  That’s not what central air conditioning means. Central air conditioning has forced air ducts and a single chiller unit. This is called a mini-split or split unit system.

    It is in fact literally the opposite of central, aka decentral

  I consider these superior to central air due to its ability for zone control.

    That would depend on just how many zones you want to control. If you have multiple rooms then you will need multiple mini splits. That adds up real fast. And multiple minis are more expensive to operate and maintain than one central HVAC system. Plus doors can be closed and duct vents can be adjusted easily.

  Got you, a fancy cold-blowy box :)

  I think I’ve seen one of those once in an office somewhere - though I feel like that one blew out warm air instead/as well (I may be mistaken).

    Fun fact about air conditioning units. They are basically a glorified heat pump. And many of the newer units that are being produced can pump heat into the house as well as pumping it out of the house.

      That’s not just a fun fact - it’s a useful fact :)
