HVAC Serial Number Lookup

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.

Quick answer: Luxaire serial numbers (October 2004 to present): 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 = July 2017, Wichita KS plant. The same rule covers York, Coleman, Fraser-Johnston, and Guardian.

Decode schemes compiled from home-inspection and parts references, cross-checked across two sources wherever possible (Luxaire sources: building-center.org + howtolookatahouse + pickhvac; pickhvac + howtolookatahouse + building-center.org). Most manufacturers do not publish serial nomenclature, so these rules rest on reference compilations rather than on a document from the company that built the unit. 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.

Expected decode: July 2017, Wichita KS plant. Character by character:

July 2017

W = plant code (Wichita KS)

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.


Luxaire Warranty Baseline

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.

What the age tells you about coverage

Most manufacturers publish coverage in three age windows. Luxaire's own terms are the paragraph above, and where the two differ, that paragraph is the one sourced to Luxaire.

5 years or newer
This unit is likely still inside even the unregistered parts window. Run the serial through the manufacturer's warranty lookup before paying for parts.
6 to 10 years
This unit is past the typical unregistered 5-year window but may still be inside a registered 10-year parts window. Whether the original owner registered it decides; the manufacturer's warranty lookup will say.
11 years or older
This unit is at or beyond most registered parts windows (a few premium lines, such as Daikin, run 12 years). Terms shown are the manufacturer's current policy; older units often carried different terms.

These are the windows most manufacturers publish, and not all of them do. Luxaire's own baseline above governs, and neither is a coverage decision on a specific unit. Registration status and the terms in force when the unit was sold both change the answer, and only the manufacturer's own lookup settles it.


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.
