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.
No.
No
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, you should not mix R-134a with an R-22 system. R-22 and R-134a are different refrigerants with distinct properties and are not compatible. Using R-134a in an R-22 system can lead to system inefficiency, potential damage, and could violate environmental regulations. If you need to switch refrigerants, it's best to properly reclaim the existing R-22 and retrofit the system for R-134a or another compatible refrigerant.
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.
No, R22 is for refrigerators and home AC. It runs at a different pressure and you can't use one for the other.
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?
You cannot directly use an R-134a compressor as a replacement for an R-22 system. The two refrigerants operate at different pressures, and R-134a compressors are designed for the properties of R-134a, which could lead to inefficiency or damage if used with R-22. If you need to switch refrigerants, it's advisable to replace the entire system or ensure that all components are compatible with the new refrigerant.
