Guide
How to start an HVAC business
Confirm your state license path first, because in HVAC the license is the gate, not the paperwork. Then register the business, get insured, price your flat-rate book off your real hourly cost, and start signing maintenance agreements from job one. The steps in order are below.
| Trade licensing | Most states license HVAC contractors. Your state contractor board publishes the path |
| Federal certification | EPA Section 608 is required for anyone handling refrigerants, in every state |
| Business registration | Your state's Secretary of State |
| Insurance to price in | General liability, workers' comp, commercial auto, tools and equipment |
| Pricing norm | Flat-rate book for service; bid work for installs and change-outs |

Licensing and permit rules change and they change locally; every row above points at the office that publishes the current answer. Our worked-example pack, built for a fictional Kansas City lawn care company, shows the depth your own pack goes to: read it here.
What to do, in order
- 1
Confirm your license path before anything else
Most states license HVAC contractors, usually with experience hours and an exam, and some cities layer their own permits on top. Your state contractor board publishes the requirements. Until you know you qualify, everything else on this list is furniture.
- 2
Get Section 608 squared away
EPA Section 608 certification is federal law for anyone who handles refrigerants, in every state, no exceptions. If you are hiring techs, it is the first line on the job ad.
- 3
Register the business with your state
Registration happens at your state's Secretary of State, usually online in a day or two, and most states require a registered agent with a street address in the state. The current filing fee is on your state's Secretary of State site.
- 4
Get your EIN and open a business bank account
The EIN is free from the IRS, online, usually the same day. The bank will not open a business account without it, and you want every job check running through that account from day one so your books mean something at tax time.
- 5
Get insured like a company, not a guy with a van
General liability, workers' comp the day you have a helper, commercial auto for the van, and coverage on the tools and recovery equipment that live in it. Comp classification for HVAC work is its own line; make sure your policy says what your crew actually does.
- 6
Build your flat-rate book off your burdened hour
Take a wage and add payroll tax, comp, insurance, the truck, and the hours you cannot bill. What comes out is the number you have to beat on every quote. Then build the flat-rate book on top of it, so a capacitor swap or a blower motor is one printed price that already carries your overhead, instead of an hourly rate you discount under pressure at the kitchen door.
- 7
Sell the maintenance agreement from job one
Spring and fall tune-ups are the recurring revenue that flattens the seasons and fills the shoulder months. Every service call ends with the agreement offer. A hundred agreements is a schedulable base; a thousand is a company.
- 8
Go get the first ten customers
Claim the Google Business Profile and get the first reviews fast, because emergency searches go straight to the map pack. Property managers and realtors send steady work to whoever answers the phone. Answer the phone.
The pricing step is the one most people skip. The burdened-rate calculator is free, runs in your browser, and tells you the number you have to beat on every quote.
Where first-year HVAC companies go wrong
Selling hourly in a flat-rate market. Homeowners hate the open meter, and hourly pricing makes your efficiency a discount you give away. A flat-rate book built on your real costs charges for the fix, not the minutes.
Skipping maintenance agreements. Install-only companies ride the weather. Agreements smooth revenue, book the shoulder seasons, and hand you the replacement job years before the unit dies.
Buying the wrapped van before the license clears. The license and the insurance are the business; the wrap is decoration. Spend on what lets you legally take the first job, then let the first jobs buy the paint.
The plan the bank actually reads
Whatever route you take to it, the plan a lender expects has a known shape. This is the table of contents of the business plan in every CrewPlaybook pack, written for your trade and your numbers:

Frequently asked questions
Do I need a license to start an HVAC business?+
In most states yes, through the state contractor board, usually with experience hours and an exam. Some cities add their own permits. Check your state board before you spend anything else.
Can I work on refrigerants without EPA certification?+
No. EPA Section 608 certification is federal law for anyone who handles refrigerants, in every state. Techs carry their own certification.
How much does it cost to start an HVAC business?+
It depends on whether you start service-first with one van or install-first with equipment and a crew. Build your own list and run it against your numbers; the pack's equipment list prices your trade at three budget tiers.
How should I price service calls?+
Flat-rate, built on your burdened hourly cost: wage plus payroll tax, comp, insurance, the van, and unbilled hours. Our free burdened-rate calculator gives you the base number.
What insurance does an HVAC business need?+
General liability, workers' comp once anyone is on payroll, commercial auto for the van, and coverage for tools and recovery equipment. An independent agent who works with contractors can quote all of it in one sitting.
