The only data point I have is that I got a quote last year for installing ac in a Bristol 41 and it was 16k. I don't know how size affects that price but I would think the unit could be smaller for your boat. I did not get a breakdown of parts vs labor. I ultimately did not buy the Bristal and bought a boat that already had heat/ac installed. There are hatch mounted units that seem to work quite well and are considerably less expensive. You have to stow it somewhere though when not in use. Good luck.
