    Default How old is my Carrier?

    I have a Carrier window unit and I'm trying to find out when it was manufactured.

    It has a 'Date of MFG' stamp on it but i can't make it out.

    I thought I could figure it out with the Serial # but none of the info I've read on how to determine the date makes any sense with this #...in fact i can't find any info on the model # or serial #

    Please help.

    Looks like it says "87" on it, so I say that it was probably manufactured in 1987.

    That's old for an a/c unit.

    Thank you '87 was my guess...but it could be a 97 or even a 67...i was really hoping for something a little more solid than a guess tho.

    You can look at the label, I can only look at the photo - the photo looks like it says "87", which would mean either 1887 - which we know it is not that ... or 1987, which is a lot more likely than 1887 ... and it is not yet 2087 ... so I think it means 1987.

    That is from the photo - now, with you looking at the label, if it says something other than "87", then that would be the year - because it says so on the label at "DATE OF MFG", which stands for 'Date of manufacture' and then it gives you that date.

    It looks like ... "looks like" ... the label gives a month and year, with the month being not legible in the photo, and the year being "87" in the photo.

    That is the best I can do unless you can get a better photo of the label which clearly shows what is scratched into the label at "DATE OF MFG".

    That's like an old typewriter I have (remember those things?), stamped into the casting is "S/N" (which stands for "serial number", and next to it is "8-2", and, being as the typewriter is a "L. C. Smith Type 8", that "8" is the type, versus their Type 5, etc., and the "-2" is serial number 2 ... the second Type 8 typewriter off their production line.

    Why? Because it says so on the label - just like it says on your label.

    How do you get 97 when the 3rd and 4th are "S" and "7"?

    HVAC AGE CODES IN SERIAL # INFO

    DUCANE: Excel Cooling Products
    How to read a date code off serial numbers for date of manufacture
    Serial numbers must be 10 digits

    441390311 -----
    03 is the year
    11 is the week (March of 2003)

    Branded Product serial numbers

    8402F11665
    84 is the plant location
    02 is the year
    F is the month (Ex. A- Jan, B- Feb, C- Mar, etc.


    Amana: BLACKHORSE. B=1971 or1981. (Of course, now that they've been bought by Goodman, who knows what'llhappen.)

    BARD 1962 to March 1980
    Sample Number 123456 A D

    1st six digits are the Unit Identity Number. In this example they arerepresented by the numbers 123456.

    7th digit is the month of Manufacture. (The letter A in the Sample representsJanuary).
    A = January
    B = February
    C = March
    D = April
    E = May
    F = June
    G = July
    H = August
    Letter I was not used.
    J = September
    K = October
    L = November
    M = December

    8th digit is the year of Manufacture. (The letter D in the Sample represents1964).
    1962 = B
    1963 = C
    1964 = D
    1965 = E
    1966 = F
    1967 = G
    1968 = H
    Letter I was not used.
    1969 = J
    1970 = K
    1971 = L
    1972 = M
    1973 = N
    1974 = O
    1975 = P
    Letter Q was not used.
    1976 = R
    1977 = S
    1978 = T
    1979 = U
    1980 = V


    Bard April & May 1980

    Sample number 123 D A 123456

    1st three digits are the Compressor Part Number.

    4th digit is the month of Manufacture. In this sample D represents April.
    D = April
    F = May

    5th digit is the year of Manufacture. In this sample A represents 1980.
    1980 = A

    This serial number style was only used during the months of April & May1980.

    6th thru 11th digits represent the Unit Identity Number.


    Bard June 1980 to Current

    Sample number 123 H80 1234567 02

    1st three digits = Compressor Part #

    4th digit = Month
    A = January
    B = February
    C = March
    D = April
    E was not used
    F = May
    G was not used
    H = June
    I was not used
    J = July
    K = August
    L = September
    M = October
    N = November
    O was not used
    P = December

    5th & 6th digits = Year

    80 = 1980
    81 = 1981
    82 = 1982
    right on thru. The year 2000 started the numerical numbering from 00.
    00 = 2000
    01 = 2001
    02 = 2002
    right on thru to current date.

