If you are considering ducted reverse cycle, serious consideration needs to be given to;

-The brand and rated power of the compressor unit
-Refrigerant capacity
-Power source (Single or Three Phase)
-Motor control type (Inverter,Digital or Analogue)
-The size of the area to be climate controlled
-Your budget and tolerance to running costs

All in all, depending on your specific climate, reverse cycle can be the master of trades, but only if it is a robust and very well engineered system. Cutting corners for smaller units and expecting a whole house to be cooled off a single split is just asking for trouble.

Evaps also have a significant role to play where lower running costs are needed, however it should be noted that on a 40 degree ambient day, an Evap may be able to cool to 25 degrees, where an equally strong Reverse Cycle may be able to pull the temperature to 21 or 22 degrees also whilst drying the air. However you have to pay to play in that regard.

All the best mate, but really consider how you intend to use whichever system you choose.
