as it turns on, other sounds are signaling your furnace needs immediate professional help.

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

1. Furnace Makes Banging or Knocking Sounds

You could have an urgent problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a couple of problems. These range from gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over time, so that’s why it’s essential to book seasonal furnace maintenance with Tri County Climate Control LLC. One of the things our professionals perform during this service is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise if ignition takes longer than normal. The subsequent gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into heat. Any breaks in it can emit carbon monoxide, which is normally released away from your home. This hazardous gas can be lethal in large concentrations.

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

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move hot air across your residence. If the ductwork wasn’t put in correctly or is getting old, it can be loud when your furnace is heating. This might 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 hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the correct voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or cooled air across your rooms, and a capacitor, which triggers the motor. If either of these parts are fading, 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 can be due to something little, like a loose screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating professionals at 541-238-2797 for support.

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 requires some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing might need to be greased. We realize that maintenance often slips your mind, but our pros 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 frequently the result of an air leak in your ductwork. You might also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve examined your vents but are still sensing whistling, Tri County Climate Control LLC can provide support. It’s important to get loose ductwork fixed without delay, as it can make comfort problems in your house and increase your utility bills.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal noise typically means there’s an issue with your furnace’s blower. Switch off your furnace off now and reach our professionals at 541-238-2797 for help.
