NV HVAC Contractor study guide
NV HVAC Contractor · Work through your exam, one topic at a time.
The Nevada State Contractors Board (NSCB) determines the qualifications of contractor license applicants, and that process explicitly includes written examinations, background investigations, and financial responsibility assessments. The Board also sets licensing conditions such as field and scope limitations, bond requirements, and contractual limits, and it promulgates rules to implement and enforce NRS 624, the enabling statute. The NV HVAC Contractor study guide has 8 sections and about 2,375 words.
01Nevada contractor licensing law and Board regulations (NRS 624)
Domain 1 tests how NRS 624 and Nevada State Contractors Board regulations control who may bid, contract, and perform HVAC work, and how licenses are classified, qualified, and disciplined. A contractor license is required to bid, offer to contract, or perform construction work for compensation, including subcontractors.
344 words, about 2 min02HVAC systems and equipment
Domain 2 tests equipment families, capacity ratings, efficiency metrics, and selection logic for HVAC systems. DX split systems pair an outdoor condenser with an indoor coil and air handler.
312 words, about 2 min03Heating and cooling load calculation
Domain 3 tests heating and cooling load calculation: the inputs, the difference between load and equipment capacity, and the ACCA/ASHRAE workflow. A load calculation accounts for design outdoor and indoor conditions, envelope U-values and solar heat gain, orientation, infiltration, ventilation, internal gains from people and appliances, and duct gain or loss.
275 words, about 1 min04duct design, and air distribution
Domain 4 tests duct sizing and air distribution: available static pressure, friction rate, velocity, fittings, and room delivery. Use Manual D or an equivalent method.
304 words, about 2 min05Refrigeration cycle, refrigerants, and environmental regulations
Domain 5 tests the vapor-compression cycle, charging indicators, refrigerant safety, and federal environmental rules. The compressor raises refrigerant pressure and temperature.
295 words, about 1 min06Electrical and controls for HVAC equipment
Domain 6 tests electrical safety, branch-circuit selection, motors and components, and low-voltage controls. Use the equipment nameplate.
293 words, about 1 min07Installation, testing, and commissioning
Domain 7 tests installation quality, pressure testing, evacuation, charging, airflow verification, and commissioning documentation. Follow manufacturer instructions and local code.
286 words, about 1 min08Business, contracts, safety, and project management
Domain 8 tests business practices, Nevada contract and lien basics, jobsite safety, and project controls. Use a written contract with scope, price, payment schedule, schedule, license number, exclusions, warranty, and a change-order process.
