Goodman serial number date code

Common numeric Goodman HVAC serials · Sources checked October 12, 2026

For many Goodman heating and cooling products, the first four serial digits use YYMM: two digits for the year followed by two for the month. Read the equipment serial, not the serial on a replacement compressor.

A month must be between 01 and 12. Letters or a different arrangement can indicate another product family; do not force that serial into this numeric format.

Some packaged terminal air conditioners use another format. A manufacture date also differs from the installation date used for warranty coverage.

• Goodman manufacturer service agreement: manufacture-date convention

Use the format that belongs to this product family. A printed production date, a supported serial code or manufacturer confirmation can establish the age. Repeating year codes may leave more than one possible year; a model-series introduction date helps narrow the range but does not date your individual unit.

Heat Pumps typically last 10 to 15 years. Use, water quality and maintenance matter more than the brand. Clean indoor filters monthly in heavy use and keep snow and ice clear of the outdoor unit.

59 Goodman models are currently ENERGY STAR certified. The certified models went on the market between 2022 and 2026. An older Goodman heat pump may use more energy than today's certified models.
