Hi, this is not about an actual air conditioning problem, but about the terminology.
I am aware of the difference between R-12 and R-134a, but can anyone tell me whether there are people out there who call "R-134a" by the name of "R-12", or vice-versa, either formally or informally, and either accidentally, or on purpose?
And also, is "freon" the same as "air conditioning refrigerant"
Thanks for any help!
