You still have not read the EPA guide have you ?
Those shops do not think the extra time and labor is worth doing..
WHY do you not address the physical properties and theory behind the Nitrogen being used testing for leaks under pressure....
and the fact that the R22 can be legally vented into the atmosphere after a test to find any leaks.... and lets throw in again.. the fact that a dye used for leak checking will not find a leak in the evaporator or in lots of other hard to see...
Perhaps you do not understand the concept of ' Aficionado ' ...
aficionado Definition in the Cambridge English Dictionary
Perhaps you would understand if I described working on your own MB AC system as ' A Labor Of Love'.... I think our members trying to do their own AC work on these old cars fall into that classification... so them knowing the physics of the situation is entirely proper.. if they choose to use lesser methods that is their decision... it is their car..
but this is not how those shops see the job....
Do you deny that on home HVAC systems the industry standard of ' triple evacuation '.. meaning using the nitrogen multiple times AS the method of extracting moisture is legit ?
