When your furnace is working like it should, it should give warm air without generating too much sound. While it’s expected to hear your furnace making noise as it turns on, other disruptions are signaling your furnace needs immediate professional help.

Here are some of the most frequent furnace noises and what they might be signaling. If your furnace is making a strange noise, our friendly heating professionals are here to assist with the best furnace repair in Newport, North Carolina.

1. Furnace Making a Banging Noise

You might have an urgent issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be several problems. These include gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy as time passes, so that’s why it’s critical to set annual furnace maintenance with Antonelli Comfort Solutions. One of the jobs our techs complete during this service is clean your furnace’s burners. When this component gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes more time. The following gas buildup can break your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can emit carbon monoxide, which is ordinarily released outside. This hazardous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Antonelli Comfort Solutions recommends turning it off and reaching us at 252-424-0803. Excessive natural gas in your furnace or a fractured heat exchanger are critical problems that require fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move heated air throughout your house. If the ductwork wasn’t designed right or is getting dated, it can be loud when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Contact Antonelli Comfort Solutions at 252-424-0803 and we’ll pinpoint 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 typically means there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the right voltage. If wires or the box isn’t tight enough, you might 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 triggers the motor. If either of these parts are fading, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be due to something minor, like an unsecure screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and calling our heating pros at 252-424-0803 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to get your attention it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubed. We know that maintenance often slips your mind, but our technicians can get your furnace heating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is running if a floor vent isn’t secure. If you’ve checked your vents but are still sensing whistling, Antonelli Comfort Solutions can help. It’s important to get loose ductwork fixed fast, because it can result in comfort troubles in your home and drive up your energy costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal noise frequently means there’s trouble with your furnace’s blower. Turn off your furnace off now and reach our professionals at 252-424-0803 for help.
