Well AC is a power drain, but perhaps it is due to extra drag from having your windows open when not using AC?

Or, if your car has Auto climate control, it is possible the AC is cycling more than you realize in auto mode...

Or you drive it differently when you have a cool head...

Can't think of another reason, AC isn't free, the compressor robs power from the engine to provide cooling breezes, so that makes the engine consume more gas, all other things being equal
