There is a building
In uptown Lenoir, my hometown that was in the 40s thru the 80s Shields refrigeration and hardware, they were a Carrier dealer, anyway, still in that building and operating is one of those big consoles with a water tower, it is probably 7 feet tall and 4 feet wide, the compressor looks like a car engine!! and I think it uses Freon 500, if you stand in front of it it will make your teeth hurt!
