I'm interested in getting two split-system a/c units for my apartment (I
own the building). One at each end.
All the systems I've seen involve a compressor that sits on the ground
outside the building, but I feel like I've seen split systems that hang
like a window unit.
I'd rather have something that is mounted up on the exterior wall than
down on the ground (outdoor space is precious in NYC). Is there such a
thing? Are there any issues with mounting it? I have brick exterior,
covered with concrete on the rear wall, but uncovered on the front.
I don't require more power than available window units, I just don't
want to have ugly a/c units in my windows.
