TL;DR:
- 200,000+ skilled trade positions go unfilled annually across HVAC, plumbing, and electrical (NECA, PHCC, ACCA estimates, 2025)
- Electricians are the most constrained: 11% projected growth, but trade school enrollment covers only 55-60% of projected openings
- 25% of HVAC technicians are over 55 years old — retirement attrition will accelerate through the decade
- The hardest metros to hire: Phoenix, Dallas, Houston, Atlanta, Denver, Charlotte, Nashville, Orlando, Las Vegas, and Columbus
- Technology leverage (AI scheduling, optimized dispatch) can extend each technician's daily capacity by 1-2 jobs — the only near-term solution available at scale
The Structural Nature of the Problem
The technician shortage in field service is not a cyclical problem. It is structural, and it has been building for 15 years.
The causes are well-documented: a generation of high school counselors steered students toward four-year degrees, trade school enrollment declined relative to population growth, and the skilled workers who entered the trades in the 1990s are now approaching retirement. The pipeline that produces journeymen takes 4-5 years from apprenticeship entry to independent licensing — there is no short-term fix.
Understanding where shortages are worst — by geography, by trade, and by career stage — helps contractors make better hiring and technology decisions.
National Overview: The Numbers
National Unfilled Trade Positions (2025 Estimates)
| Trade | Estimated Open Positions | Annual BLS Projected Openings | Pipeline Coverage |
|---|---|---|---|
| HVAC Technicians | 55,000-75,000 | 79,900 | ~65% |
| Plumbers / Pipefitters | 40,000-55,000 | 48,600 | ~70% |
| Electricians | 75,000-95,000 | 73,500 | ~55-60% |
| Total (3 trades) | 170,000-225,000 | 202,000 | — |

The electrician shortage stands out. Despite having the highest projected growth rate of the three trades (11%), electrical has the lowest pipeline coverage ratio — meaning trade school graduation rates cover a smaller share of projected annual openings than HVAC or plumbing. This reflects both demand-side surge (data centers, EV charging, electrification) and a supply-side lag from years of declining vocational enrollment.
For contractors, this translates directly into hiring timelines. In 2019, the average time to fill a journeyman electrician position was 6-8 weeks. By 2025, that figure had extended to 10-16 weeks in competitive metro markets.
BLS Growth Projections by Trade (2024-2034)
10-Year Employment Projections
| Occupation | 2023 Employment | 2033 Projected | Net New Jobs | % Growth | Annual Openings |
|---|---|---|---|---|---|
| HVAC Mechanics/Installers | 399,600 | 424,500 | 24,900 | 6% | 79,900 |
| Plumbers, Pipefitters, Steamfitters | 473,900 | 485,100 | 11,200 | 2% | 48,600 |
| Electricians | 762,600 | 849,800 | 87,200 | 11% | 73,500 |
Source: BLS Occupational Outlook Handbook, 2024-2034 edition
A note on interpreting these figures: the "Annual Openings" number is larger than the net new job growth because it includes replacement openings — positions vacated by workers who retire, change occupations, or leave the labor force. For trades with aging workforces, replacement openings often dominate the total.
Plumbing's 2% growth projection does not mean plumbing is a low-demand trade. It means employment growth is constrained by supply, not by demand. PHCC surveys consistently show 60-65% of member contractors turned down work in 2024 because they lacked staffing.
Aging Workforce: The Retirement Wave
The single most pressing near-term driver of the shortage is retirement attrition.
Age Distribution of Skilled Trade Workers (2024)
| Age Group | HVAC | Plumbing | Electrical |
|---|---|---|---|
| Under 25 | 8% | 7% | 9% |
| 25-34 | 22% | 21% | 23% |
| 35-44 | 24% | 25% | 25% |
| 45-54 | 22% | 23% | 22% |
| 55-64 | 17% | 17% | 15% |
| 65+ | 7% | 7% | 6% |
| Over 55 total | 24% | 24% | 21% |
Source: BLS Current Population Survey, 2024; ACCA Workforce Report, 2024
Roughly one in four HVAC and plumbing technicians is within 10 years of typical retirement age. As this cohort exits the workforce over the next decade, annual replacement demand will increase beyond current BLS projections.
The generational pipeline math is unfavorable. Workers aged 25-34 represent 22% of the HVAC workforce. For this cohort to replace the over-55 cohort (24%) as they retire, the industry needs near-perfect retention of younger workers — which has historically not happened. Career changers in their 30s and 40s often leave trades for management roles, sales, or business ownership after gaining experience.
Trade School Enrollment: The Pipeline Constraint
The most direct measure of future supply is trade school and apprenticeship program enrollment.
