How to read the serial
era not stated formatUNSOURCED
Documented but not evaluated by the decoder: no pattern (no date encoded, or format unknown).
Trap: Manufacturer confirms a date is encoded but publishes no decode. Probably Midea-style; unverified.
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.
Official lookup: the authority

This site is a reference built from published tables. The manufacturer's own lookup wins whenever the two disagree.
What we could not confirm
- The era not stated format has no source we could check; it is shown for completeness only.
- The era not stated format is documented but not decodable here: no pattern (no date encoded, or format unknown).
- No building-center page (404 for /pioneer/, /pioneer-hvac/, /pioneer-hvac-age/). Pioneer's warranty page (200) states the warranty start 'cannot exceed ... 12 months following the manufacturing date of the Product as coded in the serial number' but does not publish the code. Likely the Midea 22-digit barcode style (see MrCool) - ESTIMATE, unsourced.
