I've heard tales that the factory did not open the hole from the AC to the duct. That should be easy enough to check by dropping the AC cover (inside) & reaching, probing the holes out the side to the cieling ducts. You should have received documentation on the AC unit which will show what I'm referring to.
Apparently, in some units in their product line, the air only comes "straight down" & the holes for access remain plugged. Then I understand that maybe an installer forgets to remove the cover............
I'm only relaying 3rd hand information though.
