When your furnace is operating correctly, it should deliver warmth without making too much sound. While it’s common to catch your furnace making noise as it turns on, other sounds are indicating your furnace needs immediate professional assistance.

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 Macon, Georgia.

1. Furnace Making a Banging Noise

You might have a critical issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be several problems. These involve gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over time, so that’s why it’s essential to book routine furnace maintenance with Air Temperature Control. One of the tasks our professionals do during this service is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can discharge carbon monoxide, which is ordinarily released outdoors. 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 calling us at 478-202-3170. Significant natural gas in your furnace or a broken heat exchanger are serious issues that require fast service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver heated air throughout your home. If the ductwork wasn’t installed right or is getting old, it can be noisy when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Contact Air Temperature Control at 478-202-3170 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to operate on the right voltage. If wires or the box isn’t tight enough, you may notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends warm or chilly air around your residence, and a capacitor, which turns on the motor. If either of these pieces 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 related to something minor, like a loose screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and contacting our heating pros at 478-202-3170 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to tell you it requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing may need to be greased. We realize that maintenance frequently slips your mind, but our pros can get your furnace heating quietly again fast.

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 could 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 sensing whistling, Air Temperature Control can help. It’s important to get loose ductwork fixed fast, since it can result in comfort problems in your home and drive up your gas bills.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal sound typically means there’s trouble with your furnace’s blower. Shut down your furnace off immediately and call our professionals at 478-202-3170 for help.
