In the interest of getting my office online quickly I have opted to use a 1980's window a/c unit.  I took it apart like I did the other 2 I have that are of 2000s build and saw the shame that is Chinese engineering.  Much more attention to detail in the U.S. engineered and built units.  While it is rated at the same cooling capacity of 12000 BTU I have run similarly rated A/C units in the same space and they do no where as well as this unit.  It is obvious there is specification inflation going on.

This unit must weigh at least 80 pounds and thus for a second story window mounting a support of some sort is required.  I built the deck you see in the following photos.  I designed it to be able to withstand aleast 2 joint failures so I do not have to worry about it falling.  In case you are wondering yes I had to satisfy my curiosity.  Before I place the AC unit on the deck I climbed up the ladder and hung from the deck dangling in the air to verify the support strength.

I used to have a similar unit. Mine had a gold front grille, black and gold controls, and pudh buttons that control the fan speed intead of a knob.

They probably stole your golden grill down in the hood :)

I have a simliar Amana window AC, purchased back in 1987…I beleive it's a 7800 BTH/Hr unit with a rotary compressor…I still use same every Summer up here in the N.E. U.S. Only thing I had to do to it was spray some contact cleaner into the thermostat a few years ago, other wise it works perfectly! :)

I am so happy to find this 1987 Amana article today because I own a 2006 Amana 17,000 BTU with heat pump made in San Antonio, TX USA unit that recently stopped working. I was going to replace it, but a friend offered to work on it for me, so he replaced the capacitor and it has been working like new since February 2022. Thank you for posting all of this information and other's comments regarding Amana a/c units. It gives me confidence to know that I probably will be keeping this unit for many more years to come. Mine weighs about 87 lbs, so I cannot take it out of the window by myself to clean it or do any work on it or I might have replaced the capacitor myself. Thank you for building confidence in Amana a/c owners like me.
