    I was hoping that someone out there would be one of the proud owners of a Preston Guide? I guess I really need to order me one. I must say, I rarely have a problem in decoding the manufacturing date from the manufacturers data plate but this Lennox unit could go either way [1984 or 1999] and I too pride myself on a very comprehensive report which must include only the most accurate facts. This 4 ton unit is one of those combination heat pump / air handler systems.

    Anyway, the model number is: CHP26-048-2PA & the serial number is: 8499C24625

    Thank you in advance, hope your having a good spring. Things seem to be picking up here in this part of South Carolina.

    It appears that the unit you have was built in 1999. More recent Lennox products have the date coded where the first 2 digits of the SN are the manufacturing plant and the 2nd two digits are the year it was built. Your unit would appear to have been built in plant # 84, year 1999.

    One this new probably has a "mfd date" printed right on the info tag itself near the corner.

    that is correct----84 is the plant--99 the year and the C--is the month---months go A-M minus the I---so march of 1999

    Hi,

    Correct: Before 1974 the first 2 digiets indicated the year and the next digit the month. Example: 732xxx = February 1973.

    After 1973 the first two digits are the plant, the 3rd and 4th the year, and the 5th is a letter month (I omitted); therefore 8499C24625
    = March of 1999.
