Electrician vs. Plumber vs. HVAC — Salary, Job Security, and Which Trade to Pick

All three trades pay well. Union electricians and plumbers sit close at the top of the skilled-trades salary bracket. HVAC technicians earn slightly less on average, but service and refrigeration specialists close that gap quickly. The short answer: the “best” trade for your wallet depends on your local market, whether you go union, and which type of work you’re actually willing to do day in and day out.

I’m an IBEW Local 134 journeyman out of Chicago, so I’ll tell you upfront: I’m biased toward electrical. I try to be honest about it below, but keep that bias in mind as you read.

Salary Comparison — BLS May 2024 Data

The Bureau of Labor Statistics releases detailed occupational wage estimates each May. Here are the most recent figures across all three trades:

Source: U.S. Bureau of Labor Statistics, Occupational Employment and Wage Statistics (OEWS), May 2024. Figures are national medians across all employer types and union statuses.

The spread between trades at the median is less than $3,400 per year — roughly $1.65/hr. That’s close enough that other factors (union status, market, specialization) will matter far more than which trade you pick.

Union vs. Non-Union Makes the Biggest Difference

The BLS figures blend union and non-union workers across all regions. That blend obscures the single biggest pay lever in the building trades: whether you join a union.

Chicago as a benchmark

• IBEW Local 134 journeyman electrician: $51.00/hr base wage + roughly $35/hr in fringes (pension, health, annuity, training fund) = approximately $86/hr total package
• UA Local 130 journeyman plumber: Comparable — journeyman scale in the high $40s to low $50s/hr base, with a similar fringe package
• SMART/UA HVAC union (sheet metal or pipefitter locals): Slightly lower in most markets but still a strong package, often $35–45/hr base

A union journeyman in any of these three trades will out-earn a non-union worker in the same trade by 40–80% when total compensation is counted. The decision to go union vs. non-union moves your pay more than the choice of trade does.

Which Trade Has the Best Job Security?

All three are recession-resilient in a structural sense: none of the work can be offshored, and none of it is meaningfully threatened by automation in the near term. Here’s where they differ:

Electricians

Broadest application of any skilled trade. Residential, commercial, industrial, data centers, electric vehicle charging infrastructure, solar installation, battery storage — electrical work touches every sector. The AI and data center build-out is driving significant new demand for both construction electricians (to build facilities) and industrial/maintenance electricians (to keep them running). The BLS projects 11% employment growth for electricians through 2033, faster than the national average.

Plumbers

Water, sewer, and gas will always need plumbers. Pipefitters and steamfitters find work in industrial plants, refineries, and power facilities. Healthcare construction (hospitals, medical centers) is a steady pipeline. The BLS projects 15% growth for plumbers and pipefitters through 2033 — the fastest of the three trades — driven partly by aging infrastructure replacement.

HVAC Technicians

Work is somewhat seasonal (heavy in spring and fall), but demand is growing. Climate change is driving cooling load increases in regions that historically didn’t need it. Data center cooling is a specialized, high-paying niche that is expanding fast. Refrigeration specialists — working on commercial refrigeration equipment — tend to earn more than residential HVAC installers and have more stable year-round work. BLS projects 9% growth through 2033.

Which Trade Is Physically Hardest?

All three will put wear on your body over a 30-year career. Here’s an honest breakdown without sugarcoating any of them:

Plumbing — hardest on joints and back

• Crawl spaces and under-slab work require tight, awkward positions for extended periods
• Cast iron pipe is heavy; older systems involve significant lifting
• Exposure to sewage, chemicals, and unpleasant working conditions is common
• Concrete cutting, jackhammering, and trenching are part of the job on many projects

Electrical — hardest on shoulders and knees

• Less heavy lifting than plumbing or HVAC, but pulling wire in attics and tight spaces is physically demanding
• Significant overhead work (drilling, running conduit) taxes shoulders over time
• Heights are a constant: ladders, scissor lifts, and aerial lifts are part of daily life on commercial jobs
• Kneeling on concrete slabs while pulling wire is rough on knees over a career

