    What year was this Carrier furnace built?

    Model: 58GC100
    Serial: K256293

    Based on Carrier's website I think it means 1972, but I don't think it could be that old, could it?

    Don't recall a 58GC in the last 20+ years. Certainly not from the 90s. Could be 70 something...

    K is the month,2 is the year.Not 1992 because the "code" was changed before that ,82 or more likely 72.

    I think they are those robbin egg blue beasts with the two wire bimetal flame prover. The long, flat, wide ribbon burners and the funny burner strap that liked to rott through.

    I won't ponder a guess, but why do manufacturers want to keep it such a secret what year equipment was built? I like the way Trane, Rheem and some Carrier models print clearly the month and year of manufacture on the info plate.

    Carrier serial #'s:

    7 digits = pre 1969
    1 Letter (A-L (Jan-Dec)) + 6 digits (first being the year) = 1970-1979
    1 Letter (M-Z) + 6 digits = first part of the 1980's.

    After about 1985, the serial numbers are much easier
