Welcome Lin and L3x, yup, me in 181 facing the market...very near to food...kekeke i am also thinking of putting 1 aircon unit in the living room. i did some calculation and Kingzkong is right, 22k btu is more than enough. Area x 337 = the btu needed to cool the room. but how often will i turn it on is 1 qn haggling my mind...dun install, if i need it and don't have, how? From 1 of the movie: rather have a gun and don't need it, than not having a gun when u need it
