What follows from the reading
Share of working time within reach of AI, on the long-run pace at four in five: 19% now, 30% at the end of 2027, 36% at the end of 2028, 38% at the end of 2030. By the patterns, the work is about 38% desk work, 16% people work and 47% body work. These are the site's industry estimates weighted by the shares below: estimates with a stated method and range, not a forecast of what the company will do. By the same patterns, at the end of 2028 about 62% of the working time stays with people (conversation, in-person and hands-on work), 30% becomes checking a model's work and 5% could be handed over with lighter checks, from the industries' own figures, not the company's roles.
Headcount
12,900 employees as of December 31, 2025 (stated). Approximately 8,500 of 12,900 employees in the U.S. (66%) and 3,200 in Mexico, stated.
The filing: “As of December 31, 2025, we employed approximately 12,900 people, primarily in the U.S. (approximately 8,500 employees) and Mexico (approximately 3,200 employees). Of these employees, approximately 5,400 were salaried and 7,500 were hourly.”
The workforce as industry patterns
| Pattern | Share | Reason, from the filing |
|---|---|---|
| Machinery Manufacturing (3331, 3332, 3334, and 3339 only) | 100% | The Residential (64% of revenue) and Commercial (36%) Heating and Cooling segments make furnaces, air conditioners, heat pumps and rooftop units in plants in the U.S. and Mexico, which NAICS counts with HVAC equipment (3334, in 3330A1), and the filing counts no employees by segment, so one pattern carries the whole workforce by description (c). |
What the filing says about the workforce: About 5,400 salaried and 7,500 hourly (58%); 8,500 in the U.S. and 3,200 in Mexico; about 3,400 union-represented (26%); higher turnover at manufacturing and distribution locations, as the filing states it.

Questions about this company
- How much of Lennox International Inc.'s working time is within reach of AI?
- An estimated 19% now and 36% by the end of 2028, on METR's long-run pace at four in five, from the workforce Lennox International Inc.'s own annual report describes and BLS staffing patterns for its industries, never from a roster. It is an estimate with a stated method. It is not a forecast of jobs lost or of savings, and it says nothing about what the company will do.
- How many people does Lennox International Inc. employ?
- 12,900 as of December 31, 2025, as its annual report for the period ending December 31, 2025 states. About 66% in the U.S.

Each share has a one-sentence reason on this page that can be checked against the filing.
- What does Lennox International Inc.'s annual report say about AI?
- 11 sentences in the filing name AI. Its annual reports for fiscal 2021 to 2025 name it in 0, 0, 0, 8 and 11 sentences, year by year. They are counted and quoted on this page, never judged: a count says how much a filing talks about AI, not what the company does with it.
- How is this estimated?
- Claude Fable 5.1 read the annual report under the Index's written rubric (version 1) on October 19, 2026: the stated headcount, the share in the U.S. when stated, and the workforce as a blend of industry staffing patterns. The estimates are the site's industry estimates weighted by those shares, from O*NET tasks with estimated lengths and METR's measurements of how long a task AI models can finish. A company can write to info@stratussc.com to have its reading checked against its filing.
