How old is my Mitsubishi Electric Trane unit?

Mitsubishi Electric Trane is part of METUS JV. 2 serial formats sourced across mini split.

• Mitsubishi Electric Trane mini split serial numbers in the era not stated format encode the year as position 1 = last digit of Mitsubishi FISCAL year (Apr-Mar); decade must be assumed (89D... = 2008 or 2018) and the position 2 = month: 1-9 = Jan-Sep, X = Oct, Y = Nov, Z = Dec (can be a digit OR a letter) (source: building-center.org).
• Example: serial 89D00488D decodes to 1958 or 1968 or 1978 or 1988 or 1998 or 2008 or 2018 (September).
• The era not stated format is ambiguous: Single year digit repeats every decade. Fiscal year runs April-March, so units built Jan-Mar carry the PREVIOUS year's digit (building-center example: plate date Jan 2006, serial year digit 5). Example 8XD00488D = Oct 2008/2018.
