When your furnace is working correctly, it should deliver heat without generating too much sound. While it’s common to catch your furnace making noise as it begins running, other disruptions are showing your furnace needs immediate professional help.

Here are some of the most reported furnace noises and what they might mean. If your furnace is making a strange noise, our friendly heating specialists are here to assist with the best furnace repair in Columbia, Mississippi.

1. Furnace Makes Banging or Knocking Sounds

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

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over time, so that’s why it’s important to book annual furnace maintenance with Watts Electric & AC. One of the jobs our technicians do during this work is clean your furnace’s burners. When this component gets grubby, you might hear your furnace making a loud rumbling noise after ignition is delayed. The ensuing gas buildup can break your furnace’s heat exchanger, where natural gas transforms into warmth. Any fractures in it can emit carbon monoxide, which is regularly released outdoors. This hazardous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Watts Electric & AC recommends turning it off and calling us at 601-736-7362. Too much natural gas in your furnace or a ruptured heat exchanger are dangerous problems that should get fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide hot air across your house. If the ductwork wasn’t put in correctly or is getting dated, it can be noisy when your furnace is on. This could be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Watts Electric & AC at 601-736-7362 and we’ll determine the problem.

2. Furnace Buzzes Constantly

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

Your furnace relies on an internal transformer to run 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 has a blower motor, which moves heated or chilly air across your residence, and a capacitor, which turns on the motor. If either of these components are fading, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be related to something minor, like an unfastened screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating specialists at 601-736-7362 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to alert you it requires some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubricated. We realize that maintenance frequently slips your mind, but our pros can get your furnace running quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting 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 isn’t tight. If you’ve checked your vents but are still noticing sound, Watts Electric & AC can provide support. It’s essential to get loose ductwork taken care of without delay, because it can make comfort issues in your home and inflate your heating 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 sound typically means there’s an issue with your furnace’s blower. Shut down your furnace off immediately and reach our pros at 601-736-7362 for assistance.
