Registered apprenticeships: the cheapest way to grow your own technicians, with the math

A registered apprenticeship is the cheapest way to grow your own technicians, but not in year one. In year one an apprentice costs more per productive hour than an experienced tech. By year three, on a real state-registered HVAC wage schedule and reasonable assumptions about output, they cost about the same. After that you have a journey-level tech you trained your way, at a time when BLS projects about 40,600 HVAC openings a year through 2035¹. The registration part adds structure, a wage ladder the apprentice can see, and access to tax credits and training money that informal "helper" programs don't get.

This post covers what registration actually requires, what the national numbers show (HVAC uses apprenticeship far less than electrical does), a year-by-year cost model, the incentives worth checking in your state, and how to start.

What a registered apprenticeship actually requires

"Apprentice" gets used loosely. A helper who rides along and gets a raise when the owner remembers is not in a registered apprenticeship. A registered program is one whose standards are approved by the U.S. Department of Labor's Office of Apprenticeship or a state apprenticeship agency, under 29 CFR Part 29. The federal standard lists what a program has to include²:

Two things to notice. First, the federal rule sets no fixed ratio; each program's standards set one, and state licensing law may override it. Second, the rule has been stable. The Department of Labor proposed a major rewrite in January 2024 and withdrew it in December 2024³, so the 2008 standard, as amended in 2016, still applies.

For licensed trades, apprenticeship isn't optional in practice. BLS says most electricians and most plumbers learn the trade through a four- or five-year apprenticeship, and that plumbing apprentices typically get about 2,000 hours of paid on-the-job training a year⁴. For HVAC, BLS says only that some techs train through an apprenticeship, which usually lasts several years¹.

What the national numbers show

The Department of Labor reported these figures for the fiscal year ended September 30, 2025, combining federal and state registration agencies⁵:

DOL also says 93% of apprentices keep their employment after completing, and puts the average starting salary at $86,000⁶. Both are DOL's own headline figures, based on its program data, and they describe employment in general, not staying with the employer who trained them.

The more useful number for a service contractor is the split by occupation. In January 2026 estimates, DOL counted about 132,022 active apprentices in electrician programs, 64,142 in plumber and pipefitter programs, and just 15,163 in HVAC and refrigeration⁵.

Put those against employment and the gap is stark. BLS counted about 409,670 HVAC mechanics and installers, 465,840 plumbers, pipefitters and steamfitters, and 757,220 electricians in wage and salary jobs in May 2025⁷. As a rough ratio, there's about one registered apprentice for every 6 electricians and every 7 plumbers, but only one for every 27 HVAC techs. The licensing rules in electrical and plumbing push shops into apprenticeship. HVAC, mostly unlicensed below the contractor level, relies on informal helper training. That's a gap an HVAC shop can use: fewer competitors for the same apprentices, the same incentives, and a recruiting pitch ("a registered program with a written wage ladder") most of the shops around you can't make.

The wage schedule: a real example

Apprentice pay is set as a percentage of the journey-level rate and rises on a schedule. Here's the schedule from a state-registered HVAC/R technician program in Oregon, revised January 2026⁸. The program runs 8,000 hours of on-the-job learning, requires at least 144 hours of related instruction a year, and uses a journey average wage of $39.69 an hour.

The same program uses a ratio of one apprentice to the first journey-level worker on the job site and a probation period of the first 1,600 hours or one year, whichever is shorter. Your state's programs will differ, but the shape is typical: half pay at the start, raises every six months, and a visible ladder. That visibility matters for retention; "no opportunities for advancement" is one of the top reasons people give for quitting (see why technicians quit).

What an apprentice really costs: wage per productive hour

Here's the model most owners never run. An apprentice is cheap per hour and expensive per unit of work, and the crossover is what matters.

The wages below come from the Oregon schedule above. The output shares are hypothetical: 30% of a journeyworker's production in year one, 55% in year two, 75% in year three and 90% in year four. Your numbers depend on the person and your ride-along program.

