How to Start an HVAC Business in 2026 (Costs, Licenses and First Customers)

How much does it cost to start an HVAC business?

More than a cleaning or handyman start, mostly because of the van and the refrigerant tools. Most new HVAC owners are working techs who already own hand tools and a truck, which cuts the bill a lot. In our example, filling out a service kit, licensing, launch marketing and three months of fixed costs come to $16,503 with your own truck. Buying a full kit and a used service van takes it to $58,503. Insurance (Insureon) and the service-call price (Housecall Pro) are cited; the rest are illustrative, so replace them with your own supply-house quotes.

What licenses do you need to start an HVAC company?

Two layers: a federal certification for refrigerant, and a contractor license from your state or city. The first is the same everywhere. The second varies a lot. The BLS notes that only some states and localities license HVAC technicians, while many states license the business that contracts for the work.

EPA 608: required everywhere

Under Section 608 of the Clean Air Act, the EPA requires certification for technicians who maintain, service, repair or dispose of equipment that could release refrigerant. Attaching gauges, adding or removing refrigerant, or opening the system all count. There are four certification types: Type I for small appliances, Type II for high-pressure systems (most residential AC and heat pumps), Type III for low-pressure systems, and Universal for all three. EPA says 608 credentials don't expire, and that an open-book Core test can't be used toward Universal. Apprentices are exempt only while closely and continually supervised by a certified tech.

For an owner, the sales restriction matters as much as the work rule: only EPA-certified technicians can buy refrigerant, with limited exceptions. No card, no supply-house refrigerant. If you're still studying, start with our free EPA 608 Core practice test and the EPA 608 certification guide.

State and local HVAC contractor licenses

California's handyman exemption won't cover side HVAC work: the CSLB's $1,000 minor-work rule only applies when no permit is needed and you have no employees on the job, and many cities require a permit for an equipment changeout. Ask your building department. Running jobs without the license your state requires puts your insurance, your ability to pull permits and your manufacturer warranty registrations at risk.

From technician to owner

Most HVAC owners were techs first. The BLS puts the median HVAC mechanic and installer wage at $61,010 (May 2025), with 440,900 jobs and 11% projected growth from 2025 to 2035. That pay is the bar your business has to beat after costs. The skills that make you a good tech (diagnosis, brazing, airflow) carry over. The ones that usually don't are pricing, answering the phone while you're on a roof, and keeping books.

• Get your hours documented now. Texas wants experience verification forms signed by the contractor who supervised you. Ask before you give notice, not after.
• Finish the technical gaps. Our HVAC track covers the fundamentals, including superheat and subcooling and the R-454B PT chart for A2L systems.
• Know the rule changes. Follow refrigerant news like the R-410A installation deadline change before you stock equipment.
• Read your non-compete. Some employment agreements limit soliciting your old shop's customers. Get it reviewed if you signed one.

What equipment does a new HVAC business need?

Buy the tools that let you diagnose and close out a repair on the first visit. A second trip for a part you could have carried kills both the margin and the review.

• Refrigerant tools. Recovery machine and tanks, vacuum pump, digital manifold, micron gauge, scale and an electronic leak detector.
• Electrical diagnostics. Clamp meter with capacitance, a non-contact tester, a spare set of leads.
• Brazing and nitrogen. Torch kit, nitrogen regulator and flow meter. Flowing nitrogen while brazing is cheaper than a callback.
• Airflow and combustion. Manometer and, if you service furnaces, a combustion analyzer.
• Truck stock. Universal capacitors, contactors, igniters, flame sensors, fuses, filters and common refrigerants your local systems use.
• Safety. Gloves, glasses, a fire extinguisher and ladder stabilizers. Keep A2L handling guidance with the gear if you install newer systems.

How do you price HVAC service calls and installs?

Charge a diagnostic fee, price repairs flat from a price book, and quote installs as packages. Hourly billing on repairs makes you compete on rate; flat pricing lets the customer approve a known number before you start. Tune-ups are your loss leader into maintenance agreements, which keep the shoulder seasons busy.

1. Build a flat-rate book. The flat rate pricing calculator turns your labor rate, parts cost and target margin into a price per task. See flat-rate pricing.
2. Price the changeout. The job pricing calculator has a 3-ton condenser replacement preset to start from.
3. Sell the agreement. The maintenance agreement calculator shows what 100 members are worth a year.
4. Mind the margin. A 50% markup on equipment is a 33% margin. Check markup vs. margin before you match a competitor's bid.

How do you get HVAC customers when you're new?

HVAC demand comes in waves: the first heat wave and the first cold snap flood the phones, then it goes quiet. New owners win by being reachable on the busy days and by turning those calls into agreement customers for the quiet ones.

1. 1

   Get on the map.

   A complete Google Business Profile with your service area, hours and real van photos is free, and it's where "AC repair near me" lands.

2. 2

   Consider Local Services Ads.

   Google's pay-per-lead ads show a license and insurance check badge. Read Google Local Services Ads for HVAC before you spend.

3. 3

   Call the people you've served.

   Former customers who asked for you by name may follow you, unless your agreement with your old shop says otherwise. Builders and property managers need a reliable sub.

4. 4

   Be the one who answers.

   On a 100-degree day, the shop that picks up gets the job. Use a call script and see what voicemail costs with the missed call calculator.

5. 5

   Turn every visit into a member.

   Offer a maintenance agreement at every tune-up and repair. Members call you first and fill your spring and fall.

Lead marketplaces work for some new shops, but you pay whether the lead books or not. Ask every caller how they found you and track your cost per booked job. More ideas are in how to get more HVAC customers.

Your launch tech stack

An HVAC shop runs on dispatch: calls in, a tech on site, a quote approved, a payment taken. On a one-truck shop you're the CSR, dispatcher and tech. Before the first hot week, set up a business line that's covered after hours, a calendar customers can book into, a price book on your phone, card payments and books that track job profit.

Is an HVAC business profitable?

It can be one of the better-paying trades to own, because a single replacement is worth weeks of service calls. There's no reliable public number for first-year owner income, so build your own: service calls per week, closing rate on repairs, changeouts per month, and agreement members, against your fixed costs and the wage you'd earn as a tech. Seasonality is the main risk. Plan cash for the shoulder months.
