Well, I am a partial perfectionist when it comes to certain things, and I dont think my car blows out air cold enough..... Our suburban (albiet brand new) will FREEZE you..... And I am going to assume that nothing has been done.... I am all part of the extremes... and when I get into the hot Q (my Q gets hotter inside than any other car ive been in, including our black on black 02 GTP), I want this baby to just FREEZE me..... It takes about 1-2mins for it to start getting cold, and then a few more for it to start cooling things down......
Would the most common area of fixing be the drier.....? I am going to have quite a few things done when I get my shocks replaced next month, so I can have them check it then....
Insuffecient AC.....

From sitting in the sun to 46-50F may take 10-15 minutes [at 60 mph] depending on color and local solar radiation to reach equalibrium.
It starts out around 125F [105-140F]...............wow only 45 seconds to feel cool mine takes 2-3 minutes to produce 80F but it takes me 5 minutes [2 spot signs and 2 red lights to get on the expressway].
There is only so much cooling that 30,000 BTU/hr [500 BTU/min] can create. the compressor rpm [pullet ratio] is set for 2,000 engine rpm] to increase compressor life.
Many domestics who don't care about 200,000 mile life use a differing ratio so the cooling comes earlier.[but not much say 10-25%]........kind of a function of 36k vs 60k warranty.
Pretty much all AC systems are created [designed equal] for equal interior volume cars.
With R134a system the pressure errors are more critical [vs R12] a 10% over or undercharge [2/10ths of a pound] will show up as a 7-10% too high center vent temperature [3.5-5F] when coupled with dirty fins on evap or condenser.
