on some cars (like my civic 98 and crv 98) it doesn't matter.
what matters is kung on or off yung aircon. the temperature setting does not matter. the level only controls how much hot air from the engine is mixed with the cold air from the evaporator in order to set how hot/cold the cabin temperature will be. the time the aircon compressor is turned on/off is still constant regardless of the temperature setting.
i just set it kung saan ako comfortable.
got this info from the experts at another forum (specific for my car) and from mang mario himself.
on other cars, hindi ko alam
