What’s on the rating plate?

Spaces and dashes are accepted. Check O/0 and I/1, and keep any leading zeros.

Checks ENERGY STAR model records and searches manuals separately from the serial. Certification records do not establish this unit’s manufacture date.

Known product context (optional)

Choose a system only when it matches the product family and its documentation. A purchase year or a manual’s publication date does not establish a manufacturing date.

Scope matters

Supported formats
and historical limits.

  • The local rule requires confirmation of a US unitary family covered by a YYMM warranty certificate. It does not apply to every global Daikin, ductless, VRV, chiller or applied-product serial.
  • The serial alone does not identify the full model, installation date or remaining warranty.

Research reviewed October 16, 2026. This independent tool applies published rules and retains unresolved years and model candidates.

Daikin US unitary ten-digit year/month system

Daikin US unitary HVAC equipment using the YYMM convention documented in2016 and2025 warranties

The first four digits encode two-digit manufacture year and month. Supported range starts with the manufacturer's2013 example, not an asserted introduction date. Six-digit suffixes in examples are illustrative, not a recovered customer record.

Confirm a Daikin US unitary system whose warranty certificate specifies a ten-digit YYMM serial; not an arbitrary ductless, VRV or applied-product serial.

Reading your result

Daikin lookup questions

Why does the year code match more than one year?

Some systems reuse letters or only encode the last one or two year digits. Every supported interpretation is retained. A decade supplied from reliable records can narrow the reading; the tool does not automatically pick the newest year.

Does the serial identify my exact model?

Usually the model is a separate plate field. Where published serial ranges actually identify a model, the result shows model candidates and links to their manuals. Overlapping ranges remain ambiguous.

Can I share the result?

After a lookup, the address includes the serial in a fragment beginning with #serial=. Use “Copy share link” to share the serial and selected context. Opening the link runs the same lookup. The fragment is not a query-string result page.
