Hey,
I was at an Indy shop a few days ago bull****ting with the owner. We were discussing AC systems. My symptoms were exactly as you described. One of my problems that the compressor never shuts off even at low pressures. This is the same with 3 different switches. But that's another story.

He was mentioning some things to me that I never thought about. Like maybe a collapsed hose on the inside that you would never see.
You never know where there can be a restriction.

He seemed to think I was undercharged but after talking a while it seems that more than likely there's too much oil in the system. I'm allready at 210# head pressure at 95 deg. It does just fine until the hottest part of the day or if the interior gets too hot. The coldest the center vent gets is 50 deg. When it's really hot out it takes forever to get to 70 deg.
At this point I'm done playing around with it. I just want it to work. I told him I would be back next Monday so hopefully then it will be fixed!

Danny
