Help dating an ADP air handler

[Robert Foster]

My usual sources don't explain ADP date codes. Can someone explain ADP's serial numbers to me. Here's the air handlers serial number.

6003C13358

I once needed help dating sisters, but never an air handler.;)

I would never admit I needed help with that! Were they twins?
Course, I would never date my sisters, but I'm not from Georgia.

Just a rough guess would be 2003.

ADP is a Lennox product. I'm pretty sure it's 03
