What this business is made of
The business
Puts the equipment on the roof and charges for service for 20 years.
Trane Technologies makes climate control systems (HVAC — heating, ventilation and air conditioning) for commercial, residential and industrial buildings, plus transport refrigeration under the Thermo King brand. It sells the equipment and then charges for decades for service, parts and maintenance contracts. In 2025 it billed $21.3B with $2.8B of FCF.
The real business is in the installed base: once the equipment is on the building's roof, the owner comes back for service and parts for 15-20 years. Energy efficiency codes and the Trane brand create real switching costs. It's not a monopoly — it fights with Carrier, Daikin and Johnson Controls — but the recurring service gives it stability a pure manufacturer doesn't have.
Revenue history
From $14.1B to $21.3B in 4 years. The business grows steadily.
Where each $100 of sales goes
Revenue $21.3B · FY2025
Of every $100 in sales, $86 goes to costs and operations; $14 is left as net profit (14% margin).
Catalysts and risks
Demand for cooling for AI data centers, a segment growing at double digits annually.
Decarbonization and energy efficiency regulations in the U.S. and Europe forcing replacement of old equipment.
High commercial backlog that gives revenue visibility for 2026-2027.
Cyclical business: a drop in commercial construction hits new equipment directly.
Four large competitors with deep pockets limit pricing power.
$4.6B of debt against $1.8B of cash — manageable, but the cost rises in a high-rate environment.
Charlie's note
“A good boring business that collects a toll every time it's hot or cold. At 19.5x nothing is given away; you pay for quality at a fair price and wait for the recurring service to do the slow work.”

We do not calculate a value here: Trane Technologies does not generate cash flows you can project, and putting a number on it would be making it up. What you can do is follow it and tell us the price you care about — we will email you when it gets there.
