Comfort Systems USA (FIX) stock has surged nearly 46% year-to-date in 2026, becoming the latest industrial beneficiary of the AI data center and infrastructure build-out boom. This HVAC and plumbing installation company, highlighted by Epistrophy Capital's Cory Johnson, has transitioned from a niche player to a key infrastructure beneficiary. Johnson notes FIX's revenue now approaching 50% from technology-related services, up from under 5% five years ago, with growth doubling annually and consistently beating Wall Street estimates.

The company's ability to roll up contractors into its operations and expand margins quarter after quarter demonstrates its unique position in the AI-driven construction boom. FIX's rapid project completion cycles and S&P 500 entry further underscore the tangible demand for traditional infrastructure supporting the digital revolution.
