When your furnace is working correctly, it should provide warmth without making too much noise. While it’s normal to notice your furnace making noise as it starts up, other sounds are indicating your furnace should get immediate professional support.

Here are some of the most frequent furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to help with the best furnace repair in Macon, Georgia.

1. Furnace Makes Banging or Knocking Sounds

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

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over the years, so that’s why it’s critical to schedule seasonal furnace maintenance with Air Temperature Control. One of the jobs our professionals perform during this service is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise if ignition is delayed. The resulting gas buildup may crack your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can discharge carbon monoxide, which is regularly released outside. This hazardous gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Air Temperature Control advises turning it off and reaching us at 478-202-3170. Significant natural gas in your furnace or a broken heat exchanger are critical problems that should get fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver heated air throughout your residence. If the ductwork wasn’t put in right or is aging, it can be noisy when your furnace is on. This may be the case 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 figure out the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace uses an internal transformer to work on the correct 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 moves heated or cooled air around your rooms, and a capacitor, which triggers the motor. If either of these parts are going out, they will buzz when the furnace starts.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be due to something little, like a loose screw, or something major, like a broken component. In either case, we urge you to shut your furnace off and contacting our heating specialists at 478-202-3170 for help.

4. Furnace Squeals

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 last couple of years, belts could be worn out or a bearing might need to be lubricated. We realize that maintenance sometimes slips your mind, but our pros can get your furnace heating quietly again quickly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You could also hear whistling while the furnace is working 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 repaired without delay, because it can make comfort troubles in your home and drive up 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 typically means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and reach our professionals at 478-202-3170 for assistance.
