Blower Wheels

Blower wheels are a part in your air handler or furnace that circulates the air through your HVAC equipment and in turn, through your home.  They come in two types - belt drive and direct drive.  Belt driven have the motor mounts on the outside of the housing and direct drive will be mounted inside the housing. You can typically determine which you have by making a visual assessment.

Blowers consist of 3 parts:

• Blower Motors - This is the motor which powers the blower wheel
• Blower Wheels - The fan that rotates and is sometimes referred to as the "squirrel cage"
• Blower Housing - The frame which surrounds the blower motor and wheels

Blower wheels are usually not difficult for most consumers to replace, but as with most HVAC equipment, it is considered best to have a professional make repairs.
