Ok so we are building a double storey house with 5 points UPSTAIRS only. The back of our house drops to a singe storey to the living area.
I have a plan to re-locate one of the evap air ducts (the one in hallway upstairs) to down stairs in the single storey living area section. Is it as simple as attaching a longer duct, using duct tape and re locating the duct in the ceiling down stairs?
I know there is room/void/access and I know the right path behind the plaster/studs/trusses
