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? (self.homeimprovement)

Looking for 10k-12k BTU.

I understand! So then given my limitation, a dual hose portable AC unit is my best option.

No question. We used a single hose one for years and it was way better than the window units in almost every sense (except for the above mentioned efficiency issue). Setup is simple, you can move/point it to a more desirable location, breakdown at the end of summer was simple, and ours was remote controlled (though this seems more common on window units too these days).

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!
