question on a/c operation

[miflox]

Something has been bugging me lately here in hot, humid south florida. I usually just leave the a/c on and the fan button on all the time. So, when I start up the car, the a/c and fan starts blowing cold air pretty quickly (which is damn good for a '98- hopefully, the elderly couple that had it before me had any problems with it and got it fixed). Anyhow the question is:
1)When you pull into the garage or go to the mall or someplace for a few hours; do you shut off the a/c blower motor fan and then start engine and push in a/c blower fan button? Or do you just leave everything on all the time?
2) I'm wondering if it's any good for the engine or a/c system to start a cold engine in the morning or after 4 hours or so and immediately put a load on both the motor and the a/c system.
Thanks for any comments/advice.

I don't worry about the fan as it's electric but I do try to remember to turn off the A/C button (or fan to off) before starting the car. I could be wrong but I think it's better to have the engine started before kicking in the compressor.

The A/C compressor clutch is de-energized like your headlights, radio , etc when you start up the car.

Thanks for the tips. Will turn the fan to off now when parking. Turn on after 5 seconds or so.
