My engine is so gutless that I can "feel" the load of the AC if it is on and from what I can tell it loads the engine just about as much no matter what setting I have it on. Turing it off while accelerating is like a mini-nitor boost! As a result, I cycle it on only going down hill or decelerating since I have a little energy to spare then. It blows cold for a good 20 seconds after I shut it off.

Also you should never come to a stop (arrive at your destination) with the AC switched on for two reason:
1. It's a waste of energy since it will blow cold for a while after you switch it off and number 2, even important to non-ecomodders, the wet cooling system will take much time time dry this way and smell of dank mildew over time... even in new cars but especially in older cars with some dust inside the vents. Do yourself a favor and switch it off (but leave the fan running) about 60 seconds before you park.

On a side note, it never occurred to me to run re-circulate in hot weather! lol. I used it all the time in the cold in Oregon but I an new to driving in the heat. Thanks all for the tip!
