When your furnace is operating correctly, it should give warmth without making too much noise. While it’s expected to catch your furnace making noise as it begins running, other noises are indicating your furnace needs immediate professional help.

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

1. Furnace Makes a Banging Sound

You could have a serious situation 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 several problems. These involve gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over time, so that’s why it’s important to schedule yearly furnace maintenance with Everest Heating & Cooling. One of the tasks our professionals complete during this work is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup might break your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can discharge carbon monoxide, which is ordinarily released outdoors. This hazardous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Everest Heating & Cooling advises turning it off and reaching us at 913-845-9463. Significant natural gas in your furnace or a broken heat exchanger are dangerous issues that necessitate fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move warm air around your home. If the ductwork wasn’t installed right or is getting dated, it can make a lot of noise when your furnace runs. This may 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 figure out the problem.

2. Furnace Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically 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 uses a blower motor, which moves hot or chilly air across your house, and a capacitor, which turns on the motor. If either of these pieces are fading, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be related to something small, like a loose screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating pros at 913-845-9463 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing could need to be greased. We are aware that maintenance sometimes slips your mind, but our technicians can get your furnace running quietly again fast.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You might also notice whistling while the furnace is operating if a floor vent isn’t tight. If you’ve examined your vents but are still hearing whistling, Everest Heating & Cooling can provide support. It’s essential to get loose ductwork taken care of quickly, since it can create comfort issues in your home and drive up your energy costs.

6. Furnace Making a Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal racket often means there’s a problem with your furnace’s blower. Switch off your furnace off immediately and call our pros at 913-845-9463 for assistance.
