Goodman Furnace

[Buck Hartley, CMI]

I can not find the date of MFR in my books. GMP-125-4, Serial # 0101614835. Looks newer that 1993.

Thanks!

January 2001


First two digits of the serial number are the year. Second two are the month of manufacture. Goodman started in 1975


I already had this information concerning Goodman furnace age.

Here is a great site to get information about HVAC equipment age.

Buck -

Are you using PrestonGuide OR the Carrier Bluebook??

My reason for asking is my Carrier Bluebook calls a Goodman GMP-125-4 a 1993, BUT my Info book on HVAC S/N's from C&D state that a S/N starting in 01 on a Goodman furnace is mfg in 2001.

Are you SURE of the Model # AND thats why we try and have several reference books at hand.

Dan,

I use the Preston's, Carrier and Dunlop. Preston's said 1993. The furnace is newer than, 1993.

Thanks!

1993 was probably the date the GMP-125-4 hit the market, but that specific unit was manufactured in January 2001.

It's like having a Ford Mustang. They started in 1964, but I have a 2007.
