A method for driving an actuator of an HVAC system is provided, and which comprises the steps of: a] determining an actuation command to the actuator; and b] ramping a drive power to the actuator between a steady-state-velocity drive power and a zero-velocity drive power to effect a required acceleration or deceleration to a movable member of the HAVC system without or substantially without over-powering of the actuator. An HVAC system is also provided. The HVAC system implementing the above method is not only capable of reducing the noise produced by an HVAC system, but is also capable of reducing an over-powering of the actuator when there is a low load on the system.
