Minimizing A/C use

Park in shade, windshield facing away from sun, use interior windshield cover when parked. Install heater core shutoff.

Otherwise, let HVAC -- on MAX Recirc -- cool car to knuckle freezing. Then adjust temp upwards and fan down. Not before.

The A/C "penalty" is negligible compared to advantages.

And

Dress appropriately.
