How to Start an HVAC Business (2026)

Heating and air-conditioning contractors in the US are a $159.4 billion market in 2026, according to IBISWorld. That is a huge, boring, recession-resistant pile of money, and most of it flows to small shops running one or two trucks.

Plenty of good techs make the jump to owner and then stall out on paperwork, pricing, or cash flow. So what does it actually take to open your own HVAC business and keep it alive past year one?

Key takeaways

• Two credentials are non-negotiable before you touch a compressor: EPA Section 608 certification (a federal rule under the Clean Air Act) and whatever HVAC license your state requires.
• Realistic startup costs run roughly $20,000 to $80,000, driven mostly by the van and specialty tools, based on current industry startup guides.
• HVAC/R mechanics earned a median wage of $59,810 in May 2024 (BLS), which is roughly the ceiling you are trying to break past by owning the truck instead of driving it.

Do you need a license and EPA 608 certification?

Yes, and they are two separate things. EPA Section 608 certification is federal. Under the Clean Air Act it is a precondition for buying refrigerant and servicing almost any AC, refrigeration, or heat-pump system (EPA). State licensing is separate and varies a lot.

Some states license HVAC contractors tightly. Others hand it to counties or barely regulate it.

The EPA 608 part

There are four flavors. Type I covers small appliances. Type II covers high-pressure systems, which is most residential and light-commercial AC. Type III covers low-pressure chillers. Pass all three plus the core and you get Universal, which is what most owners carry.

The certification never expires. Exam fees are cheap, usually in the $25 to $150 range depending on the provider and whether you test in person, per training providers like Interplay Learning and the ESCO Institute.

The state license part

This is where people get burned. A few states let anyone with a truck pull permits. Others require years of documented field experience, a passed trade exam, and proof of insurance before they issue a contractor license.

Call your state licensing board before you spend a dollar on branding. The rules where you live decide your timeline more than anything else on this page.

How much does it cost to start an HVAC business?

Budget somewhere between $20,000 and $80,000 to open the doors, according to current startup guides from Workiz and Smart Service. The two line items that swing the number hardest are your vehicle and your tools. Everything else is smaller and more predictable.

The van and the tools

A used cargo van or pickup runs about $10,000 to $30,000 depending on age and miles. A new work van base starts closer to $40,000 to $60,000. Buy used for your first truck.

For tools, a lean hand and power-tool kit runs $5,000 to $15,000, and the specialty gear that makes you an HVAC tech and not a handyman (refrigerant recovery machine, vacuum pump, manifold gauges, leak detector) adds another $2,000 to $8,000, per the same startup guides.

Do not skimp on gauges and a recovery machine. Cheap ones cost you jobs.

What business setup and insurance do you actually need?

Form an LLC, get an EIN, open a separate business bank account, and buy real coverage before your first job. HVAC contractor insurance runs an average of $78 a month for general liability alone, per TechInsurance.

Skipping coverage to save a few hundred dollars is how one bad install ends the whole business.

General liability is the floor. Add commercial auto for the van (about $2,292 a year on average) and workers compensation once you hire, which averages about $2,672 a year and is legally required in most states the moment you have an employee (TechInsurance).

Many states or municipalities also want a surety bond before they issue your contractor license. That is not insurance for you. It protects the customer, and the license board sets the amount.

How should you price and estimate jobs?

Stop pricing off gut feel. Your rate has to cover your billable hours, your overhead, and profit on top, because a tech only sells maybe 1,200 to 1,500 billable hours a year after drive time and slow weeks.

Since the median HVAC wage sits near $59,810 (BLS), your shop rate needs to clear far more than that per productive hour just to pay yourself and keep the lights on.

Two models dominate. Flat-rate pricing quotes one number per task from a price book, which customers like and which protects you when a job runs long. Time-and-materials bills hours plus parts, which fits big installs and messy diagnostics.

Most one-truck shops run flat rate for service calls and switch to itemized quotes for installs. Whatever you pick, build a real price book and stop discounting to win every call.

How do you land your first customers?

Your first ten jobs come from people who already trust you, not from ads. Ask former coworkers, past customers if your old boss allows it, and every plumber or electrician you know for referrals. Then set up the free stuff that ranks.

A Google Business Profile is the single highest-return marketing asset for a local HVAC shop, and it costs nothing.

Get listed, get reviews, and answer the phone. Speed to lead wins in this trade. The homeowner with no heat calls four companies and hires whoever picks up first.

After referrals dry up, a simple website, seasonal tune-up offers, and a maintenance plan that bills monthly give you recurring revenue that smooths out the slow shoulder seasons.

What software runs an HVAC business?

One field-service platform can replace the paper invoices, the whiteboard schedule, and the shoebox of receipts. The category is crowded, so match the tool to your size. A solo tech and a 20-truck shop need very different things, and overbuying here is a real money leak.

For a lean launch, Jobber is the usual starting point, with plans that start at $39 a month for one user on annual billing (Jobber). Housecall Pro is the other small-shop favorite, with strong consumer-facing booking and a Basic plan around $59 a month.

Workiz leans into call tracking and dispatching and offers a free entry tier, which is handy when cash is tight.

When you scale into multiple crews and want deep reporting, ServiceTitan is the enterprise pick, though it is quote-only and third-party sources like TrustRadius report roughly $125 to $398 per tech per month.

HVAC business startup FAQ

How much do HVAC business owners make?

Owner pay varies wildly by how many trucks you run and how well you price. As a benchmark, employed HVAC/R mechanics earned a median of $59,810 in May 2024, with the top 10 percent above $95,210 (BLS).

The point of ownership is to build a shop that pays you well above that once it is running crews.

Do I need to be EPA 608 certified to buy refrigerant?

Yes. EPA Section 608 certification is a federal precondition for purchasing refrigerant and servicing most AC and refrigeration equipment under the Clean Air Act (EPA). The certification does not expire once earned, and Universal certification covers all system types you will realistically touch as a residential and light-commercial contractor.

How big is the HVAC market?

Heating and air-conditioning contractors form a $159.4 billion US market in 2026, and it has grown at a 2.6 percent compound annual rate since 2021 (IBISWorld). Demand is steady because heating and cooling are not optional. That stability is a big reason the trade survives downturns better than most.

Should I start solo or hire right away?

Start solo if you can. Payroll is your biggest fixed cost, and workers compensation alone averages about $2,672 a year per the TechInsurance data. Prove you can fill a schedule and price jobs profitably first. Hire your first tech only when you are turning away work you could have billed.

The bottom line

Starting an HVAC business is less about wrenching and more about the boring stuff: the right EPA and state credentials, a used van instead of a new one, real insurance, and a price book you actually follow.

Expect to spend $20,000 to $80,000 and to grind through referrals before ads ever pay off. Get one software platform in place from day one so the paperwork does not bury you while you are trying to build a book of business.
