To add:

A properly working (read - airflow through the condenser coils and a properly charged and oiled system) R134a system will reduce the ambient air temp about 30 degrees at the air vent.

If you live in an arid and dry area like Arizona, there are many times where the outside ambient air temp is lower than the inside cabin air temp. (Example - when the outside ambient air temp is 110 degrees F, my inside cabin air temp can he as high as 130, according to the little thermometer clipped to my air vent. This is when my truck is outside in the sun for at least 3 hours in the afternoon)

In situations like this, running on recirculate actually ends up being less efficient than running on a non-recirc setting....hence the joke about Arizona residents finally getting cold air out of their A/C when they get to their destination.

A Spal or Flex-A-Lite fan will do wonders. I have a Spal add on fan for my A/C condenser and I get cold air all the time - even when I'm stuck in traffic.
