Mark,

You really need a set of gauges to check the pressures on the high side and low side.  A 134a system really needs to be evacuated and re-charged to get a proper fill and performance.  It may work for a while by "winging it", but you can add too much and cause high pressures in the system that will cause you problems.  I can send you a procedure to charge the system if you are interested.  Too long to post here :)
