How old is my MrCool mini split?
Serial number age decoder for MrCool mini splits: 1 format era, the decode rule in plain English, transcribed tables, and the official lookup.
Type the serial from the data plate, not the model number. Nothing is sent anywhere; the tables are in this page.
Format example: 2402135890267230130069
- MrCool mini split 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.
- MrCool's official lookup at mrcool.com returns warranty / registration lookup.

Where the data plate is on a mini split
Two plates: one on the side of the outdoor unit, one on the indoor head (lift the front cover or look under the unit). The two serials differ; decode the outdoor unit for the system age.
General guidance, not brand-specific: the owner's manual or the installer can point to the exact spot. See the data plate guide.

What we could not confirm

Style 2: 22-digit Midea barcode serial, positions 12-15 = Y M DD ('SEE THE BAR CODE FOR THE PRODUCED DATE' is printed on the plate). mrcool.com/warranty-registration = 200 (registration).
