Well, got the system pressurized today. Was getting sub 50 degree temperatures in 85-90 degree temps, but i found a leak. Hopefully tightening up that hose stopped the leak, plus my can tap seemed to decide to leak on the last can. Will have to check it again tomorrow and see if I can get it cooler. Even with the giant parallel flow, it seems like I might have to run the high side pressures a little higher to get good cooling. Not sure.
If I cant get it working this time, I think I will bring it in to a shop and let them deal with it. My only theory is that the expansion valve got clogged or I am not getting enough airflow at the evaporator. I cleaned the evaporator coils with some foaming cleaner, but I suppose its possible that they are still dirty. Might try to get an evaperator temp measurement somehow to get a better idea what is happening.
