Is 18x8 enough for 2 ton, 800CFM system?
Im asking this because there is several different duct size charts and they dont tell the same. For example one lists 18x8 for a max of 700CFM while the other one does for 800CFM.
Some recommends 16x10 as the way to go..
I would love to use 16x10, however, its hard to fit it in the basement installs...
