    r/a blocked by dresser

    in kids room of house where I am going to work tomorrow
    there is the heating closet in the hall with a r/a below
    in the kids room..around the corner is another r/a.

    the room has twin beds, a desk & a dresser. doesn't seem to
    be a way to arrange the room and not block r/a.

    if I put something in the floor moldings to hold the dresser
    (or whatever they put by the return) out from the wall
    about 4-5" will that allow sufficient r/a to the r/a in this room??
    will 4-5" suffice??
    if not...what distance will allow r/a back to grill??

    You can search for an online duct calculator and plug in your own numbers. I found one and plugged in some assumptions and came up with the following: Assuming a 5 ton system with two equal return grills accepting 1000 cfm each. Assuming the dresser is 36" tall and out from the wall 6". The calculator states that 6" x 36" @ 1000 cfm = 667 fpm. 667 fpm is less than the max of 700 fpm across the return grill. I think you will be ok, but other members may want to chime in with a better answer.
