I can see lots of owners in Phoenix complaining the AC doesn't feel as cold and people in Montana saying the heater stinks. Maybe they have gotten much better with them, but then I have to ask, why aren't they more common in new construction homes in those areas? Seems like they are a more mild climate solution to heating and cooling.

Heat pumps are more efficient because they use the phase change of a gas to move heat.
I switched my current house from a natural gas furnace to a heat pump. Super efficient and rated down to -10F and it doesn't have a back-up resistance heater. We've had no problems so far in 6 years. It worked fine when we hit temperatures of 115F this year.
Our other houses had older style heat pumps with resistant heater backups for temperatures below freezing.