    7th thru 13th digits = Unit Identity #

    14th & 15th digits = Factory Code (01=OH; 02=GA)


    Carrier, Bryant, Payne, Day &Night: Recently (last 20 years or so) the first four numbers in theserial number represent the week and year. Previously, it was a complex seriesof letters and single digits. Call 905 672-0860 if you get stuck.

    Coleman: Serial numbers priorto April 1992=1st two numbers are month, then year, then series.
    After April 1992, 1st two numbers are year, then month, then series.

    Comfortmaker (International Comfort)uses the first letter for the month (skipping I) and the first two digits arethe year.

    First Company Service Partsis one of 4 divisions of First Operations. They supply OEM equipment to all ofthe major HVAC manufacturers. They are located in Dallas, Tx at 214-388-5751.Harold Hammer at Tech Support (ext#5) will answer your questions.

    Goodman: First two digits ofthe serial number are the year. Second two are the month.
    Btu rating is model number..ie; GMP075-3 (75,000 bonnet input)
    Compressor is same :serial # 9709088872 (yr1997 wk 09) Tonnage is model #CK361C The first two numbers after the CK (letters) divided by 12 is tons. ie:36 div by 12= 3 tons.

    Lennox: Either the first twoor second two digits are the year, it varies by era, but most of them actuallyhave a separate sticker somewhere that has the year printed on it. Newer onesare first two equals manufacturing plant #, 2nd two are year and letter infifth slot is month (A thru M minus I). So 5898G 07568 would be Plant # 58,Year of MFR would be 98 and month would be July.

    Rheem & Rudd: in themiddle of the serial number will be a letter "F" the following fournumbers are the week and year.
    The first letter of the serial number gives the year of manufacture as follows:

    TRANE
    Trane uses alpha codes in their serial numbers to determine year ofmanufacture. They started this in 1987 with the letter B and skipped a coupleof letters during the years........ The first letter of the serial number givesthe year of manufacture as follows:

    In 2002 they started their serial numbers with the year it was built. In 2002the first character of the serial number is 2, in 2003, 3 and so on.

    Z=2001
    R=2000
    P=1999
    N=1998
    M=97
    L=96
    K=95
    J=94
    H=93
    G=92
    F=91
    E=90
    D=89
    C=88
    B=87
    S=86
    Y=85
    X=84
    W=83
    U=82(seventh digit)
    T=81(seventh digit)
    O, A=80(seventh digit)

    The great majority of gas furnaces that I see are made by Carrier and sold under a variety ofbrand names - Carrier, Rheem, Bryant andothers. These are identified by the first four digits of the serial numberby week and year beginning around 1980. Before that, they used the first twodigits as the week of the year and a letter to represent the year, beginningwith R for 1964 skipping the letter z and ending in 1979 with the letter H.

    Tranefurnaces have a long serial number with the week and year appearing late in thenumber immediately after the letter F.

    Amanauses the code Blackhorse. S=1969, E=70, B=71, L=72. It goes in 10 yearcycles, so:

    B=71, 81, 91, 01 H=76, 86, 96, 06
    L=72, 82, 92, 02 O=77, 87, 97, 07
    A=73, 83, 93, 03 R=78, 88, 98, 08
    C=74, 84, 94, 04 S=79, 89, 99, 09
    K = 75, 85, 95, 05 E=80, 90, 00, 10

    Lennox -Before '74 lst two digits equal the year, next digit the month. ex: 724XXXX =April 1972. After '74 first two digits equals the plant, 3rd and 4th the year,5th (A letter) equals the month. A=Jan but I is not used.

    On old oil furnaces that look like they are from theWWII era I open up the air handler and look at the blower drum. A lot of themhave the date stamped right there on the drum housing in purple ink.1946, 1947, etc..

    Thermo-Pridedoes not code their units by serial number but they do keep a record ofevery unit sold. You can contact them directly, give them the model and serialnumber and they can tell you when it was shipped from the factory.
