What it is

This is the map for going from "I'm tired of building somebody else's company" to running your own truck. You already know the trade. What nobody taught you in the field is the order things need to happen so you don't get stuck with a half-built business — licensed but uninsured, insured but with no bank account, busy but unable to take a card. This article is the sequence I wish someone had handed me on day one: decision to first job, in the order that actually keeps you moving.

Read it as the overview. Each piece here — the entity, the license, the insurance, the banking, the startup costs — gets its own deep-dive article in this folder. This one keeps the whole thing in your head at once so you know what comes next.

Why it matters

Most techs who go solo are great at the work and broke by spring. Not because they can't fix equipment — because they treated the business like an afterthought. They quoted off the wage, skipped the insurance to save a few hundred bucks, ran customer payments through their personal checking, and never built a pipeline past their old boss's overflow. The trade pays the bills only if the business behind it is set up right.

Getting the order right also saves you money and re-work. You can't open the right bank account without the entity and the EIN. You can't pull permits without the license. You can't bill a property manager without insurance certificates. Skip a step and you'll circle back, lose a week, and sometimes pay twice.

How to do it (step by step)

1. Make the decision real and check your runway. Before anything legal, look at your money honestly. Going solo means weeks, sometimes months, before steady income. Have a cushion — ideally a few months of personal living expenses plus your startup cash — so you're not forced to take garbage jobs at garbage prices just to eat. This single thing, having runway, is the difference between building a business and panic-pricing your way out of one.

2. Form your business entity. Most one-truck HVAC shops form an LLC. It separates your business from your personal assets and looks legitimate to customers and vendors. You file with your state, pick a name, and it's usually cheap and fast. (See Forming Your HVAC LLC or Business Entity for sole prop vs. LLC vs. S-corp.)

3. Get your EIN and set up the IRS side. An EIN is your business's tax ID — free from the IRS, takes minutes online. You need it to open a business bank account and to hire later. Done at the same time as the entity.

4. Get licensed. This is the one that stops people. HVAC licensing is state-by-state (and sometimes city or county on top), and many places require a mechanical or HVAC contractor license to pull permits and legally do the work. Some require a bond and proof of experience to even sit for the test. Start this early — licensing can take the longest. (See HVAC Contractor License, Bonding, and Insurance.)

5. Buy your insurance. General liability at minimum, workers' comp the moment you have an employee (and sometimes required even for yourself), and commercial auto on the work van. Personal auto won't cover you running a business out of the vehicle. You'll need certificates of insurance to work for property managers, GCs, and warranty companies anyway. (Same article as licensing.)

6. Open a business bank account. Bring your EIN and your entity paperwork. From day one, every dollar in and out of the business goes through this account — never your personal checking. This one habit makes taxes, bookkeeping, and proving your numbers ten times easier later. (See Business Banking and Bookkeeping Basics for HVAC.)

7. Set up how you get paid and how you track money. Pick a way to take cards (customers expect it), and a simple system to log income and expenses from job one. It doesn't have to be fancy — even a clean spreadsheet beats a shoebox of receipts. You'll thank yourself at tax time.

8. Outfit the truck. Gauges, recovery machine, vacuum pump, micron gauge, clamp meter, combustion analyzer, nitrogen, a stocked inventory of common parts. You probably own hand tools already; it's the bigger gear and the van itself that hit the wallet. Buy what you need to work, not everything you might someday want. (See HVAC Business Startup Costs and Funding.)

9. Figure your pricing before you quote anything. Know your true hourly cost — wage, labor burden, truck, overhead — and set a service-call fee and pricing that actually clears a margin. Going in without this is how busy shops go broke. (The Business Operations folder covers true hourly cost, flat-rate pricing, and service-call fees in depth.)

10. Land your first jobs. Set up a free Google Business Profile, work your network hard, ask your old employer for overflow, and ask every happy customer for a review. Add a paid lead channel once you have a little cash to test with. (See How an HVAC Business Gets Its First Jobs in the Getting Work folder.)

What it costs

The legal and administrative side is the cheap part — entity filing, EIN (free), and basic licensing fees often total a few hundred to a couple thousand dollars depending on your state and whether a bond is required. The real money is in the truck and tools and the first stretch of insurance premiums. All in, a lean one-truck startup commonly runs somewhere in the low-to-mid five figures if you already own a usable vehicle, and more if you're buying or wrapping a van. The single biggest hidden cost is the income you're not earning while you set all this up — which is why runway in step 1 matters as much as any line item.

Common mistakes

  • Doing it out of order. Trying to open a bank account before you have an EIN, or bidding work before you're insured. The sequence above exists so you don't stall.
  • Skipping insurance to save money. One liability claim or one injured helper with no comp can end the business and follow you personally. It's not the place to cut.
  • Mixing personal and business money. Running jobs through your personal account turns tax time into a nightmare and weakens the legal protection your LLC is supposed to give you.
  • No pricing math. Quoting off your old hourly wage instead of your true cost as an owner. You now carry the overhead your old boss used to.
  • No cushion. Quitting Friday and expecting a full schedule Monday. The phone takes time to ring.

Tips & gotchas

Start the slow things first. Licensing and insurance underwriting can take weeks; the entity and EIN take a day. Kick off the long-lead items immediately so they're not what holds up your first job.

Keep your old relationships warm. Your former employer's overflow, the plumbers and electricians you know, and your past customers (where you're allowed to work them) are your cheapest, highest-converting first jobs. Don't burn bridges on your way out.

Don't gold-plate the setup. You don't need a logo, a wrapped fleet, and a fancy CRM to start — you need to be legal, insured, payable, and findable. Get to your first job, then improve as money comes in.

Write your numbers down from day one — every job, every expense, every mile. The shop that knows its numbers survives year one; the one that guesses doesn't.

Bottom line

Going solo is a sequence, not a leap: runway, then entity and EIN, then license, then insurance, then a business bank account and a way to get paid, then the truck, then pricing, then customers. Do the slow legal steps first, never mix personal and business money, never skip insurance, and know your true cost before you quote. Get yourself legal, insured, payable, and findable — then go land that first job and let the reviews start building the business you actually own.
