How to decode a Goodman serial number

Supported Goodman HVAC serial decoding commonly uses the first two digits for year and the next two digits for month. That makes Goodman one of the clearer HVAC date paths on the site.

What the model number can tell you

The Goodman model number helps confirm equipment family, tonnage, and replacement class. It is useful for downstream replacement research even when the serial result itself is relatively direct.

Goodman is stronger than many HVAC brands because the supported serial structure can resolve to a more direct year/month reading.

Full serial required

Capture the full serial anyway because the complete label still helps with replacement and claim documentation.
