To answer a question about where to locate an A/C unit on the H37C here is what I did. Others can tack on with their installs. I don't think there was ever a factory install but someone may have other information.
As seen in the pictures I installed mine as Paul suggests, in the quarterberth cabinet. This is a 12K Mermaid but I sized a 16K and it will fit. I wasn't willing to give up storage space for ducts so it just blows into the main cabin under the nav table.
The pump and intake filter are located in the aft bilge section. I installed a T-valve on the engine water seacock so that I didn't have to put another hole in the bottom. This has worked well for fifteen years. When I had the boat in Florida I could definitely have used 16K. Here on Lake Erie the 12K is adequate.
