My 2012 AC is definitely not as good as when they had freon. Has anyone else noticed that everytime the govt gets involved things get worse. How's that govt mandated ethanol. How about the govt mandated egr and dpf on the diesels. I cant even smoke a cigarette without having to relight it all the time. About a year ago they announced that the average life expectancy had increased a whopping 1 day because of the govt mandated changes. Golly how many thousands of dollars will I have paid to live that extra day.

My 1995 would blow Ice Cold and you would have to turn it off it would get so cold in the cab.......even on the hottest of days. In these new ones I have yet to turn the system off. Just not as good as they used to be.

Took mine to the dealer with the same issue and they added a can and a half of freon. The dealer said that they have had to perform this on a lot of newer f150's. I guess this is a good way to save money?

Just checked the tempature at the dash vent with the fan on high. Air from the vent is 43 degrees F. The outside temperature is 72. I am no expert but the system seems to be cooling the outside air 29 degrees, which seems good. I'll try it again tomorrow when it is at least 85 outside. For some reason, it doesn't seem to cool the cab when driving and over 80 outside.

My '11 F150, as well as my old '06 F150 always "seemed" to not blow as cold of air as our other rides ('02 Explorer and '02 Taurus). Those cars get downright cold, and you have to shut the air down on a hot day or you freeze.
Funny this thread came up. I just got done properly charging up my '95 beater Ranger with R134a, and it felt quite cooler than my new '11 F150. But, checking both at the vent with a thermometer, with A/C on Max (recirculating), at idle on a 80 degree day, the Ranger blows 37 degrees, and on a 75 degree day, at idle, the F150 blew 40 degrees. I did see 39 degrees out the of F150, when going down the highway.
So, the F150 does appear to not blow quite as cold, but its only 2-3 degrees different. I suspect it has to do with cab space, and distance you sit from the vents, to be part of the difference in "feel". I also suspect, in a effort to increase those MPG numbers (every little bit adds up, for instance electronic steering, air dams that drag the ground on 4x4's, and adding realtime MPG displays to encourage a lighter foot), recent F150's are charged a bit on the light side, to let the compressor run with less drrag on the engine. Just my guess.
I haven't hooked up my manifold gauges to the '11 F150, and probably won't unless I notice a drop in cooling from 40 degrees. But, I suspect these F150's could take a little more R134a, and you could see 36 degrees out of them, on a 90 degree day, if you were so inclined. I certainly wouldn't over charge it though, just to get a few degrees.
