Hi,
I am new to this forum and need some guidance in converting from r12 to 134a.

I have seen several comments in regard needing to install a High Pressure Cut Off switch and that there may be a combined High/Low pressure switch that can be installed on the dryer.

Any guidance would be appreciated as I am also replacing the comp, dryer, expansion valve, 2 hoses and all accessible o-rings.

Thanks,
Dan_H

 

Google R12 to R134a conversion and start reading. U r more likely to get good a/c facts/info from a/c pros who have written/published a/c conversion papers/articles. Too many times forums are full of opinions, rather than facts.
