With the recirc on you are trying to cool that very hot air, and it will take a lot longer for the interior to cool down. Instead, use outside air for the first few minutes, then switch to recirculation. Living as I do on the surface of the sun, tricks like this really help.

I agree. I hardly ever use recirculation anyway, unless I'm driving behind a smoking, smelly car.

If the windshield is fogged up, I choose the defroster setting until the window has cleared.
Furthermore, I almost always use the automatic setting of the HVAC. In almost all cases the system chooses the correct settings. It takes into account the inside, outside and set temperature and chooses which ventilation openings itself.
Only for the last five to ten minutes of a trip do I turn off the AC to let the evaporator dry to prevent mold.
The automatic HVAC is quite well designed and smarter than most CX-5 owners realize.
