Volks, Lurkers et. al.,
It is summer in March here in SE Texas, thanks to the "little boy" (I'm
tired of "el nino"). I have to mow my grass!! So back to A/C probs
again....
Volks, run the archives, you may use FR-12 and other concotions,
(propane will work fine!), just remember, if you have to pay an auto A/C
mechanic to service your system with FR-12 or other "substitutes" he
very well might not work on your system for he will not have a recovery
machine dedicated to recovering FR-12 and the other potions being
concocted. HF-14a is my choice (and industry standard) when my 87GL
needs converting, (not yet praise the Lord!), for apparently it works
great in all of the older systems setup for R-12. My friend who runs an
auto A/C shop says that they are lowering the volume of HF-134a, lower
than a 1:1 ratio old to new originally proposed and this seems to cool
as well as R-12. If HF-134a will cool well down here, it will work most
anywhere and you can get your system easily serviced by any auto A/C
shop.
The pitch that your old lines will leak the smaller particulate sized
HF-134a has proven totally false. A lot of this misinformation stems
from the newness of having to do these retrofits. As I understand it,
only the O-rings in the lines will have to be replaced, the system bled,
recharged and probably a new filter-dryer installed and all will cool
very well.
We do like our A/C down here in Texas!!
