I am trying to understand ductwork sizing as it relates to residential AC. I have read Manual D cover to cover but sections 3 and 4 make no sense to me, I just donít get it, call me stupid but those sections are very hard to understand the way itís is written.
Are there any suggestions for other written material that explains those two areas? Thanks
