How do I verify when my Trane equipment was manufactured? The first letter of the serial number gives the year of manufacture as follows:

                9=2009
                8=2008
                7=2007
                6=2006
                5=2005
                4=2004
                3=2003
                2=2002
                Z=2001
                R=2000
                P=1999
                N=1998
                M=97
                L=96
                K=95
                J=94
                H=93
                G=92
                F=91
                E=90
                D=89
