    Would anyone decode these model Numbers?

    Would anyone be so kind as to decode these model numbers for me?

    I mainly want to know how old they are, but will gladly take any other description offered.

    I assume all the Carriers are 4 ton units, but how are they different?


    York DM120N20N2AAAD
    Carrier 48TFDOO8-A-511 3302630328
    Carrier 48TFDOO8-A-512 3302630322
    Carrier 48TJD024-580-AA 4101F15752
    Carrier 48TME012-A-501 3604630563

    The York is a 10, need the serial number.

    The Carrier 008 is a 7 1/2, I think.

    They are Carrier RTU's, gas fired, 208-230, and NOT 4 tons.


    ...and the 2002 unit is ready for a HX.....

    I know my carrier model units. I have nightmares that I'm being chased off the roof by 50TMs and 48TDs that morphed into transformers and need to extract service information from my frontal lobe with a egg beater

    Thanks everyone for the help. I know a whole lot more now than I did before.

    I could not make out a serial number on the York.

    I may have gotten some of the numbers slightly wrong, so if something does not make any sense, it may be because I could not read my own handwriting.

    They are definitely gas heat rooftop units

    There are a couple of 1988 yorks up there, too, still working fine, but I plan to replace those 2 this year anyway. I could tell they were 1988 because the sticker says manufactured 1988 on those. Which is good, because nearly everything else is faded out.

    Thanks again for helping me know what I got.
