An air conditioner does create more heat than it cools. It releases the heat of the electricity or mechanical work plus the heat it removes from the cool side.
Unfortunately trying to recover energy from the heat released is not easy or significant because of the low temperature differentials you have to work with.
To summarize the first, second, and third laws of thermal dynamics: You can't win. You can't Break even. You can't get out of the game.
