I wonder if anyone ever has two sets of coils (inside and outside) that they switch between seasonally? I'm thinking of places like northern Canada, where -40 is a common outside temperature for weeks at a time during winter, but 30 is common during summer (or even 40 in extreme cases). I imagine running costs dwarf the actual upfront cost of these units, but I don't know for sure.
Whether having the heat rejecting coils indoors or outdoors is most energy efficient depends on the local climate. It is a very straightforward calculation based on building heating and cooling requirements over a given year and doing such calculation (really more of consulting a table of pre-crunched numbers) is SOP in commercial refrigeration.
I assure you nobody with a commercial refrigeration need is pissing away thousands of dollars a year in energy by choosing the non-optimal equipment for their situation. Basically there is already a big "tax" on "doing it wrong".
