Bill Kibbel Posted August 4, 2005 Report Share Posted August 4, 2005 Can somone please date this unit? I can't - I'm happily married and my wife is still attractive. This is what I have for Trane. The first letter of the serial number gives the year of manufacture: Z=01 R=00 P=99 N=98 M=97 L=96 K=95 J=94 H=93 G=92 F=91 E=90 D=89 C=88 B=87 S=86 Y=85 X=84 W=83 U=82(seventh digit) T=81(seventh digit) O,A=80(seventh digit) Quote Link to comment Share on other sites More sharing options...
Chad Fabry Posted August 4, 2005 Author Report Share Posted August 4, 2005 Thanks very much. It looked old because it is. An air source heat pump in upstate NY is only effective when it's been installed in a price protected village where electricity is still 3 cents a KWH. Even at 3 cents, the bills were 250 a month for a 2,000 square foot home. Quote Link to comment Share on other sites More sharing options...
