    Default AC Return

    My 2nd flr unit does not cool as I expect How do I know if I have adequate return

    In my daughters room there are 3 supply lines and no return you can feel lots
    of air from under her door and pressure when you open it

    I am thinking I am not getting enough return air, I am leaving her door open to see if it helps,


    any way to tell?

    If the supply pressurizes the room, you need to supply a return path. If you can duct it all the way back, you could put a pair of registers in the wall to get it back into the hallway where it may find its way back to the existing return, where ever it is.
