AC is cooling okay....as I noticed during charging the compressor is cut off as soon as vent temps are reaching 50F...Cooling is very constant and with 110F ambient I think I can live with this. It could be blowing colder but i think this is the temperature sensor in the evaporator causing the on and off cycle of the compressor.
Another thing that puzzled me was the high pressure at the low side (130psi!) This seems excessive. However I believe I had a problem with my low side hose that didn't fully open the Schrader valve and so I had a hard time to get the 3 cans charged. It took me literally hours to get the can filled in. So I believe the low side reading was not accurate.
