Contractors teaching contractors. That's the idea this school was built on in 1994, when a Las Vegas contractor and a high school teacher opened its doors — and it's never changed hands to anyone who didn't live it. Thirty-two years later, this Las Vegas trade school is owned by two licensed contractors, and every instructor on the floor came off a job site before they ever stood in front of a class. Nobody here teaches from a textbook they haven't lived. The labs at 3139 Westwood Dr — 16,000+ square feet of them — run on real, working equipment because that's how the trade is actually learned: tools in hand, an experienced tech at your shoulder, 20 students to a class, job-ready in 12 weeks. Three decades of Las Vegas technicians started exactly this way. The legacy continues.
Quality Training Centers is founded by Leroy Brown, a Las Vegas high school teacher, and Jeff Stewart, owner of Quality Air Conditioning. A teacher who knew how people learn, and a contractor who knew what the field demands — that combination is still the DNA of the school: real education, built for real job sites. The first classroom? A much smaller space at 3139 Westwood Dr — the same address the school calls home today.

From its earliest years the school is licensed by Nevada's Commission on Post-Secondary Education, approved for the training of veterans, and approved by the U.S. EPA as a technician certification organization under Section 608 of the Clean Air Act — the same approvals we hold today.
Growing enrollment pushes the school out of its original Westwood space and into a larger campus on S. Valley View Blvd — the first sign that Las Vegas wanted more of what QTC was teaching.
The Valley View campus
Twenty-two years ago our website made the same commitments it makes now: state-licensed, VA-approved, EPA 608 certification on campus, and hands-on labs with real equipment. The look has changed. The standards haven't.

Class after class, QTC graduates go to work for HVAC and electrical contractors across the valley — and for the properties that define Las Vegas: the Bellagio, Mandalay Bay, Caesars Palace, and the Wynn. Some go further and start companies of their own.

After outgrowing Valley View too, the school comes full circle — back to 3139 Westwood Dr, this time with 16,000+ square feet for the labs that hands-on training demands. Same address where it all started in 1994.
Lonny had worked for Jeff Stewart's Quality Air Conditioning since April Fool's Day, 1987 — nearly three decades on the contracting side, and no joke — before crossing over to teach at the school Jeff co-founded. A contractor becoming an instructor isn't a career change here; it's the house philosophy in action.
Thirty-one years after he started with Jeff's company, Lonny becomes an owner of the school alongside him. From the field, to the classroom, to the front office — the long way, which is the only way anyone gets to the front office here.
QTC adds a full electrical technician program — 12 weeks, NEC code-based, with a dedicated wiring lab — bringing the same hands-on model to the valley's other most in-demand trade.
In January 2026, Chris Roth joins Lonny Snowden as partner — two licensed contractors, both built by the Las Vegas trades, committed to continuing what Jeff and Leroy started. For Chris, it's personal: Leroy Brown, the teacher who co-founded this school in 1994, was his high school teacher. The student Leroy once taught spent the next three decades in the valley as a contractor and an educator — and then came back to the school his teacher built. Contractors teaching contractors, one generation handing the trade to the next. That's the whole point of this place.

A ribbon cutting for the newest addition to campus: the Skills Lab, a standalone hands-on training facility where students work on the real systems of a real structure. The name over the door is a statement about the whole trade — software can write emails, but it can't braze a line set or wire a panel. These are careers automation can't touch, and this building is where you learn one.

More than 10,000 graduates later, new classes still start every 6 weeks, morning, afternoon, and evening — and career services support every graduate for life.
The story isn't finished. New programs are in development, pending approval by the Nevada Commission on Postsecondary Education — and the standard won't change: real equipment, small classes, instructors who worked the trade first.
Our labs run on real, working equipment — over 80 heating, air conditioning, and refrigeration units students diagnose and repair, a motor controls wall, a dedicated wiring lab, and a framed residential build. When you tour the campus, you'll see students with tools in their hands. That's the point.

Before you ever pick up a tool, you'll talk to one of these three — about programs, schedules, financing, and whether this path fits.
The labs run every day and night of class — these two keep 16,000+ square feet of equipment ready for it.

A growing school takes more than instructors — admissions, student services, facilities, front office, all of it. If you've spent your career in the field and think you have something to teach, we want to hear from you. And if you're just great at what you do, whatever that is, we still want to hear from you.
QTC graduates work for HVAC and electrical contractors across the valley, and for the properties and companies that keep this city running:
Some graduates go on to run crews. Some become instructors. And some start companies of their own — their vans have been showing up in our alumni photos for years.
