The most common product used by worldwide consumers, the ductless mini split, is highly efficient. In most circumstances it is likely cheaper to operate than geothermal because of lower installation and equipment costs. I think you’re onto something here. That consumers who need a temporary system sporadically or they need the cheapest possible system benefit from 1-hose. And if they need efficiency, air-air and geothermal are much more efficient.
2 hose is less convenient and more expensive, and marginally more efficient. It’s niche is apparently just not very deep. Window units are superior to 2 hose in every stat except the type of windows they work with and they are more visible from the outside of a building.
