Freon to R134

[Greg Johnson]

Crew,

Hope I have the code number correct.  Have any of you upgraded from
Freon to R134.  If so, what did cost and how is it working?

I spoke to an AC place today and they indicated that if you have climate
control (we do) you might not want to upgrade.  I'm not entirely sure
what the guy was trying to relate, but he mentioned something to the
effect that there's a sensor on the compressor, and that if it the
sensor did or did not do something that R134 might not have enough
hutzpah to cool the system the way freon does.  Anyone know what the
heck he's talking about?

TIA for collective help and wisdom.
