Yep, you get what you pay for. They've started fielding systems that will handle extremes much better, but you dont get that kind of performance without tradeoffs. cascade systems, 200psi r600, 450psi CO2, refrigeration systems are an engineering game irl. They require much more experience to design, setup, and charge correctly. The biggest issue I have with heat pumps for life support heating/cooling, is they have so many single points of failure its scary. Compressors can and will die if anything else in the system goes too far out of the intended cycle. Extreme weather moments or natural disasters can physically break condensors, evaporators, and lines. Electrical surges can and will fry computers, inverters, and controllers. And almost none of those can be serviced on your own.