Apprenticeship and Trade School Enrollment Trends
| Year | HVAC Apprentice Enrollments | Plumbing Apprentice Enrollments | Electrical Apprentice Enrollments |
|---|---|---|---|
| 2018 | 22,400 | 31,200 | 45,800 |
| 2020 | 19,800 | 28,600 | 41,200 |
| 2022 | 23,100 | 32,400 | 47,600 |
| 2024 | 26,500 | 35,800 | 54,200 |
Source: ACCA HVAC Workforce Report 2024; PHCC Foundation Workforce Study 2024; NECA Workforce Survey 2025
Enrollment is growing. The 2024 figures represent meaningful increases from the 2020 pandemic trough, and the absolute numbers are at multi-year highs. This is positive.
However, enrollment growth still lags the combination of demand growth and retirement attrition. A plumbing apprentice who enrolled in 2024 will complete their apprenticeship and obtain journeyman status around 2028. The near-term shortage (2024-2028) is essentially locked in — there is no enrollment decision made today that changes conditions in the next three years.
Geographic Shortage Index: Where Hiring Is Hardest
Not all markets are equally constrained. The shortage concentrates in high-growth Sun Belt metros where population growth creates service demand faster than the local trade workforce expands.
State-Level Technician Availability Index (Lower = Harder to Hire)
| State | HVAC Index | Plumbing Index | Electrical Index | Overall |
|---|---|---|---|---|
| Illinois | 1.12 | 1.18 | 0.98 | Hard (union-constrained) |
| New York | 0.98 | 1.05 | 0.89 | Very Hard |
| Texas | 0.72 | 0.78 | 0.68 | Extremely Hard |
| Florida | 0.69 | 0.74 | 0.65 | Extremely Hard |
| Arizona | 0.65 | 0.71 | 0.61 | Extremely Hard |
| Georgia | 0.71 | 0.76 | 0.68 | Extremely Hard |
| Colorado | 0.73 | 0.79 | 0.70 | Extremely Hard |
| North Carolina | 0.74 | 0.80 | 0.72 | Extremely Hard |
| Tennessee | 0.76 | 0.82 | 0.73 | Very Hard |
| Nevada | 0.68 | 0.75 | 0.64 | Extremely Hard |
| Ohio | 0.89 | 0.95 | 0.84 | Hard |
| Pennsylvania | 0.94 | 1.00 | 0.88 | Moderate-Hard |
| Michigan | 0.93 | 0.98 | 0.87 | Moderate-Hard |
| Massachusetts | 1.08 | 1.14 | 0.96 | Hard (union-constrained) |

The Sun Belt pattern is clear. Texas, Florida, Arizona, Georgia, Colorado, and Nevada — all high-growth states with significant new construction and HVAC demand — are the hardest markets to hire in. Illinois and Massachusetts run hard for different reasons: strong union halls control supply, and non-union contractors compete for a smaller pool of available workers.
Top 10 Hardest Metro Areas to Fill Trade Positions
Hardest Hiring Markets by Metro Area (2025)
| Rank | Metro Area | Primary Trade Shortage | Contributing Factors |
|---|---|---|---|
| 1 | Phoenix-Mesa-Scottsdale, AZ | HVAC, Electrical | Population growth 3.2%/yr; construction boom |
| 2 | Dallas-Fort Worth, TX | All trades | Nation's fastest-growing metro; massive construction |
| 3 | Austin-Round Rock, TX | Electrical, HVAC | Tech sector growth; data center buildout |
| 4 | Nashville-Davidson, TN | Electrical, Plumbing | Rapid population growth; low historical trade base |
| 5 | Charlotte, NC | Electrical, HVAC | Financial sector growth; suburban expansion |
| 6 | Denver-Aurora, CO | All trades | Mountain West hub; sustained growth pressure |
| 7 | Orlando-Kissimmee, FL | HVAC, Plumbing | Tourism + residential; high turnover in service roles |
| 8 | Las Vegas-Henderson, NV | HVAC, Electrical | Hospitality demand + residential growth |
| 9 | Atlanta-Sandy Springs, GA | All trades | Southeast hub; data center and industrial growth |
| 10 | Columbus, OH | Electrical, HVAC | Intel fab investment creating massive electrical demand |
Source: NECA Regional Workforce Data, 2025; PHCC State of the Industry, 2025; ACCA Regional Reports, 2025
Columbus, Ohio deserves special attention. Intel's $20B semiconductor fabrication investment in the Columbus metro has created an extraordinary demand spike for industrial electricians and HVAC technicians. The local trade workforce was not sized for this level of industrial construction, and contractors across residential and commercial service are competing with industrial projects offering substantial wage premiums.
