Weatherking central air

[Bernard Rosen]

I have a Weatherking Central air unit with a totally blank id card, no model no. and no serial no. The Unit says Weatherking, Select 12, Legacy. The plastic cover for the ID card has imprinted the following:
92-22050-14-03
and 92-20842-15-00

I would truly appreciate it if someone could give me a clue to identifying the age of the unit and its model no.
Thanks

That s a tough one, I don’t think your going to get the date from that number. See this post.

Here is what I have:

HVACManufacture Dates From Serial Numbers on Condensing Units

AMANA / BLACKHORSEB=1971 or 1981 (Of course, now that they've been bought by Goodman, who knows what'll happen)


BARD1962 to March 1980 Sample Number 123456 A D
1st six digits are the Unit Identity Number. In this example they are represented by the numbers 123456. 7th digit is the month of Manufacture.
8th digit is the year of Manufacture. (The letter D in the Sample represents 1964).

1962 = B 1965 = E 1968 = H 1970 = K 1973 = N Letter “Q” not used 1978 = T

1963 = C 1966 = F Letter “I” not used 1971 = L 1974 = O 1976 = R 1979 = U

1964 = D 1967 = G 1969 = J 1972 = M 1975 = P 1977 = S 1980 = V

April & May 1980 Sample number 123 D A 123456
1st three digits are the Compressor Part Number. 4th digit is the month of Manufacture. 5th digit is the year of Manufacture.
In this sample A represents 1980. 1980 = A 6th thru 11th digits represent the Unit Identity Number.
This serial number style was only used during the months of April & May 1980.

June 1980 to Current Sample number 123 H80 1234567 02 1st three digits = Compressor Part # 4th digit = Month
5th & 6th digits = Year 80 = 1980 81 = 1981 82 = 1982 The year 2000 started the numerical numbering from 00.

00 = 2000 01 = 2001 02 = 2002 Right on through to current date. 7th thru 13th digits = Unit Identity #. 14th & 15th digits = Factory Code (01=OH; 02=GA)


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


ColemanSerial numbers prior to April 1992=1st two numbers are month, then year, then series.
After April 1992, 1st two numbers are year, then month, then series. Call 905-672-0860 if you get stuck.


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


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


GoodmanFirst two digits of the serial number are the year. Second two are the month.


Lennox Either the first two or second two digits are the year, it varies by era, but most of them actually have a separate sticker somewhere that has the year printed on it. Newer ones are first two equals manufacturing plant #, 2nd two are year and letter in fifth slot is month.


PeerlessPrior to 1984 there was not a date code included as part of the serial number. Starting in 1984, there was a four digit date code following the serial number that was month and year. Example – JO-12345-1084, this unit was built in October of 1984. Starting in the year 2000, same idea only it was a six digit date code following the serial number that is year and month. Example – 1234567-200105, this would have been build in May of 2001.
Anything without the addition to the serial number would have been made before 1984 and would require contact with the factory.


Rheem & Rudd WeatherkingSomewhere in the middle of the serial number will be a letter. The following four numbers are the week and year.


TRANEUses alpha codes in their serial numbers to determine year of manufacture. They started this in 1987 with the letter B and skipped a couple of letters during the years... The first letter of the serial number gives the year of manufacture as follows:

O, A=80(seventh digit) U=82(seventh digit) X=84 S=86 C=88 E=90 G=92 J=94 L=96 N=1998 R=2000

T=81(seventh digit) W=83 Y=85 B=87 D=89 F=91 H=93 K=95 M=97 P=1999 Z=2001

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


Weil-McLainPlease look on the outside jacket of the boiler for a CP Serial Number. It will have a bar code on it. Call (or email) Weil-McLain and they will tell you the date of manufacture. Phone: 219-879-6561 ask for Technical Services


YORK (Unitary Products since 1984)York purchased Fraser, Johnston and Luxaire in 1980.
Year of make indicated by 3rd letter in the serial number. Note: they skip the letters I, O, Q, U, Z.

1971 - A 1975 - E 1979 - J 1983 – N 1987 - T 1991 - Y 1995 - D 1999 - H 2003 - M
1972 - B 1976 - F 1980 - K 1984 – P 1988 - V 1992 - A 1996 - E 2000 - J 2004 - N
1973 - C 1977 - G 1981 - L 1985 – R 1989 - W 1993 - B 1997 - F 2001 - K 2005 - P
1974 - D 1978 - H 1982 - M 1986 – S 1990 - X 1994 - C 1998 - G 2002 - L 2006 - R

There may be another tag with model number inside control panel- Shut off power before opening; Compressor model number & serial number can tell you size and age if it is original compressor

Thank you for the suggestion. It is much appreciated.

Thanks very much for the extensive information. I appreciate it greatly.

When I am evaluating a HVAC system one of the first things; I make a mental note of are the furnace and the A/C unit the same age or has one or the other been changed out. Many times the tag on the outside condenser is not readable and if through my experience I determine that the furnace and the A/C unit are indeed the same age I will use the date from the furnace which in more cases than not is readable to determine age for the outside unit.

It is not a sure fire method but does work I high percentage of the time if you know what to look for.

Usually when you find a blank main tag with either a paper or plastic secondary tag, it means that the manufacturer and/or the manufacturing plant was shut down for some reason, such as a strike, a weather event in the area (hurricane damage, flood damage), etc. Usually in those circumstances, the manufacturer will outsource its needs to other manufacturers who were not affected by the strike, weather event, or whatever.

To identify such units, since they want to know how their outsourcing worked (did the subcontracting manufacturer live up to the contractor's expectations and/or requirements and/or reputation), they'll attach a secondary plate and leave the main one blank. On that secondary plate, you'll usually find two sets of numbers, as in your case. One number indicates the date of manufacture (and other information) of the subcontractor, and the other is the date the unit was received from the subcontractor by the contractor.

Consequently, I believe you have a unit that was manufactured by a subcontractor in the 20th week of 1992, the 842nd unit manufactured under the contract. It was the 50th unit received by the contractor, during the 22nd week of 1992.

Thank you for your excellent reply. The unit looks old enough to have been manufactured in 92 and I believe your info to be correct. My sincere appreciation for your help.

Thanks for your prompt reply. It is appreciated.
