My 993 AC is always on, just like my Audi and my wifes Lexus. The CCU takes care of it as any other modern car. It is designed to work that way. Check your manuals.
Turning the AC off before shutting down and starting it after the car is started comes from the old days of manual AC units to take the load off the compressor while starting and to avoid damage to the solenoid. With climate control units, there is no need for that anymore.

a/c
I'd like the option of being able to turn the a / c off and just bring in cool outside air with the fan. On our other cars, (VW, Audi, Subaru) there is an override. But this is a minor nit.

I've been on the board for six years, and I don't ever recall this question being asked. Kudos to you for doing a search and for asking what appears to be a new question! I had no idea that so many people practice turning off all electrical devices before shutting the car down.

I turn everything off at shutdown, both in the 993 and in the redneckmobile. I forgot once, and the A/C in the 993 kind of "lurched" back on when I cranked up the car, almost as if the blower started up before the vent flap opened or something.

I have a switch on my 993 that turns EVERYTHING off before I exit the car. My other cars have a similar switch, but they are all on the right side of the steering column - the 993's is on the left.....
