How to Start an HVAC Business
HVAC is one of the higher-earning trades and one of the more regulated, so starting a business means clearing licensing and certification first, then building a mix of service calls and installs. The payoff is strong, recurring demand. Here is the path.

Is a HVAC business worth starting?
HVAC pays above most trades and is projected to keep growing as systems age and electrification expands, so the demand is durable.
What do HVAC jobs cost? See HVAC pricesHow much does it cost to start?
A typical HVAC business costs $10,000 to $50,000 to start. Tools, a service van, refrigerant equipment, licensing, and insurance make HVAC more capital-intensive than most trades. Many owners start solo from an existing tech background.
| Startup cost | Typical range |
|---|---|
| Tools + gauges + recovery equipment | $3,000 to $10,000 |
| Service van | $5,000 to $40,000 |
| Licensing + EPA 608 + exams | $500 to $3,000 |
| Liability + commercial auto insurance | $2,000 to $6,000 / year |
| Software, marketing, website | $500 to $3,000 |
Ranges are typical and vary by market and scope. Confirm licensing costs with your state.
How much can you earn?
HVAC technicians earn a median around $61,000 as employees; owners of a healthy service-and-install shop clear $100,000 to $250,000 or more once they have steady maintenance agreements and a tech or two. It is one of the highest-earning trades.
How to start a HVAC business, step by step
- 1
Get licensed and certified
Most states require an HVAC contractor license (often after documented experience and an exam). Federal EPA Section 608 certification is required to handle refrigerant. Many owners come up as techs first, then get licensed to run their own shop.
- 2
Set up the business and insurance
Form an LLC, get an EIN, and carry general liability plus commercial auto for your van. If you hire techs you will also need workers' comp. Bonding may be required for some commercial or new-construction work.
- 3
Equip a service van
A reliable van stocked with tools, gauges, a recovery machine, and common parts is your shop. Keep frequently used parts and capacitors on the truck so you can close calls in one visit.
- 4
Decide service vs. install mix
Service and repair calls have fast cash flow and lead to replacements; installs are bigger tickets but longer sales cycles. Most new shops lean on service and maintenance agreements, then grow into installs.
- 5
Win the first customers
A Google Business Profile, fast emergency response, and relationships with property managers, realtors, and general contractors. Maintenance agreements (spring/fall tune-ups) create recurring revenue and a pipeline of replacement work.
- 6
Dispatch and invoice without the chaos
Same-day estimates, scheduling and dispatch that keep techs moving, parts and time tracking per job, and invoicing with online payment are what make an HVAC shop profitable instead of just busy.
Licensing and insurance
EPA Section 608 certification is federal and non-negotiable for anyone handling refrigerant, which is nearly every job you will do. Most states then license HVAC contractors separately, typically after documented experience and an exam, and you will need a bond and insurance to pull permits. A handful of states regulate at city level instead, so confirm locally rather than assuming the state rule covers you.
How to price your work
Service calls commonly carry a diagnostic/trip fee ($75 to $150) plus labor; repairs are flat-rate or hourly. System installs range widely ($5,000 to $12,000+) by equipment and home. Maintenance agreements (often $150 to $300 per year) lock in recurring revenue and replacement leads.
| Service | Typical price |
|---|---|
| Service / diagnostic call | $75 to $150 |
| Repair (flat-rate) | $150 to $600 |
| Maintenance agreement (annual) | $150 to $300 |
| System install | $5,000 to $12,000+ |
| Emergency / after-hours | premium |
Example prices are typical U.S. ranges and vary by region, scope, and demand.
Pros and cons of starting a HVAC business
Pros
- Among the highest-earning trades
- Durable, recurring demand (aging systems + electrification)
- Maintenance plans create recurring revenue and replacement leads
- High barrier to entry keeps out casual competition
Cons
- - Heavily regulated (license + EPA 608 required)
- - Capital-intensive (van, tools, refrigerant equipment)
- - Hard to start without prior experience
- - Seasonal demand spikes strain a solo operator
Common mistakes to avoid
- Starting without the required license and EPA 608 certification
- Underpricing installs that carry warranty and callback risk
- Not selling maintenance agreements (the recurring-revenue engine)
- Driving back to the shop for parts instead of stocking the van
What year one actually looks like
The parts of HVAC work nobody warns you about, which show up once you have customers rather than while you are deciding whether to start.
Lead times sit between the sale and the install
A signed replacement is not a completed job until the equipment arrives, and a particular size or efficiency can be weeks out. During a heat wave that gap is when customers get impatient and call somebody with a unit on the shelf, so what your supplier has in stock shapes what you sell.
Being on call means your evenings are inventory
Premium after-hours rates exist because someone has to be reachable whether or not the phone rings. Once you sell that availability you have sold your evenings, and deciding when you are genuinely off becomes a business decision rather than a personal one.
Every maintenance agreement you sell is a visit you owe
Two hundred tune-ups sold is two hundred appointments that have to happen inside two narrow windows, with reminders, access arrangements and reschedules. The recurring revenue is real and so is the delivery obligation, and the second half surprises people.
Run it like a business from day one
The operators who pull ahead in any trade are the ones who systematize the boring parts, meaning booking, scheduling, invoicing, payments and reviews. Smarfle is the all-in-one CRM built for HVAC operators, so you can take on more work without drowning in admin.
Frequently asked questions
How much does it cost to start an HVAC business?+

What license do you need to start an HVAC business?+
Most states require an HVAC or mechanical contractor license (often after documented experience and an exam), and federal EPA Section 608 certification is required to handle refrigerant. Check your state board and the EPA.
Is an HVAC business profitable?+
Yes, HVAC pays above most trades (about a $61,000 median tech wage) and demand is projected to keep growing. Profit comes from a healthy service-plus-maintenance base that feeds higher-ticket installs.
How do I get HVAC customers?+
A Google Business Profile, fast emergency response, and referral relationships with property managers, realtors, and general contractors. Spring and fall maintenance agreements build recurring revenue and replacement leads.
