Figuring out how to start an HVAC business is really two questions: should you leave a technician's paycheck, and what will it cost to open your doors?
The honest data first: most techs stay employees — 68% of HVAC jobs were with plumbing, heating, and AC contractors in 2025 and 6% were self-employed — and no government source prices startup costs or first-year owner income.
This page gives you the framework: what you'd give up, what to price, and when to jump.
Is going out on your own right for you?
Start with the base rates: ownership is the exception in this trade, not the norm.
Of the 440,900 HVAC mechanic and installer jobs counted in 2025, 6% were self-employed and 68% were with plumbing, heating, and air-conditioning contractors.
The large majority of techs collect a paycheck from a shop — so going out on your own is a minority path, and not one to drift into.
What changes when you leave is not the wrench work — it is everything around it.
You become the person who quotes the job, buys the insurance, carries the licence, orders the parts, and waits for the check.
The trade skill that made you a good technician is the entry requirement; it is not the thing that decides whether the business makes money.
So the fit question is really about appetite for that second job.
Do you want to sell, price, and collect — or do you want to turn wrenches and go home?
Some techs run side work first to answer it cheaply: a few weekend jobs, a sense of whether customers call back.
If the selling sounds miserable, owning a shop will be too — a solo owner with no appetite for sales is a technician with extra paperwork.
Startup costs
The honest starting point: there is no government figure for what it costs to open an HVAC business, and our research found no source we could verify one from.
Any single number quoted online is a guess.
The budget that matters is the one you build yourself, category by category, from real quotes in your market.
- A work vehicle — the van or truck, plus racking and parts space. Price this line first; for most solo shops it is the decision the rest of the budget hangs on, whether you buy, finance, or save up for it.
- Tools — if you have been wrenching as an employee, you already own part of the kit, and starting up means completing it. Our breakdown of what tools an HVAC technician needs lists them by stage of your career.
- Insurance — general liability and whatever else applies to you. Get quotes from insurers rather than copying a number from a forum; premiums price your location, your services, and your coverage limits.
- Licence fees — application and exam fees where a contractor licence is required. The board that issues the licence publishes them, so the exact amounts in your budget should come from the board, not from a guide.
- Software and admin — invoicing, scheduling, and accounting tools, plus an accountant at tax time. Cheap monthly, easy to forget, renewed every year.
Keep the one-time lines — vehicle, tools — separate from the recurring ones.
The recurring lines are the ones that catch new owners, because they keep billing you in the months before the phone rings consistently.

Licensing and insurance
Employee rules end and business rules begin at the contractor licence.
States that license HVAC contractors do it through a state board; states that don't push it down a level — Illinois, Indiana, Kansas, and Missouri have no statewide HVAC contractor licence, leaving the rules to cities and counties, and Minnesota requires only a state bond filing plus local licences.
Whichever body issues the licence where you operate sets its requirements — experience, exam, fees — and that licence is the first gate between you and billing customers legally.
The national ladder is covered in our HVAC license guide; for what contractor license requirements look like in practice, see Texas — an example state.
One federal layer sits above all of it: refrigerant work.
Under EPA rules (40 CFR 82.161), anyone who maintains, services, repairs, or disposes of appliances containing regulated refrigerants must pass an exam from an EPA-approved technician certification program — EPA 608.
Being your own boss does not change that; the requirement travels with the work, not the employer.
Insurance is the other half of the paperwork wall.
What you must carry, and in what amounts, depends on where you operate and who your customers are — your insurance agent and the board or local office that issues your licence can both tell you what applies before you quote your first job.
Confirm the rules where you operate before you book work
Pricing and cash flow
Cash flow — not skill — is where new trade businesses wobble.
A startup's money runs backwards: the van, tools, insurance, and licence are paid before the first invoice exists, and customers pay after the work, sometimes slowly.
Your own household bills, the insurance renewal, and the software subscription do not care that the invoice is in the mail.
Demand is seasonal, too.
BLS notes that HVAC technicians sometimes work overtime or irregular schedules during peak heating and cooling seasons — which cuts the other way for a new owner: the shoulder seasons can be quiet.
A shop priced only to survive July will not enjoy January.
So price with the business's full cost in the number.
As an employee, your employer absorbed overhead you never saw — the truck, the insurance, the software, the supply-house account, the advertising.
Your price as an owner now carries all of it, plus your pay.
The number worth knowing before you resign is what a job must bill for the business to clear money after every cost — and it comes off your own quotes and cost list, not a benchmark.
Then collect.
A shop can look profitable on paper and still be broke at the bank.
Deposits on larger jobs, invoicing the day work closes, and plain written terms are boring disciplines that keep the doors open through the ramp-up.
Income in the first three years
Set expectations honestly: no government series follows what a brand-new HVAC business nets in its first three years, and no government source prices HVAC owner income by business size at all.
The "average first-year owner income" tables that circulate are built from sources that cannot be checked.
What the verified data gives you is the benchmark you would be stepping away from, and one cautionary federal average.
The benchmark: HVAC mechanics and installers earned a $61,010 median nationally in May 2025, and $60,030 within plumbing, heating, and air-conditioning contractors.
The middle half of employees earned between $48,360 and $77,060, with the 90th percentile at $95,210.
Those figures are employees only — BLS wage data excludes the self-employed entirely — so they are what the market pays for your labor when somebody else carries the business risk.
| Benchmark | Figure | Source |
|---|---|---|
| National median, HVAC mechanics and installers (employees) | $61,010/yr | BLS OEWS, May 2025 |
| Median at plumbing, heating, and AC contractors | $60,030/yr | BLS OEWS, May 2025 |
| Middle half of employees | $48,360–$77,060/yr | BLS OEWS, May 2025 |
| Average net per specialty-trade sole-proprietor return | about $16,050 | IRS SOI, tax year 2023 |
The cautionary average is the last row.
The closest federal figure to "solo trade business income" is the IRS tally of sole-proprietor returns across all specialty trades — 2,521,516 returns in tax year 2023, averaging about $16,050 in net income each.
Read it with its own caveats: it mixes every specialty trade, includes part-time and side-business filers, and excludes S-corps and partnerships.
It understates what a full-time shop owner nets, and it is not a forecast — new shops can land below it, or lose money.
The honest mechanism sits between those numbers: your income as an owner is billings minus every cost, and the three-year path is whatever your prices, your costs, and your market make it.
Plan the early years around the cash the business keeps, not the revenue it books.

When to make the jump
The market is not the question — you are.
BLS projects HVAC mechanic and installer employment to grow 10.9% from 2025 to 2035, much faster than the 3.5% all-occupation average, with about 40,600 openings a year.
Demand will not be what stops a competent, licensed tech from finding work.
What stops new shops is running out of cash before the book of work fills in — so the timing question is about your runway, not the industry.
- Work is lined up — customers who have said yes, not leads you might quote later
- Cash covers both sides: your household's living costs and the business's overhead, for the ramp-up period you have chosen before resigning
- The contractor licence where you operate is issued — or you know exactly what stands between you and it
- You have priced replacing what your paycheck never showed: BLS wage figures exclude employer-paid benefits, so the job you're leaving is worth more than its wage number
Sequence beats courage: licence, then customers, then cash, then the resignation letter — in that order.
Reversed, the order is expensive.
And you do not have to stay a one-person shop forever; when the calendar fills past what your own hands can serve, the next decision is hiring your first tech, which changes the arithmetic again.
