An R12 system must be retrofitted to be made compatible with R-134a.
No the whole system need to be evacuated of the r22 before you put r22a in the system. It's against the law to mix 2 different freons together and also dangerous.
Whenever you retrofit a system to R-134a, you should replace all the oils, seals, and gaskets to ensure compatibility with the refrigerant. R-134a requires a different type of oil (such as PAG or POE) compared to R-12, which can lead to system inefficiencies or damage if not replaced. Additionally, old seals and gaskets may not be compatible with R-134a, leading to potential leaks. It's also advisable to replace the receiver-drier or accumulator to remove any contaminants from the old refrigerant.
You can use up to 21oz of R-134a. But don't forget if you are needing to add R-134a you will also need to replace some of the oil also.
R134A, R22A, R404A, R410A and many more
No, you should not mix R22 and R22a refrigerants together. Mixing different refrigerants can lead to system inefficiency, reduced cooling capacity, and potential damage to the equipment. It is important to use the correct refrigerant specified by the manufacturer for your system.
