Wild guess here... Goodman dealer? Goodman.com? Try a Google search on Goodman manuals, you will need the complete model and serial #`s for what you are looking for no matter where you go.
The model # indicates unit characteristics including capacity not the serial#. The serial # generally tells where , when , by whom and what components were used when it was made.
10 seer
According to the Goodman Mfg. website, this model is a 10 seer.
It would depend on the model of the Goodman unit.
