FAQ:

Q: What happens if you put R134a in a R12 system?

A: What happens if you put r134a in a r12 system? The oils are different and not compatible and can cause an explosion. R134a is also a smaller molecule than r12 so if you HAD a small leak with r12 that you did not fix you have an even bigger leak now.

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: What do I need to convert from R12 to R134a?

A: Discharge the R12 and recover the R12 for recycling. Flush evaporator and condenser with AC flush kit to remove mineral oil Flush AC high pressure and suction lines to remove mineral oil Empty oil from compressor Add specified Ester or PAG oil in the proper viscosity to the compressor,condenser and evaporator.

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.
