When your furnace is running like it should, it should deliver warmth without generating too much sound. While it’s normal to notice your furnace making noise as it begins running, other disruptions are signaling your furnace needs immediate professional support.

Here are some of the most reported furnace noises and what they could be indicating. If your furnace is making an odd noise, our friendly heating professionals are here to assist with the best furnace repair in Milledgeville and Middle Georgia, Georgia.

1. Furnace Makes Banging or Knocking Sounds

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

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over the years, so that’s why it’s critical to book yearly furnace maintenance with Air Concepts of Middle Georgia. One of the things our pros do during this service is clean your furnace’s burners. When this part gets grimy, you might hear your furnace making a loud rumbling noise when ignition takes more time. The subsequent gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any fractures in it can leak carbon monoxide, which is regularly released outdoors. This hazardous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Air Concepts of Middle Georgia urges you to turn it off and calling us at 478-200-5689. Significant natural gas in your furnace or a fractured heat exchanger are serious problems that necessitate prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver hot air across your home. If the ductwork wasn’t installed properly or is getting old, it can be loud when your furnace is on. This could be the problem if your furnace makes a banging noise when it shuts off. Contact Air Concepts of Middle Georgia at 478-200-5689 and we’ll determine 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 typically indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you might hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or cold air across your space, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be related to something small, like a loose screw, or something critical, like a broken part. In either case, we recommend shutting off your furnace and calling our heating specialists at 478-200-5689 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to tell you it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be lubricated. We are aware that maintenance sometimes slips your mind, but our pros can get your furnace operating quietly again quickly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still noticing whistling, Air Concepts of Middle Georgia can assist you. It’s important to get loose ductwork taken care of without delay, as it can create comfort issues in your home and increase your heating expenses.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal noise typically means there’s an issue with your furnace’s blower. Turn off your furnace off now and call us at 478-200-5689 for help.
