How to Start an HVAC Business in Nevada (2026)

Last updated: February 25, 2026

Starting an HVAC business in Nevada requires a C-21 Refrigeration and Air Conditioning Contractor license from the Nevada State Contractors Board (NSCB). Nevada’s desert climate – with summers regularly reaching 115°F in Las Vegas – creates massive, year-round demand for air conditioning services. The C-21 license requires 4 years of qualifying experience, passing two exams (Business & Law + C-21 trade), posting a bond determined by the NSCB, and paying application and biennial license fees totaling approximately $900+.

Nevada is a strong market for HVAC contractors: no state income tax on profits, high demand from both residential and commercial customers, and a construction boom across the Las Vegas and Reno metro areas. This guide covers all requirements from official NSCB sources.

How to Start an HVAC Business in Nevada (Step by Step)

Step 1: Meet the 4-Year Experience Requirement

Before applying for a C-21 license, you must document 4 years of qualifying experience within the past 15 years in refrigeration and air conditioning work. Qualifying experience includes:

Journeyman-level work in HVAC/refrigeration
Foreman or supervisor experience in HVAC
Prior HVAC contractor work
Education credit: Up to 3 of the 4 required years may be satisfied by accredited college or university coursework in a relevant field (engineering, construction management, etc.)

You must provide documentation of your experience: employer verification letters, pay stubs, W-2s, or other records. The NSCB reviews all experience claims. You can apply as either the Qualifier (the licensed individual whose credentials the license is based on) or as a business entity with a Qualifier on staff.

Step 2: Pass the Business & Law and C-21 Trade Exams

All C-21 applicants must pass two exams administered by PSI Testing Services:

Exam	Topics	Fee
Business & Law (B&L)	Nevada contractor law, business practices, safety codes, lien law, employment law	$140 combined (B&L + one trade exam)
C-21 Trade Exam	Refrigeration systems, AC principles, load calculations, controls, codes, troubleshooting	$140 combined (B&L + one trade exam)
Additional trade exams	Each additional classification	$95 each

PSI locations: Las Vegas, Reno, Elko (also available at PSI centers nationally)
Passing score: Typically 70% or higher for both exams
Exam results are valid for a limited period – apply to NSCB promptly after passing

Step 3: Submit Your NSCB Application

Submit your application to the Nevada State Contractors Board:

Las Vegas office: (702) 486-1100
Reno office: (775) 688-1141

Application package includes:

Completed application form
Application fee: $300
Financial statement (requirements vary by monetary limit):
- Under $25,000 limit: Self-prepared or CPA-compiled financial statement
- $25,000-$500,000 limit: CPA-compiled statement required
- Over $500,000: Reviewed or audited statement required
Proof of exam passage (exam scores)
Documentation of qualifying experience
Workers’ comp certificate (if you have employees)

After reviewing your application, NSCB will determine your monetary limit (the maximum value of a single contract you are authorized to bid) and your required bond amount.

Step 4: Post Your Contractor Bond

NSCB sets each contractor’s bond amount individually based on:

Monetary limit requested
Financial history and stability
Work experience and qualifications

Bond amounts typically range from $1,000 to $500,000. Most small HVAC contractors with standard monetary limits fall in the $1,000-$50,000 range. Obtain your bond from a surety company licensed to operate in Nevada. Annual premium is typically 1%-3% of the bond amount depending on credit score.

Step 5: Pay the Biennial License Fee

Upon NSCB approval, pay the $600 biennial license fee. Your C-21 license is valid for 2 years and must be renewed at the same $600 rate every 2 years. Continuing education requirements may apply at renewal – check with NSCB for current CE requirements.

Total initial licensing cost: approximately $900-$1,040+ ($300 application + $140 exams + $600 biennial fee, plus bond premium).

Step 6: Get EPA Section 608 Certification

Federal law mandates EPA Section 608 certification for technicians who handle refrigerants. All technicians working on HVAC systems with refrigerants must be certified – this applies regardless of your state license.

Type	Covers
Type I (Small Appliances)	Systems with less than 5 lbs of refrigerant
Type II (High-Pressure)	High-pressure refrigerants (most residential/commercial AC)
Type III (Low-Pressure)	Large chillers, low-pressure systems
Universal (Recommended)	All types – covers all refrigerant work

Cost: $150-$250
Providers: ESCO Institute, HVAC Excellence, Refrigeration Service Engineers Society (RSES)
Duration: Does not expire (one-time certification)

Step 7: Form Your LLC and Get Insurance

Required/recommended insurance for Nevada HVAC contractors:

Workers’ comp: Mandatory at 1 employee. Purchase from a private carrier – Nevada has no state fund. ($800-$2,500/year per employee depending on role)
General liability: $1 million per occurrence / $2 million aggregate. Most commercial clients and property managers require this before signing. ($3,000-$6,000/year)
Commercial auto: Required for service vehicles ($2,000-$4,000/year per vehicle)
Tools & equipment: Inland marine coverage for equipment and tools ($400-$1,000/year)
