I was wandering if there was a way to tell the seer rating and the production date on a goodman condensing unit.
The ser# 9510114597 and the model# CPKE36-1 I have to change out outdoor unit for customer and trying to make sure to get the right replacement. I know it is a 3 ton heatpump but trying to find out if this is a 10 seer or not. Thanks for any help you can give me.
