Here are some of the most reported furnace noises and what they might be signaling. If your furnace is making a weird noise, our friendly heating pros are here to fix the problem with the best furnace repair in Neptune City, New Jersey.

1. Furnace Making a Banging Noise

You may have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a couple of problems. These include gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s critical to book seasonal furnace maintenance with Aggressive Mechanical. One of the things our professionals do during this service is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup may break your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can discharge carbon monoxide, which is normally emitted outdoors. This hazardous gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Aggressive Mechanical recommends turning it off and calling us at 732-806-5536. Too much natural gas in your furnace or a broken heat exchanger are critical troubles that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide heated air throughout your home. If the ductwork wasn’t put in properly 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 delay calling us. A buzzing sound frequently is telling you there’s an electrical problem, 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 is loose, you could hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends warm or chilly air across your home, and a capacitor, which starts the motor. If either of these parts are failing, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be due to something little, like an unsecure screw, or something major, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating specialists 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 heating, it’s making an effort to get your attention it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be lubed. We realize that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You might also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve examined your vents but are still sensing noise, Aggressive Mechanical can assist you. It’s important to get loose ductwork repaired without delay, as it can create comfort troubles in your home and increase your heating 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 typically means there’s trouble with your furnace’s blower. Turn off your furnace off right away and reach our professionals at 732-806-5536 for help.
