One system, two seasonal jobs
In cooling mode, heat is moved out of the room; in heating mode, the system moves heat into it from outside. This is why an air-to-air heat pump is also described as heating and cooling air conditioning. Reverse cycle air conditioning describes that change of direction, rather than a separate kind of installation. The practical question for a homeowner is where that flexibility would help: a home office used throughout the day, an extension or a loft room with different comfort needs from the rest of the house.
