How old is my Nordyne equipment?

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

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

Nordyne built the furnaces, air conditioners and heat pumps sold as Intertherm, Miller, Frigidaire, Maytag, Gibson, Westinghouse, Broan and more, and Rheem bought its parent, Nortek Global HVAC, in October 2024. Their 12-character serials put the year in the 4th and 5th characters and the month in the 6th and 7th: Nordyne’s own warranty lookup lists B6D130407356 as made on April 10, 2013.

Questions

Does this cover mobile and manufactured home furnaces?
Yes, for Intertherm, Miller, Broan and Medallion units with the 12-character serial. Nordyne’s 2006 bulletin to manufactured-housing distributors refers to products with “serial date codes of 0602 and after”, which is February 2006 in this format.
Why isn’t my older Frigidaire, Westinghouse or Maytag serial decoded?
Those names were on other companies’ equipment before Nordyne made it: we decode Frigidaire, Westinghouse, Gibson, Kelvinator, Philco and Tappan from about 1998 and Maytag from 2002. Older styles, such as serials ending in a year and a month letter, have conflicting sources, so we leave them undecoded.
Is a plate marked “Manufactured for Nordyne” decoded the same way?
Not necessarily. Some early units were built by Rheem and carry Rheem’s serial format instead, so we don’t read them with the Nordyne rule.
How do I find the age of my Nordyne equipment?
Enter the serial number from the rating plate above. Nordyne uses the Nordyne / Nortek family serial format, which includes the manufacture date.

Rules last reviewed 2026-09-30. These rules are in Beta while we verify more real-world examples, so results are capped at medium confidence.

Manufacture dates are decoded from manufacturer serial-number conventions and available documentation. Serial formats can change. Verify critical equipment information with the manufacturer when necessary.
