Unit manufacturer can provide you IEER, SEER and EER ratings.
But you are trying to compare apples and oranges.

VRF is much more complicated and if something fails, the fix can be expensive. Whereas with window units, you just go to your local hardware store and buy a new one.

Another consideration with VRF is the amount of refrigerant you now have. Be sure to check ASHRAE 15 for design/installation guidance to minimize risk to your occupants.
