I've got a house in Phoenix with the original Goetle AC package unit

What do you pay in electric to cool for one year, 12 years ago we
junked a unit and saved 60% ever since, its paid itself back many
times over, like that 9mpg 350 Chevy Blazer I sold for a 20 mpg car, I
wasted so much money driving that gas hog, money ****ed down the
drain. You AC is inneficent , thats nothing to be proud of.

This may not be true for AZ. I have a friend out there that has an old
HVAC unit that also uses evaporative cooling. This takes care of most
of his needs. I doubt if any improvement in the compressor driven
section could signifiantly improve overall efficency of the system.
