How to Start an HVAC Business: Tech-to-Owner Playbook (2026)

Plenty of good techs think about going out on their own. Being great at diagnosing a system and running a profitable shop are different skills, though. Most of what goes wrong for new owners isn't technical. It's pricing too low, skipping the paperwork, running out of cash in the slow season, or not knowing their numbers.

This playbook walks through the steps in order: licensing, business setup and insurance, startup costs, pricing, getting customers, maintenance agreements, first hires, and the numbers to watch. Where we cite a number, it links to where it came from. Where we don't have a sourced number (for example, what it costs to start a shop in your area), we say so rather than guess.

This is general information, not legal, tax, or insurance advice. Rules vary by state, county, and city. Check with your state licensing board and talk to an accountant, attorney, and insurance agent before you commit.

Step 1: Know the market you're walking into

The trade is growing. The BLS projects employment of heating, air conditioning, and refrigeration mechanics and installers to grow 11% from 2025 to 2035, much faster than the average occupation, with about 40,600 openings projected per year. There were 440,900 of these jobs in 2025, and the median pay was $61,010 per year ($29.33 per hour) in May 2025. The same page lists 6% of HVAC mechanics and installers as self-employed. Source: BLS Occupational Outlook Handbook, "Heating, Air Conditioning, and Refrigeration Mechanics and Installers"

Two things follow from that. Demand for the work is there. But the same shortage that makes your skills valuable will make it hard to hire once you grow, so plan for that early (Step 8).

One honest gut-check before you start: that median wage is roughly what you'd give up in steady paychecks. Your shop needs to pay you at least a fair wage for your own labor plus a profit on top. If the plan only works when you work for free, it isn't a plan yet.

Step 2: Get your certifications and licenses in order

EPA Section 608 certification (federal). The EPA requires certification for "technicians who maintain, service, repair, or dispose of equipment that could release refrigerants." There are four types:

• Type I: servicing small appliances
• Type II: servicing or disposing of high- or very high-pressure appliances (except small appliances and motor vehicle AC)
• Type III: servicing or disposing of low-pressure appliances
• Universal: all types of equipment

Section 608 certifications don't expire once earned. If you're going to run residential and light commercial work, most owners get Universal so there's no gap in what they can service. Source: EPA, "Section 608 Technician Certification Requirements"

State and local contractor licensing. This is where it varies most. The BLS notes that "some states and localities require HVAC technicians to be licensed; check with your state and locality for more information." Source: BLS Occupational Outlook Handbook Some states license HVAC contractors at the state level, some leave it to counties or cities, and many require proof of experience, an exam, insurance, and sometimes a bond before you can pull permits or advertise. The SBA's advice is to check your state, county, and city requirements, and start with your Secretary of State's website. Source: SBA, "Apply for licenses and permits"

Practical tip: call your state contractor licensing board and your local building department and ask directly: "What do I need to legally run HVAC service and replacement jobs here, and to pull permits in my own business name?" Write down the answer and who told you.

Step 3: Set up the business (entity and insurance basics)

Business structure. The SBA's business-structure guide lays out the main tradeoff:

• Sole proprietorship: simplest to set up, but "you can be held personally liable for the debts and obligations of the business."
• LLC: in most situations, owners are not personally liable, so personal assets like "your vehicle, house, and savings accounts" aren't on the line if the LLC faces bankruptcy or lawsuits.
• Corporation: the strongest protection from personal liability, with more paperwork and tax complexity.

The SBA also notes that "consulting with business counselors, attorneys, and accountants can prove helpful" when choosing a structure, since changing later can have tax consequences. Source: SBA, "Choose a business structure"

Insurance. The SBA describes general liability coverage as protection "against financial loss as the result of bodily injury, property damage, medical expenses, libel, slander, defending lawsuits, and settlement bonds or judgments." It also lists workers' compensation, unemployment, and disability insurance as required for businesses with employees, and notes that "laws requiring insurance vary by state." Source: SBA, "Get business insurance" For an HVAC shop, also ask your agent about commercial auto for your truck, tools and equipment coverage, and any bond your license requires.

Separate the money on day one. Open a business bank account and run every job through it. It makes taxes easier, and it's the only way you'll be able to see your real numbers later (Step 9).

Step 4: Price out your startup costs

We don't have a sourced national number for what it costs to start an HVAC business, and the totals floating around online rarely say where they came from. The honest answer depends on whether you already own a truck and tools, your state's licensing and bond requirements, and your local insurance rates. What we can do is put published prices on the lines that have them, and flag the ones you have to quote locally.

