A/C pressures

toolmanmike said

I don't use propane but I would tend to agree. I read the op's thread title and thought to myself, I would have to look the pressures up on a chart. Last week they were different than today. I only look at the pressures if there is a problem. The duct temp is what I look at.

Mike you right
My system will only cool down to 50*F at the vents. That's way I was looking for pressures.
All the charts I found were for R-12 my has been converted to 134A
I thought this may make a difference, it didn't.
I going to dig in to today with a real set of gauges at a Buddy's shop.
I will report back
