Types of AC Motors

Your AC system has two types motors found in either the indoor unit (evaporator) or outdoor unit (condenser) that are crucial to your systems functionality: blower motors and fan motors.

What is a blower motor?

In HVAC, the blower motor is responsible for driving the fan in your inside unit that circulates air over your evaporator coil and throughout the ductwork andvents in your house. There are primarily two kinds of blower motor that are used: single-speed and variable-speed. A single-speed motor operates at one speed and will shut off once the thermostat temperature is reached. A variable-speed motor can operate at a range of different speeds and are generally more energy efficient than a single-speed motor.

What is a fan motor?

A smoke or burning smell coming from the vents in your house.
Your energy bills are abnormally high, a malfunctioning motor can cause the system to work harder.
