Blower Motor

What is a blower motor?

A blower motor is a component of an HVAC system that operates a fan or blower wheel. It works off of a thermostat that signals it when to come on. The fan then blows the air to the heat exchanger or evaporator coil and then through ductwork throughout the home. This provides for even and efficient heating or cooling.

Where is it located?

The blower motor is located in the HVAC air handler near the air filter.

Maintenance Tips

  • Change filters every 3 months
  • Lubricate motor bearings annually
  • Tighten or replace motor mounts every year annually
  • Clean blower blades with mild detergent annually
  • Inspect electrical connections annually

    • Lifespan

    The lifespan of the blower motor is about 15 years.
