I've converted two AC systems to 134, and it seems that leaks keep happening...I know our cars are old - and to some extent that's bound to happen...but in a couple cases I replaced most everything...I'm wondering if my mechanic is putting in too much pressure. I believe the pressure or amount of refrigerant changes when switch form r12 to new refrigerant....right? If so, what is the ideal setting? If I'm recharging my system what's the cutoff?
