Goodman Serial Number Decoder
How to decode Goodman and Amana serial numbers.
The serial number is critical for determining a unit's precise age and date of manufacture, something the model number will only hint at. Since Goodman purchased Amana in the nineties, the same methods for decoding serial numbers can be applied to both brands. Of these methods there are several, but, rather than hunt down the nomenclature for your specific style of serial number, you can simply let the HVAC Decoder App handle the different cases for you. The results from the built-in Goodman Serial Number Decoder are shown below. For this particular style, the first two digits indicate the year of manufacture, and the second two digits indicate the month. The decoder also displays the unit's age based on those two codes.
