I have a single story 1700 sq. ft. home in New Orleans, La. My attic is insulated with spray foam insulation applied to the underside of the roof decking making my attic a semi-conditioned space (the hottest it got last summer was 82 degrees) i currently have a vertical unit and am looking to replace it with a horizontal unit. alright to the question can i cut a return in every room and just allow the air into the attic and put the main return in the attic so thay it will suck from every room?
just an off the wall idea
any thoughts are appreciated
