I'm not sure what you have there but around here R12 was eliminated in 1993. Systems that were engineered for R12 do not always work well when R134a is put into them. Some retrofits require additional fans and you need to remove all of the mineral oil from the system.

In my country r12 is still available.I have flushed all the system. And replace oil as well. But still with r134 im not getting cold air at the vents. Is there any other solution? Somebody told me to replace the compressor pulley so that it runs faster than original. Is it good. Or it will harm the system or engine.
Please help me.
Thanking you.

So, why are you not putting R12 back into the system?

And what about compressor pulley. If I replace the pulley. To run the compressor faster than before.
