Can MP39 refrigerant be used in a r22 ac system?

MP39 refrigerant is a blend designed as a replacement for R-22, but it is not recommended to be used in R-22 systems without proper retrofitting. While it can be compatible with some components, using MP39 in an R-22 system may lead to efficiency issues and potential damage. It’s essential to consult with a certified HVAC technician to evaluate the system and determine the best course of action for refrigerant replacement.
