We tried one in the south and it was a pretty horrible experience, because of our high humidity in the cold.
The outside unit constantly froze up, which even ideally requires a defrost cycle (wasting energy pumping heat back outside), or worse, uses heating element outside just to make operable.
While those cycles run, heat couldn't. Except that even emergency heat (heating element inside) would disable the outside defrost, supposedly to meet EPA set energy budget, not technology limits.
That's not the kind of BS you want to put up with on frozen nights, whether from a technology or policy standpoint.
