Need age on Heil Compressor

Serial Number : L011490544
Model Number : NACO48AKAA1

Compressor or condensor?

Or, maybe condensing unit, which would include both the compressor and the condenser?

I’m not finding that particular model in my Heil list, but some other low-end Heil units are listed under their minor brands Whilrpool and Tempstar. I show that unit under Tempstar from 2000-2004.

L01 should be a 2001 unit 4 tons

James has it. It is 2001.
