      Except it is not 100% efficient. It will have losses, which will add extra heat to the surrounding area over what was removed from the target area. Thus contributing to the increase of entropy in the universe. And bringing us one step closer to the heat death.

      ACs also generate heat as a waste product (they’re not 100% efficient), but I’m not sure that actually heats up the surrounding area to a noticeable degree.

      Yes your right should have been more clear. If AC moves hot air from a house. This hot air goes out then imagine hundreds of AC doing that. Would that in turn heat up the area around it.

        To be extra clear: An AC transports the heat, not the hot air. It removes heat from the air and transfers that heat to the outside air.

        There’s also heat pumps that work with water instead of air. So they remove heat from the air and push it into water. This water can be a closed loop, or be open where the water is lost. It can also work the other way around where the heat pump takes heat from outside and pumps it into water, heating up the water to then be used for heating a home or taking a shower. There are also water-water pumps that work on water on both ends.

        Because heat pumps pump the actual thermal energy, the medium doesn’t really matter much.