HVAC — hardest in extreme temperatures

• Rooftop unit work in summer is brutal — surfaces regularly hit 140°F+ in the sun
• Mechanical rooms are often cramped and poorly ventilated
• Refrigerant handling requires precision; chemical exposure risk exists
• Sheet metal work involves sharp edges and repetitive motion injuries

Nobody in any of these trades makes it to 65 without some wear. The question is which kind of wear you’d rather deal with. If heights bother you, electrical may not be right. If tight spaces and smells are a dealbreaker, plumbing may not fit. If you hate summer outdoor work, HVAC installs will be rough.

Which Trade Is Easiest to Get Into?

The paths vary significantly depending on whether you go union or non-union:

HVAC — fastest path to working

1. 6–12 month trade school or community college program
2. Pass EPA 608 certification (required to handle refrigerants)
3. Start working — typically as a helper or entry-level tech
4. Total time to employed: 6–18 months

Non-union electrical or plumbing — similar to HVAC

1. Trade school or vocational program: 1–2 years
2. Work as a helper/apprentice under a licensed contractor
3. Sit for state journeyman exam after meeting hour requirements (varies by state)
4. Total time to journeyman: 2–4 years depending on state

Union apprenticeship (IBEW or UA) — slower start, better finish

1. Pass the aptitude test and interview to get on the eligibility list
2. Get called from the list (waiting period varies by local — weeks to 1–2 years)
3. 5-year apprenticeship: paid from day one, stepping up every 6 months
4. Journeyman card at the end with full benefits throughout training
5. Total time to journeyman: 5–6 years from start

The union path takes longer but pays more during training than most people expect, and the journeyman card at the end is worth significantly more than a non-union license in most markets.

Market-Specific Differences

National medians are a rough guide. Your local market matters more than any national average when making this decision.

• Sun Belt (Texas, Arizona, Florida, Southeast): HVAC demand is highest here due to climate. Non-union electrical and plumbing also pay reasonably well, but union presence is weaker than in the Midwest or Northeast.
• Northeast and Midwest: Strong union presence for both IBEW and UA. Union scale wages are highest here. Chicago, New York, Boston, and Philadelphia all have premium union rates.
• West Coast: Strong union electrical (IBEW) and plumbing (UA). High cost-of-living markets with correspondingly high scale wages — but housing costs absorb much of the premium.
• Rural markets: All three trades typically pay less in rural areas. Electricians may have an advantage in rural markets due to broader application (residential service, ag facilities, light commercial).

Before committing to a trade, look up your local IBEW or UA local’s published wage rates, and compare to what non-union shops in your area actually advertise. A 5-minute Google search on your local union’s website will give you more useful data than any national average.

Bottom Line Recommendation

If you want the highest pay ceiling and best benefits package

Union electrical (IBEW) or union plumbing (UA) — they’re comparable. In major metro markets, both can put a journeyman at $85–100+/hr total compensation within 5 years. The difference will come down to which local you can get into and which work environment you prefer.

If you want the fastest path to earning a living wage

HVAC. Six to twelve months of trade school plus an EPA 608 cert and you can be employed. Pay ceiling is lower than union electrical or plumbing, but you’re earning sooner.

If you want the best blend of demand, pay, and long-term growth

Electrical — specifically union electrical in a market with strong IBEW presence. The convergence of data center construction, EV charging infrastructure, grid modernization, and solar/storage installation is creating structural long-term demand that is broader than any single sector. Electricians who can work across commercial, industrial, and renewable energy settings will have the most options.

But plumbing is right behind it, and if you have access to a strong UA local, the career math is very similar. HVAC is a legitimate trade with real money in the right specialties. None of these are bad choices. The wrong choice is picking one based purely on a national salary chart instead of your local market and what you actually want to do every day.
