I bought a new home (new construction) last year. At the time, we opted to have the "rough-in" for future air conditining done, but wanted to wait to finish and add the condensers until we could afford it better. We are now about to do that. The heat in the house is all baseboard. I just noticed for the first time that the builder added all the duct work and vents on the first floor and in the unfinished "bonus room" over the garage, but their are not any vents in the second floor bedrooms. When we asked the builder, they indicated that they do not normally do that as part of a rough-in, the final ductwork in the attic and the 2nd floor vents would be added during the final install. Does this make sense or did I get short-changed by the builder on the rough-in?
