It will definitely affect the air outlet, and if the ceiling is to remain unchanged, the length of the air outlet can be increased.

Chinese architecture generally pays attention to symmetry, in fact, without the design of the return air box, the air conditioning inlet and outlet can not be in a line, because the air above the ceiling is connected, as long as there is a return air, but the air outlet generally needs to be facing the air conditioning outlet.

There is a little, but as long as the design and installation are good, there is no big problem.
