Mine sucks, added in 1 can of freon, and the vent temp went from 85 to 68. cabin temp still in the 80's WTH?? what kind of temps are you guys getting??
Do you have any details on how you did the insulation as well as what you used to insulate?Being in Florida and experiencing somewhat similar, disappointing and uncomfortable A/C performance as you, I made some changes recently that indeed seem to be working very well. I decided to insulate the cockpit of the car from two heat sources, the sun and the cars own hot fluid pipes. Firstly, I tinted every window, including the windshield, with 3M Crystalline, which is the latest in technology, expensive, but very effective. Secondly, I insulated the side sills and front firewall on the inside of the car from the heat of the coolant, heater and oil cooler pipes. I am now seeing vent temperatures in the 40's and the car is far more comfortable. The A/C is undersized for climate conditions where the temperatures are in the 90's and coupled with high humidity, therefore giving the system less to overcome certainly seems to help. Even when the vent temperature goes up in traffic, as soon as I start moving again the system recovers much quicker than before.

That sounds exactly like how my a/c works. It blows cold for about 10 mins when you first start the car then goes warm and sometimes comes back to cold for a minute or two before crapping out again.In my 05 the expansion valve was bad. I think this was the case in many units. My A/C would blow cool for a few minutes then no more. It was a warranty item I got repaired, all works well now.
