Businesses must register with the California Secretary of State for entity formation, obtain a seller's permit from the California Department of Tax and Fee Administration if selling taxable goods, and register with the EDD for payroll taxes if employing workers. San Francisco, Los Angeles, and other major cities have their own business registration and tax requirements.

Common Mistakes to Avoid

1
Working without EPA 608 certification — it is federally illegal to purchase refrigerants without certification
2
Not building a service agreement portfolio — maintenance agreements provide $150-$300/system in annual recurring revenue
3
Undercharging for after-hours emergency calls — summer AC failures are emergency situations justifying $150-$250/hour
4
Not diversifying into commercial HVAC — commercial jobs are larger, less seasonal, and often more profitable
5
Skipping proper refrigerant recovery — illegal venting of refrigerants results in EPA fines up to $44,539/day

Next Steps to Launch Your HVAC Business

1
Form your LLC in California — HVAC contractors face significant liability for refrigerant handling and equipment installations (filing fee: $70)
2
Obtain EPA Section 608 Universal certification — required by federal law to purchase and handle refrigerants (R-22, R-410A, R-32); take the exam through ESCO Group
3
Obtain your California HVAC contractor license — most states require a specialty contractor license with exam, experience, and financial documentation
4
Get a contractor surety bond ($10,000–$25,000) and HVAC contractor liability insurance ($1,500–$5,000/year)
5
Complete OSHA 10-hour construction safety training — required by commercial property managers and most new construction GCs
6
Open trade accounts with Ferguson HVAC, Johnstone Supply, or California regional HVAC distributors for equipment and parts
7
Register for NATE (North American Technician Excellence) certification — differentiates your technicians and is required by some manufacturer warranties
8
Set up service agreement software (ServiceTitan or Housecall Pro) to offer maintenance plan memberships generating recurring annual revenue

Frequently Asked Questions

Starting an HVAC business costs $20,000 to $200,000. A solo HVAC technician with a used van and basic equipment can launch for $20,000-$40,000. A 2-3 technician company with equipped vans, a parts inventory, and a service agreement program typically costs $70,000-$150,000. Larger commercial HVAC contractors can exceed $200,000.

Required: EPA Section 608 certification (universal level covers all refrigerants, $20-$50 exam fee). Recommended: North American Technician Excellence (NATE) certification for credibility. State contractor licenses vary — most states require a licensed HVAC contractor to pull permits and employ technicians.

HVAC service call rates: $75-$150 minimum service call fee, $75-$150/hour for repair labor. Equipment installation: furnace $800-$2,500, AC unit $3,000-$7,000, heat pump $4,000-$10,000 (equipment + labor). Maintenance agreements: $150-$300/system/year. Emergency after-hours calls: 1.5-2x standard rates.

HVAC is highly seasonal — AC work peaks May-September and heating work peaks November-February in most of the US. The shoulder seasons (spring tune-ups, fall start-up) are driven by maintenance agreements. Companies with strong maintenance agreement portfolios have more consistent year-round revenue. Sun Belt markets (Arizona, Florida, Texas) have year-round AC demand.

Top channels: (1) Google search ads for 'AC repair near me' and 'furnace repair' are the highest-converting source, (2) annual maintenance agreement campaigns, (3) Angi and HomeAdvisor for residential, (4) property management companies for multi-unit commercial work, and (5) referrals from satisfied customers (the best long-term source).
