HVAC vs plumber vs electrician: comparing the three building trades

The fastest way to compare three trades is the same table.

Every pay and outlook figure below comes from the BLS's May 2025 Occupational Employment and Wage Statistics (released May 15, 2026) and the 2025–35 Employment Projections (released August 27, 2026):

Read the pay rows together: at the median the three trades sit within $2,790 of one another — $63,800 for the plumbing category, $63,190 for electricians, $61,010 for HVACR mechanics and installers.

At the 90th percentile the plumbing and electrical figures are nearly identical ($108,420 and $108,510), and the HVACR figure trails at $95,210 — the only one of the three below six figures.

Size is where the trades really differ: electrical is the largest occupation of the three by a wide margin, with 757,220 wage-and-salary jobs against 465,840 for the plumbing category and 409,670 for HVACR.

Three caveats before you take any cell at face value.

The plumbing category bundles plumbers with pipefitters, steamfitters and sprinkler fitters — O*NET merged the old codes into one — so no federal figure isolates plumbers alone.

The HVACR figure likewise counts refrigeration technicians inside it; there is no separate code.

And these job counts are wage-and-salary only: BLS excludes the self-employed from OEWS, while the projections include them.

The electrical column carries a caveat of its own: the BLS and O*NET detail in our vault runs deep for HVAC and plumbing work and thin for the electrical trade, so that column is described by its statistics rather than its day-to-day.

Our HVAC technician guide and plumber guide each cover a trade in depth.

Honestly: no federal answer exists, and a page that crowns one trade is guessing.

No licence for any of the three trades is federal — the licence ladders, their hour totals, exams and tiers are set state by state, and often city by city.

The fastest trade to enter is therefore the one whose ladder in your state has the shortest run to the work you want, on the route you choose: helper work, trade school or a registered apprenticeship.

A registered-apprenticeship completion certificate is nationally recognised.

It is a credential, not a licence — the licences themselves are issued by states and cities — and our research did not confirm how a certificate carries across state lines, so treat portability as a question for your state board rather than a given.

What the federal data can measure is how many doors open.

Electricians absorbed the most hiring churn in the projections — about 72,700 openings a year against about 42,000 for the plumbing category and about 40,600 for HVACR — though that is mostly the arithmetic of a larger occupation turning over more jobs, not a sign that any one trade is easier to break into.

The one genuinely federal layer belongs to HVAC: under 40 CFR 82.161, anyone who could reasonably open the refrigerant circuit while maintaining, servicing, repairing or disposing of appliances containing regulated refrigerants must pass an exam from an EPA-approved technician certification program — the EPA 608 certification.

It is an exam-based certification rather than an experience ladder, and it sits alongside whatever licence your state requires, not instead of it.

What each trade's ladder looks like where you live is a state-board question: our HVAC licence guide and plumbing licence guide walk the rungs, and your state electrical board owns the electrical one.

The salary question has a catch: BLS publishes no apprentice, journeyman or master wage table for any of the three trades, so no one can quote you a federal figure "per stage".

What it does publish is each occupation's full wage distribution — the honest stand-in.

Here is the national picture, wage-and-salary workers, May 2025:

The entry end of the distribution is close — the 25th-percentile figures run from $48,360 for HVACR to $50,190 for the plumbing category, with electricians at $49,430 between — and the plumbing category edges the other two at every published point except the last: at the 90th percentile, electricians nose ahead $108,510 to $108,420.

The HVACR 90th percentile, $95,210, is the only one of the three below six figures.

Even the entry-stage helper numbers, where BLS publishes them, cluster: plumbing helpers have a trade-specific federal category (SOC 47-3015) with a median of $20.36 an hour or $42,360 a year, while the broader all-trades helper category BLS uses behind the HVAC side shows $19.05 an hour or $39,630 a year; no separate helper or apprentice figure exists for electricians at all.

Where you live moves the number more than which trade you pick.

State medians ran to $101,020 in DC and $99,950 in Illinois for the plumbing category, $101,310 in Oregon for electricians, and $84,390 in DC and $77,430 in Alaska for HVACR; by metro, the leaders were San Jose-Sunnyvale-Santa Clara, California ($107,560) for the plumbing category, Kankakee, Illinois ($105,500) for electricians, and Fairbanks-College, Alaska ($93,820) for HVACR.

Each trade's highest-paying industries in the federal data, meanwhile, are small niches rather than typical jobs: computer systems design ($115,910) for HVACR, electric power generation ($115,310) for the plumbing category, and natural gas distribution ($131,780) for electricians.

Scope note first: BLS's projections model a decade of trend, not a recession, so no table can tell you which trade survives a downturn best.

What the 2025–35 projections do show is that none of the three is projected to shrink — HVACR leads on growth at 10.9%, electricians follow at 9.2%, and the plumbing category projects 6.8% — all against a 3.5% average across all occupations.

On raw opportunity, electricians combine the largest workforce (757,220 wage-and-salary jobs) with the most openings a year (about 72,700), against about 42,000 for the plumbing category and about 40,600 for HVACR.

The structural fact worth weighing: all three trades anchor to the same employer industry.

Building equipment contractors employed 305,330 HVACR mechanics and installers, 340,140 plumbers, pipefitters, and steamfitters, and 560,290 electricians in May 2025 — the single largest employer group for each occupation.

The three trades lean on the same industry for the biggest share of their jobs, which means their fortunes move together more than any ranking suggests.

The federal data cannot settle how each trade weathers a specific recession; what it supports is that all three enter one with growth projected above the all-occupation average behind them.

The numbers above are close enough that the work should make the decision.

A $2,790 median spread is noise next to what your market, your employer's pay plan and your skill level will decide over a career.

Choose by which trade's ordinary Tuesday you can live with:

• HVAC suits the machine-diagnosis mind. BLS lists the trade's duties as installing, maintaining and repairing HVACR systems, installing electrical components, inspecting and testing systems, and discussing malfunctions with customers — a troubleshooting trade as much as an installation one. O*NET's survey describes the conditions: 58% of HVACR mechanics report working outdoors in all weather every day, 34% report very hot (above 90°F) or very cold (below 32°F) temperatures every day, and 31% report daily exposure to high places. Attics, rooftops and mechanical rooms come with the trade — and so does the highest days-away injury rate of the three (214.5 per 10,000 full-time workers in 2023–24, about 2.5 times the all-occupation rate of 86.6).
• Plumbing suits the system-builder. BLS describes plumbers as installing and repairing water, gas and other piping systems, plus the fixtures and appliances attached to them — measuring, cutting, joining and routing the lines themselves. The trade's signature discomforts are the spaces the pipe runs through: 21% of O*NET respondents report working in cramped spaces or awkward positions every day (43% at least weekly), and OSHA says trench collapses pose the greatest risk to workers' lives in trenching and excavation, which is why the agency prescribes sloping, benching, shoring or shielding. The plumbing days-away rate sits between the other two trades at 144.5.
• Electrical suits the reader who wants the largest market and the lowest measured injury rate of the three (96.6 days-away cases per 10,000) — and who will check their own state's ladder. Fair scope note: this site's research covers HVAC and plumbing licensing in depth, not electrical, so we link the two deep dives below rather than mapping the electrical trade here.

Caught between two of the three?

The deep dives go further than this summary can: HVAC vs electrician weighs the refrigerant trade against the electrical one, HVAC vs plumbing does the same for the pipe trades, and if the call comes down to the pipe trades against the electrical one, the plumbing cluster owns that head-to-head at plumber vs electrician.
