How old is my Gree mini split?

Serial number age decoder for Gree mini splits: 1 format era, the decode rule in plain English, transcribed tables, and the official lookup.

• Gree mini split serial numbers in the era not stated format encode the year as plate 'Date of Manufacture' field, 4-digit year and the month as 2 digits after the dot (source: building-center.org).
• Example: serial 2020.05 decodes to May 2020.
• Gree's official lookup at greecomfort.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

• Gree prints the build date on the data plate as YYYY.MM ('Date of Manufacture 2020.05'); building-center does not decode the serial itself. greecomfort.com/warranty-program/ = 200 and links a serial-number warranty search at /gree-warranty-registration-search. Gree also OEMs for many brands; Daikin-Gree JV (2008-09) units may use either company's style.
