How to Start a HVAC Business
in 2026

Get Licensed, Certified, and Properly Insured

HVAC is a licensed trade in almost every state. You cannot legally work without the right credentials — and clients will ask.

• EPA 608 Certification — Federal requirement to purchase and handle refrigerants. Universal type covers all systems. Exam costs $20–$75 at ESCO Institute or local HVAC distributor. Study time: 1–2 weeks.
• State contractor license — Required in most states. Texas TACL: $75–$300. California C-20: $300–$500. Florida CAC: $100–$500. Check NASCLA.org for your state's requirements.
• NATE Certification — Not required but highly valued. Increases average ticket size 15–25%. Core exam: $175. Specialty exams (AC, heat pumps, gas heating): $105 each.
• General liability insurance — Minimum $1M per occurrence, $2M aggregate. Expect $1,500–$3,500/year for a solo operator. Required by most commercial property managers.
• Workers' comp (if hiring) — Required in most states once you have employees. Get this in place before hiring your first tech.
• Business registration — LLC protects personal assets. File with your Secretary of State ($50–$500). Get EIN from IRS.gov (free). Open a dedicated business checking account.

Equip Your Service Van and Stock Your Truck

Your van is your mobile office and warehouse. Equipping it right from day one prevents lost calls, delayed jobs, and wasted trips to the supply house.

• Service van — A used cargo van (Ford Transit, Chevy Express, Ram ProMaster) with 80,000–150,000 miles runs $15,000–$25,000. Wrap it with your brand for $1,200–$2,500 — becomes your best marketing.
• Refrigerant recovery machine — Required to legally remove refrigerants. Robinair CoolTech 34788NI or Yellow Jacket 95760 are industry standards. $400–$800 used, $1,200–$2,500 new.
• Digital manifold gauge set — Fieldpiece SM380V or Yellow Jacket 49967. $200–$600. Non-negotiable.
• Multimeter — Fluke 117 is the industry standard. $185. Required for electrical diagnosis on every job.
• Vacuum pump — JB Industries DV-200 or Robinair 15500. $180–$350. Required for proper system evacuation before every recharge.
• Truck stock (parts inventory) — Capacitors ($5–$30), contactors ($8–$25), filters (various), refrigerant ($20–$80/lb), thermostats ($25–$150), ignitors ($15–$60). Start with $1,500–$3,000 in stock.
• Tablet or ruggedized phone — For dispatch, invoicing, and photo documentation. Jobber, Housecall Pro, or Bizzby integrate scheduling and invoicing.

Build Your Service Menu and Pricing

HVAC pricing varies by region, but margin discipline is universal. Know your costs and price accordingly — or you'll stay busy and broke.

• Diagnostic / service call fee — $75–$150 is standard. Always charge this — it filters time-wasters and covers drive time.
• AC tune-up (seasonal maintenance) — $79–$149 per unit. Highest-volume service. Run specials in March–April and September–October.
• Refrigerant recharge (per pound) — R-410A: $50–$150/lb installed. R-22: $100–$200/lb (phased out, expensive). Never "just top off" — always diagnose the leak.
• Residential repair pricing — Capacitor replacement: $150–$250. Contactor: $200–$300. Blower motor: $400–$750. Compressor: $800–$2,500 (often not worth replacing on old units).
• Full system replacement — 2-ton split system: $3,500–$6,000 installed. 4-ton: $5,500–$9,000. Premium brands (Carrier, Trane) carry higher margins.
• Annual maintenance plan — $150–$350/year per system (bi-annual visits). Membership clients have 65% higher lifetime value and call you first for repairs.
• Commercial service — RTU (rooftop unit) maintenance: $250–$500/unit. Commercial work requires additional certifications but earns 30–50% higher rates.

Land Your First Maintenance Contracts

A roster of maintenance plan clients is the foundation of a predictable HVAC business. These clients call you first, pay faster, and refer more.

• Start with your network — Tell everyone you know you're launching. Homeowners with HVAC systems 8+ years old are your prime prospects — they're already dreading the replacement.
• Google Business Profile — Complete setup with service areas, photos of your van and work, and 10+ reviews before running any ads.
• Google Local Services Ads — "Google Guaranteed" badge for HVAC runs $20–$80 per lead. Highest-intent leads available. Start here before any other paid advertising.
• Partner with real estate agents — New homeowners need HVAC inspections and often equipment upgrades. One agent relationship can send 20–40 clients per year.
• Target property management companies — One PM account can mean 50–200 units of regular maintenance. Call local PMs, offer a competitive per-unit rate and guaranteed 24-hour response.
• Offer a new system maintenance plan — When you install a new system, automatically enroll the client in a 1-year maintenance plan. Converts 70%+ of new install customers.

Scale with Commercial Accounts and a Service Team

Solo HVAC technicians hit a ceiling around $80K–$100K. Breaking through requires commercial accounts and additional technicians.

• Hire your first tech strategically — Start with an apprentice or helper ($18–$22/hr). Train your standards. Document your process before hiring.
• Target commercial property managers — Office buildings, retail centers, restaurants, and apartment complexes need consistent preventive maintenance. One commercial account can be $30K–$100K/year.
• Add sheet metal and ductwork — New construction and renovation ductwork is high-margin work. Subcontract until you have the equipment and staff, then bring in-house.
• IAQ (Indoor Air Quality) services — UV light installations ($300–$800), whole-home air purifiers ($500–$1,500), humidifiers ($400–$1,200). High-margin add-ons with zero additional truck rolls.
• Fleet management — Second van means double the service capacity. Prioritize route efficiency — a tech doing 6 jobs/day beats a tech doing 3 jobs on opposite sides of town.

The most successful HVAC companies make more money on maintenance plans and add-ons than on emergency repairs. Build recurring revenue from day one.
