1. Furnace Making a Banging Noise

You might have an urgent problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a few problems. These range from gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy as time passes, so that’s why it’s essential to set annual furnace maintenance with Aggressive Mechanical. One of the things our pros complete during this appointment is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes more time. The subsequent gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into warmth. Any cracks in it can leak carbon monoxide, which is normally emitted outdoors. This hazardous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Aggressive Mechanical recommends turning it off and contacting us at 732-806-5536. Significant natural gas in your furnace or a cracked heat exchanger are hazardous problems that should get prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide hot air across your home. If the ductwork wasn’t designed correctly or is aging, it can make a lot of noise when your furnace is heating. This might be the issue if your furnace makes a banging noise when it shuts off. Contact Aggressive Mechanical at 732-806-5536 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or cold air across your space, and a capacitor, which triggers the motor. If either of these components are failing, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be the result of something minor, like an unsecure screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating professionals at 732-806-5536 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, 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 out or a bearing may need to be lubed. We realize that maintenance sometimes slips your mind, but our techs can get your furnace running quietly again fast.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing noise, Aggressive Mechanical can help. It’s essential to get loose ductwork fixed quickly, as it can create comfort problems in your residence and drive up your gas expenses.

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 often means there’s trouble with your furnace’s blower. Shut down your furnace off now and call us at 732-806-5536 for help.
