About Comfort Systems USA, Inc.
About Comfort Systems USA, Inc.
Comfort Systems USA split 2025 revenue 73.3% from mechanical services and 26.7% from electrical services across 50 operating units in 142 U.S. cities, with the technology sector representing 45% of consolidated revenue—the single largest end-market. The project backlog stood at $11.94 billion at December 31, 2025, with 8,427 active projects averaging $2.9 million each. The workforce of 22,700 employees at year-end operated under only 9 collective bargaining agreements.
Comfort Systems earns revenue through project installation (63.2% of 2025 revenue) in newly constructed facilities and renovation, maintenance, repair, and replacement services (36.8%) in existing buildings. The technology end-market—data centers, semiconductor fabs, and advanced manufacturing—contributed 45% of 2025 revenue, followed by manufacturing at 22.1%, healthcare at 8.9%, and education at 7.3%. Raw materials and components, including ductwork, pipe, electrical wire, conduit, and fixtures, represent approximately 40% to 45% of average project cost; the company employs early purchasing and price-escalation contract clauses to manage commodity and tariff cost exposure. One customer represented 12.8% of consolidated 2025 revenue. The largest active contract at December 31, 2025 was priced at $496.9 million. The company competes against thousands of small owner-operated regional firms as well as larger divisions of utilities and MEP equipment manufacturers including Trane, Carrier, Schneider Electric, and Johnson Controls, among others.
Show full overview
The 45% revenue concentration in technology-sector customers exposes Comfort Systems to data center and semiconductor construction cycles that may not move in step with broader construction trends. The 10-K notes that results from economic downturns are felt well after the broader cycle begins, and that government projects (5% of 2025 revenue) could be affected by federal, state, or local budget reductions. Within the technology end-market, the largest single project in progress at year-end was priced at $496.9 million, concentrating execution risk in a single contract even as the broader portfolio spans thousands of smaller engagements.
