The Old Governor's Mansion in Milledgeville, GA underwent a massive restoration and had to install new HVAC. They did some really wonderful things in how they installed the furnace, etc into the attic and then hid the vents in the crown molding. Matthew Davis is the Director and has been there through the entire process. He can send photos.
