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.
