Most shortage stories are cyclical. A sector overhires, pay spikes, training slots fill, and four years later the gap has closed. The trades are different, and the reason is arithmetic rather than sentiment: a large share of openings come from replacing workers who retire or leave, and the pipeline takes three to five years to produce a competent journeyman. You cannot close that quickly even if everyone tries.
The Bureau of Labor Statistics projects electrician employment to grow 9 percent from 2025 to 2035, much faster than average, with about 72,700 openings a year. Demand is rising from three directions: electrification of heating and transportation, data center construction, and an aging building stock that needs servicing rather than building.
The trades where the gap is widest
General construction labor follows the housing cycle. The persistent shortages sit in the licensed and maintenance-heavy specialties, where training is long and the work cannot be deferred.
Electricians
The broadest shortage and the one most exposed to electrification: EV charging, heat pumps, battery storage, solar, and the grid work behind it. Most states require electricians to pass an exam and be licensed. Industrial and commercial electricians with controls or medium-voltage experience are scarcer still, and command a clear premium over residential work.
HVAC and refrigeration
Pulled in two directions: heat pump installation on the residential side, data center and cold chain work on the commercial side. BLS projects 11 percent growth from 2025 to 2035. EPA rules require nearly all HVAC technicians who handle refrigerants to hold Section 608 certification, and some states and localities also require HVAC technicians to be licensed.
Elevator and escalator installation and repair
A small, well-paid and quietly protected trade: BLS reports May 2025 median pay of $109,910. The equipment is safety-critical, regularly inspected and cannot be maintained remotely. Nearly all workers learn through an apprenticeship, typically four years, most states require a license, and apprenticeship slots are limited, which is why the shortage persists.
Industrial maintenance and mechatronics
Keeping automated production and warehouse equipment running. BLS projects 14 percent growth from 2025 to 2035 for its combined group of industrial machinery mechanics, machinery maintenance workers and millwrights. The role has shifted from mechanical repair toward a mix of mechanical, electrical, pneumatics, PLC and networked diagnostics. Every automation project creates maintenance demand nobody staffs for at the planning stage.
Medical equipment servicing
Biomedical equipment technicians service imaging, surgical and life-support equipment in hospitals, usually after an associate degree. The work sits under regulatory and manufacturer requirements, pays well relative to training length, and is largely recession-proof. It is also the trade most people have never heard of.
| Role | Why it pays | Time to qualify |
|---|---|---|
| Industrial / commercial electrician | Licensed work, electrification demand, controls premium | 4 to 5 years apprenticeship |
| HVAC and refrigeration technician | Certification-gated, year-round emergency calls | 6 months to 2 years of training, then field experience |
| Elevator and escalator mechanic | Safety-critical, licensed in most states, tiny talent pool | About 4 years apprenticeship |
| Industrial maintenance technician | Downtime costs are enormous; multi-skilled pool is thin | 2 to 4 years |
| Biomedical equipment technician | Regulated environment, manufacturer training required | Associate degree plus vendor training |
| Controls and PLC specialist | Bridges trade and engineering; scarce combination | 1 to 2 years on top of a trade |
The routes in
Three work, and they suit different starting points.
- Registered Apprenticeship. Programs approved by the U.S. Department of Labor or a state apprenticeship agency. You are paid from day one with scheduled raises, combine on-the-job learning with classroom instruction (federal standards recommend at least 144 hours a year), and finish with a nationally portable credential. Search openings on apprenticeship.gov. The strongest route, and competition for the better programs is real.
- Community college or trade school first. A one to two year program, then an apprenticeship or technician role. Faster to a first job in some trades, such as HVAC, but you pay rather than earn at that first stage.
- Sideways from a related trade or the military. Underused. Registered programs can grant credit for prior experience and training, so mechanical, electrical or military technical experience may let you enter partway through rather than at the start. Service members can also log apprenticeship hours while serving through the United Services Military Apprenticeship Program. Ask about credit; sponsors rarely advertise it.
Licensing is set by states and sometimes by cities or counties, and it is where plans go wrong. Electricians typically move from apprentice to journeyman to master, each tier requiring documented hours and an exam based on the National Electrical Code and state and local codes. Reciprocity between states is limited and varies by trade, so check the licensing board in the state where you plan to work before you enroll: a license that does not transfer is expensive.
The economics that make this worth a look
A licensed trade reaches full earning capacity in three to five years with little or no debt, because you are paid throughout training. Compare that with a four-year degree that starts earning at year five with a loan attached. The trades' weakness is not the money: it is that the money plateaus unless you specialize, supervise or run your own business.
What the work is actually like
Be honest about the trade-offs. The work is physical and the physicality accumulates; knees, shoulders and backs are the standard complaints of a twenty-year tradesperson. On-call rotations are common in maintenance trades, which is where a chunk of the pay comes from. Conditions are unglamorous: mechanical rooms, roofs, crawl spaces, night shifts.
Against that: the work is tangible and finishes, demand does not evaporate in a downturn the way office hiring does, and the skill cannot be offshored.
The ceiling in the trades is not the tools. It is whether you move into supervision, specialization or ownership by your mid-thirties. That is where the earnings curve splits.
Where careers go from there
The people who do best rarely stay purely hands-on. The common progressions are supervision and site management; specialization such as controls, medium voltage or a manufacturer's equipment; inspection and code enforcement, which is indoor work; training apprentices; and running a contracting business, the highest-ceiling and highest-risk route.
The specialist path is the most undervalued. Adding a scarce competence (PLC programming, refrigerant certification, a specific imaging platform) to an existing trade takes a year or less and moves you into a much smaller labor pool.
