- The under $1,000 handyman exemption does not cover refrigeration, heating or air conditioning work, so HVAC work at any size needs a license.
- At least 4 years as a journeyman, foreman, supervising employee or contractor in the classification, within the last 15 years. Up to 3 years can come from accredited college or equivalent training. Transferable military training or a master certification from a government agency can also count.
- Plan for a trade exam and a business and law exam.
- A license bond set by the board at approval, from $1,000 to $500,000, based on license type, monetary limit, finances, experience and character.
- Every two years, with the $600 license fee.

| C-21b Air-Conditioning | Install, repair and service heating and cooling equipment and ductwork that use evaporation, refrigeration, boilers or combustion |
| C-21c Sheet Metal | Fabrication and installation of sheet metal, including ducts |
| C-21d Maintenance | Repairing and replacing parts of existing air conditioning and refrigeration systems, without altering the system design |
| C-21 (full) | All C-21 subclassifications |

Separate from any state license, the EPA requires Section 608 certification for anyone who works on equipment with refrigerant. It is federal and applies in every state.
What it costs in Nevada
The board lists 6 fees along the way. These are the state's own numbers. Insurance, any bond, exam prep and your business registration come on top.
| Fee | Amount |
|---|---|
| Application fee | $300 |
| License fee, every two years | $600 |
| Late renewal fee, active license | $150 |
| Residential Recovery Fund assessment for residential work, monetary limit up to $1,000,000 | $200 |
| Residential Recovery Fund assessment for residential work, monetary limit over $1,000,000 but limited | $500 |
| Residential Recovery Fund assessment for residential work, unlimited license | $1,000 |
Insurance and bond
Insurance. Proof of workers comp coverage is required to get, keep and renew a license, unless you are exempt and sign an exemption affidavit.
Bond. A license bond set by the board at approval, from $1,000 to $500,000, based on license type, monetary limit, finances, experience and character.
Renewal and licenses from other states
Renewal. Every two years, with the $600 license fee.
Reciprocity. Licensure by endorsement: if you held an active license in a qualifying state for the past 4 years with the same qualified individual and no discipline, the board can waive the trade exam and the experience check. You still take the Nevada Business and Law exam.
Good to know in Nevada
- C-21 work is not treated as incidental to other specialty work, so other specialty contractors cannot do it.
- EPA Section 608 certification is a federal requirement for anyone who handles refrigerant.
- Applicants must submit a financial statement and a background disclosure with fingerprint authorization.
After you are licensed
The license lets you take the work. Getting the work is the next job.
- Register the business. If you work under a name other than your own, register it where your state asks (often the Secretary of State, sometimes the county), and keep the name the same on your license, your truck and your invoices.
- Claim your Google Business Profile. It is the listing people see when they search for HVAC repair near them. Fill in your service area, hours and real photos of your work.
- Put up a website that shows the license. Customers look for it before they call. Koira builds a contractor website for you and keeps it current.
- See where you stand. The free Koira report checks how your business shows up in search and on maps against shops near you.
