Trane adds 10,000 jobs in 5 years as growth accelerates

Trane Technologies (NYSE:TT | TT Price Prediction) CEO Dave Regnery made a point recently that deserves more attention than it typically gets in earnings recaps: “Five years ago when we started as Trane Technologies we had 35,000 employees. Today we have over 45,000 employees. Growth companies create job opportunities.”

That’s 10,000 net new jobs in five years, and it’s not the result of an acquisition binge or a government mandate. It’s what happens when a company finds itself sitting at the intersection of two of the most powerful secular trends in the industrial world: decarbonization and the data economy.

The Building Efficiency Opportunity

Regnery’s pitch to investors starts with a number that reframes how you think about the entire HVAC industry. Buildings globally account for 30% of all energy consumption, and heating and cooling alone accounts for 40% of a building’s energy use. The kicker: most buildings operate approximately 30% inefficiently, which Regnery calls a “very conservative number.”

That inefficiency is the addressable market. Trane has built algorithms that make buildings smarter and more energy efficient, essentially turning legacy infrastructure into optimized systems without tearing walls down. Every inefficient commercial building is a potential customer.

The financial results back the thesis. Full-year 2025 revenue came in at $21.32 billion, up 7.48% year-over-year, with operating income growing 13.35% to $3.97 billion. Since the 2020 launch, Trane has compounded adjusted EPS at 24% annually while expanding EBITDA margins by 470 basis points.

The backlog tells you where this is headed. Trane ended 2025 with a record $7.80 billion enterprise backlog, up 15% from year-end 2024. Americas commercial HVAC applied bookings were up more than 120% in Q4, with a book-to-bill ratio of 200%. That means for every dollar of revenue shipped, two dollars of new orders came in.

Building the Workforce to Match

The hiring story isn’t just about headcount. Regnery noted that service technicians were among the hardest roles to fill during COVID, so Trane built a solution from within. The company developed an apprenticeship program now backed by the U.S. Department of Labor, with approximately 400 employees currently enrolled. The program runs two to four years depending on experience and recruits directly from Trane’s existing hourly workforce.

That’s a company investing in human capital the same way it invests in R&D: with a long time horizon and a specific return in mind.

For investors, the workforce growth number is a useful signal. Companies that are genuinely winning in large markets have to hire. Analysts have a consensus target of $479.73 on TT, and with 2026 adjusted EPS guidance of $14.65 to $14.85 and a record backlog providing revenue visibility well into 2027, Regnery’s confidence in “differentiated results” is grounded in something real: a business growing fast enough that it needs 10,000 more people to keep up.
