With Armstrong, if the serial number starts with four numerals, the second two indicate the year.

Both of your units were made in 2000.

Okay, I thought of that and although the furnace looks 10 years old, I still can't get it through my head that this is 2009, 2000 was 9 years ago... almost 10... sigh

Thanks Jim
