"back in the day", many would say a/c used up 1 to 2 mpg. then tests wre done and it was concluded that driving with windows down used more mpg do to drag on the car. never read a study, this all here say from "old motor heads from the sixties. i am sure turning the compressor uses a little mpg. i don't see how heat would.
