Tariffs and Tech: How Exposed Is Comfort Systems' Project Pipeline?

As tariff headlines rattle the construction and tech sectors, Comfort Systems USA FIX finds itself at the intersection of both. With 37% of its first-quarter 2025 revenue tied to advanced tech projects—including data centers and semiconductor fabs—the company’s exposure to trade policy uncertainty is real, especially as materials and equipment costs come under pressure.

Nonetheless, Comfort Systems management emphasized that most large project costs are locked in early, with pricing based on solid quotes from suppliers. The company also benefits from strong relationships with customers who are often willing to share inflation risks. So far, suppliers’ price hikes remain within typical ranges, and there’s no evidence of sticker shock or project delays stemming from the latest round of tariffs.

Comfort Systems’ scale, diversified backlog, and disciplined project selection help cushion macro shocks. A record $6.9 billion backlog, up 16% year over year on a same-store basis, reflects strong momentum, especially in tech and institutional markets. The company’s teams are already booking into 2026, with healthcare construction gaining ground as a new growth engine.

While management remains cautious and acknowledges the fluid macro environment, they see no letup in demand for mechanical and electrical contracting in complex builds. In the near term, tariffs may cause localized cost shifts, but Comfort Systems’ execution, margin discipline, and customer relationships appear strong enough to absorb the impact.

EMCOR and Limbach Face Similar Risks

Comfort Systems isn’t alone in navigating tariff-related uncertainty in tech-driven construction. EMCOR Group EME, a larger peer, also derives significant revenue from mechanical and electrical contracting across commercial, institutional, and industrial sectors. Like Comfort Systems, EMCOR is exposed to material cost inflation and relies heavily on pre-bid pricing to protect margins. Its size and diversified portfolio give it resilience, but tech project delays—especially in semiconductor and data center investments—could pressure growth.

Limbach Holdings LMB, a smaller competitor, is more narrowly focused on mechanical systems for institutional and healthcare clients. While its lower exposure to hyperscale tech may reduce tariff vulnerability, its tighter margins and smaller scale offer less flexibility to absorb cost shocks. Unlike Comfort Systems, LMB lacks the geographic breadth and backlog depth to hedge against rapid policy shifts. In contrast, Comfort Systems’ execution scale and customer diversity continue to give it a relative advantage amid an unpredictable tariff landscape.
