HVAC technician and plumber are the two service trades most likely to knock on your door, and their medians are $2,790 apart — close enough that how you get paid matters more than how much. Both fix what people cannot live without; one trade’s demand is seasonal by nature, and the other’s is licensed and around the clock.
The short answer
Choose HVAC technician if you want the faster entry, you are comfortable with commission and seasonal spikes, and refrigeration or commercial work appeals as the high road. Choose plumber if you want a licensed trade with steadier year-round demand, a defined apprenticeship, and the strongest ownership path in the service trades. Both careers have a van in their future; the difference is who pays for it and when.
Pay, side by side
| HVAC technician | Plumber | |
|---|---|---|
| Median annual wage (May 2025) | $61,010 | $63,800 |
| Median hourly wage | $29.33 | $30.67 |
| Jobs, 2025 | 440,900 | 510,600 |
| Projected growth, 2025–35 | 11% | 7% |
| Average annual openings | 40,600 | 42,000 |
| Typical entry | Postsecondary certificate, long on-the-job training | High school diploma, apprenticeship |
The medians are close, but the mechanisms differ. HVAC pay swings on service versus install — service technicians earn more because diagnosis bills higher — and on commission: maintenance-plan and replacement-system spiffs can raise income substantially and create the selling pressure that is the trade’s honest ethical strain. Plumbing pay is flatter and more structural: union scale with benefits worth roughly another third, and service plumbers with commission or spiffs of their own. The ownership ceiling is stronger on the plumbing side, where a one-van operation is the classic path.
Two routes to the van
The training paths are the most decision-relevant difference:
- HVAC technician. A postsecondary certificate of roughly six to twelve months, then long on-the-job training, with a helper starting almost immediately. The federal EPA Section 608 certification is required to handle refrigerants. Speed to income is the trade’s great advantage — and the reason starting pay sits well below the median for the first two or three years.
- Plumber. A four-to-five-year registered apprenticeship with paid hours and classroom time, competitive but usually shorter queues than electrical, then journeyman licensure and an optional master or contractor ladder. Slower, but every hour is logged toward an asset.
Both trades end at a truck of your own; HVAC reaches it sooner but with thinner structural protection, plumbing reaches it later with the licence behind it.
What the day actually feels like
The HVAC day bends with the calendar. Cooling season is a blur of no-cool calls, attics at 130°F, rooftop units, and on-call refrigeration nights; a mild spring is slow and commission-based income feels it. The diagnostic skill is real — electrical troubleshooting, airflow, refrigerant charge — and the best techs are the ones who can explain a $6,000 replacement without selling.
The plumbing day splits between planned construction and emergency service. Rough-in and trim-out run on prints and inspection cycles; service work is the flooded basement and the 2 a.m. main line. The wear differs in kind: HVAC burns through heat, ladders, and attics; plumbing wears out knees and backs through kneeling, crawling, and lifting. Plumbers see more acute back and knee injuries; HVAC techs see more heat stress and ladder falls.
Job market and stability
HVAC is projected to grow 11% from 2025 to 2035, with 40,600 openings a year across 440,900 jobs — heat-pump adoption, refrigerant transitions, and a retiring workforce all push the same direction. The growth is real, but the demand curve inside the year is not: seasonality is the trade’s defining feature and commission is its shock absorber.
Plumbing grows 7%, with 42,000 openings a year across 510,600 jobs. Demand is nearly weather-proof — water does not respect the calendar — and emergency service work exists in every season. The licence slows new supply, which is why the median holds. If you are weighing HVAC against the other licensed trade, the comparisons are electrician vs HVAC technician and electrician vs plumber.
Which one to pick
Pick HVAC if income timing matters, you can sell without hating yourself, and the refrigeration or commercial-specialty road appeals as the ceiling. Pick plumbing if you want a licence, steadier month-to-month demand, and the more paved path to ownership. Both are honest trades; they simply distribute stress differently — HVAC through the year, plumbing through the night.
A three-question self-test
The medians are $2,790 apart, which means the money will not decide this. These three questions usually do.
Question one: how do you feel about commission
Residential HVAC increasingly pays base-plus-incentives, and the gap between a technician who sells maintenance plans and one who does not is larger than any licensing difference. Plumbing pays commission too — service spiffs on repipes and fixtures — but the trade works fine without it. If selling feels like a betrayal of the craft, plumbing is the safer temperament.
Question two: which seasonality can your budget absorb
HVAC income is a summer-weighted curve with a spring dip; budgeting is part of the job. Plumbing’s emergency demand is flatter, and construction plumbing is contract-steady. If your finances need the same number every month, plumbing is the calmer ride. If you can save hard in season, HVAC’s spikes are an opportunity.
Question three: do you want the licence or the speed
The plumber’s four-to-five-year apprenticeship ends in a legal asset; the HVAC certificate ends in a job that starts paying immediately. Neither is strictly better — they price time differently. If you are twenty-two with no dependents, speed is cheap. If you are retraining at thirty-five with a mortgage, the licence’s stability may be worth the years.
Questions people ask before choosing
Four questions decide this comparison for most people. The short answers are below; the sections above have the numbers.
Which pays more, an HVAC technician or a plumber?
At the median, plumber: $63,800 against $61,010 in May 2025, per the Bureau of Labor Statistics — a $2,790 gap that commission structures can reverse for a strong HVAC service tech. Where each trade’s money actually comes from is the more useful question, and both answers are above.
Which is faster to enter?
HVAC, clearly: a six-to-twelve-month certificate and paid helper work almost immediately, against a four-to-five-year plumbing apprenticeship. The counterweight is the licence: the plumber’s years buy a legal moat the HVAC certificate does not. What the certificate actually leads into is in what an HVAC technician actually does all day.
Is HVAC or plumbing more seasonal?
HVAC, by a wide margin: cooling-season peaks, mild-spring troughs, and commission that swings with them. Plumbing has seasonal texture — pipe-freeze calls in winter, renovation cycles in summer — but emergency and construction demand keep the year flat enough to budget. If seasonality is your worry, the trade’s own honest answer is in what a plumber actually does. Still torn? The three-question self-test above settles it.
Which trade is easier to own a business in?
Plumbing, structurally: the contractor licence builds on the journeyman ladder, one van is a genuine business, and emergency demand fills the schedule from day one. HVAC businesses exist at scale and can be very profitable, but the owner competes with manufacturers’ service plans and a more commodified residential market. The ownership ceiling is the plumbing trade’s quiet advantage.
