Re: AC question

Maybe you might want to consider going back to the R12 Freon. I just purchased seven cans of R12, 14oz, Original GM Freon, for just over $21 a can on Facebook Market place. No adjustment needed to your POA valve. R12 is still available on the internet. But prices seem to be around $70+ a can on these websites. You don't need any AC certificate if you are purchasing 32oz or less. You'll get better cooling if you go back to R12.

I now have a total of 9 cans of R12, enough to last me for years. I last charged my factory system 5 years ago. The system still doesn't need servicing. My POA valve needed replacing, so I used one of those POA valve eliminators designed for R12. I'm not wild about the way the factory air now cycles, but the AC in my truck keeps me cool in Arizona summer temps of 110+ degrees.
