This is exactly what I am in the process of doing. 4'W x 4'H x 6'L, using a 5,000 BTU Air Conditioner and 1.5" foam board insulation. If I have my calculations right it should kick on for about 20 minutes 3 or 4 times a day during the hottest part of the Summer. Since I only do ales & ciders and my girls make root beer, I only need it to maintain 62F to 68F temps.
