thanks Zappa : so the 6 in the basement and the 6 in the 1st floor are supply ducts (not return) so do i just need 6 in basement or do i need 12 on all supply ducts ?
I would think two unless you only have one supply trunk feeding both floors. I was thinking that you had two trunks but that might not be the case. Zoning can be complex and you have to consider bypass air when only one zone is flowing to keep the heat/ac equipment happy.
