Luxaire Serial Number Lookup
Luxaire is part of the York / Johnson Controls family, alongside Coleman, Fraser-Johnston, Guardian, York. Enter the serial from the data plate below to get the manufacture date with a character-by-character explanation, the unit's age, its refrigerant era, and the warranty picture.
Decode schemes compiled from manufacturer literature and inspector references, cross-checked across two sources wherever possible (Luxaire sources: building-center.org + howtolookatahouse + pickhvac; pickhvac + howtolookatahouse + building-center.org). Single-sourced rules are labeled low confidence instead of being presented as fact. A date stamped or printed on the data plate always outranks a serial decode.
Luxaire Serial Number Formats
| Format | Era | Example | Confidence |
|---|---|---|---|
| Letter + digit + letter + digit + 6-digit sequence; the two digits read together are the year, the second letter is the month (A to N, skipping I and J) | October 2004 to present | W1G7123456 = July 2017, Wichita KS plant | high |
| 4 letters + 6 digits; second letter = month, third letter = year on a 21-year cycle | 1971 to October 2004 | YHFM321456 = August 1976 or August 1997 (year letter F repeats) | high |
Worked Example: Luxaire W1G7123456
Expected decode: July 2017, Wichita KS plant. Character by character:
W = plant code (Wichita KS)
1 and 7 = year digits read together: 2017
G = July (month letters A to N, I and J skipped)
123456 = production sequence
Luxaire Refrigerant Timeline
| Manufacture year | Typical refrigerant | Notes |
|---|---|---|
| through 2005 | R-22 | Standard refrigerant of the era. Production of new R-22 ended in 2020; supply is reclaim-only. |
| 2006 to 2009 | R-22 or R-410A | Overlap window as JCI lines transitioned to R-410A. |
| 2010 to 2024 | R-410A | EPA banned R-22 in new equipment from January 1, 2010; R-410A was the standard through 2024. Last R-410A manufacture December 31, 2024; split systems installable through December 31, 2025. |
| 2025 and later | R-454B | JCI chose R-454B for York, Luxaire, Coleman, Fraser-Johnston, and Guardian ducted residential, with production from 2024-2025 onward. |
The refrigerant printed on the nameplate is authoritative; this timeline tells you what is typical for the age, not what is in a specific unit.

Frequently Asked Questions
How old is my Luxaire unit?
Decode the serial number from the data plate. The dominant Luxaire format (October 2004 to present) is: Letter + digit + letter + digit + 6-digit sequence; the two digits read together are the year, the second letter is the month (A to N, skipping I and J). Example: W1G7123456 decodes to July 2017, Wichita KS plant. Subtract the decoded year from the current year for the age. Units past 15 years are replacement candidates, and past 20 a major repair rarely pays off.
Which brands share the Luxaire serial number format?
Luxaire is part of the York / Johnson Controls family, alongside Coleman, Fraser-Johnston, Guardian, and York. These brands come off shared production lines with the same data plates, so one decode rule dates all of them, and the refrigerant and warranty picture is the same across the family.
What refrigerant does a Luxaire unit use?
By manufacture year: through 2005: R-22; 2006 to 2009: R-22 or R-410A; 2010 to 2024: R-410A; 2025 and later: R-454B. The refrigerant printed on the nameplate is authoritative; the year-based mapping tells you what is typical for the age, not what is in a specific unit.
Is my Luxaire unit still under warranty?
Current policy: 10-year parts limited warranty registered within 90 days, 5-year parts unregistered, same structure across York, Luxaire, and Coleman, with compressor and heat-exchanger enhancements by line. Decode the manufacture date above, then confirm coverage by running the full serial through the manufacturer's own warranty lookup. Terms shown are the current policy; older units often carried different terms.
