Was there no cap on the valve?Extremely common to find the valve leaking, a cap keeps it sealed.Rather that evacuate the whole system I would have put a new cap on (they have o-rings inside) and checked for leaks. If none: recharge and you are good to go for a few more years.The caps are VERY important, so if you don't have them: get them!Drew/actually has an MVAC license
