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!
I understand! So then given my limitation, a dual hose portable AC unit is my best option.
Get one that is a heat pump and not just AC for more efficiency.
