Convert my 240's air conditioning to R134a?

The prices my mechanic is quoting me to either recharge my '92 240's AC system
with Freon, or to convert to R134a, are pretty darn close. This is due to the
fact that I almost certainly need a significant amount of Freon (AC blows cool,
but just barely, and compressor short-cycles) and Freon is so dang expensive.
Anyway, any reason NOT to just convert the system? Furthermore, if conversion
is truly a viable option, is is something I can do myself with one of those
kits from the auto-parts store?

I'm hearing $200-ish to service the Freon system I now have, and $300-ish to
convert. If I convert, I can just put a can of 134a in there for two bucks if
needed at some future date... that'd be nice...

the 134a doesn't cool as well as the r12, mostly at idle, the 240's a/c is not
that great even at it's best, so id stick with the r12 if possible.

You can't legally revert it back to r12 after conversion. No shop will do it
because of the EPA fines :-(

The cost of 134 compared to R12 should make the conversion cheaper. All you
need is a screw on fitting to allow you to use 134 connectors. The 240 AC
was never good. The conversion will mean a loss of 3 or 4 degrees. But it is
cost effective.

Do the conversion, it'll need recharging again sooner or later, may as well
have it use the cheap readily available stuff.
 
134a
Is this enviromentally friendly or good?
The r12 is not, thats why it illegal to use it now.
Think skin cancer.
 
the 134a is better for the environment but is more harmful for humans if you
come in contact with it.
 
134a will not be as efficient as the original but, doesn't cause Ozone loss
which affects the greenhouse heating. ed
