Electricians, plumbers and HVAC technicians are often grouped together as the “big three” construction trades. All three pay above the national median, all three are growing faster than average, and none requires a college degree. So how do you choose? This comparison of electrician vs. HVAC vs. plumber looks at pay, job growth, training time, licensing and the day-to-day reality of each trade, using official data from the U.S. Bureau of Labor Statistics (BLS).
The three trades side by side
| Electrician | Plumber | HVAC technician | |
|---|---|---|---|
| Median pay (May 2025) | $63,190 | $63,800 | $61,010 |
| Lowest-paid 10% earned under | $42,640 | $44,150 | $40,050 |
| Highest-paid 10% earned over | $108,510 | $108,420 | $95,210 |
| Jobs (2025) | 821,000 | 510,600 | 440,900 |
| Growth, 2025–35 | 9% | 7% | 11% |
| Openings per year | About 72,700 | About 42,000 | About 40,600 |
| Typical training | 4–5 year apprenticeship | 4–5 year apprenticeship | 6-month to 2-year program, or apprenticeship |
| Self-employed | 7% | 8% | 6% |
Which trade pays the most?
Verdict: plumbing and electrical work are essentially tied; HVAC trails slightly.
Plumbers edge out electricians at the median ($63,800 vs. $63,190), but the $610 difference is too small to base a decision on. The bigger gap is at the top: the highest-paid 10% of electricians and plumbers earned more than $108,000, while the top 10% of HVAC technicians earned more than $95,210. In other words, all three trades pay well, but electrical and plumbing work have a higher ceiling.
In all three trades, who you work for matters as much as which trade you pick. Government jobs paid the highest median among the main employers of electricians ($79,820) and plumbers ($71,660). For HVAC technicians, wholesale trade topped the list at $71,190. Most workers in all three trades are employed by contractors, where pay sits close to the overall median.
Which trade is growing fastest?
Verdict: HVAC grows fastest in percentage terms; electrical work adds the most jobs.
HVAC employment is projected to grow 11% from 2025 to 2035, compared with 9% for electricians and 7% for plumbers. But because the electrical trade is so much bigger, it’s expected to add the most jobs: about 75,900, versus 48,200 for HVAC and 34,500 for plumbing. The BLS points to different drivers for each trade:
- Electricians: solar and wind installations, upgrades to the power grid, and data centers and artificial intelligence pushing up electricity demand.
- HVAC technicians: commercial and residential construction (including data centers), increasingly sophisticated climate-control systems, and the need to replace or upgrade existing systems.
- Plumbers: new construction, maintenance of existing buildings, and building codes in every state that require fire sprinkler systems, which boosts demand for sprinklerfitters.
Most openings in all three trades will come from workers retiring or leaving, so demand isn’t limited to fast-growing areas. Contractors also report that all three are among the hardest positions to fill, as our look at the trades with the biggest worker shortages shows.
Which trade can you start fastest?
Verdict: HVAC.
Electricians and plumbers usually train through four- to five-year apprenticeships, with about 2,000 hours of paid on-the-job training plus technical instruction each year. HVAC is more flexible: technical school and community college programs run from six months to two years, and the required federal certification, EPA Section 608, can be earned with a single exam. Apprenticeships exist in HVAC too, and our comparison of HVAC apprenticeship vs. trade school breaks down both routes with real program data.
That doesn’t mean HVAC technicians are fully qualified in six months. Graduates still start alongside experienced technicians and build skills over years. But you can be employed and earning in the trade sooner.
How licensing compares
| Trade | What’s typically required |
|---|---|
| Electrician | Most states require a license. Exams cover the National Electrical Code and state and local codes, and continuing education is usually needed to renew. Example: Texas requires 8,000 hours of supervised training for a journeyman license. |
| Plumber | Most states require a license, typically after 2 to 5 years of experience plus an exam. Some states also license pipefitters and steamfitters or require special gas-line certification. |
| HVAC technician | EPA Section 608 certification is required by federal law for nearly all technicians who handle refrigerants. Some states and localities also require an HVAC license. |
In short, electrical and plumbing licenses are required in most states, while HVAC licensing varies more from place to place. Check your state’s rules with the CareerOneStop license finder before committing to any path.
What each job feels like day to day
Pay and growth are similar enough that the work itself is often the deciding factor.
Electricians read blueprints, run wiring, install lighting and control systems, and troubleshoot faults with testing equipment. The BLS notes that almost all electricians work full time, that overtime is common, and that common injuries include electrical shocks, falls and burns. You’ll work in cramped spaces, on ladders and, on construction or renewable energy projects, sometimes at heights or outdoors.
Plumbers install and repair water, gas and drainage systems, from toilets and water heaters to septic systems, while pipefitters and steamfitters work on industrial piping that carries chemicals, gases or high-pressure steam. The BLS says plumbers often work nights and weekends and are frequently on call for emergencies. Hazards include cuts, burns from hot pipes and soldering equipment, and falls.
HVAC technicians install, maintain and repair heating, cooling and refrigeration systems. They often work in attics, crawl spaces and on rooftops, frequently in buildings that are uncomfortably hot or cold because the system has failed. The BLS lists HVAC technicians among the occupations with the highest injury rates, and overtime spikes during peak heating and cooling seasons.
Which one fits you?
The BLS lists the qualities each trade depends on, and they point in slightly different directions:
- Choose electrical work if you like problem-solving, precise systems and technology. You’ll need good color vision to identify wires, and the trade’s links to solar power, data centers and grid upgrades give it a strong long-term outlook.
- Choose plumbing if you like physical, hands-on work and don’t mind emergencies and dirty jobs. Apprentices study math, applied physics and chemistry, and it has the highest share of self-employed workers of the three (8%) if you want to run your own business someday.
- Choose HVAC if you want to start working sooner, enjoy diagnosing mechanical and electrical problems, and like variety. You’ll use math to calculate heating and cooling loads, and you’ll deal with customers in their homes and businesses.
You’re not locked in
The three trades overlap more than people expect. HVAC work involves electrical wiring and controls, and plumbing and HVAC are often handled by the same contractors; the BLS lists “plumbing, heating and air-conditioning contractors” as the largest employer of both plumbers and HVAC technicians. The United Association union trains plumbers, pipefitters and HVACR workers within the same apprenticeship system. Many tradespeople pick up related skills over their careers, and some eventually hold more than one license.
The bottom line
There’s no wrong choice among the three: each pays well above the national median and is growing faster than average. If you want the quickest start, HVAC wins. If you want the highest ceiling and the most openings, electrical work has the edge. If you want steady repair work that every building needs and a path to running your own business, plumbing is hard to beat. Our step-by-step guide on how to become a plumber explains that path.
