Hello,
Seem to be having a hard time with this one:
Gibson
Model: gs3bd-o36k
Serial: gs3000151419
Can you help me with the manufacture date?
Thank you,
tom
36= 3 ton
30=30th week
00=2000
without going to the books my guess
Ditto
Thx!
What kept throwing me off, is that I thought the unit was from the 90’s(information about house). Client will be happier.

All of the units listed in my Prestons Guide are 1999 and 2000. Does anyone know if they manufactured furnaces during any other time frame??
