HVAC Serial Number Lookup
Amana Serial Number Lookup
Amana is part of the Goodman family, alongside Goodman. 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 (Amana sources: building-center.org + inspectorhandbook + abihomeservices + 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 Most manufacturers do not publish serial nomenclature, so these rules rest on reference compilations rather than on a document from the company that built the unit.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.
Amana Serial Number Formats
| Format | Era | Example | Confidence |
|---|---|---|---|
| 10 digits; digits 1-2 = year, digits 3-4 = month | Goodman since at least 1997; Janitrol 1982-1992; Daikin US unitary 2013+ | 9704011000 = April 1997 | high |
Some older or conflicting Amana formats are recognized but deliberately not decoded; the decoder explains why when it sees one instead of guessing.
Worked Example: Amana 9704011000
Expected decode: April 1997. Character by character:
97 = year 1997 (digits 1-2)
04 = April (digits 3-4)
011000 = production sequence
Amana Refrigerant Timeline
| Manufacture year | Typical refrigerant | Notes |
|---|---|---|
| through 2009 | R-22 or R-410A | Goodman sold both in the 2000s: GSC-prefix models are R-22, GSX-prefix models are R-410A. Decode from the model letter, not the year alone. |
| 2010 to 2023 | R-410A | EPA banned R-22 in new equipment from January 1, 2010; R-410A was the standard through 2024. |
| 2024 | R-410A or R-32 | Goodman's R-32 lines (GLXS/GLZS prefixes) started production mid-2024 while R-410A production wound down. The model prefix decides. |
| 2025 and later | R-32 | Goodman and Amana chose R-32 (not R-454B) for the A2L transition under Daikin's R-32 commitment. |
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.
Amana Warranty Baseline
Current policy: 10-year parts limited warranty registered within 60 days of installation, 5-year parts unregistered. Select premium models registered add lifetime compressor limited warranty and/or 10-year unit replacement.

What the age tells you about coverage
Most manufacturers publish coverage in three age windows. Amana's own terms are the paragraph above, and where the two differ, that paragraph is the one sourced to Amana.
- 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. Amana'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 Amana unit?
Decode the serial number from the data plate. The dominant Amana format (since 1997, when Goodman took over Amana production) is: 10 digits; digits 1-2 = year, digits 3-4 = month. Example: 9704011000 decodes to April 1997. 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 Amana serial number format?
Amana is part of the Goodman family, alongside Goodman. 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 Amana unit use?
By manufacture year: through 2009: R-22 or R-410A; 2010 to 2023: R-410A; 2024: R-410A or R-32; 2025 and later: R-32. 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 Amana unit still under warranty?
Current policy: 10-year parts limited warranty registered within 60 days of installation, 5-year parts unregistered. Select premium models registered add lifetime compressor limited warranty and/or 10-year unit replacement. 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 Amana serial numbers refuse to decode?
This is the legacy Goodman format ending in P or D (PTAC and older units, retired shortly after the 2012 Daikin acquisition). Published sources conflict on which position is the year and which is the month, so this tool will not guess. Check the data plate or the installation paperwork.
