What Is A Goodman AC Unit Serial Number?
A serial number is a unique identifier assigned to every Goodman air conditioner during manufacturing. This combination of numbers and sometimes letters is essential for warranty verification, service history, recall notices, and confirming the production date.
The serial number is different from the model number. While the model number tells you the product type and features, the serial number reveals when and where the specific unit was made and sometimes other tracking information.
Where To Find The Serial Number On Goodman Air Conditioners
The Goodman serial number is found on the manufacturer’s data plate located on the outdoor condenser unit. For most residential Goodman AC systems, look for:
- A metallic data tag (nameplate) on the side or rear of the outdoor unit, near the electrical lines or refrigerant piping
- The serial and model numbers are typically printed together, with “Serial” or “Ser. No.” preceding the digits
- Sometimes, the information is also printed on a sticker inside the unit’s cabinet or near the compressor
For split system ACs, check the outdoor compressor/condenser, not the indoor evaporator coil.
Typical Goodman Serial Number Formats By Era
Goodman has used several serial number formats over the decades. Knowing the era your AC was made helps decode the number correctly.
| Manufacturing Period | Serial Number Example | How To Decode |
|---|---|---|
| Post-2000 | 0408135689 | First two digits: year (04 = 2004), next two: week (08 = 8th week) |
| 1990-1999 | 9604123456 | First two digits: year (96 = 1996), next two: week (04 = 4th week) |
| 1980s-Early 90s | 910112345 | First two digits: year (91 = 1991), next two: week (01 = 1st week) |
Some very old units or certain lines could have a slightly different structure, but the “year+week” pattern dominates modern Goodman systems.
Why The Serial Number Is Important
The Goodman AC unit serial number serves multiple crucial purposes:
- Determining Age: Know how old your system is for replacement or maintenance planning
- Warranty Verification: Warranty length is tied to production and installation date
- Model/Recall Info: Receive notifications or check eligibility for manufacturer actions
- Troubleshooting & Parts: Accurate serial info helps technicians order the right components
Recording the serial number after installation protects your investment and simplifies future service calls.

How To Decode A Goodman AC Serial Number
Step-By-Step Serial Number Decoding
Inspect your data plate and find the full 10-character serial number. Typically, the structure is:
- First two digits: Year of manufacture (e.g., 14 = 2014)
- Next two digits: Week of the year (e.g., 22 = 22nd week, late May)
- Remaining digits: Unique production sequence or manufacturing plant ID
So, for a serial number like 1422003456:
- 14: Year = 2014
- 22: Week = 22nd week
- 003456: Unit’s specific production batch
If the serial number does not match this pattern (e.g., older units), look for:
- First two digits as year (95 = 1995)
- Next two digits as week
Units made before the 1990s may require contacting Goodman for assistance, as formats were less consistent.
Sample Serial Number Breakdown Table
| Serial Number | Year | Week | Batch/Sequence |
|---|---|---|---|
| 1605432156 | 2016 | 05 | 432156 |
| 0710023456 | 2007 | 10 | 023456 |
| 9908123456 | 1999 | 08 | 123456 |
How To Use The Serial Number To Determine The Age Of Your Goodman AC
Age is key for maintenance scheduling, resale value, and warranty.
- Locate the serial number, using the data plate as above
- Take the first four digits: YYWW (Year, Week)
- Convert the “YY” to the full year (e.g., “04” means 2004, assuming a post-2000 model)
- The two “WW” digits tell which week of the year the unit was made (e.g., “08” is February)
If you see an odd sequence or cannot determine the pattern, consult the Goodman warranty department or your HVAC professional.
How The Serial Number Relates To Warranty & Service
Goodman typically provides a 5- or 10-year parts limited warranty on new residential units, starting from the installation or manufacture date. To confirm coverage and get full benefits, you need:
- The serial number (for the specific unit)
- Proof of purchase and installation date (installers often record this data, but the serial number is essential)
- Online registration: Homeowners are encouraged to register their Goodman units online using the serial number. This can extend warranty coverage
If you bought a home with an existing Goodman AC, look for the data plate and register your system if possible. Some warranties may transfer to new owners, but registration and the serial number are always required.

Different Serial Number Styles For Goodman, Amana, And Allied Brands
Goodman manufactures multiple HVAC brands, including Amana. Most use the same serial number format, but always check your device’s specific data plate. Other brands in the Goodman group (such as Daikin) might have different coding.
- Amana: Often uses the Goodman YYWW format after acquisition in the late 1990s
- Older brands: If in doubt, contact Goodman support to interpret your label
For warranty or parts, always provide the exact serial number as read, including any letters.
Troubleshooting Serial Number Problems
If you cannot find a serial number or it is illegible:
- Check all sides of the outdoor unit and inside service access panels
- Try cleaning the plate gently if it’s dirty or faded
- Ask your HVAC installer for a copy of installation documents (they often record numbers)
- If the plate is missing or destroyed, contact Goodman customer support with a photo of your unit and approximate age – they can sometimes assist via other unique identifiers
Never attempt to open sealed electrical components just to locate a number. All necessary info should be available on external plates or stickers.
Serial Number Vs. Model Number: What’s The Difference?
| Model Number | Serial Number |
|---|---|
| Indicates the product’s type, capacity, specs, features (e.g., GSX160361) | Unique identifier for your exact AC unit (e.g., 2010087654) |
| Good for sizing, replacement parts, and confirming product lines | Used for warranty, verifying production and service history |
Both numbers are usually on the same data plate. Always record both for homeowner records.
