I've had my '13 GT Cabrio for over a month now and recently started using the AC. (normally my top is down).

Is it me, or is the AC not as cold or efficient as other cars? Maybe mine needs to be recharged? It's cold .... but the cabin really doesn't get as cool as other cars I've owned, even after leaving it on for a while.

All cars have their quirks, just wondering if the AC on these cars is not as good as others.

Different car, I have a QP.

But mine gets cold enough to store beer. I find I have to manually up the fan speed, if I leave it in full auto mode the air flow is not adequate in high ambient.

Also, it seems to need to get permission from the Vatican, because there is often a long delay between when I start the car and when the A/C starts blowing cold. Like sometimes 5 minutes or so. Blows warm-ish air, then suddenly gets real cold.

I own a 2012 QP5 GTS. The AC is not as efficient as, say, in our 2006 Lexus GX 470, but it does get cold after a while; in fact, I sometimes need to raise the temp a bit. I suspect my experience is typical and do not think my unit is misbehaving; just a characteristic of the unit...

Yes it takes a long time and it does indeed get “cold” after a while , but ( in my experience ) if I had to use a comparison I’d say it’s at least 30 % less cold than any other car I’ve had. And I’m not comparing it to American sedans of the 70s and 80s, those damn things will grow icicles on your windows within half a minute of turning the AC on:grin2:. Compared even to my Porsches which are supposedly notorious for weak ACs, it’s still not nearly quite par with those . And the Mercedes sedan is also colder . The Jeep Grand Cherokee , in spite of a far larger cabin is by far the coldest AC of the cars I currently own. As I said, the GT AC system is fully and perfectly charged ( and not overcharged ) so can’t blame it on lack of “ cool juice “ .
There is another thread here where someone mentioned there is a new replacement for our R134 , namely 152A which has been used in Europe for while , and which produces noticeable cooler temps. By 15% or so at certain RPM levels . But scientific theories are abound indicating it also puts greater pressure on the compressor / condenser and it could lead to premature wear of the AC system. As much as I loove my cabin to feel like a freezer , I’m too apprehensive using that 152 until it has been time-tested ( IN OUR CARS ! ) and no problems are reported.

The AC in my '18 isn't as strong as I'm used too, but I'll put up with it given how amazing the car looks and sounds :)

The A/C on these cars isn't terrible, but it is not badass either...You have a pretty sloped hood on a GT so the condenser can only be so large....Hard to compare to American trucks etc. with that huge front grill and a lot of area...Good A/C should feel like a cold glass of ice water on the back hand out of the center vents going down the road...That is a very basic way of checking.. Get a thermometer or a cheap temp gun to get a better idea...You should be able to get down to high 40 degrees under most conditions....A/C is not as efficient at idle or sitting still....Jason

Very much agree with Jason.
I will add my 2016 GTS notoriously get colder after about 15-20 minutes vs. the first 15-20 minutes in my other American vehicles.


My Ford and Chevy get cold on a hot day within a few minutes.....the GTS gets there, just takes like 10 times as long.

Just a couple of thoughts:

Is the recirculate button lit? Also, if the evaporator is clogged or not getting good airflow across it that can contribute.

Double press the Auto button and it goes into a max type mode

:surprise: I have never double-pressed that button, maybe that’s the the reason I’m not getting the coldest possible air ..Will try that today and see if I can feel any difference . The recirculate button is always off. But I also turn off the “rear” button ( which comes on automatically when the AC is on ) to keep the maximum amount of air bowing in the front; however, I wonder if by eliminating a more direct cooling of the rear area of the cabin, it somehow causes a less efficient way of cold air distribution overall and hindering the optimum result ?

The only thing double pressing the auto button seems to do is activate the recirc air ( that button’s light comes on ) and it simultaneously changes the temp from LO / low, up to the next setting at 59, and ending the AC, so converting to just the ventilation function. It just causes the fan to blow harder but not with cooler air ..
Eh, I’ll just have to live with the AC the way it is , not the best , but good enough or rather , “ cool enough “ ...after a while .

My AC sometimes comes on randomly and shuts off randomly.

Maybe it's haunted? :laugh2:

Judging from these responses, I wasn't imagining things nor do I need to recharge my AC.

Not sure if I should be happy about that, but in the end I'm still driving a GT. :)

I actually enjoy the sometimes odd behavior of this car. It's entertaining. If I wanted something boring, I'll go drive my Volt.

Ok I have mentioned it on other similar topic posts. I have a 2002 spyder. I can run the AC with the windows and top down, in 95 degree Georgia heat and still feel it cooling me up to 45-50 MPH. I love it!
Now the problem is: it has no modulation. On or off. I cannot get it to hold a temperature. So I wonder about those with issues. It may not be the System but the control. It may not be holding the compressor on and the fan moving air.
I cannot get mine to switch on and off in a way that controls the output air temp. Again if I adjust the temp setting it snaps from AC on to off and no matter what: Never switches back. So maybe other have similar issues but never get it to stay on?
