Before you can legally install, maintain, or repair refrigeration and air conditioning systems in Nevada, you will need a C-21 contractor license from the Nevada State Contractors Board. This license is required to perform HVAC work for others in Nevada — the general small-job exemption under NRS 624.031 explicitly does not apply to refrigeration, heating, or air-conditioning contractors, so a license is required regardless of project size. This guide details the complete process, from meeting the experience requirements to passing your exams and maintaining your license.
Do You Need a Contractor License to Perform HVAC Work in Nevada?
Yes, a contractor license is required to legally perform refrigeration and air conditioning (HVAC) work for others in Nevada, specifically the C-21 classification. The state defines a contractor as anyone who constructs, alters, repairs, or improves any building, which includes the installation and service of HVAC systems. The Nevada State Contractors Board (NSCB) issues the C-21 Refrigeration and Air Conditioning license for this scope of work.
The C-21 license covers the installation, maintenance, and repair of all types of refrigeration and air conditioning systems, including those that use solar energy. Operating without the proper license can lead to significant penalties, including fines and potential criminal charges.
Nevada C-21 Refrigeration and Air Conditioning License Requirements
To qualify for a Nevada C-21 license, an applicant must demonstrate sufficient experience, prove financial responsibility, and pass state-approved examinations. The specific requirements are broken down into three main categories: experience, financial, and examination.
Experience Requirements
You must document at least four years of journeyman-level experience in the C-21 trade within the last 15 years.
- A journeyman is defined as an individual who is a skilled mechanic and is qualified to perform the trade without supervision.
- Experience is verified through a detailed work experience form and certifications from qualified individuals (such as a licensed contractor, employer, or union representative) who can attest to your skills and work history.
- Acceptable documentation may include detailed project lists, employment records, or other evidence that substantiates your hands-on experience in the field.
Financial Requirements
Applicants must demonstrate financial responsibility to the satisfaction of the Board.
- You will need to submit a financial statement and a bank verification form. The Board will also review your credit report.
- A surety bond is required. The NSCB determines the bond amount based on your license type, monetary limit, financial history, experience, and character; it may range from $1,000 to $500,000. If you post a cash bond in lieu of a surety bond, a $200 biennial administrative fee applies.
- If you plan to hire employees, you must provide proof of Workers' Compensation insurance coverage.
- While not a state licensing requirement, maintaining General Liability insurance is a standard business practice strongly recommended for all contractors.
Exam Requirements
All applicants must pass two separate exams administered by the state's testing vendor.
- C-21 Refrigeration and Air Conditioning Trade Exam: This exam tests your technical knowledge of HVAC systems, installation, maintenance, and safety.
- Nevada Business and Law Exam: This exam covers critical business management and legal topics relevant to contracting in Nevada.
- Both examinations are administered by PSI Licensure.

Maintaining Your Nevada C-21 License: Renewals and Continuing Education
Maintaining your license in good standing requires timely renewal and adherence to Board regulations.
Renewal Cycle
The Nevada C-21 contractor license must be renewed every two years (biennially). The NSCB will send a renewal notice to your address on file before the expiration date. It is your responsibility to renew on time, whether or not you receive the notice.
Continuing Education
Confirm whether continuing education is required for C-21 license renewal directly with the Nevada State Contractors Board before each renewal period.
Maintaining Bond and Insurance
You must maintain a valid surety bond and proof of workers' compensation insurance (if applicable) for the entire duration of your license period. A lapse in coverage can result in the suspension or revocation of your license.
Nevada Contractor License: Licensure by Endorsement
Nevada does not have automatic, blanket reciprocity for the C-21 license. However, the Nevada State Contractors Board offers a licensure by endorsement program that can waive the state-specific trade exam and/or experience certification process for qualified applicants.
- Trade Exam Equivalency for C-21: Arizona, Louisiana, and Tennessee are listed on the NSCB's endorsement chart as having substantially equivalent C-21 trade examinations. Applicants holding a current, active C-21 license from one of these states may qualify to have the Nevada trade exam requirement waived.
- Florida (C-21/CM Mechanical Contractor): Florida is listed on the NSCB endorsement chart for C-21, but applicants are still required to pass the Nevada trade exam.
- Nevada Business and Law Exam Always Required: All endorsement applicants must still pass the Nevada-specific Business and Law exam regardless of home state.
- Other Requirements Remain: All other licensing documents, financial statements, background checks, bond, and insurance requirements still apply even under endorsement.
