When your furnace is operating like it should, it should deliver heat without creating too much disruption. While it’s normal to notice your furnace making noise as it starts up, other disruptions are showing your furnace needs immediate professional assistance.

Here are some of the most common furnace noises and what they might mean. If your furnace is making a weird noise, our friendly heating professionals are here to assist with the best furnace repair in Macon, Georgia.

1. Furnace Makes a Banging Sound

You might have a serious problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a couple of problems. These involve gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy over the years, so that’s why it’s important to book yearly furnace maintenance with Air Temperature Control. One of the things our pros complete during this appointment is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup can fracture your furnace’s heat exchanger, where natural gas turns into warmth. Any cracks in it can emit carbon monoxide, which is normally emitted outside. This hazardous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Air Temperature Control recommends turning it off and contacting us at 478-202-3170. Too much natural gas in your furnace or a cracked heat exchanger are critical problems that require immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move heated air around your house. If the ductwork wasn’t installed right or is getting dated, it can be loud when your furnace is heating. This could be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Air Temperature Control at 478-202-3170 and we’ll determine the problem.

2. Furnace Makes a Buzzing Sound

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically means there’s 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 isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or cooled air across your house, and a capacitor, which starts the motor. If either of these components are fading, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be due to something little, like a loose screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 478-202-3170 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to alert you it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubed. We are aware that maintenance frequently slips your mind, but our techs can get your furnace operating quietly again fast.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also notice whistling while the furnace is on if a floor vent isn’t tight. If you’ve examined your vents but are still sensing sound, Air Temperature Control can provide support. It’s critical to get loose ductwork fixed without delay, since it can result in comfort problems in your house and inflate your gas bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise frequently means there’s trouble with your furnace’s blower. Shut down your furnace off immediately and contact our pros at 478-202-3170 for assistance.
