When your furnace is working like it should, it should give warmth without making too much noise. While it’s expected to notice your furnace making noise as it begins running, other noises are signaling your furnace requires immediate professional support.

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

1. Furnace Makes a Banging Sound

You could have a serious situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate 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 gets filthy over the years, so that’s why it’s essential to schedule routine furnace maintenance with Just Komfort Heating & Cooling. One of the things our techs do during this work is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise after ignition takes more time. The following gas buildup might crack your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can emit carbon monoxide, which is regularly vented outside. This dangerous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Just Komfort Heating & Cooling advises turning it off and calling us at 458-206-0216. Too much natural gas in your furnace or a broken heat exchanger are hazardous problems that should get immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver heated air across your residence. If the ductwork wasn’t put in correctly or is getting dated, it can be noisy when your furnace is on. This might be the case if your furnace makes a banging noise when it shuts off. Contact Just Komfort Heating & Cooling at 458-206-0216 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually means there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes warm or cooled air throughout your home, and a capacitor, which triggers the motor. If either of these components are fading, they will buzz when the furnace starts.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be due to something small, like an unsecure screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 458-206-0216 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 trying to alert you it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be greased. We know that maintenance often slips your mind, but our techs can get your furnace heating quietly again fast.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s likely because 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 checked your vents but are still noticing whistling, Just Komfort Heating & Cooling can provide support. It’s critical to get loose ductwork repaired fast, since it can create comfort issues in your home and drive up your heating expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket typically means there’s trouble with your furnace’s blower. Switch off your furnace off promptly and call our professionals at 458-206-0216 for assistance.
