The Looming Tsunami: Why HVAC is Facing a 5:2 Retirement-to-Hire Ratio?
Over the past three decades, the HVAC and building services industry has quietly slipped into a labor crisis: not for lack of work, but for lack of workers, as highlighted by labor statistics.
In the 1990s, the trades thrived on generational continuity: apprentices worked beside veterans, learning through proximity and repetition. But that apprenticeship pipeline has steadily weakened.
Trade commentary from ACHR News and workforce research indicates a 50% decrease in certified HVAC technicians over the past decade.
The average age of technicians now hovers around 55, according to the Air Conditioning Contractors of America (ACCA) Board Meeting Packet.
This aging workforce in the HVAC industry signals a looming shortage of skilled workers, making it critical to invest in certifications and training for new talent.
Some estimates show a retirement-to-replacement ratio approaching 5:2, meaning for every five technicians who retire, only two new entrants take their place.
This trend highlights the shifting demographics of employees in the sector and underscores the need for an industry focus on effective retention strategies, training, and mentorship to maintain a stable workforce and address the ongoing shortage.
The skills needed for new entrants include obtaining industry certifications, developing strong technical knowledge, and building practical abilities essential for success in the HVAC industry.
Roughly 25,000 HVAC technicians exit the workforce annually, with “far fewer” entering the trade to replace themBoard Meeting Packet.
As a result, employers are increasingly struggling to find qualified workers, facing significant hiring challenges despite the overall size of the workforce.
These are not abstract numbers: they are operational bottlenecks.
Systems are aging faster than people are being trained to maintain them. Technology is advancing faster than training programs can evolve.
And every new building electrified or automated without a capable workforce deepens the gap between infrastructure and implementation.
Broader employment trends and forecasts in the HVAC sector show that this labor crisis is part of a larger pattern affecting job growth and workforce planning across the industry, fueled by high demand.
Compared to global markets, the U.S. HVAC labor crisis presents unique workforce challenges and growth rates, with some international regions experiencing different trends in technician supply and demand.
The Juxtaposition: College Promises vs. Trade Realities
For years, young people were presented with a binary choice: college or the trades. But that dichotomy no longer reflects economic reality.
College has become a debt engine with diminishing returns, while the trades, particularly the skilled trades (especially HVAC, controls, and automation), now represent one of the most direct and debt-free paths into the clean economy.
Where a four-year degree often leads to uncertain entry-level roles, HVAC delivers tangible outcomes:
- Immediate employability
for graduates of trade programs, who quickly enter the workforce and become revenue-generating contributors, with starting salaries of $55,000–$70,000 and strong revenue potential, often with zero tuition debt. - Visible impact
improving comfort, energy efficiency, and climate performance in real buildings. - Transferable skills
across construction, facilities, and digital infrastructure.
Trade programs are cost-effective pathways to skilled careers, preparing individuals for immediate employment and long-term advancement.
The job outlook for HVAC technicians is especially strong, with growth projections and demand outpacing many other fields. In fact, HVAC jobs are growing faster than many other occupations, highlighting the increasing need for skilled technicians in this sector.
Yet the industry’s perception problem persists.
Most students (and parents) still picture the trades as wrench work, not systems work. That image is decades out of date.
The HVAC field has quietly become one of the most technology-dense sectors of the built environment, where laptops, networks, and automation dashboards are as common as screwdrivers.

The Digital Technician: Balancing Field Autonomy with Data Compliance
A defining attraction of HVAC work has always been independence, the freedom to diagnose, repair, and solve problems in the field, including work on both cooling and heating systems.
But as systems become connected and regulated, the job now carries a parallel responsibility: documentation.
Every technician today must:
- Log refrigerant movements for EPA and state compliance, ensuring proper refrigerant handling.
- Record work in each owner/operator’s digital maintenance platform CMMS.
- Record Work for invoicing in their own company accounting platform
- Verify performance through data, not just observation.
- Maintain compliance in key areas such as refrigerant handling and keep track of cylinders and inventory.
This transition (from doing to proving) marks a cultural inflection point.
The new generation of workers must balance autonomy with transparency, field judgment with digital recordkeeping.
Repairs and maintenance of heating systems are now core aspects of the technician’s job that require thorough documentation and compliance.

Our Commitment: Bridging the 4x Growth Gap Between Systems and Staff
When we began working in this industry, there were roughly 250,000 AC and far fewer active Refrigeration HVAC technicians in the United States.
Thirty years later, that number has technically grown, with the current workforce nearing 425,000 (BLS 2024), but the size of the skilled workforce has remained stagnant in impact, even as demand has exploded.
For every new technician entering the field, another is preparing to retire.
It’s not a lack of interest; it’s a systemic perception problem. Even in my own family, my kids chose different paths. Parents still see college as the “better route,” and for a long time, it was. But the world has shifted.
Today:
- Paychecks in the trades are climbing.
- Demand for skilled labor is surging.
- And the built environment is expanding faster than we can staff it.
In 1992, the U.S. had about 45 million installed HVAC systems. Today, that number exceeds 200 million, a fourfold increase. Yet the capacity of the workforce to maintain them has barely moved the needle.
That’s the imbalance we face: an industry that has scaled its equipment and developed new systems, but not its expertise.
This is why the Third Lane matters. It’s the bridge between the people we have and the systems we’ve built.
It’s the path that attracts a new kind of worker—one drawn not to wrenches and compressors, but to screens, dashboards, and diagnostics.
This lane brings new energy, new skillsets, and new perspectives into an industry that desperately needs them. It’s how we turn a static workforce into a scalable one.
And it’s why we are commercially committed to supporting the model that makes it real—the one being proven every day by Stacks+Joules.
They’re doing what many said couldn’t be done:
- Teaching automation and controls in high schools and community programs.
- Building training environments where students learn on real systems, not simulations.
- Partnering with major industry players across New York City to open career doors that never existed before.
- Graduating alumni who can now tell their own stories—of moving from classrooms to control rooms, from learning Python to programming buildings.
We’re not just cheering from the sidelines. We’re aligning our own commercial priorities with this workforce mission—investing time, data, and support to help the third lane grow.
Because without a workforce that can think in systems, we can’t meet the demand we’ve already created. The opportunity isn’t only to repair what exists; it’s to redefine who gets to participate in the future of building performance.
This is our commitment: To stand with programs that turn potential into professionals. To amplify the people who can bridge the labor gap with insight instead of overtime.
And to help ensure that, 30 years from now, we look back not on stagnation—but on the decade that finally transformed the trades.
