Nevada: HVAC contractor licensing, reciprocity and contract rules.

This page lists what Nevada publishes about licensing an HVAC or mechanical contractor and contracting with homeowners: who issues the licence, whether one is required statewide, the classes and qualifications, insurance or bond minimums, reciprocity with other states, renewal and continuing education, and the state's home-improvement contract statute if it has one.

It is built for owners of residential HVAC companies, especially those hiring across a state line or opening a second territory. Every entry is a snapshot of what the cited source published on the verification date; it is a research starting point, not legal advice.

Nevada, field by field.

Contractor licensing authority

Nevada State Contractors Board (NSCB), which licenses contractors under NRS Chapter 624 and NAC Chapter 624; HVAC work is Classification C-21, Refrigeration and Air-Conditioning (NAC 624.380). The Board publishes at nvcontractorsboard.com (its bulletins also give www.nscb.nv.gov).

HVAC licence required

Statewide, with no dollar threshold for HVAC-type work. NRS 624.031(6) exempts "Any work to repair or maintain property the value of which is less than $1,000, including labor and materials, unless:" one of five conditions applies, and condition (b) is "The work is of a type performed by a plumbing, electrical, refrigeration, heating or air-conditioning contractor;" — so the under-$1,000 exemption does not reach HVAC work. The other conditions are (a) "A building permit is required to perform the work;", (c) work of a type performed by a contractor in a Board-prescribed classification that "significantly affects the health, safety and welfare of members of the general public;", (d) work performed as part of a larger project valued at $500 or more or split into sub-$500 contracts to evade the chapter, and (e) work performed by a licensee or a licensee's employee. A C-21 Refrigeration and Air-Conditioning licence (NAC 624.380) is the specialty classification for HVAC work. NRS 624.700(4): a bid or contract made in violation of the licensing requirement in subsection 1 "shall be deemed void ab initio."

Licence classes & qualifications

Classification C-21 Refrigeration and air-conditioning: "The Board will grant to qualified applicants a license in the specialty of refrigeration and air-conditioning." (NAC 624.380(1)); subclassifications in NAC 624.380(3): C-21a refrigeration (devices holding air below 50°F in refrigerated spaces, with related insulation, ducts and controls), C-21b air-conditioning (installing, repairing, servicing and maintaining climate-control equipment and ductwork using evaporation, refrigeration, boilers or combustion), C-21c sheet metal, C-21d maintenance of existing systems (excluding full condenser replacement on remote systems and any change to system design), C-21e solar air-conditioning, C-21f chilled and hot water systems, C-21g industrial piping. The qualifying individual must have had, "within the 15 years immediately preceding the filing of the application for licensure", "at least 4 years of experience as a journeyman, foreman, supervising employee or contractor" in the classification, with accredited training creditable for "not more than 3 years" (NRS 624.260(6); NAC 624.590(4); Board License Requirements page: "at least four full years of experience as a journeyman, supervising employee or contractor"), and must pass the Business and Law (CMS) examination and the C-21 trade examination unless waived (NAC 624.600; the Board allows three attempts, after which "the application becomes void pursuant to NAC 624.600(3)."). A financial statement is required at every monetary-limit tier — CPA-compiled, reviewed or audited statements above $25,000 — plus a bank verification form (Board License Requirements page, citing NRS 624.260, 624.262, 624.263 and 624.265).

Insurance / bond minimum

Surety bond or cash deposit set by the Board at licence approval: the amount "must be not less than $1,000 or more than $500,000." (NRS 624.270(4)); the Board's Bonds page states "The bond can vary in amount from $1,000 to $500,000." based on licence type, monetary limit, financial responsibility, experience and character, that a cash deposit (cashier's check for the full amount) may be posted in lieu of a surety bond subject to "A biennial administrative fee of $200.00", and that the deposit is held for two years after the licence ends or the bond requirement is relieved. General-liability insurance minimum: none stated in NRS Chapter 624 as read or on the Board's License Requirements and Bonds pages.

Reciprocity

Licensure by endorsement (the Board's term) with states the Board has determined have requirements "substantially equivalent to the requirements in this State for licensing contractors." (NAC 624.615(1)(a)): Alabama, Arizona, California, Connecticut, Florida, Hawaii, Louisiana, New Mexico, North Carolina, South Carolina, Tennessee, West Virginia. The applicant must "Hold an active license in the endorsing state, with the same qualified individual, for the past four (4) Years." with no discipline imposed or pending; endorsement waives the state-specific trade examination (where the endorsing state has an equivalent exam) and the experience-certification requirement — NAC 624.590(3)(a) waives experience certification for an applicant with at least 4 years of Board-approved experience as a contractor licensed in good standing in an endorsing state, and NAC 624.600(2) waives the examination for an applicant who passed an approved endorsing-state exam or a NASCLA-accredited exam — and the Nevada Business and Law examination is still required (Board Licensure by Endorsement page).

Renewal & continuing education

"each license issued under the provisions of this chapter expires 2 years after the date on which it is issued." (NRS 624.283(1), version effective through December 31, 2029; the version effective January 1, 2030 keeps the two-year term and lets the Board prescribe shorter or longer periods by regulation). No continuing-education requirement appears in NRS Chapter 624 or NAC Chapter 624 as read in full, or on the Board's License Renewals page, which gives online-portal instructions only.

Home-improvement contract rule

NRS 624.970 (added to NRS by 2023, 1047 — A.B. 39): "On and after October 1, 2023, any contract entered into between a residential contractor and the owner of a single-family residence who occupies the single-family residence for work concerning a residential improvement must comply with the provisions of this section and all applicable regulations adopted by the Board." Subsection 2 requires the contract to contain: contractor name, address, licence number and monetary limit; owner name and mailing address; property address or legal description; date executed; estimated completion date; description of the work; "The total amount to be paid to the residential contractor by the owner." including taxes; "The amount, not to exceed $1,000 or 10 percent of the aggregate contract price, whichever is less, of any initial down payment or deposit paid or promised to be paid to the residential contractor by the owner before the start of the work." (NRS 624.970(2)(g) — this paragraph does not apply if the contractor "has filed with the Board a bond solely for the protection of consumers in the amount of $100,000" or "has been granted relief by the Board pursuant to subsection 5 of NRS 624.270", and it is voidable by the owner under subsection 1(b); the Board's September 8, 2023 bulletin: the amount taken up front "can't exceed $1,000 or 10% of the aggregate contract price, whichever is less"); a statement that the NRS 624.520 and 624.600 notices were given; a change-order clause — "A change order is not enforceable against the owner who is contracting for work concerning a residential improvement" unless it sets out all changes in scope and price and the owner accepts it (NRS 624.970(2)(i)); a plan and scale drawing for new work (repairs exempt); a progress-payment schedule in dollars and cents capped at the value of work performed unless a payment and performance bond is furnished; and pro rata payment of any salesperson commission (NRS 624.970(2)(j)–(l)). A non-compliant contract may be modified by the owner to comply (subsection 1(a)). "All written information provided in the contract must be printed in at least 10-point bold type." and the contractor must give "a legible copy of all documents signed and a written and signed receipt for any money paid", deliverable electronically (NRS 624.970(4)); a term that requires a person "to waive any right provided by this chapter" or relieves a person of an obligation under the chapter is void (NRS 624.970(5)); "The residential contractor shall apply for and obtain all necessary permits." (NRS 624.970(6)). NRS 624.970 as read contains no cancellation-period provision. The Board's Residential Improvements page states "by law a contract with an unlicensed contractor is null and void."
