How old is my Goodman heat pump?

Enter the serial number from the label. The date comes from Goodman's documented serial rules, not a guess.

Look for “Serial No.” or “S/N” on the label. Spaces and dashes are fine.

How to read a Goodman heat pump serial number

Goodman, Amana and Daikin ducted systems made in Houston use an all-numeric serial: the first two digits are the year and the next two the month.

  • Year + month (all-numeric)

    Example: 0107415182 (Goodman) was made in July 2001. Goodman, Amana and Daikin ducted serials start with the year and month: "01" is 2001 and "07" is July.

Not decoded yet: Daikin ductless and VRV units don't encode the date in the serial; use the MFG. DATE on the plate. Older dashed Amana serials are not decoded.

Where to find the serial number

The rating plate is on the outdoor unit, usually on the side or back of the cabinet near the electrical disconnect.

The indoor air handler has its own plate and its own serial number, so check which unit you're decoding.

Goodman heat pump model numbers

If the brand name isn't visible on the label, the model number can help. Model numbers like these follow Goodman's published nomenclature:

How long does a heat pump last?

A typical heat pump lasts about 10–15 years. That's a general estimate: maintenance, usage, climate and installation all matter, and age alone doesn't tell you a unit's condition.

Questions

How can I tell how old my Goodman heat pump is?
Find the serial number on the rating plate and enter it above. Goodman heat pumps use the Daikin / Goodman family serial format, which includes the manufacture date. For example, 0107415182 was made in July 2001: Goodman, Amana and Daikin ducted serials start with the year and month: "01" is 2001 and "07" is July.
Where is the serial number on a Goodman heat pump?
The rating plate is on the outdoor unit, usually on the side or back of the cabinet near the electrical disconnect. The indoor air handler has its own plate and its own serial number, so check which unit you're decoding.
How long does a heat pump usually last?
A typical service life is about 10–15 years. That's a general estimate: maintenance, usage, climate and installation all matter, and age alone doesn't tell you a unit's condition.
Do Amana and Daikin heat pumps use the same serial format?
Yes. Goodman, Amana and Daikin use the same serial-number conventions (Daikin / Goodman family), so the same decoding rules apply.
How reliable is the result?
The Daikin / Goodman family rules come from documented sources, but they're in Beta while we check more real-world examples, so results are capped at medium confidence. If a serial doesn't match a documented format, we say so instead of guessing.

Same serial format: Amana heat pump, Daikin heat pump

Other Goodman equipment: furnace, air conditioner
