I had my a/c compressor and dryer replaced as the pully had a bit of a wobble, was making noise, and the bearing was potentially going out. It blew cold air but I'm not sure how cold. Even in the worst of summer it was comfortable in the front row. Now, not so much. Mid-90's outside and I'm running about 60-61 degrees at the center vent. When it was 100+ I was more like 70 degrees. The book says the temp split should be 30-40 degrees but I swear it ran much cooler before. Probable more than a 40 degree split. A few notes:
-New Denso compressor
-New dryer
-R134a system - 30 ounces approx. We even dumped the freon after a couple of weeks and started over as these are very sensitive to the correct amount of freon. Same result.
-System held vacuum for about 20 minutes to spec.
-Pressures are correct.
-Found this cool hack but it didn't help more than about 1 degree Adjusting water valve to maximize A/C performance - https://forum.ih8mud.com/threads/adjusting-water-valve-to-maximize-a-c-performance.173731/
-My rig has <160k miles on it. Not sure if the other compressor was the original.
Wondering if some of you could post your vent temps along with ambient air temps and looking for any help troubleshooting. Much appreciated!
