Just switch on the A/C in Auto mode, set the recirculation to Auto as well and leave it alone. Messing with it and switching it on and off is what will knacker the compressor and seals not the temperature.

I'm not talking about pressing the A/C button on or off directly, just when you initially press the AUTO button. Say you turn off your climate control and turn it back on using the AUTO button...typically doing so in BMW's turns on the A/C (at least the A/C light anyway, even in sub zero weather) even if it wasn't on previously before the climate control was turned off, which is different to the behavior I'm seeing as described in my post.
