Interesting AC story
My Uncle, who is a retired electrical contractor, and Earl Shell, a friend who got a degree from the Carrier company, MADE a central AC unit in 1958 for my Aunt and Uncles 1956 ranch house, they took a Lennox 2 ton portable AC unit...a real contraption from the early 50s, it was on wheels and used a sealed water condenser, anyway, they took it apart, built a shelf above the oil burner of the Armstrong furnace, mounted the compressor on springs, Earl piped the whole thing up, it was used like this till about 65, water got expensive so a outside condenser was added doing away wit the water condenser, they moved in 76 and the people who bought the house used it into the mid 90s! I can still remember how nice that COOL house was! As a kid I thought that was really something as most people had window units then.
