This air conditioner of hitachi is good for even large rooms.ours was a large size bedroom.but it proved very useful for us.it cools the room amazingly.and its main feature is that it has many advance options which can be adjusted according to requirement.the only con of this ac is that it doesnt provide free services otherwise it is a great one to go for.being a japanese company hitachi proved itself withthis AC for us.thank you hitachi.