Wage Pressure From the Shortage
Labor scarcity translates directly into wage inflation. Contractors in shortage markets are not competing only with other service contractors — they are competing with commercial and industrial projects that can offer higher wages for the same certifications.
Wage Premium in High-Shortage Markets vs. National Median (2024)
| Metro | HVAC Premium | Electrical Premium | Plumbing Premium |
|---|---|---|---|
| Phoenix | +12% | +18% | +14% |
| Dallas-Fort Worth | +9% | +16% | +11% |
| Denver | +11% | +19% | +13% |
| Charlotte | +8% | +15% | +9% |
| Nashville | +7% | +13% | +8% |
| Las Vegas | +13% | +20% | +15% |
Source: BLS OEWS Metropolitan Area Data, May 2024; regional NECA and PHCC chapter surveys, 2025
These premiums compound hiring difficulty. A Phoenix HVAC contractor who needs to pay $65,000+ to hire a journeyman (vs. $57,300 national median) is facing both a smaller pool of available workers and a higher per-hire cost.
Impact on Contractors: The Operating Reality
The shortage affects contractors in four measurable ways:
1. Longer hiring cycles. Average time-to-fill for a journeyman in a shortage market has extended from 6-8 weeks (2019) to 10-18 weeks (2025). Jobs that go unfilled for 12+ weeks are revenue opportunities that do not materialize.
2. Wage pressure above budget. Contractors who budgeted compensation at national median rates are routinely being outbid in shortage markets. Signing bonuses of $2,000-5,000 have become common for experienced journeymen in the top-10 shortage metros.
3. Overtime cost. When you cannot hire, existing technicians work longer hours. ACCA survey data shows that 58% of HVAC contractors in shortage markets ran overtime exceeding 15% of total labor hours in 2024. Overtime premium (1.5x for hours over 40/week) adds directly to cost without adding capacity proportionally.
4. Turned-down work. The most direct revenue impact. PHCC estimates that 62% of plumbing contractors in shortage markets declined at least $50,000 in revenue in 2024 due to staffing constraints. The ACCA equivalent figure for HVAC is 58%.
Strategies for Shortage Markets
Contractors who successfully navigate shortage markets employ overlapping strategies rather than relying on any single approach.
Build your own pipeline. Companies running their own apprenticeship programs are less dependent on the open market for journeymen. The 4-5 year investment timeline is real, but contractors who started programs in 2020-2022 are now benefiting. PHCC and ACCA both offer apprenticeship frameworks that non-union contractors can adopt.
Increase retention aggressively. In shortage markets, keeping the technician you have is more cost-effective than hiring a replacement. The fully loaded cost of technician turnover (recruiting, onboarding, productivity ramp) ranges from $15,000-35,000 per departure. Structured pay scales, clear advancement criteria, and quality equipment reduce turnover meaningfully.
Recruit from adjacent markets. The salary gap between Arkansas ($47,000 median electrical) and Texas ($75,000+ in shortage markets) creates relocation economics. Contractors in high-shortage metros are offering relocation packages of $3,000-8,000 to attract candidates from lower-cost regions.
Use technology as a workforce multiplier. This is the only strategy that improves capacity without requiring additional headcount. AI-powered scheduling optimizes each technician's day, reducing drive time and idle time while increasing jobs completed per day.
Quantifying the technology multiplier:
| Baseline (Manual Scheduling) | With AI Scheduling |
|---|---|
| 4.2 jobs/tech/day | 5.1-5.4 jobs/tech/day |
| 28% of work time in transit | 18-22% in transit |
| 18% no-show/cancellation rate | 10-12% no-show rate (with reminders) |
| After-hours calls → voicemail | After-hours calls → booked (AI voice) |
Source: Exoserva platform data; ServiceTitan 2025 Industry Benchmark Report
Moving from 4.2 to 5.1 jobs per tech per day on a 5-technician team is the operational equivalent of adding 1 full-time technician — without hiring, training, or paying benefits. In a market where a qualified journeyman is unavailable at any price, this is not a minor optimization. It is the primary growth lever available.
The 2026-2030 Outlook
The shortage will not resolve quickly. The enrollment growth visible in 2022-2024 apprenticeship data will begin producing journeymen around 2027-2029. In the interim, contractors should plan for continued constraints.
The markets that will experience the most pressure through 2030: Sun Belt metros with continued population growth (Phoenix, Dallas, Austin, Nashville, Charlotte), and industrial-adjacent markets experiencing construction demand surges (Columbus, Houston, Midlands SC for BMW/Rivian).
The most resilient contractors in shortage markets will be those who have built both pipelines — their own apprenticeship programs for the long run, and technology leverage for the near term.
