Hello all. After being in the HVAC buisness for 40 years I have heard "Refrigerant" called many names. The most popular of course is "*****", then "That cold Stuff", "freezone", and on and on. Well just when you think you have heard it all, today I came across a new one on a 1930's refrigerator ad, "The magic fluid". When I was in college learning this trade over 40 years ago, if we called refrigerant anything but refrigerant we got an "F" for the day, and chewed out by our Instructor. In all my time in the buisness from 1/2 to 3000 ton units, I have NEVER called Refrigerant "*****", even if it was made by Dupont, and its brand name was "*****"!

Any Thoughts ?

Take care
