Consequently, what uses more gas AC or heat?

The air conditioning uses some engine power; it's been said about 10 to 20 horsepower. The heater gets its energy from waste engine heat that was going to be radiated away anyways, so it does come from gasoline but does not cost any more when run. So the A/C will use more gas; the heater almost none additional.
