Hi All,
I just bought my 02 Coupe this past winter so I have no experience with the AC in the summer heat. I think the AC in my car is pretty lame. For the outside temp. around 85F, when I stuck in traffic, it is barely cold. If the car get moving, it is fine. I checked the AC system pressure(by myself), which indicate that there is enough refrigerant. No need to charge it.
I would like to know how are the AC systems in others cars perform. Do they as good as AC in BMW,Mercedes or Japanese car? I just want to know that is there anything wrong with my AC system.
Thanks,
pganmol

05 QP. no problem keeping it cold enough; however the thermostat process is often erratic. I often just use it in manual.

No problems with the AC being cold, separate issue with the semi-dead side vents, almost zero flow from those things.

But that is probably just a design issue, just an airflow oversight.

Temp works great.

The "Auto" mode is pretty much useless as far as I'm concerned but the car cools down well with som emanual fiddling. The number of days I really use the AC is another thing entirely.

Mine is an 02 and I do not have any problems cooling down, the AC works fine. I agree with RQ, the side vents have virtually no airflow. On the other hand the the center vents blast out the air and are extremely loud.

As far as I'm concerned, I live in hell (Naples, Fla) temperature wise. It is not uncommon for the interior temperature guage to register in excess of 110 degrees (at 100% humidity, mind you...not "Dry" heat). My '02 coupe is left on auto and 70 degrees. This is fine 95% of the time. It sounds to me you should have it checked out. I'm curious to know what temperature the air is at as it exits the vents. I believe there is an acceptable range, above which would suggest a problem. Good Luck!

My auto worked great and my AC was among the coldest I ever had. My heater was great too. I remember one October day it was really cold outside, I had the top down and the heater on with my khaki shorts and jacket. Alot of people looked at me as if I was crazy. Now that's a good heater.

I wonderd about this too now that we have had some recent hot humid days. Absurdly, I found that turning the auto thermostat higher (to around 22-24) degrees provided colder air from the vents than when set lower, so you might want to try that. otherwise, on auto, I am still mystified by what settings it chooses (recirculate vs circulate) or what the air flow speed will be set. Sigh...another Maser mystery.

Well, it was over 90 degrees today in So Cal, but I found the AC quite efficient at keeping temperatures inside the car cool. Yes, the side vents aren't the best, but there is quite a bit of airflow through the central vents and the dash (upwards) vent.

I am in Virginia, it gets real hot and real humid. The AC is very respectable. The only complaint is the fans/vents could use a bit more blow power-- especially with the sun beating down.

That said, the maser ac is better than any other Italian car I have been in.

My AC works very well and I use the "Auto" function.. it's not as efficient or cold as the BMW 330 I had - but that system was so overengineered it would numb my feet.

My only problem is the damn condenser has just decided it's a much better idea to empty itself into the footwells!
