From DFW Heat to AI Insight: Why We Built This Tool

From DFW Heat to AI Insight: Why We Built This Tool

Every company has an origin story. Ours began not in Silicon Valley, not in a sleek accelerator program, but in the sun-baked suburbs of Dallas–Fort Worth. We were just a small, regional HVAC company—Greentech DFW—with a big, familiar problem: people.

Not the customers. The customers were fine—hot, sweaty, frustrated, and desperate for working air conditioning in July (who could blame them?). The real challenge was technicians. Training new hires required months of investment—six, twelve, sometimes eighteen months. And even then, many quit. Not because they lacked skill, but because few people are willing to crawl through attics and wrestle compressors under the brutal Texas summer for long.

To become a competent HVAC installer or service tech? That’s a five-to-seven-year journey. Layer on tariffs, inflation, rising labor costs, and a customer base that—quite understandably—wants both premium service and reasonable pricing, and you get the perfect storm.

Somewhere in the noise, we caught a conversation on Reddit that stuck with us. A fellow tech joked:

“We don’t sell new units for the commission. We sell them so we don’t have to come back and fix them in August heat.”

Funny, yes. But also unsettling. Because behind the humor was an uncomfortable truth—customers often wonder: Was that replacement truly necessary, or was it convenient for the technician?

We didn’t want to build our business on that kind of doubt. Our belief is simple: people should replace their HVAC systems only when it makes sense. Maybe the old unit finally gave out. Maybe new energy-efficient technology can cut bills in half. Maybe quieter, smarter systems make a home more livable. Those are valid reasons. But commission games? Technician fatigue? No.

And so the idea was born:

  • Give field workers AI-driven diagnostic support so they can troubleshoot faster and with more confidence.
  • Offer a second opinion instantly—not from another technician across town, but from a system that has learned from thousands of past jobs.
  • Audit our own work internally—not to play “gotcha” with our team, but to ensure our techs are making recommendations in the customer’s best interest.

We’ve been running this process quietly inside our company for a while now. The results surprised even us: faster diagnoses, fewer unnecessary replacements, and, maybe most importantly, a growing trust between customers and our crew.

Recently, the founding story of ServiceTitan lit another spark. If they could transform contractor software from a family garage, why couldn’t we take our scrappy, heat-forged solution and see if it could help others?

Of course, building an app for external users comes with a new layer of risk—data security, compliance, liability, all those things that don’t matter much when you’re just solving problems internally. So we’re moving carefully. Very carefully. Starting with a tiny, tightly defined scope. Testing the waters, one feature at a time.

Because in the end, this isn’t about chasing commissions, or growth at all costs. It’s about trust. About standing in a sweltering Texas attic in July, knowing the customer downstairs can rely on what you say, and why you say it.

And maybe, just maybe, about making sure fewer people quit this trade—not because of the heat, but because they finally have the right tools in their hands.
