Gonna go charge up the AC on Cinnamon in a bit. Looking at the procedure in the FSM, they put the cans in warm water. Any need to do this? Is that just to speed it up, or do you not get everything out of the cans otherwise?
Does it cool but not as well as it should? If so it might not need much. Add a little and let it stabilize watching the duct temp. Make sure your clutch fan is working properly.
