    Default Age and size of unit

    First of all I will admit that HVAC is the system I know the least about. That said I need help with the age of this unit and I have no clue where to start. I am guessing this is a 3 ton unit based on skimming the HVAC threads here.

    This is a York unit.

    I just never understood the ignorance of manufacturers coding the age of systems.

    Why go to a convoluted system like creating charts to figure or decode the age.

    How about a big freaking stamp with a manufactured date on it.

    Look at the RUDD water heater below. How much more simple could it be.

    I'm with you on this Ted. The letter codes make no sense. Rudd units are very straightforward. I don't know why manufacturers insist on making it so difficult.

    At least Weil McClain has a CP Lookup Number page on their website where you can type in the CP# to get the age of their boilers. But that too is entirely avoidable.

    IIRC its three letters (plant, month, year) followed by six digits for pre 04 units.

    Serial # I see is (S)NFLM057215 so it would go by "L", correct?

    That's it Fritz, first pic flash was on which shows the SN clearly.

    This is the part that makes no sense and why I agree with Ted and Nick.

    Then why not post the first one?

    Yep 3rd place is year code, couldn't see the "N". Don't know HOW FK could SEE IT in the pic you posted.

    later models (04+) 2nd & 4th digit are numbers for year.

    Because I thought the information needed was in all of the other number/codes on the label, which you couldn't read because of the flash, but now I know.

    Young eyes? I wasn't sure either, glad my photography skills are lacking otherwise I wouldn't have the first pic.

    Actually you can hold the control button down and and press the plus key as many times as you wish to enlarge the picture

    Open up a picture, hold ctrl key down, hit the plus key

    Yes, I know this. I did this.

    For whatever reason that doesn't work for me.
    Might be something to do with my local settings or forum preference settings. Often when I first post despite what was composed, all the formatting disappears (if I forget to "preview" first, I miss this). I think I know I have some sort of a problem/conflict/debug issue with the first script that runs everytime a page is first or re-navigated here on the forum.

    I d/l'd and blew up, just couldn't make out what was obscured by the deep shadow, and not enough of the bottom of the characters to determine what they were. This is why I was so impressed with F.Z.'s determination! Perhaps I should have played around with resolution or screen settings, it might not have helped me - aging eyes and all. My photo-shop type skills are very limited.

    Obviously the second picture posted shows the Serial Number clearly.
