Just called York. I have this model, however York needed the serial number to find the SEER. Can a model have more than one SEER? I doubt it. My SEER for this model is 13.
Model number of indoor and outdoor unit needed to compile SEER rating.
The SEER is 10 (http://www.ehow.com/how_7590098_do-number-tseries-air-conditioner.html )
SEER means Seasonal Effective Energy Rating.

The SEER rating on a York AC unit model TCGD 36S21S1s is a 13. The SEER rating stands for the seasonal energy efficiency ratio. The SEER ratio is something a person should look for when looking at AC units to purchase.
