No, you cannot use R-22 in a system designed for R-134a. These refrigerants have different chemical properties and pressures, which can lead to system inefficiencies, potential damage, and safety hazards. Using the wrong refrigerant can void warranties and violate environmental regulations. It’s essential to use the refrigerant specified by the manufacturer for optimal performance and safety.
Not unless you like the idea of destroying your AC system.

Is r-22 Freon compatible with r-134a freon?
Your AC won't work any better than it did before. Two very different refrigerants, which will not blend, with different superheat points and system pressures. Not to mention that R22 won't carry PAG oil through the system as effectively as 134a, meaning you could end up starving your compressor of lubricating oil, thus burning it out.
No, R22 is for refrigerators and home AC. It runs at a different pressure and you can't use one for the other.
No. the pressure are different, r22 runs at a fairly low pressure and you shouldn't be worried about blowing your gauges, but you won't be able to determine your super-heat or sub-cooling. for a about $100cdn you can buy the right gauges.
Unless your system has been convert to take R-134a you would need 25oz of R-12. If your system has been convert to R-134a you would use 20oz to 21.25oz of R-134a.
No
NO ! and Why?
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.
