Age Identification Of York Electric Furnace

[dtontarski]

Can anyone advise me on how to extract the age from these numbers:

Model Number: MKPS334680

Serial Number: N2AHD14A06A

Thanks.

I'd try 1992, Mike had a furnace age chart up a while back. Likely is in the archives.

Hi,

Yeah, the furnace decoder chart is in the file library under Heating Systems. I last updated it in March. Just remember that it's compiled from notes sent to me from inspectors around the country and not from any authorative source, so I don't guaranty it's accuracy. That said, based on my own experience I think it's probably better than 90% accurate. Unfortunately, there isn't a lot in there about boilers. I once tried to begin compiling information for a boiler chart but I didn't get a whole lot of contributions; I think the reason might be that there are too many brands of boilers and the serial number systems change even within the same company's products.

Anyway, Fraser, Johnston, and Luxaire were purchased by York in 1980 and York has been Unitary Products since 1984. The year of manufacturer is indicated by the 3rd position in the serial number beginning with the year 1971 and they skip the letters I, O, Q, U, Z. So, if the chart is accurate, the letter A is either 1971 or 1992.

1971 - A

1972 - B

1973 - C

1974 - D

1975 - E

1976 - F

1977 - G

1978 - H

1979 - J

1980 - K

1981 - L

1982 – M

1983 – N

1984 – P

1985 - R

1986 - S

1987 - T

1988 - V

1989 - W

1990 - X

1991 – Y

1992 – A

1993 - B

1994 - C

1995 – D

1996 - E

1997 - F

1998 - G

1999 - H

2000 - J

2001 - K

2002 - L

2003 - M

2004 - N

2005 - P

Hope this helps.

Trane seems to use confusing date codes as well.
