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. http://www.gcsu.edu/mansion/ -- *Michelle Zupan* Curator Hickory Hill & the Tom Watson Birthplace 502 Hickory Hill Drive Thomson, GA 30824 706-595-7777 FAX: 706-595-7177 Visit us at www.hickory-hill.org or on Facebook <https://www.facebook.com/hickoryhillmuseum>.
