Are there any window AC units that don't hang outside of the window (building requirement)? Or is a dual-hose portable AC unit my best option for an energy efficient AC unit? (sh.itjust.works)

Get one that is a heat pump and not just AC for more efficiency.

A heat pump isn't any more efficient than a AC only unit of the same SEER rating. They are literally the same system with the heat pump having a couple extra valves and parts to reverse the flow of the refrigerator.

That's true, though since it is a reversing refrigerant flow system, it can act as a high efficiency heater as well. The high efficiency heating+ multifunction of the unit ( which negates the need for a separate electric resistive or fuel heater) make it's overall performance more efficient in both energy use and spatial consumption, doesn't it? It's more efficient!
