never mix these freons together---- very dangerous
R-134A
No, you should not mix R-12 and R-134a refrigerants. They are chemically different and have incompatible properties, which can lead to system damage, inefficiency, and potential safety hazards. Additionally, mixing them can make it difficult to service the system and comply with environmental regulations. Always ensure that the refrigerant used matches the specifications of the system.
No, a 12 oz can of R-134A refrigerant is equivalent to 0.75 pounds.
No
Probably uses R-12 refrigerant but if you are having a problem with your ac you should convert to the new R-134a refrigerant . Look for a decal under the hood or on the compressor to make sure. The two refrigerants do not mix.
R-12 is very harmful to our enviroment.
The example of CFC is R-12. It is being used as a refrigerant.
R-134a is the only refrigerant approved by the automotive industry. It requires conversion to be used in an R-12 system.
If it is the original refrigerant, it's R-12 (which is not longer available). If it was converted, it has R-134A. You can tell by the type of service port (the fitting for replacing the refrigerant). The service port for R-12 has threads, R 134A does not.
No its not. 409a is compatible with r-12 but not 134a.
The short answer is yes. However, the A/C system must be retrofitted (changed from R-12 to R-134a). Many people believe that you can simply add R-134a in place of R-12 without retrofitting. However, this is not recommended because you can do damage to the A/C system. Remember that you are mixing two different refrigerants and refrigerant oils.
