Therma: The $466M HVAC Giant Hiding in Plain Sight

Why this 50-year-old mechanical contractor dominates California's industrial landscape

While tech startups chase unicorn valuations, Therma quietly commands $466.5M in annual revenue by solving the unsexy but critical problem of keeping California's industrial facilities running. This isn't a SaaS platform—it's a 1,149-person mechanical engineering powerhouse that's been profitable since before most founders were born.

"In an era of digital disruption, Therma proves that deep engineering expertise and client relationships create moats that algorithms can't touch."

The Industrial Infrastructure Playbook

Therma's 50-year run as California's leading commercial HVAC contractor reveals a counterintuitive truth: the most defensible businesses often aren't the flashiest. With 63% direct traffic and 31% organic search, their digital footprint is modest, but their client relationships run deep. They're not chasing SEO rankings—they're maintaining critical systems for hospitals, data centers, and manufacturing facilities where downtime costs millions. The top search term 'therma' (3,060 monthly searches) isn't even a keyword play—it's brand recognition from decades of reliable service.

The Hidden Growth Engine

While their traffic numbers seem modest compared to consumer tech, Therma's 31,008 monthly visits represent high-intent industrial buyers. The search data reveals sophisticated engineering queries: 'cooling capacity of a closed loop chilled water system' (140 monthly volume) and 'ducting start to condense when ceiling is installed' (280 monthly volume). These aren't casual browsers—they're facility managers and engineers solving complex problems. The 63% direct traffic is particularly telling: when your HVAC system fails at 2 AM, you don't Google—you call Therma directly.

The leadership team tells the story of operational excellence. Scott Carstairs (EVP Fabrication), Francis Wong (EVP Finance), and Jack Brunner (Director SoCal Process Piping) represent a blend of engineering and financial discipline that's rare in heavy industry. With 19 technologies detected in their stack—from jQuery to Zendesk—they're not Luddites, but they're also not distracted by the latest tech trends. Their tech stack serves the business, not the other way around.
