Preston’s says nothing.
I assume cuz mine only goes to 2000.
These units are younger than that.
If you know the age, could you share with how you found it?
TRANE uses alpha codes in their serial numbers to determine year of manufacture. They started this in 1987 with the letter B and skipped a couple of letters during the years but here we go…
1987-B 1988-C 1989-D 1990-E 1991-F 1992-G
1993-H 1994-I 1995-J 1996-K 1997-L 1998-M
1999-P **** 2000-R 2001-S
In 2002 they started their serial numbers with the year it was built. In 2002 the first character of the serial number is 2, in 2003, 3 and so on.
Looks to me like a 2002.
BTW, I think it’s not a** Z** — it’s a 2.
You’re the man, Jae!
thanks again
