The interesting engineering in a modern HVAC system is not the refrigeration cycle — it is everything wrapped around it: the staging of the compressor, the communicating thermostat, the ductwork that quietly throttles the whole thing, and the topology choice between a furnace-and-AC split, a heat pump, and a ductless mini-split.
