Just wondering if somebody with a properly working AC and an IID tool could post what pressures they're seeing on the high side of their AC system. My AC works reasonably well most of the time, but I've been having it completely cut out seemingly at random. I used my set of gauges to add some R-134a last year and it seemed to take much more than I thought it would. Now, when looking at the pressure with my IID tool, it seems very high at 2300-2500 kPa and I'm wondering if I really did overfill the system. I know it's very temperature dependent and it's about 95-100 degrees here today, but I would just like to know "ballpark" what other people are seeing. Thanks!

 

The chart below should be helpful. Sound like you're in the general place (if not a bit high) based on high side pressure at 100 degree F.
