No A/C isn't much of an option in 110F+ Arizona summer temperatures.
TurboKraft overhauled a few 911/930 A/C systems recently.
In 1986-89 chassis, driving in stop-and-go traffic with 114F ambient temperatures, we were getting 30.4F from the center dash vents using R134a refrigerant.
* stock rotary A/C compressor (1984-89 style)
* stock front condenser, functioning blower (add inline fuse for safety)
* 964/993 condenser assembly in left front fender beneath headlight
* aftermarket serpentine evap core
* aftermarket serpentine rear condenser in wing -- customer had just replaced, but almost redundant because of the 964/993 condenser (have done other 930s w/o the rear condenser, still very cold)
* all new R134a-compatible lines, locally made
Not an inexpensive overhaul, but good for the next 20+ years of the vehicle's life.

And to replace the 2.5 gallon washer tank: we replace the factory RV/marine sized battery with a conventionally sized unit, and install a small fluid tank with integral pump. All the factory wiring and hoses are right there, so not difficult at all.
