YOu are describing either a sticky duovalve or an issue in the climate control module. PERIOD. That's it.
If the "mechanic" understood how the system works, he'd already have fixed it instead of talking about an "actuator" that does not exist.
A quick voltmeter check on the two outer pins of the duovalve will tell you if it is the duovalve or the climate control module.
