Refrigerant plays an important role in an AC. The best refrigerant is although R-12 only, but there is one more refrigerant that can be used as an alternative of it called R-134a. This is the only refrigerant which is approved to be used as an altenative. Do not even try to put some other refrigerant other than this, as it will be considered illegal.
