FAQ:

Q: Is 1234yf compatible with R134A?

A: R-134a and 1234yf systems are very similar to each other. In fact this was one of the reasons that 1234yf was chosen as an alternative refrigerant. A few of the major differences can be read below: Slight design differences in the design specs of certain components like TXVs, ports, evaporators, and condensers. …

Q: Can I add R134a directly to my R12 system?

A: Can I add R134a directly to my R12 system? No. Federal law prohibits topping off an R12 system with a different refrigerant. Your options are to locate some R12, however you must be certified to purchase, and add it with an R-12 recharge hose.

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.
