My air con installation was on schedule. After much consideration and some advices from the air con man, i decided to install the air con above the window in my master bedroom.. hope it’s not a bad decision after all. 🙂 As for the common bedroom, i let the air con man decide where to put it, since i have no plan on where to place my furniture yet. As far as possible, the common rule is not to let the air con blow directly towards us, and hence definitely not directly above the bed nor directly opposite the bed. Another concern is to have the trunking as less visible as possible.