Three things this shows:

• Year one is the investment. Per productive hour, a first-year apprentice costs well over the journey rate. Add the mentor's lost time and tuition for related instruction, and year one is a cost center. That's where the incentives below matter most.
• Years three and four are roughly break-even per hour, and you also get a tech who learned your price book, your process and your customers.
• Over four years, wages total about $218,000 against about $317,500 for a journeyworker over the same 8,000 hours. The savings pay for the training, and what you're really buying is the year-five tech.

The other side of the comparison is hiring that journeyworker at all. With openings outpacing new entrants in many markets, the alternative to growing your own is often a long vacancy, not a cheaper hire.

The Commerce Department looked at employer returns in a 2016 study of 13 companies and intermediaries. Its most-cited finding, Siemens USA earning at least a 50% return on its apprenticeship program compared with hiring off the street, comes from manufacturing, not service trades, so treat it as an existence proof rather than a forecast⁹.

Money on the table: incentives worth checking

Incentives change often, and lists online go stale. Verify each one with the agency before counting on it. Here's what we confirmed on official sites as of summer 2026:

Apprenticeship.gov keeps a broader state list of tax credits and tuition support, about two dozen states, but some entries lag behind changes, so treat it as a starting point¹⁷.

Ratios and supervision

How many apprentices a journeyworker can supervise is set by your program standards and, in licensed trades, by state law. Two examples from state statute:

• Washington: for most electrical work, no more than one noncertified person per certified journey-level or master electrician, who must be on the same job site for at least 75% of each working day¹⁸.
• Michigan: one journeyman or master electrician to no more than three registered apprentice electricians, enforced job site by job site¹⁹.

Ratios change your growth math. At 1:1, every apprentice needs a journeyworker on the same job, so your apprentice count can't outrun your experienced crew. Plan the program around how many journeyworkers will actually mentor, not how many you employ.

How to start a program

1. 1

   Decide: sponsor or join

   You can register your own program, or join a group program run by a trade association, community college or joint apprenticeship committee that handles the paperwork and instruction. For a shop with one to three apprentices, joining is usually easier.

2. 2

   Call your state apprenticeship agency

   Some states register programs themselves; others use DOL's Office of Apprenticeship. Apprenticeship.gov lists the contact for each state. Ask about existing standards for your occupation that you can adopt.

3. 3

   Write or adopt the standards

   Term, work processes (what the apprentice will learn on the job), related instruction, wage schedule, ratio, probation and selection procedures. Start from an approved standard for your occupation rather than a blank page.

4. 4

   Line up related instruction

   A community college, trade school or association course. Ask about tuition support; some states and WIOA funds pay for it.

5. 5

   Register apprentices and track hours

   Each apprentice is registered individually. Keep on-the-job and classroom hours by work process; you'll need them for wage steps and completion.

6. 6

   Claim the incentives

   Talk to your local workforce board about WIOA on-the-job training before you hire, and to your tax preparer about state credits.

Track the hours carefully. Wage increases, completion and some tax credits depend on them, and a program that can't show its hours has a problem at the next review. In TradesWork, timesheets include a built-in Training time code alongside drive and on-job time, which gives you a clean record of classroom and training hours, and techs can carry certifications with expiry dates so dispatch knows who's cleared for what. A full apprenticeship record by work process still lives with your program sponsor.

Federal policy right now

Apprenticeship has broad political support. Executive Order 14278, signed in April 2025, directed the Secretaries of Labor, Commerce and Education to deliver a plan to reach and surpass 1 million new active apprentices²⁰. In practice, the funding most useful to a small contractor is still the long-standing kind: WIOA training funds through local workforce boards and state tax credits. New federal grant programs announced since 2025 have mostly targeted manufacturing occupations, so check eligibility before planning around one.

Where a registered program doesn't fit

If you have no journeyworker who wants to teach, fix that first. An apprentice without a mentor is just a cheap helper with a schedule of raises.

For the day-to-day teaching, the ride-along ladder fits inside a registered program's on-the-job hours.
