How old is my Maytag heat pump?
Enter the serial number or take a photo of the label. The date comes from Maytag's documented serial rules; AI only helps read the label.
How to read a Maytag heat pump serial number
Nordyne format on Maytag HVAC (2002 onward)
Not decoded yet: Rheem-built plates marked "Manufactured for Nordyne", older Frigidaire/Philco/Westinghouse serials ending in a year and month letter, 1970s Westinghouse serials, Mammoth and Reznor commercial units, and anything before these brands used the Nordyne format.
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.
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.

- Do Nordyne, Intertherm, Miller, Broan, NuTone, Medallion, GrandAire, Garrison, Frigidaire, Gibson, Kelvinator, Philco, Tappan and Westinghouse heat pumps use the same serial format?
- Yes. Maytag, Nordyne, Intertherm, Miller, Broan, NuTone, Medallion, GrandAire, Garrison, Frigidaire, Gibson, Kelvinator, Philco, Tappan and Westinghouse use the same serial-number conventions (Nordyne / Nortek family), so the same decoding rules apply.
- How reliable is the result?
- The Nordyne / Nortek 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.
