When your furnace is running correctly, it should give heat without creating too much noise. While it’s expected to catch your furnace making noise as it begins running, other noises are indicating your furnace requires immediate professional support.

Here are some of the most frequent furnace noises and what they might be indicating. If your furnace is making an atypical noise, our friendly heating specialists are here to assist with the best furnace repair in Lansing, Kansas.

1. Furnace Makes a Banging Sound

You might have a critical problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be several problems. These involve gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s important to set seasonal furnace maintenance with Everest Heating & Cooling. One of the tasks our technicians perform during this work is clean your furnace’s burners. When this part gets grimy, you may hear your furnace making a loud rumbling noise after ignition takes more time. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can discharge carbon monoxide, which is normally vented outside. This hazardous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Everest Heating & Cooling recommends turning it off and contacting us at 913-845-9463. Too much natural gas in your furnace or a fractured heat exchanger are critical problems that should get immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide hot air throughout your home. If the ductwork wasn’t put in properly or is aging, it can be noisy when your furnace is on. This could be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Everest Heating & Cooling at 913-845-9463 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 typically means there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the right voltage. If wires or the box isn’t tight enough, you may notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends hot or chilly air across your residence, and a capacitor, which starts the motor. If either of these parts are fading, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be related to something little, like an unfastened screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating professionals at 913-845-9463 for help.

4. Furnace Squeals

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 skipped furnace maintenance recently, belts could be worn out or a bearing may need to be greased. We know that maintenance often slips your mind, but our technicians can get your furnace heating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You could also hear whistling while the furnace is running if a floor vent isn’t secure. If you’ve examined your vents but are still hearing sound, Everest Heating & Cooling can help. It’s critical to get loose ductwork fixed without delay, as it can result in comfort problems in your home and increase your energy bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal sound frequently means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and call our professionals at 913-845-9463 for help.
