Comfort Systems USA, Inc. FIX is steadily expanding its exposure to data center construction, which is emerging as a meaningful driver of its accelerating growth profile. While the company continues to see healthy demand across manufacturing end markets, management indicated that, in many cases, data center opportunities are proving more compelling. This shift reflects the growing strength of demand in the technology sector, where large-scale data center projects are increasingly underpinning bookings and revenue growth.
Technology-related projects, including data center construction, accounted for approximately 42% of total revenues in the first nine months of 2025, up sharply from 32% in the prior year. This mix shift aligns with broader global trends, as demand for data centers continues to surge, driven by the rapid adoption of artificial intelligence, cloud computing, big data and digital services. The resulting investment cycle has triggered a construction boom across major markets, with hyperscale cloud providers leading capacity expansion and, in some regions, straining power and skilled labor availability.
The durability of this demand is further reflected in Comfort Systems’ backlog, which reached a record $9.4 billion at the end of the third quarter. Management highlighted that bookings during the quarter were particularly strong in the technology sector, spanning both traditional construction and modular offerings. Notably, executives emphasized that the data center pipeline remains robust, with no evidence of near-term moderation in bidding activity or customer demand.
Taken together, Comfort Systems’ growing exposure to data center construction appears well-positioned to serve as a sustainable growth engine, supporting elevated backlog visibility and reinforcing the company’s long-term earnings trajectory.
Competitors Expanding in Technology-Driven Markets
Several peers are also increasing their focus on technology-related construction, like data centers and services, creating a more competitive landscape for Comfort Systems. Sterling Infrastructure, Inc. STRL and Quanta Services, Inc. PWR are two major competitors operating in similar markets.
Sterling continues to strengthen its presence in large-scale, mission-critical site development. In the third quarter of 2025, data center revenues surged 125% year over year, underscoring strong demand for complex, high-capacity facilities. Sterling's E-Infrastructure Solutions segment remains the primary growth driver, supported by solid execution, robust project flow and a healthy pipeline.
Quanta is a relevant peer with significant exposure to electrical infrastructure and high-demand end markets. Similar to Comfort Systems, Quanta is benefiting from secular tailwinds tied to AI, data centers, electrification, grid modernization and power generation investment. Management has highlighted accelerating demand in its Electric segment and broad-based activity across key end markets, reinforcing project momentum and the durability of technology- and power-driven infrastructure spending.
