Understanding the Sounds Your Furnace Makes

No one wants to deal with furnace making noise when the temperatures drop and the need for warmth rises. Noisy furnaces are not only obnoxious, but can be a sign of trouble – and unfortunately, troubleshooting the cause can be a difficult task. In this article, we’ll tackle the ins and outs of noisy furnace problems, and provide some helpful guidance on when it is time to call a professional technician.

Furnace Noises and What They Mean

Furnaces can exhibit a variety of noises such as buzzing, clanging, whirring, and more, each indicative of its own problem. Knowing what these sound disturbances mean can help you troubleshoot the problem, and determine whether you need a professional technician or not.


Buzzing furnaces are usually caused by a loose cover or misaligned parts, but could also be caused by loose wiring or a fan belt slipping against the blower wheel. The best way to determine the cause of the buzzing noise is to remove the furnace cover and inspect the parts. If the parts look misaligned, try reseating them; if the parts appear to be secure, then it is time to call a professional for an inspection.


A clanging or banging noise is usually the result of a gas valve or gas-fired burner becoming stuck. These components should be serviced by a professional technician only, as servicing them incorrectly can be life-threatening.


Noisy furnace blower fans can cause a whirring noise which can be diagnosed by first checking the fan belt for proper tension. If the belt appears secure and not overly worn, the problem may be with the bearings in the motor, and a technician should be called.

Furnace Making Noise:

Preventive Action to Avoid Issues

PLEASE take preventive action in order to avoid any potential issues with Furnace making noise. Manufacturer recommendations and local appliance or HVAC technician's recommendations should be followed in order to prevent any potential issues.

HERE ARE SOME PREVENTATIVE MEASURES that should be taken in order to avoid any issues with Furnace making noise:

1. Change the Furnace Filter Regularly

The first and foremost preventive action to avoid Furnace making noise is to replace the furnace filter regularly. The filter helps to catch dust, debris, pet hair, dirt, and other airborne particles, which can clog the blower fan and lead to Furnace making noise. It is recommended to change the filter every 3-4 months.

2. Check the Fan Belt

The fan belt is responsible for driving the blower fan, which can become loose and cause the Furnace to make noise. To inspect it, please turn off the power to the Furnace and check the tension and alignment of the fan belt. If it looks worn or cracked, it needs to be replaced.

3. Check All Electrical Connections

Inspect the electrical connections of the motor to make sure they are firmly connected. If they are loose, replace them or call a qualified technician to do the job. Make sure all power is off when making any electrical connections.

4. Clean the Blower Fan

Furnaces can make noise due to debris or dust buildup on the blower fan. Cleaning the blower fan can help to prevent Furnace making noise. When cleaning the fan, make sure to turn off the power to the Furnace and take precautions to prevent electric shock.

5. Lubricate the Motor

It is recommended to lubricate the motor of the Furnace on a regular basis with a high-temperature lubricant. This will help to reduce wear and tear on the motor and reduce the risk of Furnace making noise.

By following these preventive measures, you can help to avoid any potential issues with Furnace making noise. If you have any questions or still hear any noises coming from your Furnace, it is best to call a qualified technician.
