People that live in dry heat ditch compressors and freon, period.
Whatever it takes, you must use evaporative cooling. It isn't simple. it isn't cheap but copy what the gambling halls used to do in Vegas for RV customers.
A four-foot cube of evaporative (swamp) cooler will OUTcool three roof A/C units, This is not an exaggeration, been there, done that in the Antelope Valley in California where the nearest shade was miles away.
Swamp coolers require 120-volt power and perhaps 50 - 80 gallons a day of water,
Mine was on the roof but a side exhaust will blow in an open window. The air exhausts through similarly open windows at the other end of the rig. This means the air must blow through the full length of the rig.
A carpenter can build the platform. Foam rubber seals the unit against the open window. I made a skirt of astroturf for the platform.
While out of doors approached 115F inside the temp was 72F to 75F. The blast of incoming air was too chilly for me to stand (under).
In Michoacan, I am stuck using refrigeration because the humidity is above 40%.
It's interesting to note when starting an A/C how the humidity must fall to 60% before temps start to drop.
