🔧 I'm building Diagvance: AI fault detection for HVAC companies and techs.

“Know before you go”

A wrong diagnosis costs more than a part. It's a second truck roll, a free callback, and a customer who calls someone else next time.

So I'm mapping North America's furnace parts into one cross-reference database: 473,540 rows, 9,446 parts, every spec checked against the maker's own documents. Zero guessing!

I'll post daily breakdowns here: real diagnostics, cost traps, and the misdiagnoses that burn company money. Follow if you run techs or run calls. 🔧

Just for today:

Most faults never announce themselves. In one ten month study, a damper sat open with nobody in the room 8,818 times. The model flagged it. The technician still owns the call.

Homeowners drew the line.

36% say their top worry about AI in HVAC is losing human judgment. Only 11% of contractors using AI let it diagnose before a visit.

AI builds the evidence. The technician owns the call.

Quiet day at Diagvance, heads-down validating what's already in the system rather than chasing new volume.
30,562+ diagnostic fault codes and counting, building the most complete real-world HVAC diagnostic reference out there.

@NVIDIAAI It’s insane 👑🎯

[Dia @Diagvance]

Its insane, NVIDIA DGX Station models powered by the GB300 Grace Blackwell superchip typically range from $92,000 USD to $160,000+ USD (approx. $125,000 to $158,000+ CAD) depending on the OEM partner and storage or GPU configurations.

🎯Welcome to new CENTURY.

Even Microducks need a nap. 😴

[Dia @Diagvance]

@NVIDIAAI Knowledge tools, people looking for them. 🤌

🔧 The family doctor for your building.
Manufacturers see one machine. We see it all.

We're building an AI-powered diagnostic agent, backed by a deep error-code database. Here's how accurate it is so far:

@claudeai I am using three pro Claude, 18 agents work for me in this century, how lucky am i!☺️👑

[Dia @Diagvance]

🔧 LG says its new air conditioner can predict its own faults.

The MULTI V 7, unveiled at HARFKO 2026, ships with dual AI for fault prediction and diagnosis.

AI builds the evidence. The technician owns the decision.

@NVIDIAAI No way☺️

[Dia @Diagvance]

I’m standing here looking at these absolutely massive lines in Berlin for NVIDIA GTC 2026, and the energy is just electric! Thousands of us are freezing/waiting in queue, but nobody cares because Europe’s biggest AI and accelerated computing event is finally happening!

@NVIDIAAI ⁉️Wish I were there!

[Dia @Diagvance]

🔧Python + Claude with 9 agents made it possible for me to keep my project moving forward even when I’m not at home, it’s amazing!

[Dia @Diagvance]

@OpenAI I love GPT 6.0 Astra by the way😍👍

[Dia @Diagvance]

You know, people in this century stuck their neck out like entrepreneurs!

[NVIDIA @nvidia]

Entire industries will be built on open models.
Developers need the freedom to build them.

@JensenHuang on why keeping these models open and accessible matters.

[Dia @Diagvance]

@OpenAI We ll wait for it👍

[Dia @Diagvance]

🔧 Meet the future of HVAC diagnostics!

Our touchscreen prototype uses temperature changes and 5 interactive questions to predict potential HVAC system faults.

This is just the beginning of smarter HVAC troubleshooting with Diagvance.

[Dia @Diagvance]

How does it work?
