I'm looking to finish our basement. I've got a lot of issues with Ducting and plumbing, but my head scratchers are with the forced air ducts. I've been blessed with a sunken living room which gives me very little room to move things around. The sunken room gives me only 6'2" which in some areas I bet I couldn't get permits to finish but i digress...
I do have a 'hallway' type area. Without cutting structural beams the clearance in this area is greater at 7'2". Issue here is that the air ducting is taking 10" of that area plus the space in between the duct and the floor beams. This brings the ducking to the same high of the sunken living room of 6'2".
Any ideas on how I could reroute the piping?
Can I change that Ducting of 10"(H) x 20"(W) to a 6.25" x 32" rectangle and still get the same CFM? This could give me enough reasonable head space.
Also, can the duct be closer to the wood? the gap is sagnificant but I would'nt want to compermise safety.
