When your furnace is running properly, it should give heat without creating too much sound. While it’s expected to notice your furnace making noise as it begins running, other disruptions are showing your furnace should get immediate professional support.

Here are some of the most common furnace noises and what they can mean. If your furnace is making an atypical noise, our friendly heating specialists are here to help with the best furnace repair in Lexington, North Carolina.

1. Furnace Makes a Banging Sound

You might have a serious issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a couple of problems. These range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over time, so that’s why it’s important to schedule yearly furnace maintenance with James Heating & A/C, Inc. One of the jobs our technicians do during this appointment is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise when ignition takes more time. The subsequent gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can emit carbon monoxide, which is regularly released outdoors. This toxic gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, James Heating & A/C, Inc urges you to turn it off and reaching us at 336-853-6070. Excessive natural gas in your furnace or a cracked heat exchanger are hazardous issues that necessitate fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver warm air around your home. If the ductwork wasn’t put in properly or is getting old, it can be noisy when your furnace runs. This may be the problem if your furnace makes a banging noise when it shuts off. Call James Heating & A/C, Inc at 336-853-6070 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace uses an internal transformer to work on the proper voltage. If wires or the box isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends heated or chilly air across your rooms, and a capacitor, which starts the motor. If either of these components are going out, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be related to something small, like a loose screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating specialists at 336-853-6070 for assistance.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to tell you it needs some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing might need to be greased. We realize that maintenance frequently slips your mind, but our technicians can get your furnace running quietly again fast.

5. Furnace Whistles

When you’re noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You may also hear whistling while the furnace is working if a floor vent is loose. If you’ve checked your vents but are still hearing sound, James Heating & A/C, Inc can assist you. It’s essential to get loose ductwork taken care of fast, as it can make comfort troubles in your residence and increase your gas bills.

6. Furnace Making a Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal sound frequently means there’s an issue with your furnace’s blower. Switch off your furnace off right away and contact our pros at 336-853-6070 for assistance.
