Question -- I have a R134 conversion (compressor/dryer) on the old hoses. I generally have it evac, leak tested and charged in the spring and by the fall or the following spring (when i remove it from storage), the charge is gone.
Can i top off during the year using an auto parts store kit or is a full evac always necessary?
I know barrier hoses are the soln, but So far - this hasnt been too much of a hardship and my vent temps can handle 90+ degree days when i do use it (which isnt that often).
