Every March or April, the air duct cleaning industry gathers for the NADCA Annual Meeting and Exposition. This year’s 37th conference took place in Colorado Springs, and the session lineup is always a useful signal of where the industry’s head is — what’s being standardized, what’s being debated, and what’s coming next for the professionals who maintain the air systems in your building.
Power Vac America has attended every year, except 2021, since 1991. Here’s what stood out from 2026.
The Standard Is the Foundation — and It’s Getting More Specific
The conference opened with full-day training courses for the Air Systems Cleaning Specialist (ASCS) and Certified Ventilation Inspector (CVI) credentials — the two core certifications that define what a qualified duct cleaning professional looks like. The ACR Standard, NADCA’s governing document for how HVAC system cleaning is performed, had its own dedicated session on the final day.
For building owners and facility managers, this matters practically. When you hire a NADCA-certified contractor, you’re hiring someone who has passed a standardized exam, commits to the ACR Standard on every job, and carries credentials that can be verified.
Power Vac America has five ASCS-certified technicians on staff, and every project has an ASCS on site. The alternative — an uncertified operator with a truck and a vacuum — has no equivalent accountability.
Inspecting Doesn’t Always Mean Cleaning
One of the featured sessions was titled Inspecting Does Not Always Lead to Cleaning — which is a more nuanced position than the industry sometimes gets credit for.
The point is that a proper HVAC system assessment should determine whether cleaning is actually warranted, not assume it is. This is how Power Vac America approaches every job. Our technicians assess the system first. If contamination is present and cleaning will improve conditions, we proceed. If a system is genuinely in good shape, we say so. That kind of honest evaluation is part of what our reviews consistently reflect — and it’s the approach the industry’s own conference is reinforcing.
Business and Safety Topics Reflect a Maturing Industry
Beyond the technical sessions, the 2026 conference included programming on business finance, carbon monoxide awareness for duct cleaners, fall protection safety, and a session specifically on making the jump from residential to commercial work. There was also a session on duct renovation — the growing area where cleaning and structural repair intersect.
This breadth reflects an industry that’s moved well past the days of low-ball door-to-door operators. The professionals at the table are running real businesses, carrying real credentials, and thinking seriously about safety, scope, and long-term client relationships.
AI Is in the Room
A product theater session from an AI company was on the schedule — something that would have been unusual even a few years ago at a trade event like this. It’s an early signal, but a real one: the technology landscape around HVAC maintenance, inspection documentation, and customer communication is shifting, and the industry is paying attention.
What This Means for Clients in the Houston Area
The professional bar for air duct cleaning continues to rise. Certification standards are more rigorous. Inspection practices are more honest. Safety and business practices are more structured. And the gap between credentialed contractors and uncredentialed ones continues to widen.
If you’re evaluating duct cleaning providers for a commercial property, an industrial facility, or a residential home, NADCA certification is one of the clearest filters available. It’s not a guarantee of everything — but it tells you someone has met a standard, and that the industry itself is invested in holding them to it.
