Some Wall Street analysts are treating Trane Technologies not as a manufacturing company whose fortunes rise and fall with commercial facility construction but as a technology company — a software-as-a-service company whose main source of income is recurring revenue from service subscriptions. 

That’s because so much of the company’s revenue — up to half in the case of its commercial HVAC business — comes from service contracts. For investors, this means the company is a good counter-cyclical bet: if facility construction is down, the company will still make money from the outsized importance of its service contracts. For facilities managers, it means they’re a beneficiary of a business model that’s built around keeping their systems operating optimally, industry specialists say.

“Trane’s real economic moat comes from the 50+ million connected devices and systems operating globally that require continuous service, parts replacement, software updates, and eventual full system upgrades,” the Wealth Dynasty Report says in an analysis in January. “The initial equipment sale is merely customer acquisition; the decades-long service relationship is where exceptional returns compound.”

All of the major manufacturers in the HVAC, chiller and building controls spaces rely on recurring revenue from their service contracts as a significant part of how they create value. The companies generally don’t break out in their earnings reports the percentage of revenue generated from services. However, one analysis shows Carrier’s aftermarket business, which includes parts and service contracts, at about 23% in fiscal year 2022. An analysis of Johnson Controls by Krause Fund Research, which is associated with the University of Iowa, shows that the company generated about 26% of its revenue from the contracts in fiscal year 2024.  

For Trane, more than 40% of its revenue comes from the contracts — which generate margins of more than 30%, according to the Wealth Dynasty report.

“There is certainly a difference between Trane and peers in terms of the revenue mix and how much services make up as part of that,” Noah Kaye, managing director and senior analyst at stock brokerage Oppenheimer, said in an interview. “It is ultimately higher for Trane versus Johnson Controls versus Carrier.”

One reason the service contract portion of its business is high stems from its in-house approach, Kaye said. 

“They have the largest direct sales force in the industry,” Kaye said. They “figure out what solutions are going to make sense [and] the services portion of that has always provided the long tail.”

The Wealth Dynasty report calls Trane’s in-house services one of its strategic advantages in the commercial HVAC, chiller and building controls spaces. 

“Trane maintains approximately one certified technician per 180 installed systems — a ratio competitors struggle to match,” the report says. 

Strategic decision

The company started consolidating distribution and services in-house years ago, Andrew Disher, a product manager in Trane’s Smart Services division, said in an interview.   

After initially relying on independent distributors to bring its products to market, the company began moving toward the in-house model by acquiring distributors and consolidating their service work, he said.

“A lot of these [independent] franchise holders started to spin up service businesses,” Disher said. “At first a lot of them abdicated the service business to the mechanical contractor market. They were mostly interested in selling equipment. But then they said, ‘Hey, we can do service, too, and keep with the customer and maybe better serve them.’ So Trane over the years moved … to acquiring those companies and now we’re mostly direct distribution.”

A case in point is Trane’s 2027 decision to consolidate sales in Georgia and Tennessee within a single in-house Atlanta office. “The company decided to change its … distribution strategy in this territory from independent wholesale distribution to company-owned distribution,” Trane said in an announcement at the time. “We decided it was in the best interest of our business — and that of our dealers — to transition to company-owned distribution.”

Trane’s acquisition by industrial technologies giant Ingersoll-Rand in 2007 helped solidify the company’s strategy by giving it a platform to service its customers’ systems, according to the Wealth Dynasty report.   

The company initially used the platform for high-level consultative work, typically with energy efficiency goals in mind, Disher said. 

“We would get a team of energy engineers and other experts and deep dive into what’s going on and then sit down with a client and consult with them,” he said. “‘Hey, here’s the operational problems that are going on. Here’s your energy issues that are happening.’ And then we rack and stack projects.”

It has since expanded use of the platform for more mainstream servicing, he said. 

“Instead of a team of specialized, highly trained energy engineers that look for in-depth energy analysis, [we’re] now putting those same tools … into the hands of our chillers service mechanics and our control service technicians, so that they can use more efficient and better technology to do better outcomes,” he said.

The service relationship between Trane and its customers is two-way, Disher said. By logging into the platform, the customer can track how its systems are performing and reach out to the company if it sees some aspect of the systems trending in the wrong direction. Alternately, Trane might detect an issue and reach out to the customer. 

“It’s almost … like a constant conversation that we can have,” he said. “Maybe we’re on one of these scheduled service agreements [and we] go, ‘Hey, what are the analytics saying?’” Disher said. “‘This oil system is starting to get out of spec. It’s not failed. It’s not a problem yet. But it’s starting to trend that way. Let’s talk to the customer about that and see if we can resolve something proactively.’”

The latest cloud-based iteration of the platform enables the company to set up a system so that it sends an alert when a metric hits a trigger. “It’s going to alert people automatically and go, ‘Hey, you need to go look at this thing,’” Disher said. 

Building systems have been moving toward the connected servicing model for years, so what Trane is doing isn’t unique, but the platform it uses gives it a competitive advantage, according to the Wealth Dynasty report.

“Trane’s proprietary diagnostic software (acquired through the $14.9B acquisition of Ingersoll Rand’s Industrial segment) creates knowledge barriers — third-party service providers cannot access system data, effectively locking customers into Trane’s service ecosystem,” says the report, which highlights the company’s 92% service contract renewal rate.  

The Wealth Dynasty report estimates that for every $500,000 commercial HVAC system it sells, the company generates roughly $75,000 in equipment margin, $15,000 to $25,000 annually in service contracts for 15 to 25 years and $8,000 to $12,000 annually in parts and consumables. It also says there’s a 60% to 80% probability that within 20 years the customer will purchase a system upgrade.

“The mathematics are striking,” the report says. “The post-sale revenue from a single installation exceeds the initial equipment sale by 4-7x over the system lifecycle.”

The company can expect the next several years to be promising under this formula because the equipment it sold in a sales spurt starting about two dozen years ago is moving into a high-maintenance phase, the report says. 

“Trane’s installed base is aging asymmetrically,” it says. “Systems installed during the 2000-2010 commercial building boom are entering their high-maintenance years simultaneously, creating a predictable surge in service demand.”

Trane Technologies CEO Dave Regnery pointed to the strength of the company’s service model in the company’s fourth quarter 2025 earnings call in January.

“Our services business … remains a durable and consistent growth engine,” he said on the call. “We continue to invest heavily in services and expand our digital capabilities to deliver advanced solutions with compelling value and attractive paybacks. We are confident services will remain a strong growth driver in 2026 and beyond.”

Investors have taken note, according to a Simply Wall St. report from last month. “[Investors are reassessing] the HVAC group as a subscription style cash flow story,” the report says. “The recent focus on Trane’s subscription style economics has arrived alongside strong share price momentum.”

The report highlights the company’s five-year total shareholder return of 213.14%. 

“Trane Technologies has quietly perfected this transformation,” the Wealth Dynasty report says. It’s “hiding behind an industrial facade while operating economics that would command software-like valuations if properly understood.”
