Hi Danny, welcome to the 166 forum.
My apartment had air conditioning already installed when I bought it. I believe the main a/c unit is on the roof, as my apartment is closer to the roof than basement.
There are a collection of a/c units near the garbage bin area in the rear car park. These probably service lower level apartments.
So depending on your proximity to the roof or basement level, will determine where a unit could be installed.
Hope the helps
John
