When your furnace is running correctly, it should provide heat without generating too much noise. While it’s normal to notice your furnace making noise as it begins running, other sounds are signaling your furnace requires immediate professional assistance.

Here are some of the most reported furnace noises and what they can mean. If your furnace is making a weird noise, our friendly heating specialists are here to help with the best furnace repair in Harrisonville and Raymore, Missouri.

1. Furnace Makes a Banging Sound

You may have an urgent 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 a few problems. These include gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty as time passes, so that’s why it’s essential to book routine furnace maintenance with Balance Point Heating & Cooling. One of the tasks our pros perform during this appointment is clean your furnace’s burners. When this part gets grimy, you might hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup might crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can leak carbon monoxide, which is regularly emitted away from your home. This dangerous gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Balance Point Heating & Cooling recommends turning it off and reaching us at 816-265-0448. Too much natural gas in your furnace or a cracked heat exchanger are dangerous troubles that should get immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide warm air across your home. If the ductwork wasn’t designed properly or is aging, it can be noisy when your furnace is on. This might be the issue if your furnace makes a banging noise when it shuts off. Call Balance Point Heating & Cooling at 816-265-0448 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends warm or cooled air across your residence, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be the result of something little, like a loose screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 816-265-0448 for assistance.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to get your attention it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be lubricated. We are aware that maintenance sometimes slips your mind, but our techs can get your furnace heating quietly again quickly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also hear whistling while the furnace is on if a floor vent is loose. If you’ve checked your vents but are still sensing whistling, Balance Point Heating & Cooling can help. It’s critical to get loose ductwork repaired without delay, because it can create comfort troubles in your house and drive up your utility bills.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket frequently means there’s trouble with your furnace’s blower. Switch off your furnace off instantly and contact our pros at 816-265-0448 for support.
