Water-source heat pumps are a decent middle ground though, as the compressor is in-unit and connected to that unit's electricity. Central chillers/boilers with a 4-pipe system (e.g. Charlie West) results in each unit only paying for the fan for the fan coil unit, so heat/AC is basically completely covered by condo fees.
The same is true for the two-pipe system: the air handler pushes the air over the cooling/heating elements (cooling or heating for those is provided centrally). The difference is that a two-pipe system can only provide either heating or cooling at any one time, not both: the building needs to switch between the two modes each spring and fall (each switchover takes a few days at a minimum).
