When your furnace is operating correctly, it should give heat without creating too much disruption. While it’s common to catch your furnace making noise as it begins running, other noises are showing your furnace should get immediate professional help.

Here are some of the most reported furnace noises and what they can be indicating. If your furnace is making an odd noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Beckley, West Virginia.

1. Furnace Makes Banging or Knocking Sounds

You could have an urgent problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a few problems. These include gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy over the years, so that’s why it’s important to book annual furnace maintenance with Appalachian Heating. One of the jobs our technicians do during this appointment is clean your furnace’s burners. When this piece gets dirty, you could hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can discharge carbon monoxide, which is normally released outside. This dangerous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Appalachian Heating advises turning it off and calling us at 304-707-0600. Too much natural gas in your furnace or a broken heat exchanger are dangerous troubles that should get fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide heated air across your home. If the ductwork wasn’t installed right or is getting old, it can be loud when your furnace is heating. This can be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Appalachian Heating at 304-707-0600 and we’ll pinpoint the problem.

2. Furnace Makes a Buzzing Sound

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often indicates 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 isn’t tight enough, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes warm or chilly air throughout your space, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be due to something little, like a loose screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and calling our heating professionals at 304-707-0600 for help.

4. Furnace Making a Squealing Noise

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

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You may also be aware of whistling while the furnace is on if a floor vent isn’t tight. If you’ve looked at your vents but are still hearing sound, Appalachian Heating can provide support. It’s important to get loose ductwork taken care of without delay, since it can create comfort issues in your house and increase your energy costs.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound typically means there’s trouble with your furnace’s blower. Turn off your furnace off immediately and call us at 304-707-0600 for help.
