I have done some reading where R134a now has some controversy
surrounding it, as evidence mounts as to whether it is really all that
environmentally friendly. It seems that no matter what is done, there
are problems associated.

If your system has not already been converted to R134a, then perhaps you
might want to investigate the alternatives pretty thoroughly before
making the change.

For some time, I considered changing over to R134a, but after a lot of
reading decided to stay with the R12 for the time being. It does, after
all perform better and the system was designed for it.  My choice  has,
for the moment, settled on Freeze 12, as the best performing
alternative, should I decide to change out the R12.
