    They still make those old style ones and they are energy star certified.

    The ones that look like the new one are what’s used with heat pumps here.

      Is there any reason a window unit couldn’t be a heat pump? My understanding is the difference is just about a single valve to reverse the direction of the coolant.

        I thought it was just that it was too difficult to fit all the parts efficiently in such a small box

        When Tesla first publicized 3d printing the “octovalve” as a piece to complex to manufacture traditionally, the claim was that it made the heat pump much more compact. There was even a rumor going around that they might use it to enter the home heat pump market. Their work in making heat pumps compact enough for cars could really make a difference, however I image home stuff is much more price sensitive

        From my understanding is a heat pump needs to be fully outside of the house.
