Hi roch,

When your friend said no freon left, he must have been refering to R-12,
because R-12 is known as freon.

ES-12 is a great freon replacement because it is compatible with the seals,
hoses, oil, and everything in the freon system.  It is more efficient and
performs better than freon (R-12) and is a much better replacement than R-134a,
which performs poorly compared to R-12.  EPA regulations require that the
charging fittings be changed to the R-134a type when converting an automotive
freon system.  The fittings are readily available and inexpensive (no more than
$10 total).  Since your freon has already leaked out, you would not need to
evacuate to recover any freon, and can symply add the RS-12.  To find info and
sources for RS-12 search the internet for "Enviro-Safe 12" or "RS-12."  As I
mentioned, the source I found and purchased from is:
