American Standard Furnace Age?

[Mike Lamb]

The ANSI date for this furnace was 1992 I think. I didn't write it down. The house was built in 2001. I checked my cheat sheet for American Standard and Trane and don't see anything that matches. SS# Z335W622G.

First letter, "Z" is 2001.

Yeah. In 2002, they switched to the first numeral, i.e., first digit 2 means 2002, 3 means 2003, etc.

I did look at the TIJ library for dates but missed that. Thanks. The 1992 ANSI threw me.
