Bob, my home is 1910 vintage masonry & stucco.
Very sound built by an architect & stayed in his family until we purchased. Problem being in a beach community with modern asphalt & concrete this house is no longer breeze efficient. We need central air! problem 2, We do not have sufficient
space for the main trunk & several years ago still living in N.Y.C. i saw a show (maybe yours) about a relatively new system that cooled as well as heated thru pvc tubes showing only a 5" rosette on the floor or the wall. every one i call beleives in modern technology but still think i'm daff. HELP!!!
