Yes, but as it is cool inside the system, when you turn off the car, the cool interior surface of the air con assembly draws in moisture, which sits for quite a while and a perfect environment to harbour mould/mildew. If you turn off the a/c a few mins before stopping the car (but not the total system) then the warmer air helps bring up the system to outside air temperature so when the car is turned off, moisture won't accumulate on the interior surface of all the aircon system.
