Even though that is not my quote (I just found the info on a site about Freeze 12), I believe it to be true. All shops (at least the reputable ones) will work with R12 and 134a only, and only have and are certified to use equipment for same. They are supposed to analyze the refrigerant before recovering it so their equipment and refrigerant supply does not contaminate other vehicles from the blended refrigerant. The tech at the shop I use calls it "refrigerant harpies" (refrigerant that has been contaminated with a "blend"). I for one am glad the shop I use will not allow their refrigerant supply to get contaminated, as I use them often. I know that I am getting pure refrigerant, and not a blend of anything else. I would have to agree that Redtek and other HC refrigerants can be vented legally and ethically. However, blends such as Freeze12 and the like should not.
Also, I have read that alternative refrigerants (including HC) are for replacement only, and NOT to be used for "topping off".
