What’s on the rating plate?

Residential HVAC with matching WWYY + letter + five-digit sequence.

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.

  • Manufacture date is distinct from installation, purchase and warranty start dates.
  • The date code does not identify a full model, capacity or configuration. Enter the separate model from the rating plate for manual search.
  • Pre-1988 formats need an authenticated manufacturer chart; they are not forced through the modern rule.

HVAC: production week, year and site

hvac

Ten-character WWYY + manufacturing-site letter + five-digit sequence. Manufacturer manuals from 2000 and later document the layout; the supported range is 1993 from the manufacturer enhanced-warranty serial range, not a claim that every1993 model adopted it. Manufacturing-site codes vary by product.

Reading your result

Bryant 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.
