How old is my Frigidaire air conditioner?

Enter the serial number or take a photo of the label. The date comes from Frigidaire's documented serial rules; AI only helps read the label.

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

How to read a Frigidaire air conditioner serial number

  • Nordyne format on licensed brand names (about 1998 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 or the refrigerant line connections.

Don't open the unit's panels to look for it. If the plate is faded, the indoor coil or the installer's paperwork may also list the model and serial.

How long does a air conditioner last?

A typical air conditioner 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. Some manufacturer pages cite 15–20 years for well-maintained systems.

Do Nordyne, Intertherm, Miller, Broan, NuTone, Medallion, GrandAire, Garrison, Gibson, Kelvinator, Philco, Tappan, Westinghouse and Maytag air conditioners use the same serial format?
Yes. Frigidaire, Nordyne, Intertherm, Miller, Broan, NuTone, Medallion, GrandAire, Garrison, Gibson, Kelvinator, Philco, Tappan, Westinghouse and Maytag 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.
