FAQ:

Q: How to put R134 into a R12 system?

A: Recover all R12 and dispose of it correctly. Remove all traces of the mineral oil. Re-charge the lubricant wit a polyol ester lubricant. Replace the expansion device with the appropriate device. Evacuate the system and replace the filter drier with a compatible drier. Re-charge with R134a to the correct charge by superheat,subcooling and sight glass.

Q: Can you put R12 in a R134 system?

A: As R12 used a different oil that was not fit to be used with R134a, the replacement was not that simple. But if your R12 system is working well and not leaking, you can still use it. The problem arises when the system becomes old enough, and the refrigerant starts to leak due to the weary case.

Q: How to tell if R12 or R134?

A: tfvesquire. I was pondering this issue over the weekend when I thought about diving into the HVAC system and A/C. Clarkz71. R12 will have threaded fittings at ports. … Fonzi. R12 can be purchased (for resale) on ebay. … rollin560 SinSL. … Fonzi. … SinSL. … tfvesquire. … rollin560. … roncallo. …

Q: Can you mix R12 with R134?

A: You cannot mix R-12 with R-134a, they are not compatible (and neither are the compressor oils used with them). If you have a R-12 system, you either need to use R-12 (make sure you fix the leak first, it’s currently selling for about $60/pound), or “convert” the system to R-134a (including having it flushed and evacuated).
