Licensing requirements
While you don’t have to get your license right away to start working in HVAC in California, the state does require you to obtain a state-issued HVAC license or work under another licensed contractor if you want to legally perform work on air conditioning, heating, or refrigeration systems valued at more than $500 (including labor and materials).
HVAC licenses are issued by the California Contractors State License Board (CSLB) and are classified under Warm-Air Heating, Ventilating, and Air Conditioning Contractor (C-20). A C-20 contractor license will allow you to fabricate, install, service, repair, and maintain the following:
- Air conditioning systems
- Ventilating systems
- Warm-air heating systems
- Water heating pumps
- Ducts, flues, registers, humidity, and thermostatic control and air filters for any of these systems
HVAC contractors in California may also choose to get the C-4 license (hot water heaters, boilers, and steam fitting), C-38 license (refrigeration), and C-46 license (solar contractor).
Licenses must be renewed every two years and involve a license renewal fee of $450. Late renewals incur an additional fee of $225.
The CSLB offers free workshops on the first Friday of each month explaining how to get your contractor’s license.

- High demand – HVAC systems are essential for residential, industrial, and commercial properties. Skilled technicians are needed to install, repair, and maintain these systems.

How long in take to become a licensed HVAC technician in California?
That depends on the educational program and on-the-job training you choose, but it takes at least 4-5 years.
Remember, you’ll need 4 years of experience, from working on the job or as an apprentice, or at an accredited trade school or college program. At least one of these four years must be completed in a workplace setting.
A qualified individual who has at least 4 years of experience and has passed the HVAC license exam requirements will need to verify your experience doing jobs valued at $500 or less.
You’ll need to pass the two required exams – the trade exam, and the law and business exam. First-time applicants must also pass an open-book exam on asbestos.
You’ll complete a state background check including fingerprinting. You’ll have to get workers’ compensation insurance and submit proof of coverage and a contractor’s bond.
Can I transfer my HVAC license from another state to California?
Arizona, Louisiana, and Nevada have contractor license reciprocity agreements with California.
If you have an HVAC license from one of these states, you’ll still have to take the law and business exam, but you may be exempt from the trade exam. Check the Reciprocal Classifications List for more information.
Does California issue penalties for doing HVAC work without a license?
Yes. Contractors who work on HVAC projects worth over $500 without a license face penalties, including a $5,000 fee, misdemeanor charges, up to 6 months of jail time, and administrative fees that range from $200 – $15,000.
Repeated violations can lead to a mandatory 90-day jail sentence and a fine of $5,000 or 20% of the contract price.
