No R134a is used only the cars, and R22 is only used for home central ac system. If you would like more information about R134a you can log on to www.idqusa.com.
No, an R134a compressor cannot directly replace an R22 compressor due to differences in refrigerant properties and system requirements. R134a and R22 operate at different pressures and have different lubrication needs, so using an R134a compressor in an R22 system could lead to inefficiency or damage. If converting from R22 to R134a, the entire system, including the compressor, evaporator, and condenser, typically needs to be modified or replaced to accommodate the different refrigerant.
sorry, no.
No
No
No use R22. R134A is for automotive applications.
No
r134a is a refrigerant (freon) added to the air-conditioning system. It has no color, but can be purchased with a dye (usually red) in it to detect leaks in the system.
After 1992- r134A Before 1992- R22 but it need to be retrofitted for R134 if it hasn't been done already. It is ILLEGAL to use R22 in autos.
There are so many Refrigerants in use that there is no way to answer this question. Best guess R22 or R134A
No
You really need to flush out the old stuff. But any garage can do it if they will.
Depends on what type of AC system it is. Some AC systems use water, which, of course isn't. The ones which use HFC and CFC refrigerants (R12, R134a, R212, R22, etc.) are, however.
