Ideally, you'll want to run the fan full blast before the A/C is used at all, but the controls are designed such that having the A/C on with the fan on full blast gives you a lot more A/C than you need and wastes a lot of energy. So how about modify the controls to allow less A/C. Maybe a PIC or Arduino sensing factors like supply register temperature, engine load, brake lights, etc. and controlling the compressor automatically.
