Electrical and Data Center Demand Power Comfort Systems' (FIX) Standout Quarter

Comfort Systems USA, Inc. (NYSE:FIX) is included among the 20 Best Performing Dividend Stocks in 2025.

Comfort Systems USA, Inc. (NYSE:FIX)'s third quarter stood out in a way that is hard to miss. Same-store revenue rose 33%. Margins moved higher. Earnings per share more than doubled from a year ago. Free cash flow for the quarter came in above $500 million, a level that reshapes expectations for the business.

CFO William George said revenue reached $2.5 billion, an increase of $639 million from last year. The electric segment drove much of that growth, with revenue up 71%, while mechanical revenue climbed 26%. He also noted that the company crossed an important milestone, generating more than $400 million in quarterly EBITDA for the first time. That figure was up 74% from the same quarter a year earlier.

The results reflect where the company has been focusing its efforts. Comfort Systems USA, Inc. (NYSE:FIX) works across mechanical, electrical, and plumbing services for commercial, institutional, and industrial customers. Its scope runs from designing and installing HVAC systems to maintenance work, electrical projects, and modular or off-site construction. Many of its projects involve large data centers, hospitals, schools, and manufacturing plants.

Over the past few years, management has emphasized a small number of priorities and stayed consistent. Operational execution remains a core focus. Building and keeping a skilled workforce has become just as critical. The company continues to adopt new construction methods, including modular building, to improve efficiency on complex projects.

Growth has also come from diversification. Comfort Systems USA, Inc. (NYSE:FIX) has expanded its exposure to faster-growing end markets like advanced technology and healthcare. Acquisitions remain part of the playbook, but they are approached with discipline, aimed at adding capabilities and reach without sacrificing margins or control.
