Sean, To answer your question: Yes, Freeze-12 can be added to a partially-charged R-12 system. Freeze-12 plays nice with R-12. I added some this year as I have a small leak somewhere. All it took was about 8 oz. from the 12 oz. can to make things right. I do have a stash of R-12 as well, but until I find the leak I don't want to add it. I would recommend checking the quantity and condition of the oil in your system, too. I picked up some pretty neat testers for just that purpose and they seem to work well. The AZ-D has all the tools needed to service your A/C system and we even have some spare Freeze-12. Drop one of us an email and we can help.
