That is the same unit my Dad had in his bedroom.
So, I would say it's a 1972 1973.
Couldn't believe he left that in the house when he sold it and moved. It was brand new and only used one summer.
I had moved out and he built a new house with no A/C. We had 5 window units he left behind. 2 Fedders Weather Wheels 8,000 and 13,000, a 15,000 GE Super Thrust, His Chrysler Airtemp 6,500, and a 5,000 Westinghouse "Mobile Aire.
When all those units were running, it was like Antarctica in there.
Oh, Geez I almost forgot...a 8,000 Whirlpool in the Kitchen. It was a mid 60s model.
On a hot summer day or night, I used to walk around the house listening to the hum of the compressors and the sloshing of the condensate water splashing around.
They also had a distinctive odor like metal, heat and water.
Just like Bakelite, Rubber, Hot Water and Clorox in a Solid Tub Washer. Right ?
Gosh, things were made so well back then and really worked too. I miss those days.
Wasting Water, Electricity, and Increasing that Carbon Footprint too. Who the hell thought that one up... Carbon Footprint ?
