What do you think of A/C system?

I disagree. I've owned several R12 cars and they all had very good A/C output. When the switch first occured, manufacturers had to scramble to redesign the various A/C components to be more efficient because the R12 refrigerant is inherently superior to R134a. So some of the very early R134a systems were not up to par with the older R12 systems they replaced. Further complicating the issue is the fact that a lot of guys retrofitted R12 systems with R134a when R12 started to become hard to find or expensive to buy. These old R12 systems were not designed to work well with R134a, so perfomance suffered, although it did work.
But as time passed, manufacturers started changing evaporated sizes, condensor sizes (and designs) and even started changing the pressures. Today's average R134a system is every bit as good as the average R12 system from years ago. This has been proven by measuring the A/C duct outlet temps of newer cars at various ambient temperatures and comparing the readings with the older R12 systems.
BTW, R134a is on its way out very soon, to be replaced with another more "greenhouse" friendly gas. If you remember, the problem with R12 is that it depleted the ozone layer. Well, R134a does not deplete the ozone layer, but it is known to be a greenhouse effect gas. But don't blame this next change on anyone but the Europeans. They are the ones who decided to phase out R134a, which will cause us to have to deal with another change to our vehicle's A/C systems. BTW, I learned all of this in a trade magazine and you can definitely count on this happening, probably by the 2011 model year or somewhere right around there.

By the way, I forgot to say this:
Yes, we did land on the moon.
Yes, R12 does deplete the ozone layer
No, New York is not a communist state
No, the U.S. government was not behind 9/11/01
This is in repsonse to a few of the anti-NY posts you've made. I'm a lifelong New Yorker (born & raised) and I'd like to remind you that this is the USA and you have the freedom to move to any state you choose. Be happy, not Annoyed because life's too short!

I'm 54 and had over a dozen cars - the majority used R-12.
The A/C in my 2007 V-6 is just fine. Definitely does a much better job than what my Subaru Forester managed. Also better than the Dodge before it or the Nissan before that. I can only say good things about the Toyota A/C.

When I took delivery of my 2008 T4R in May 2008, I thought there was something wrong with the AC because it was so dang cold. I had to turn it up to 75 during the summer otherwise it would freeze me out of the truck. Over time it seems to have adjusted itself and now I keep it at 70-72 and it's very comfortable.
I kept the temp on 68 in my old 2006 T4R during the summer to keep the truck cool.

I'm sitting in my car right now w/ ac on low, the thermometer says its 84 outside. The air at the vent is cool at that. I just replaced the filter so its not that. I honestly think this ac is a pos.

You should get a thermometer and measure the outlet temperature. The easiest to use are those infrared thermometers that give you an instant temp reading by aiming the laser light at the vent.
Of course the outlet temp will vary with different ambient temps, so you can look up your particular readings on a chart to see if they are in acceptable range.
We already had a near-100 degree day here and I was dressed in a long sleeve shirt and pants at work. My 4Runner was baking out in the sun all day, so it was hot as hell inside. I started it up and turn the A/C to Max. Within about 10 minutes of driving, it was uncomfortably cold, so I had to turn the temperature up to 70 degrees. I'm 100% satisfied my the A/C performance in my 4Runner. It seems to work just as well as my other vehicles, so no complaints here...

Just below the ignition switch there is an inlet where cabin air is sucked in and it's temperature is sampled. My A/C was so weak when I got my 4Runner that I was going to take it in for diagnosis. Then one day when I had that area of the dash apart I needed to disconnect the sampling tube and happened to look inside it. It was packed with dust(and I mean solid!). After vacuuming it all out I tried the A/C to see if there was any change and the air out of the vents was now really cold. I recommend checking this out if your A/C is not cold. It saved me some bucks.

That would only affect that "auto" control. Manually have the fan on high and temp on low should not be affected by that. The tube is for the auto sensor to determine the ambient temp inside the cabin then adjust the fan/temp accordingly.

Kind of unusual question but do you drive home in the sun or is the sun behind you.
