How long does it take for your ac to start cooling the car?

I think from car to car A/C will vary. It does take little time for my car to cool off. but once it does it is like an ice box. The only complaint I have about the A/C is that ol so familiar odor you get when you first turn it on.

If I set both outer (left and right) ***** to auto... and set the middle **** to a temperature (like 75 degrees C) then I notice the car interior cools off very quickly. Big burst of air initially... winds down as cabin cools off. I think that works a bit faster than if I use AC manual settings -- works so well that way... I use auto settings most of the time.

To the question: few minutes, maybe five.

I leave mine on "auto" settings and 72 degrees. Also on really hot days, I'll remotely open the windows as I walk up to let some of the extra heat escape. That seems to help. It gets so cold after a few minutes, I usually have to turn the A/C up to 75 so I don't freeze.

If I put my hand in front of the ac vents, the air coming from the ac vent is cool but not freezing cold. As time goes on from startup the air slowly gets colder and colder. At anywhere from 5-10 minutes of driving the air will have reached max coldness. And it is then that the car begins to cool down.
I dont remember if the car has always been this way that is why I am asking you all to confirm this.
As a side note, I notice that after about 30 minutes to an hour of parking my car after a drive. I have a puddle of what I assume to be condensation coming from the ac. However when I look at other cars parked next to me, none seem to have one as big as mine. Anyone know if this could be a problem or if this is normal in your experience with your z?

Roll down the windows and put the A/C on full blast after the car has been running for a minute (pretty much from driveway to road or parking lot to road). Then leave windows open for a minute more, and the car will be freezing in no time. I have no complaints about the Z A/C, except for the fact that 75 is NOT 75. Its more like 70, I swear.

The cooler the air blowing through your radiator, the faster your A/C will cool the car down.
Your A/C drops in efficiency when the ambient air cannot cool the compressed refrigerant enough.
Think about how your AC works. It has to pump heat out of the hot part of the A/C system into the already-hot surroundings / engine bay. If the outside temp is hot, then it has less efficiency per cycle.

Its all about efficiency...
Dry weather cools better than humid...
Ambient outside temp matters.
Engine Compartment temp matters.
RPM matters.
Vent settings matter.
Internal Temp matters.
Its its 100 outside but your car is 130 then it will take longer too cool the air inside than the air outside to a point...
If your engine compartment is hot and your car has been parked then your AC radiator is full of heat and is less efficient untill you get moving. Higher RPM (up to a point) allows for your compressor to work better. recir works faster than fresh.
Mine takes no more than 5 min to get confortable after being parked int eh sun all day... if its 100 our or 80
Trick is to get hot air out and cooler air in.
If its 100 outside then your car is proably 120-130.
Get in , crack the windows about an inch, put it on full blast bi-level, cold, fresh air. After about 2-3 min the VERY hot air inside will have been mostly removed and you will have warm air. Put it on recir, close windows set it to auto and enjoy as the temp drops quickly..
If your in traffic it will take longer than if you are moving (15MPH or beter)

Normally my Z is in the sun, so the inside temperature is higher than outside. Still the AC on auto mode will switch to use cabin air only. The AC doesn't get really cold, so I always switch straight away to outside air. This makes it nice and cold...
