Serial number decoder for MrCool

Serial no.

Type the serial from the data plate, not the model number. Nothing is sent anywhere; the tables are in this page.

Format example: 1920K08283

MrCool air conditioner serial numbers in the era not stated format encode the year as digits 3-4 (YY) -> 2020 and the week as digits 1-2 -> week 19 (source: building-center.org).
Example: serial 1920K08283 decodes to week 19 of 2020.
MrCool air conditioner serial numbers in the 2010 to present format encode the year as position 12 = last digit of year, 2010s presumed (6 = 2016) and the month as position 13 (1-9, A = Oct, B = Nov, C = Dec); day as positions 14-15 (source: building-center.org).
Example: serial 2402135890267230130069 decodes to 2016 or 2026 (July).
The 2010 to present format is ambiguous: Decade presumed 2010s by the source; a 2020s unit would read the same. Second example 240253122046A200150045 = 6,A,20 = 20 Oct 2016. Conflicts with the Midea (YY at 12-13) and Senville (YY at 17-18) readings of the same 22-digit shape.