How to read the table:

• The insurance figures are medians, not quotes. Insureon says its numbers are "the median cost of policies for HVAC installation companies that apply for quotes with Insureon," and that most of those customers have fewer than five employees and five years or less in business. Your price depends on your state, driving record, limits, and claims history.
• Software prices are list prices from each vendor's pricing page as of this writing. Extra users, payments, and add-ons cost more. Our field service software comparison goes deeper.
• Count a full year of monthly costs, not just the one-time ones. The SBA's guidance is to separate one-time from monthly expenses and to "count at least one year of monthly expenses." Source: SBA, "Calculate your startup costs"

That last row, the cash reserve, is the one that sinks new shops. HVAC is seasonal, and customers and suppliers don't always pay on your schedule. For the personal side of it (how much to save, when to quit your job, and how to watch cash in the first 90 days, with a worked example), see From HVAC Tech to Shop Owner: Runway, Timing, and Your First 90 Days. To add up your own numbers month by month for the first year, use the free HVAC startup cost & first-year cash calculator.

Step 5: Price your labor so the business actually makes money

New owners often set their rate by looking at what the shop they left charges, or by guessing what customers will accept. Both skip the real question: what does your hour have to cost to cover your overhead, your own pay, and a profit?

Two things to know before you set a number:

• Not every paid hour is billable. Drive time, estimates, parts runs, and office work all eat into your day. Your rate has to be built on billable hours, not a 40-hour week.
• Overhead is spread across those billable hours. Insurance, truck payments, fuel, phone, software, and marketing all have to be paid from what you bill.

Do the math with your own numbers in the free HVAC break-even hourly rate calculator, then turn that rate plus parts into task prices with the flat-rate price calculator. Whether to price by the task or by the hour is covered, with sourced profit comparisons, in our flat-rate vs. time-and-materials pricing guide.

Step 6: Get your first customers

Your first customers usually come from people who already know your work: past customers who trusted you as their tech (where your prior employment terms allow it), friends and family, neighbors, and referrals from other trades. Beyond that, the usual starting moves:

• Google Business Profile. Free, and it's what shows up when someone searches "AC repair near me." Fill it out fully and ask every happy customer for a review.
• A simple website. Service area, services, phone number, and a way to book.
• Trade referrals. Plumbers, electricians, and property managers run into HVAC problems all the time.
• Paid ads, later and carefully. Paid leads aren't cheap. Before you spend, work out what you can afford to pay per lead with the cost per lead guide.

Track where every lead came from from the first call, and whether it turned into a paying job. That tells you which channels to keep paying for.

Step 7: Offer a maintenance agreement from month one

A new shop's biggest problem is uneven work: slammed in peak season, quiet in the shoulder months. Maintenance agreements give you scheduled work to fill slow weeks and a base of customers who call you first. Start offering a plan from your first month, and price it so it pays for the visits it promises. The maintenance agreements guide covers plan design, and the free maintenance agreement calculator checks whether your price covers your costs.

Step 8: Make your first hire

Most owners hire when they're turning away work or when they physically can't do both the jobs and the office. Common first hires are a second tech or helper (to add billable capacity) or part-time office help (to answer the phone and schedule, freeing you to be billable). Before you hire, know the loaded cost (payroll taxes, workers' comp, benefits), not just the wage; the free labor burden calculator does that math. For pay and retention, see the hiring and retention guide and HVAC technician pay by state.

Step 9: Track your numbers from month one

A spreadsheet with one row per month is enough to start. Begin with average ticket, close rate, gross margin, and net profit (counting a fair wage for yourself as a cost), then add more as you grow. Formulas, published benchmarks, and a monthly scorecard are in the HVAC KPIs guide.

Startup checklist, in order

The order matters because some steps can't start until another is done. You can't pull permits without the license, and most insurers and banks will want the entity and EIN first.

Phase 1: Before you quit

1. Confirm your state and local license requirements in writing, and count your documented experience months.
2. Pass EPA Section 608 (Universal if you'll service everything).
3. Read your employment agreement for non-compete, non-solicitation, and outside-work terms.
4. Work out your runway and start saving (runway guide).
5. Apply for the contractor license and schedule the exam.

Phase 2: Set up the business (once the license is in sight)

1. Choose a business structure with an accountant or attorney, and file it.
2. Get an EIN from the IRS (free).
3. Open a business bank account.
4. Get insurance quotes; bind general liability, commercial auto, and tools coverage, plus any bond your license requires.
5. Open supply house accounts and ask about payment terms.
6. Set up scheduling, invoicing, and payments software.

Phase 3: Open for business

1. Build your hourly rate and price book from your own costs.
2. Launch your Google Business Profile and a simple website.
3. Create a maintenance plan to offer from the first job.
4. Start the monthly numbers spreadsheet.

Phase 4: Before your first hire

1. Get workers' comp in place and know the loaded cost of the role.
