I own a 350ft studio co-op unit which currently has an old AC unit and two electric baseboards for heat. I was thinking it would be nice if I had a single high hat in the middle of the room connected to ductless outdoor unit. This way I can put furniture where the ac and baseboard currently are. The problem is I don't think I'm allowed to mount anything outside.
What is the smallest unit anyone has ever come across? Any other ideas?
