I am going to try to give you the best advice of all the confusing posts you have seen in response to this question.
As of June 2014, Vermont did NOT prohibit the use of hydrocarbon-based refrigerants in automotive applications. Furthermore, as of that date, the EPA
did NOT prohibit retrofitting R-134a systems with hydrocarbon-based refrigerants.
That means, if the state and federal laws have not changed since then, and since your system has been converted over to R-134a with the intent of
using it that way, it is perfectly legal for you to replace the refrigerant in your system with Duracool, or similar product, which has a larger
molecule and will not leak down as fast, if at all.
You probably will not be able to find an automotive refrigerant mechanic that will do that, so you will want to do it yourself.
Now go back and find the posts that point you at the tutorials for doing the work yourself and let us know if you have questions.
