Condensorless AC available in the US?
We have an upcoming installation where the customer does not want a unit outdoors - it's a landmarked building in NYC.
An online search found POWRMATIC which requires only two access holes through the wall and no outdoor unit. Seems to be available in the UK only.
This is for ac only - although supplemental heat would be OK. Split uit with 2-4 zones would be optimal.
Does anyone have any suggestions?
