Concrete example while we’re on the AC unit debate—there’s a very simple way to increase efficiency of portable AC units, and it’s to wrap the hot exhaust hose with insulating duct wrap so that less of the heat on that very hot hose radiates directly back into the room you’re trying to cool. Why do companies not sell their units with that wrap? Probably for one of any of the following reasons—A.) takes up a lot of space, B.) requires a time investment to apply to the unit which would dissuade buyers who think they can’t handle that complexity, C.) would cost more money to sell and no longer be profitable at the market’s price point, D.) has to be applied once the AC unit is in place, and generally is thick enough that the unit is no longer “portable” which during market testing was viewed as a negative by a large % of surveyed people, or E.) some other equally trivial sounding reason that nonetheless means it’s more cost effective for companies to NOT sell insulating duct wrap in the same box as the portable AC unit.
