I just moved into a new house and all of the A/C vents are facing the adjacent wall instead of blowing in the middle of the room. Is this an error or do you want the vents to face the wall?
I blow mine toward exterior wall, door or window ,let the return suck it back across the room.
Sounds like they are in backwards.Hard to imagine ,that anyone could do it,but I have seen it once.
Probably shouldn't say this,but it's scary to think what others mistakes were made,hopefuly none.
