A note for a/c DIYers..

The R-12 Refrigerant in your autos is a CFC refrigerant [chlorofluorocarbons]

The use of the word "FREON" is not a type of refrigerant, but rather the Copywrite Brand Name of refrigerants made by Dupont.
Refrigerants can be from the Genetron Co and be the same R-12 HFC, but it is not Freon..it would only be Freon if it was a Dupont product CFC.
This used to be a common accepted term to refer to refrigerants, mainly b/c Dupont was first to replace sulfur and ammonia as refrigerants due to their toxicity, but with all the new refrigerants on the market today, it is only used by those outside the trade..the correct term is simply Refrigerant...
..but freon will do fine here...

I can remember way back when guys also just called it "GAS"..
...when a guy would come in and ask us if we could put some GAS in his a/c, we would say.. " Sure, you want HighTest or Regular????"
