If you’re wondering how to start an HVAC business, you’re probably already the “go-to” tech everyone calls when their AC dies in July. Turning those calls into a real company is totally doable—but it takes more than buying a van and slapping your name on the side.
Below is a clear, practical roadmap based on what top HVAC business guides and industry resources recommend, plus some real-world numbers so you’re not guessing your way through it.
Is starting an HVAC business actually worth it?
Before you learn how to start an HVAC business, you need to know if the opportunity is real. Short answer: yes—if you treat it like a business, not just a job with a logo.
Industry research shows the global HVAC market is projected to reach about $367.5 billion by 2030, with steady growth driven by construction, retrofits, and stricter efficiency standards. That means ongoing demand for installs, replacements, and maintenance—not just seasonal work.
On the flip side, it’s not a “zero-cost” side hustle. Lean HVAC startups typically spend around $10,000–$50,000 on tools, a reliable vehicle, licensing, insurance, and early marketing, and costs can climb toward $100,000 if you go bigger from day one. Knowing that range helps you decide whether you’ll bootstrap slowly or seek financing.
What skills and certifications do you need first?
You shouldn’t be figuring out basic troubleshooting while running a company. Most top-performing owners work as HVAC techs or crew leads before launching their own shop. Guides from Jobber, FreshBooks, and others all stress getting several years of hands-on experience first.
In the U.S., if you work with regulated refrigerants, you (and any techs you hire) must hold EPA Section 608 certification. It’s a federal requirement under the Clean Air Act for anyone who services, installs, or disposes of equipment containing refrigerants. You can earn Type I, II, III, or Universal depending on what systems you handle, and this credential does not expire.
Alongside technical skills, successful HVAC owners also build:
- Strong customer communication
- Basic sales skills (explaining options, selling maintenance plans)
- Business skills like pricing, estimating, and scheduling
That combo is what turns you from “great tech” into “profitable owner.”
What licenses and permits do you need when learning how to start an HVAC business?
Here’s where a lot of good techs stall: paperwork. But you can’t skip it.
Most U.S. states and many cities require an HVAC contractor license to operate legally. Often, that means meeting experience requirements, passing an exam, and proving you have liability insurance and sometimes a bond.
On top of that, you’ll typically need to:
- Choose a business structure (often an LLC for liability protection)
- Register your business name with the state
- Get an EIN from the IRS for taxes and payroll
- Obtain any local business licenses from your city or county
Because licensing rules vary widely by state, always check your state’s contractor licensing board or a resource like Wolters Kluwer’s HVAC license guide to confirm exactly what’s required where you plan to work.
How do you build a business plan and realistic startup budget?
Every serious “how to start an HVAC business” guide emphasizes one thing: write a business plan before you spend big money.
A solid HVAC business plan usually covers:
- Services: Will you focus on residential, commercial, new installs, or maintenance contracts?
- Target market: Which neighborhoods, cities, or industries will you serve?
- Operations: Number of trucks, staffing plan, hours, and service radius
- Marketing strategy: Website, local SEO, Google Business Profile, referrals, and partnerships
- Financials: Startup costs, pricing structure, monthly overhead, and revenue projections
On costs, you’ll budget for:
- Tools & equipment: Basic HVAC tool setups can run $1,500–$3,000, and more advanced gear can push that higher.
- Vehicle: A dependable van or truck (owned or financed).
- Insurance: Median general liability premiums for HVAC contractors are around $55/month (~$662/year), and you may also need workers’ comp, commercial auto, and property coverage as you grow.
- Licensing & fees: State license fees, local permits, and possibly bonding.
- Marketing & software: A professional website, scheduling/dispatch software, and CRM or invoicing tools.
Write it all down. Lenders and investors love it, and it keeps you from underpricing or overspending in your first year.
How do you market and grow your new HVAC business?
Once you’re legal and equipped, you need the phone to ring consistently. The best-performing HVAC business guides all point to a mix of online and offline tactics.
Key moves include:
- Local SEO: Build a clean website that clearly states your services and service area. Optimize for phrases like “AC repair near me” or “furnace installation [city].”
- Google Business Profile: Set it up, add photos, list services, and actively request reviews from happy customers.
- Partnerships: Network with realtors, builders, and property managers who can send you steady work.
- Maintenance plans: Offer service plans that include seasonal tune-ups. They create recurring revenue and deepen customer loyalty.
As you grow, keep refining pricing, tracking job profitability, training your team, and monitoring safety and compliance with OSHA and EPA rules for refrigerant handling and disposal.
Frequently Asked Questions
1. How much does it cost to start an HVAC business?
Most lean startups can get rolling in the $10,000–$50,000 range, covering tools, a vehicle, licensing, insurance, and basic marketing. If you’re opening a shop, buying multiple trucks, or hiring several techs right away, your budget can easily approach $100,000 or more. Start by listing what you already own (tools, truck, office space) vs. what you must buy, then build a budget around that instead of guessing.
2. Do I need EPA 608 certification to own an HVAC company?
To own the business, not necessarily. But anyone who handles regulated refrigerants—including you if you work in the field—must hold EPA Section 608 certification. That means you either get certified yourself or only hire techs who are certified. From a practical standpoint, most owners who work in the field get Universal 608 so they can service any system legally and confidently.
3. How long does it take to start an HVAC business?
If you already have experience and your state licensing process is straightforward, you might go from planning to taking your first paid job in a few months. You’ll need time to pass any exams, apply for contractor and business licenses, set up your LLC, secure insurance, and build basic marketing assets like a website and Google Business Profile. The more organized you are upfront, the faster this goes.
4. Can I start an HVAC business as a one-person operation?
Yes. Many successful HVAC companies started as a single tech with one truck. You’ll wear every hat at first: technician, dispatcher, bookkeeper, and salesperson. Over time, you can hire office staff, additional techs, and helpers as cash flow grows. Just make sure your pricing covers not only your labor and materials but also overhead and future hires so you’re building a sustainable business—not just buying yourself another stressful job.
