Which year did Volvo stop using Freon in its AC systems ?

  1. If it matters, I'm asking WRT to vehicles sold in Canada.

  2. My 1994 945TG came with the new A/C solution, if that helps.

    It was either 1992 or '93 that the new refrigerant was being used, of any vehicle sold in

  4. Thanks Myron.
    I don't suppose that Volvo proactively switched prior to '92 in order to be more
    responsible than "the rest" ?

  5. All 1993 Volvos had non-CFC A/C.

    THis is another reason why a 1993 Volvo 240 is the best 240.

    Right. All 92 Volvos used R12, all 93s R134a. I know this is true for
    North America, and I believe it is true worldwide.

    "Freon" is a Dupont trademark for hydrocarbons where some number of the
    hydrogen atoms have been replaced with fluorine, chlorine and/or bromine.
    The naming rules (e.g., Freon 12, Freon 134a etc.) are a bit complicated,
    but the formula for most can be arrived at by adding 90 to the number and
    noting that the resulting number interpreted as follows: first digit is the
    number of carbons, second digit is the number of hydrogens and the third
    digit the number of fluorines. The number of chlorines is gotten by taking
    the difference between the sum of the number of hydrogens + fluorines and
    substracting from the total number of available bonds to carbon. E.g.,
    Freon 12 gives 102 as the number, which is 1 C, 0 H, 2 F and 2 Cl (4-2 since
    C has four bonds available). So, Freon 12 is CCl2F2 or
    dichlorodifluoromethane. 134a gives 224, so 2 C, 2H and 4F--only 6 bonds
    available since the C are bonded to each other--so Freon 134a is C2H2F4.
    The 'a' has to do with exactly how the F's and H's are bonded to the C's

    That's the simplified version--a lot of words but pretty easy when you get
    the hang of it (assuming you've any reason to want to get the hang of it!).
    So--134a is still a "Freon", just not the one with which most are familiar.

    All 1993 Volvos had non-CFC A/C.
    It only cost me $175 to convert the A/C on my '92 240 the other day. And that
    was using new, real Volvo parts!

    That said, I'd rather it was a '93, sure.
