Is there anything compatible with R12 refrigerant?

R12 refrigerant is not compatible with most modern refrigerants due to its chemical structure and the fact that it is a CFC, which has been phased out due to environmental regulations. However, some alternatives like R134a and R404A can be used in systems designed for them, but retrofitting is typically required. It’s essential to ensure that the lubricants and components in the system are compatible with the new refrigerant to avoid system damage or inefficiency. Always consult with a professional before making any changes to refrigerant types.
