Its pretty cold, not that cold but an okay A/C unit in the car.

Ive seen worse...ever been in a Diablo?

Thats not how an HVAC system works buddy in a simple sense, the hotter outside it becomes the less efficient it becomes, it becomes harder for the condenser to transfer the heat of the cabin into the outside environment. The air coming out of the vents should be at minimum 20 degrees cooler than the outside air if running at maximum setting.

My AC unit blows colder than any other car I've had, so if yours does not seem cold, I'd check it out.

Actually I do know how they work.. Poor choice of words on my part.. My point was that you "feel" the temp difference easier when the ambient temps are higher outside. Without going into too much detail..
Like running the AC on a cold day.. You might not realize how cold the AC is actually blowing.. Not to get too complicated.. The OP did say it was just warming up outside.. As in not too warm yet..

My point was that the temp difference is more noticeable when its hot outside.. My bad using the word efficient..

Depending upon what you're comparing, it might feel warm. R134a is much less efficient than R12; pretty much all cars I've driven post-'94 (when R134a became mandatory) only blow cool when moving. At a stop, the exchanger can't reject the heat.

Having said that, IMO the system in these cars works pretty well.

I rarely run the A/C I discovered if you turn on the air, blow it on the windows, have it set to circulate in the car, it actually cools very well inside the car in 90 degree weather, with no power loss. :P

does it blow colder when u start driving?

turn car on, put AC on, pop hood and check the radiator fans. One of them has to be working. If none working, there is a chance that a fuse blew.
I had this issue after heavy rainfall in Toronto.

Edit: alternatively u can just put a switch to have both fans blowing all the time. Should make it better during summer.

Once you put the air flow onto windows it automatically turns AC on for us (without the physical light being on). Or so i was told by a mechanic at the dealer.

What? I can't get mine to blow cold at all without the A/C on, if I turn off the A/C and leave the fans running it becomes unbearably hot after about 2 minutes unless it's under 75 outside. Do you mean you put it on "defrost"? Because that does run the A/C system.

What do you mean by "put the air flow onto windows"? If you mean the defrost setting then yes, it does turn on the A/C pump to dry out the air and reduce humidity in the car. Other than that setting you tell the A/C when to go on and off.

correct kind sir

mines pretty cold. unless I'm at a stop then its coldish...but this was discussed in another thread. It's colder when there is more airflow. If yours isn't cold at all I would def get that looked at

I only turn the AC on when driving over 4000 rpm and not accelerating, the A/C system running makes me lose too much power and doesn't blow very cold unless I'm in the power band.

If you had aftermarket pulleys, say like Tomioka Racing Pulleys, would the amount of power lost from the A/C compressor decrease?
