When your furnace is running correctly, it should deliver warm air without generating too much noise. While it’s expected to notice your furnace making noise as it begins running, other noises are indicating your furnace should get immediate professional support.

Here are some of the most frequent furnace noises and what they can be signaling. If your furnace is making an odd noise, our friendly heating pros are here to assist with the best furnace repair in West Palm Beach, Florida.

1. Furnace Making a Banging Noise

You might have a critical issue 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 include gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over the years, so that’s why it’s critical to schedule seasonal furnace maintenance with The Air Squad. One of the jobs our pros do during this work is clean your furnace’s burners. When this component gets dirty, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The resulting gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into warmth. Any cracks in it can discharge carbon monoxide, which is ordinarily emitted outside. This dangerous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, The Air Squad recommends turning it off and calling us at 561-223-8489. Too much natural gas in your furnace or a fractured heat exchanger are dangerous issues that require prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide hot air across your home. If the ductwork wasn’t installed properly or is aging, 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. Call The Air Squad at 561-223-8489 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently indicates an electrical problem, 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 needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes warm or chilly air across your space, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be the result of something small, like an unsecure screw, or something critical, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 561-223-8489 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to tell you it requires some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing might need to be greased. We are aware that maintenance often slips your mind, but our pros can get your furnace heating 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 may also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve examined your vents but are still hearing whistling, The Air Squad can provide support. It’s important to get loose ductwork repaired quickly, as it can result in comfort issues in your home and drive up your gas bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive 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 right away and call our professionals at 561-223-8489 for assistance.
