Thread: Help with age of heat pump system

I have a heat pump system. The air handler's model number is F2RP030H06G and the serial number is A0K5944454. It's labeled Unitary Products Group which looks like it could be York, Luxaire or Coleman and I can't match anything in Preston’s or the Carson Dunlop tech guide. Also the condenser data plate is barely readable Model EABCF030SE and serial WGFP01579. That looks like a Luxaire Model number between the dates of 1999 and 2004. Any help is appreciated.
Thanks

K in the first serial # indicates 1980, & the F in the second 1976.

Sorry Jim, with that 2nd one being Luxaire the F is going to be 1997 & the K in the first one could be 2001 as well.

John,
Thanks. Where do you get this secret knowledge from? I found an "EABCF030SE..." under Luxaire by just looking for EABCF030SE. I looked under Luxaire because the air handler had Unitary Products on it. On the condenser I saw no brand. So, I used Luxaire from the air handler to match EABC in the luxaire listings, and found one. Geeez

Carrier, Bryant, Payne, Day & Night: Recently (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.

Coleman: Serial 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.

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

First Company Service Parts is 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.

Goodman: First two digits of the 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 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 (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 the middle of the serial number will be a letter "F" the following four numbers 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 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:

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.

Z=2001
R=2000
P=1999
N=1998
M=97
L=96
K=95
J=94
H=93
G=92

B=87
S=86
Y=85
X=84
W=83
U=82(seventh digit)
T=81(seventh digit)

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

Thanks John,
That is very helpful. I remember now a past thread where a few folks dicussed putting together a "dating guide" like was done for the water heaters. I'll have to try and find that one and see if one was deveveloped.

Speaking of water heaters, how does one tell how old a Bradford-White unit is? I believe BW is the only manufacturer that does not use the serial number/date of manufacture code/sequence.

Thanks.

Bradford White- 1st letter of s/n is the year of man with A being 1964,84,or 04. They use 20 yr cycles & skip letters I,O,Q,R,U, & V
The 2nd letter is the month A=Jan through M, leaving out I

Here is some information I stole from somewhere:

Bradford White

1st Letter is the Year of Manufacture

A = 1984 G = 1990 M = 1995 W = 2000
B = 1985 H = 1991 N = 1996 X = 2001
C = 1986 J = 1992 P = 1997 Y = 2002
D = 1987 K = 1993 S = 1998 Z = 2003
E = 1988 L = 1994 T = 1999 F = 1989

2nd Letter is the Month of Manufacture
A = January E = May J = September
B = Feburary F = June K = October
C = March G = July L = November
D = April H = August M = December

Using old date code reference sheets can get you in trouble, it did me so now I just check their website for the latest:

Bradford White | Find A Model/Serial Number


It's a dumb date code system as it keeps changing.

Thank You John G, Jim L and Joe K. Your help is appreciated.
