NV HVAC Contractor study plan

Perform a complete manual-style heating and cooling load estimate for a 2,000 sq ft single-family house, documenting orientation, glazing, insulation, and internal gains

Calculate sensible and latent loads separately for three representative rooms and explain why the split matters for equipment selection

Select equipment capacity from your calculated loads and justify the margin you applied against oversizing

Sketch a trunk-and-branch duct layout for the same house and label supply, return, and transfer air paths

Size supply and return ducts using friction-rate and velocity methods, then compare the two results

Compute external static pressure for a full air-handler setup including filter, coil, heat strips, and grilles

Diagnose three air distribution faults (high static, short cycling, uneven room temperatures) and write the corrective action for each

Explain zoning, balancing dampers, and bypass strategy for a two-zone residential system

Trace the vapor-compression cycle on a pressure-enthalpy diagram and label superheat, subcooling, and compression ratio for a 410A system

Calculate superheat and subcooling from gauge and thermometer readings and state what each value indicates about charge and metering

Compare R-410A, R-32, R-454B, and R-22 on GWP, glide, and retrofit implications

Summarize the refrigerant management rules that apply to recovery, recycling, evacuation, and recordkeeping for technicians

Read a residential HVAC wiring diagram and identify line, control, and safety circuits for a condensing unit and air handler

Size branch circuit conductors, overcurrent protection, and disconnect for a given nameplate MCA and MOP

Wire and explain a basic heat pump control sequence including defrost, auxiliary heat, and emergency heat lockout

List the electrical code checks an inspector would make on an HVAC rough-in

Outline the Nevada contractor licensing process: classification, qualifying party, application, and examination requirements

Describe the disciplinary and complaint process and the consequences of unlicensed contracting in Nevada

Identify the contract terms Nevada requires or restricts, including change orders, payment, and notice provisions

Explain lien rights, prompt payment, and the notice-to-owner requirements that affect an HVAC contractor's cash flow

Write a startup and commissioning sequence for a new split system from rough-in through homeowner demonstration

Specify the tests to perform at each stage: pressure test, evacuation and decay test, airflow verification, and refrigerant charge check

Build a controls checkout list covering thermostat configuration, staging, safeties, and economizer or ventilation operation if present

Draft a commissioning report template with pass/fail criteria and sign-off lines

Estimate labor and material costs for a residential replacement job and build a bid with overhead and profit

Identify the safety hazards on an HVAC job site and state the control for each, including refrigerant, electrical, and fall hazards

Describe project scheduling and coordination steps for a retrofit that requires a permit and inspection

Explain how Nevada licensing rules affect subcontracting and hiring on a project

Take two full-length timed practice exams and log every missed question by domain

Re-study the two weakest domains using your own notes and worksheets from earlier weeks

Recite from memory the key formulas for load, airflow, superheat, subcooling, and conductor sizing

Review Nevada licensing rules and refrigerant regulations one final time
