I’m figuring the AC is 2002, but the format of the furnace S/N throws me a bit, because the unit looks older, but is quite clean upon inspection. Could be 2005.
Thanks in advance.
Prestons Guide says 2002 - 2005 on the AC.
The furnace serial number format looks like a York number which would make it 2003. The A/C is February 2006.
It’s not unusual to find larger companies like York manufacturing units for smaller companies like Coleman, and it runs about 50/50 as to what serial number format they’ll use when they do.
I date both units for 2002.
**See York Serial #'s at http://hisearch.org/York.aspx](http://hisearch.org/York.aspx) Shows that this unit was manufactured in October 2002.
**See Coleman Serial #'s at **http://hisearch.org/Coleman.aspx](http://hisearch.org/Coleman.aspx)
**Shows that this unit was manufactured in June 2002.
