When your furnace is running like it should, it should deliver warm air without creating too much sound. While it’s common to notice your furnace making noise as it begins running, other sounds are indicating your furnace needs immediate professional assistance.

Here are some of the most reported furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Kansas City, MO and Lansing, KS , Kansas.

1. Furnace Making a Banging Noise

You might have a critical 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 several problems. These include gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over the years, so that’s why it’s critical to book annual furnace maintenance with Everest Heating & Cooling. One of the jobs our professionals perform during this appointment is clean your furnace’s burners. When this part gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes more time. The resulting gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can emit carbon monoxide, which is normally released outdoors. This hazardous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Everest Heating & Cooling recommends turning it off and calling us at 913-845-9463. Significant natural gas in your furnace or a cracked heat exchanger are hazardous problems that necessitate prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide warm air across your residence. If the ductwork wasn’t designed right or is aging, it can be noisy when your furnace is heating. This might be the issue if your furnace makes a banging noise when it shuts off. Call Everest Heating & Cooling at 913-845-9463 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace uses an internal transformer to work on the proper voltage. If wires or the box is loose, you could notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes hot or cold air around your home, and a capacitor, which starts the motor. If either of these parts are going out, they will buzz when the furnace switches on.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be due to something minor, like a loose screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and calling our heating specialists at 913-845-9463 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to tell you it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubed. We are aware that maintenance sometimes slips your mind, but our techs can get your furnace running quietly again fast.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You may also notice whistling while the furnace is on if a floor vent isn’t tight. If you’ve checked your vents but are still sensing sound, Everest Heating & Cooling can assist you. It’s important to get loose ductwork taken care of quickly, because it can make comfort problems in your residence and drive up your energy expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound typically means there’s trouble with your furnace’s blower. Switch off your furnace off now and reach our pros at 913-845-9463 for assistance.
