When should I decide on the AC system?
At the concrete (structure) stage. That's when sleeves, duct routes and drain lines are left in place; doing it after tiling and paint costs much more.
Which is cheaper to run?
Running cost depends more on insulation, sizing and use than on system type. VRF can save energy in homes where only some zones are used at a time.
