When your furnace is running properly, it should give warmth without generating too much noise. While it’s expected to catch your furnace making noise as it starts up, other sounds are showing your furnace needs immediate professional assistance.

Here are some of the most reported furnace noises and what they can be indicating. If your furnace is making a strange noise, our friendly heating pros are here to fix the problem with the best furnace repair in Eugene, Oregon.

1. Furnace Makes a Banging Sound

You could have an urgent problem on your hands if you’re detecting 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 range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty as time passes, so that’s why it’s important to set annual furnace maintenance with Home Comfort. One of the tasks our professionals do during this work is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes more time. The following gas buildup might crack your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can emit carbon monoxide, which is normally emitted outdoors. This hazardous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Home Comfort advises turning it off and reaching us at 541-345-2838. Too much natural gas in your furnace or a broken heat exchanger are critical problems that require prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move heated air around your house. If the ductwork wasn’t installed correctly or is aging, it can be loud when your furnace runs. This could be the problem if your furnace makes a banging noise when it shuts off. Call Home Comfort at 541-345-2838 and we’ll determine 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 usually means there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to run on the right voltage. If wires or the box needs to be tightened, you may 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 starts the motor. If either of these components are failing, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be due to something little, like an unsecure screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and contacting our heating professionals at 541-345-2838 for help.

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 making an effort to alert you it needs some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubed. We know that maintenance often 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 noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You may also hear whistling while the furnace is on if a floor vent is loose. If you’ve looked at your vents but are still noticing noise, Home Comfort can provide support. It’s essential to get loose ductwork taken care of quickly, as it can result in comfort problems in your home and inflate your utility expenses.

6. Furnace Making a Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket frequently means there’s trouble with your furnace’s blower. Shut down your furnace off now and contact our professionals at 541-345-2838 for help.
