Good friend who's been in the A/C and radiator business for 40 years. Just related this to me today.
Seems that someone got the bright idea to add sealer (alias miracle stop-leak) along with the 134a. Bad BAD idea.
He's had to rebuild his charging/evacuate equipment because of it. Major expense for him and A/C system on the car.
This one area most definitely left to the folks who work with this everyday.
Just like 134a has been found to causing more problems than R-12. DUH
Nothing more than big business lobbying politicians all in the disguise of ozone layer. This is one of bigger rip-offs for the American consumer. Why else has the EPA required the A/C shops recover 134a and return the old stuff for safe disposal? But the public been allowed to vent it???? Sounds like Wisconsin's wiser than DC.
134a will be pulled off the market in the future.
Remember all the noise about converting your R-12 system to 134a,all big rip-off to keep money moving in the economy for the greedy rich (that covers the majority that's behind the scam.) R-12 is still available, it never was removed as far as the repair shops (EPA discourage them for using it),just more expensive $600-$1000 for a 30lb can vs. $34 15 years ago.
Chlorine's the component in Freon that causes the supposed problem. Nature produces 99% of chlorine that's supposedly damaging the ozone, Freon equipment less than approx 1/10th of a %.
And one other tid-bit R-12 and the HVAC R-22 The new refrigerants are not as good as the old refrigerants and attack the equipment and require special oils. The old refrigerants will last indefinitely. And I can't find it now, but if Freon is placed in water it will decompose naturally. I think I worded that correctly?
That's gist of it.
End one of many Rants. The more inside stuff I learn about the more greed and corruption I find that's slowly coming to the surface.
