When your furnace is running properly, it should provide warm air without creating too much sound. While it’s common to notice your furnace making noise as it begins running, other noises are indicating your furnace requires immediate professional support.

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

1. Furnace Makes Banging or Knocking Sounds

You may have an urgent problem 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 a couple of problems. These range from gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over time, so that’s why it’s critical to set annual furnace maintenance with Air Concepts of Middle Georgia. One of the things our technicians do during this appointment is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes more time. The resulting gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can emit carbon monoxide, which is ordinarily vented outdoors. This toxic gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Air Concepts of Middle Georgia recommends turning it off and reaching us at 478-200-5689. Excessive natural gas in your furnace or a cracked heat exchanger are dangerous issues that should get prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver hot air around your home. If the ductwork wasn’t put in right or is aging, it can make a lot of noise when your furnace is heating. This might be the issue if your furnace makes a banging noise when it shuts off. Call Air Concepts of Middle Georgia at 478-200-5689 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cooled air across your residence, and a capacitor, which turns on the motor. If either of these parts are fading, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be related to something little, like an unsecure screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and getting in touch with our heating pros at 478-200-5689 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to alert you it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing could need to be lubricated. We are aware that maintenance sometimes slips your mind, but our techs can get your furnace operating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s typically due to 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 noticing whistling, Air Concepts of Middle Georgia can assist you. It’s essential to get loose ductwork fixed quickly, because it can make comfort troubles in your home and increase your heating costs.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal racket typically means there’s trouble with your furnace’s blower. Turn off your furnace off promptly and call our professionals at 478-200-5689 for assistance.
