Anyone familiar with dating Armstrong HVAC products (I believe they are a division of Lennox) although the dating codes don't seem to follow Lennox's strange standards!

Unit is an "through the wall" package system in a one bedroom hotel/condo conversion, gas fired.

Model: 64HWC182-2

Serial: A-10573JNA

Ansi number of 1990

Thank You

October 1992. The last set of letters in serial number indicate the following in order: First letter - month, Second letter - year, Third letter - place of manufacture. Date Code, letter "J" corresponds to October. Year code, letter "N" corresponds to 1992

Hank, thank you...I just sent out the report saying " from the ANSI provided I would estimate system dates from the mid nineties" Seller told my client HVAC was replaced in 05...did not believe it either, hence the post.
