Hey guys! Quick question. I'm a refrig. mecanic so do have some knowledge.
1400ft2 upstairs and downstairs. Return air in master closet up, using round duct and barely pulls air.
Return air down using 2 joists and closer to indoor unit than the return i'm concerned about upstairs.
Return upstairs is in great room of 1000-1200ft2 with 9-12' ceiling. In a/c it seems to take a long time to condition that huge room, i'm sure partly because more air is being returned by the cooler space downstairs and closer to furnace,
Anyway, if i cut another return in the same double stud cavity upstairs, in the great room, at ceiling height, will i pull MORE air out of that room, even though the duct size hasn't changed?
I'm aware i will pull warmer air as it will be higher up, but what about MORE air?
