When your furnace is operating correctly, it should provide warm air without creating too much noise. While it’s common to catch your furnace making noise as it turns on, other sounds are showing your furnace should get immediate professional help.

Here are some of the most frequent furnace noises and what they might mean. If your furnace is making an atypical noise, our friendly heating specialists are here to help with the best furnace repair in Covington, Georgia.

1. Furnace Makes Banging or Knocking Sounds

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

Banging Sounds Coming from Your Furnace

Your heating system turns filthy as time passes, so that’s why it’s important to set annual furnace maintenance with Covington Air Systems. One of the things our professionals perform during this service is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise after ignition takes more time. The following gas buildup might fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can emit carbon monoxide, which is regularly emitted outdoors. This toxic gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Covington Air Systems recommends turning it off and reaching us at (770) 462-5319. Significant natural gas in your furnace or a cracked heat exchanger are serious problems that necessitate fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver heated air around your home. If the ductwork wasn’t designed right or is getting dated, it can be loud when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Call Covington Air Systems at (770) 462-5319 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes heated or cold air throughout your rooms, and a capacitor, which triggers the motor. If either of these components are going out, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be the result of something small, like an unsecure screw, or something major, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with our heating professionals at (770) 462-5319 for help.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it requires some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing may need to be lubricated. We are aware that maintenance frequently slips your mind, but our technicians can get your furnace running quietly again rapidly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also hear whistling while the furnace is working if a floor vent isn’t secure. If you’ve checked your vents but are still sensing whistling, Covington Air Systems can help. It’s essential to get loose ductwork repaired without delay, because it can create comfort issues in your home and inflate your energy bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good 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 promptly and contact us at (770) 462-5319 for assistance.
