Ductless AC – Outside Wall?

Categories: A/C

Hi, I am researching ductless and mini-duct AC systems. One thing that I can’t seem to get a straight answer on is whether the indoor unit needs to be mounted on an outside-facing wall. In an attached brownstone, this could make things difficult.
Does anyone know whether this is true? Is there some part of the inside unit that needs to be vented outside? Thanks!
