Mixing 134 and R12 is against federal law. Not thatÆs is going to be a huge deterrent, do whatever you want. My take is that that once you have the two gasses in one system its hard for a shop or the next owner to properly dispose of the refrigerant, unless you "Vent" it.

The good thing is the ozone layer is getting better and by 2050 it should be back to what it was in the late 80's.

If you convert to R134 and donÆt change out the mineral oil the compressor life will be pretty short. Mineral oil is not miserable in R134. It wonÆt flow with the refrigerant so the compressor wont get a constant supply of oil.

There were a lot of studies done on conversions and the failure rates. Even done right the R134 conversions had some problems but nothing like the failure rate of one thatÆs done wrong.

The down side is R134 is a serious greenhouse gas.

Just so you know....If ANYONE calls me a tree huggerà. IÆm going to call them a moron. <img src="/forums/images/graemlins/notooth.gif" alt="" />


Seriously, ItÆs easy to take shortcuts and say what one person does wont matter. Its just me, I donÆt believe in the ozone hole and r12Æs effect on it and whatever. The problem is lots of people have the same attitude and repeat the same action to the point where it makes a difference.

I know... What socalist, liberal, Obama voting a tree hugger. <img src="/forums/images/graemlins/rodent.gif" alt="" />
