While a realize a question of motives might be a bit of a stretch for
this list, I am kind of curious for a brief take on why you do not
plan on using refrigerant.

I live in TX too, and I sure as heck plan on having A/C in my car, but
in my car, the plan is to just use the refrigerant that is already in
the car, and just hook an electric motor to run the compressor.  (Even
if I didn't use the refrigerant, I would still have to dispose of it.)
 This method is less efficient, but it is cheaper and easier.
