We live and sail around Pensacola, FL and we spent last August sweltering, and we swore then that we'd install an air conditioner this year. We've tried portable units, and have come to the conclusion that they are just too much hassel. I'm looking at a built-in unit mostly for the aft cabin, but I'm willing to do the whole boat. I'm looking for anyone who has some experience regarding brands, and instalation concerns. We have a 3.5kw genset right now, but plan to upgrade eventually. Any help would be appreciated.
