Is Your Furnace Making a Loud Buzzing Noise? Here’s What You Can Do About It.

Is your furnace making a loud buzzing sound? Or a crackling or humming sound? There are a few common noises that may be coming from your furnace. Read on for these and more issues, what they mean and how you can remedy them.

Is Your Furnace Making a Loud Buzzing Noise?

  • Your furnace has a transformer box. If it is dying or not secured properly, it can buzz. You can fix a poorly mounted box with a screw driver. However, if the transformer itself needs to be replaced, you must call in a professional.
  • The capacitor might also be broken which could cause the motor to buzz. The capacitor is a silver device that stores electricity and helps the motor start. Call in a professional to replace the capacitor, which is quite easy and inexpensive to replace.
  • If the blower motor has blown, it will often buzz or hum when the power to the furnace is turned on. Replacing a motor is complicated and requires you to disconnect the old wires and remove the motor shaft from the blower housing. This is a job for a professional HVAC specialist.

Other Common Furnace Noises

Crackling Noise:

If your furnace is making a crackling noise, it could be operating normally. Just after your furnace turns off you may hear a crackling sound coming from it. This sound could be the ducts cooling after operation. Pay attention to when the sound occurs. If it’s persistent, or occurs when the furnace is in use, it might be a sign of a bigger problem.

Knocking Noise:

Your furnace making a knocking noise or a loud pop or bang when starting up could mean problems with the expanding and contracting of your air ducts. They may have issues that need to be repaired such as undersized ducts, flimsy ducts, closed vents or a clogged air filter.

If dirt builds in your furnace burners it can delay ignition and cause gas to build up. When it does ignite you will hear a loud pop or bang. If not checked out, this process could crack or damage your heat exchanger, which can be expensive to repair.

Humming Noise:

Your furnace making a humming noise could simply be the blower motor. This sound could be a result of improper lubrication. Turn off your motor and check it when it is cooled enough to touch.

Clicking Noise:

If your furnace is making a clicking noise while running it will need immediate attention. This sound could be an indication of a faulty flame sensor, or a problem between the ignition and the gas.

These are just some of the problematic noises that your furnace can make. If you hear any noises that concern you, please don’t hesitate to get your furnace checked out by a professional at D&B ClimateCare.
