Bryant Serial Number Lookup
Bryant is part of the Carrier family, alongside Carrier, Payne. Enter the serial from the data plate below to get the manufacture date with a character-by-character explanation, the unit's age, its refrigerant era, and the warranty picture.
Decode schemes compiled from home-inspection and parts references, cross-checked across two sources wherever possible (Bryant sources: building-center.org + pickhvac + inspectorhandbook; building-center.org Carrier + Bryant + Day & Night pages; building-center.org (month letter table single-sourced; year digit is solid); building-center.org + pickhvac). Most manufacturers do not publish serial nomenclature, so these rules rest on reference compilations rather than on a document from the company that built the unit. Single-sourced rules are labeled low confidence instead of being presented as fact. A date stamped or printed on the data plate always outranks a serial decode.
Bryant Serial Number Formats
| Format | Era | Example | Confidence |
|---|---|---|---|
| 4 digits + letter + 4-6 digits; digits 1-2 = week, digits 3-4 = year, the letter is a plant code | ~1980 to present | 4006A17330 = week 40 of 2006 | high |
| 9-10 digits, no letters; digits 1-2 = year, digits 3-4 = month | 1980s (BDP-built units) | 850304091 = March 1985 | medium |
| 8 characters; US units start month letter (M-Z, skipping O and U) then year digit 0-4, Canadian units reverse the first two | 1980 to 1984 | W4D14008 = September 1984 | low |
| Letter A-L + year digit + 5-6 digit sequence; A = January through L = December | 1969 to 1979 | A167890 = January 1971 | medium |
Some older or conflicting Bryant formats are recognized but deliberately not decoded; the decoder explains why when it sees one instead of guessing.
Worked Example: Bryant 0709G10932
Expected decode: week 7 of 2009 (Bryant). Character by character:
07 = week 7 of the year (digits 1-2)
09 = year 2009 (digits 3-4)
G = plant/assembly code, 10932 = production sequence
Carrier-family serials are week-first. ICP brands (Heil, Tempstar) use the same visual layout with year first; the brand on the nameplate decides which reading applies.
Bryant Refrigerant Timeline
| Manufacture year | Typical refrigerant | Notes |
|---|---|---|
| through 1995 | R-22 | Standard refrigerant of the era. Production of new R-22 ended in 2020; supply is reclaim-only. |
| 1996 to 2009 | R-22 or R-410A (Puron) | Carrier launched Puron (R-410A) in 1996, the first residential R-410A line, so units in this window can be either. The model series on the data plate is the reliable signal, not the year. |
| 2010 to 2024 | R-410A | EPA banned R-22 in new equipment from January 1, 2010; R-410A was the standard through 2024. |
| 2025 and later | R-454B (Puron Advance) | EPA's AIM Act GWP limit applies to residential systems manufactured on or after January 1, 2025. R-410A units built earlier could still be installed during the sell-through window, so check the data plate on 2024-25 builds. |
The refrigerant printed on the nameplate is authoritative; this timeline tells you what is typical for the age, not what is in a specific unit.
Bryant Warranty Baseline
Current Carrier family policy: 10-year parts limited warranty when registered within 90 days of installation, 5-year parts unregistered. Bryant terms are inferred from the shared corporate template; confirm brand-specific terms on bryant.com. Pre-2010 units commonly carried 5-year parts / 10-year compressor instead.

What the age tells you about coverage
Most manufacturers publish coverage in three age windows. Bryant's own terms are the paragraph above, and where the two differ, that paragraph is the one sourced to Bryant.
- 5 years or newer
- This unit is likely still inside even the unregistered parts window. Run the serial through the manufacturer's warranty lookup before paying for parts.
- 6 to 10 years
- This unit is past the typical unregistered 5-year window but may still be inside a registered 10-year parts window. Whether the original owner registered it decides; the manufacturer's warranty lookup will say.
- 11 years or older
- This unit is at or beyond most registered parts windows (a few premium lines, such as Daikin, run 12 years). Terms shown are the manufacturer's current policy; older units often carried different terms.
These are the windows most manufacturers publish, and not all of them do. Bryant's own baseline above governs, and neither is a coverage decision on a specific unit. Registration status and the terms in force when the unit was sold both change the answer, and only the manufacturer's own lookup settles it.
Frequently Asked Questions
How old is my Bryant unit?
Decode the serial number from the data plate. The dominant Bryant format (~1980 to present) is: 4 digits + letter + 4-6 digits; digits 1-2 = week, digits 3-4 = year, the letter is a plant code. Example: 0709G10932 decodes to week 7 of 2009 (Bryant). Subtract the decoded year from the current year for the age. Units past 15 years are replacement candidates, and past 20 a major repair rarely pays off.
Which brands share the Bryant serial number format?
Bryant is part of the Carrier family, alongside Carrier and Payne. These brands come off shared production lines with the same data plates, so one decode rule dates all of them, and the refrigerant and warranty picture is the same across the family.
What refrigerant does a Bryant unit use?
By manufacture year: through 1995: R-22; 1996 to 2009: R-22 or R-410A (Puron); 2010 to 2024: R-410A; 2025 and later: R-454B (Puron Advance). The refrigerant printed on the nameplate is authoritative; the year-based mapping tells you what is typical for the age, not what is in a specific unit.
Is my Bryant unit still under warranty?
Current Carrier family policy: 10-year parts limited warranty when registered within 90 days of installation, 5-year parts unregistered. Bryant terms are inferred from the shared corporate template; confirm brand-specific terms on bryant.com. Pre-2010 units commonly carried 5-year parts / 10-year compressor instead. Decode the manufacture date above, then confirm coverage by running the full serial through the manufacturer's own warranty lookup. Terms shown are the current policy; older units often carried different terms.
Why do some Bryant serial numbers refuse to decode?
This matches the 1960-1979 Bryant/Carrier style (week digits + a year letter). The year-letter chart is documented by only one source and the unit would be 45+ years old, so this tool does not decode it. A unit that age is far past service life.
