Greg, although the compressor can "handle" 134a, it won't last as long and your hoses won't either. Especially as you are in Ft. Worth, a much better option will be to get a 609 cert online (costs about $15) and then get R12 and keep it that way. In the end, it will be cheaper for you and it will work better.
