    Normal for what?!

    See it all the time in mobile homes, just a grate in the door. Electric furnace.

    If YOU want change, YOU have to first change.

    If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!

    Seen in older houses. put sheet metal to close off space between wall studs. becomes a return to the basement and the furnace intake in the basement is open. I think 2 story requires balloon framing. Old term I think its correct.

    Let me clarify my question. Horizontal air handler was installed with a piece of ductboard covering return side and attached a 15" flex duct or watever size it required, but no plenum....

    If you see if all the times, that doesn't mean it was done correctly....

    Sounds like a lowest bidder job ,not enough money in it for a plenum

    You get for what you pay, never more, often less.

    Shorter is better

    but only enough to stop you from hearing the fan noise
    AND have transfer ducts for any spaces that have doors and don't "see" the return grill
    You have got to learn from other people's mistakes! Because God knows you don't live long enough to make them all yourself !!!!!!!!

    The only real problem with this is IF the blower or coil base partially blocks the return inlet in the bottom side of blower unit. This blockage could reduce air flow substantially.

    Pictures would be nice!!
