This is the land that time forgot with regard to air conditioners. Last year I saw a 1967 Ruud unit that was operating perfectly and a circa 1950s Carrier unit that was just fine. (The little old lady had service records for every year, going back to when it was installed.) I actually saw an old water cooled type last fall, from the early 50's (approximately). House was one of the old one's in the city without a meter. The owner (really old) always wondered why the water ran continuously all summer. Yeah, when was the avocado color scheme popular? I thought it was the 60's. Beige came in around the late 70's, or 80's. Turquoise ruled in the late 60's, early 70's, or so I recall. Nowadays, Taupe seems to rule. There should be a book....."Color Guide to Equipment Age". Every once in a while I run across a natural gas air conditioner. I know, a furnace is an air conditioner but I am refering to a cooling air conditioner, bascially a chiller. The ones I see are always in old condos. I guess I crashed your party Jim. Would you like a SweetWater pale ale from Atlanta?
