Will Freeze 12 mix with r-12?

Freeze 12 is a refrigerant blend designed to be a drop-in replacement for R-12. It is generally compatible with R-12 systems, but mixing them is not recommended as it can lead to reduced efficiency and potential system damage. If you need to use Freeze 12, it's best to fully recover any R-12 from the system before introducing the new refrigerant. Always consult with a professional or refer to manufacturer guidelines for specific applications.
