When your furnace is running properly, it should deliver heat without creating too much disruption. While it’s normal to notice your furnace making noise as it begins running, other noises are indicating your furnace needs immediate professional help.

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

1. Furnace Makes a Banging Sound

You could have a serious problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be several problems. These involve gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over the years, so that’s why it’s critical to schedule yearly furnace maintenance with Covington Air Systems. One of the jobs our professionals perform during this work is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise after ignition is delayed. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can leak carbon monoxide, which is regularly released away from your home. This hazardous gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Covington Air Systems recommends turning it off and reaching us at (770) 462-5319. Excessive natural gas in your furnace or a broken heat exchanger are hazardous problems that should get immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move heated air around your residence. If the ductwork wasn’t designed properly or is getting old, it can be noisy when your furnace is heating. This might be the issue if your furnace makes a banging noise when it shuts off. Contact Covington Air Systems at (770) 462-5319 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically means there’s an electrical issue, 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 needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes hot or chilly air throughout your rooms, and a capacitor, which starts the motor. If either of these parts are going out, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be the result of something small, like a loose screw, or something serious, like a broken part. In either case, we advise shutting your furnace off and contacting our heating pros at (770) 462-5319 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to tell you it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubed. We know that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again quickly.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You may also hear whistling while the furnace is on if a floor vent isn’t tight. If you’ve examined your vents but are still hearing whistling, Covington Air Systems can provide support. It’s important to get loose ductwork fixed without delay, as it can result in comfort issues in your residence and drive up your gas expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal racket typically means there’s a problem with your furnace’s blower. Shut down your furnace off right away and reach our professionals at (770) 462-5319 for help.
