The technician they send in when no one else can fix it.
Sascha Hinz Commercial HVAC/R Technician · Licensed Texas Class A A/C Contractor (any equipment, any size) · Founder & CEO, The HVAC Game.
Some jobs have already gone sideways by the time Sascha arrives — a fourth technician walking onto a site nobody else could crack. He finds the actual root cause, fixes it in sequence, and closes it for good. Fifteen years in the trade, a Class A Texas contractor license for any size of equipment, and an audience of more than 78,000 technicians who watch him work.
The story in three parts
One technician, three reputations.
The Fixer
Sent in when a job has already tanked. He inherits failed work, finds the stacked failure others missed, and closes the call for good. His role literally includes remediating call-back issues — and demand for him has spiked.
The Specialist
VRF/VRV systems, factory-certified in 2026 by Daikin and Trane / Mitsubishi Electric CITY MULTI. Trusted on critical −40°F refrigeration where there is no margin for a second mistake.
The Educator
Founder & CEO of The HVAC Game — 50M+ views and a community of technicians in their first one-to-three years, learning to troubleshoot with confidence.
“Able to diagnose and resolve complex issues efficiently.”Jonathan Todd — Lead Engineer, Interior Climate Solutions Worked alongside Sascha for three years
Field report · The Fixer
The fourth technician on a site no one could crack.
Three technicians had already been to the site. None of them closed it. Sascha was sent in fourth — and instead of chasing the same symptom, he read the whole system. What he found wasn't one fault. It was a stack of them, each one hiding the next.
He diagnosed and fixed them in sequence:
- Miswired compressor start components — the wrong fix three techs had been treating as the whole problem.
- A plugged evaporator coil starving the system of airflow.
- A failed TXV blocking refrigerant flow downstream.
Demand for that kind of diagnostic discipline has climbed sharply over the last several months. When a call has already gone sideways, his name is the one that comes up.
By the numbers · Operations
Throughput at a healthy margin — and a clearance rate that keeps customers.
He carries real throughput at a healthy margin — roughly $300,000 a year in commercial service at about a 40% gross margin, with dispatch volume more than doubling from 2024 to 2025. Because so much of his work is inherited — call-backs other technicians couldn't clear — his value isn't only volume. It's clearance: jobs that close and stay closed, which is why a dozen accounts ask for him by name.
Requested by name
More than a dozen organizations ask for Sascha by name.
Plasma centers, banks, national retail, restaurants, and churches — they don't ask for a company. They ask for him.
In the field
Rooftops, condensers, copper.

The Educator
He started with one nervous phone video. Now 78,000 technicians follow along.
The HVAC Game began with a single clip — how to wire a capacitor, about fifty views. He took a course on viral hooks, hit a 150K reel, and nearly quit four or five times over the comments. He kept going.
Today it's air conditioning education through community, collaboration, and courses. He teaches his own 5-step troubleshooting method, hosts weekly live diagnostic calls, and runs an open Q&A forum for technicians in their first one to three years — the exact audience that needs a clear head under a hot rooftop.
A repeatable diagnostic sequence taught live every week — so a first-year tech can troubleshoot with the confidence of a veteran.
Signature work · The Specialist
−40°F, a seven-day window, and a clock that was costing $50,000 a month.
Multi-stage −40°F freezers with antechamber precoolers.
A broker scoped the job at seven days. Sascha re-sequenced hundreds of checklist steps to finish inside the window, fixed a failed time clock the same day, and returned three freezers to service — ending a roughly $50,000-a-month trailer rental that had been bleeding the site.
Branch and regional managers took note. Elsewhere: a solo cooling-tower replacement, annual boiler and chiller teardowns, and a 120-ton Trane rooftop running VAV and building automation.
