| I'm considering converting my AC to heat pump. This 1 story house had all of the duct work in the attic. It is on a slab so underfloor ducting is not an option.
I'm probably going to have to drop a return or 2 to floor level. For various reasons, I do not want any wall work done. Are ready to finish, or white, round ducts readily available to residential HVAC contractors? I do not think they'd have to be more than about 15" in diameter. I would put it in a room used for a utility/computer/work room so its appearance would not really be an issue. At worse I might have to cut a vent opening in the door to that room. Or just leave the door ajar.
Of course you see these all the time in commercial construction but I think they are uncommon in residential buildings.
