The company's gross profit also rose to $2.20 billion, up 48.7% from the previous year's $1.48 billion.

The company’s operating income increased to $1.31 billion, representing a 75.5% rise from $749.4 million in 2024. The net income for 2025 was reported at $1.02 billion, compared to $522.4 million in the prior year, reflecting a substantial improvement in profitability. The increase in revenue and profit margins was attributed to enhanced operational execution and a growing backlog, which reached $11.94 billion, nearly doubling from $5.99 billion in 2024.
Comfort Systems expanded its operational footprint, increasing its number of operating locations from 47 to 50 through acquisitions and consolidations. The company reported a total of 8,427 projects in progress with an aggregate contract value of approximately $24.17 billion, with an average project size of $2.9 million. The mechanical segment accounted for 73.3% of total revenue, while the electrical segment contributed 26.7%. The company also noted a significant increase in customer engagement, particularly in the technology and manufacturing sectors, which drove demand for its services.
In terms of strategic initiatives, Comfort Systems emphasized its focus on sustainability and technological advancements, including investments in modular and off-site construction capabilities. The company aims to enhance its service offerings and operational efficiencies through ongoing training and development of its workforce. Looking ahead, Comfort Systems anticipates continued high demand in 2026, particularly from industrial and technology customers, despite potential economic challenges such as inflation and supply chain disruptions.
The company maintained a strong liquidity position, with $981.9 million in cash and cash equivalents as of December 31, 2025, and a revolving credit facility of $1.10 billion, of which $921 million remained available for borrowing. Comfort Systems has consistently generated positive free cash flow, totaling $1.04 billion in 2025, which supports its growth strategy and operational needs. The outlook remains optimistic, with expectations of solid earnings driven by a robust pipeline of opportunities and a strong backlog.
