The components of mobile AC systems are engineered specifically around the properties of the refrigerant used. Due to EPA regulations, R-12 refrigerant is no longer available and older cars require upgrade of these systems to accommodate newer, more environmentally-friendly refrigerants. These changes necessitate some hardware changes, and conversion products from FJC can help you navigate the process.
