HVACR Core Knowledge and Skills
Define the refrigeration cycle state points (evaporator, compressor, condenser, metering device) and label them on a hand-drawn pressure-enthalpy sketch without notes.
Convert between saturated temperatures, pressures, and superheat/subcooling values for at least three common refrigerants using a printed PT chart.
Explain the function of each major system component (compressor, condenser, evaporator, metering device, accessories) in two to three sentences each, in your own words.
Identify the four refrigerant states and describe what changes at each transition in a basic system.
Your checkpoint
A one-page annotated system diagram with all state points, component functions, and a worked superheat/subcooling calculation for one refrigerant.
HVACR Core Knowledge and Skills
Describe airflow fundamentals: static pressure, total external static pressure, and how to measure them with a manometer.
Calculate sensible and latent heat loads using the airflow, temperature-difference, and psychrometric relationships.
Read a psychrometric chart to find dew point, wet-bulb, and enthalpy for three sample conditions.
Outline duct sizing and pressure-drop basics for supply and return systems.
Your checkpoint
A worksheet of five solved airflow and psychrometric problems showing each formula, substitution, and final answer with units.
System Performance and Efficiency
Compute system capacity and efficiency metrics (EER, SEER2, HSPF2, COP) from given input values and explain what each measures.
Perform a charging procedure decision: determine when to use superheat vs. subcooling based on metering device type and system configuration.
Diagnose three common performance faults (undercharge, overcharge, restricted airflow) from a set of gauge and temperature readings.
Explain how airflow, refrigerant charge, and duct leakage interact to affect delivered efficiency.
Your checkpoint
A troubleshooting table matching six symptom sets to likely causes, with the corrective action and the measurement that confirms the diagnosis.
System Performance and Efficiency & Refrigerant Safety and Environmental Compliance
Interpret manufacturer performance data (expanded ratings) to compare two equipment selections at design conditions.
Identify refrigerant safety classifications (A1, A2L, A3, B1) and state the handling implications of each.
Describe safe refrigerant recovery, recycling, and reclamation procedures and the equipment used for each.
Explain the environmental rules that govern refrigerant venting, leakage, and recordkeeping in general terms.
Your checkpoint
A two-page comparison memo selecting between two systems using capacity and efficiency data, plus a refrigerant safety-class quick-reference card.
Refrigerant Safety and Environmental Compliance
Apply cylinder safety practices: hydrostatic test dates, filling limits, valve protection, and transport and storage rules.
Describe PPE and oxygen-deficiency hazards for common refrigerants, including detection and ventilation responses.
Outline evacuation and dehydration procedures, including micron-level targets and the role of nitrogen and triple evacuation.
Explain refrigerant leak detection methods and how to respond to a detected leak safely.
Your checkpoint
A written procedure checklist for a compliant recovery-and-evacuation job, from setup through final leak check and documentation.
Electrical, Controls, and Troubleshooting
Read and interpret HVAC wiring diagrams, including ladder diagrams and component symbols, to trace a complete circuit.
Measure voltage, current, resistance, capacitance, and continuity with a multimeter and interpret each reading against expected values.
Explain the operation of contactors, relays, capacitors, transformers, and motors in a residential/commercial system.
Describe lockout/tagout and electrical safety practices before working on energized equipment.
Your checkpoint
A completed circuit-tracing exercise: given a schematic, list expected voltages at five test points and the fault each abnormal reading would indicate.
Electrical, Controls, and Troubleshooting & HVACR Core Knowledge and Skills
Diagnose control-system faults: thermostat wiring, defrost controls, pressure switches, and safeties.
Apply a structured troubleshooting sequence to three simulated faults, documenting measurements at each step.
Verify compressor and fan motor electrical integrity using winding resistance and insulation checks.
Integrate mechanical and electrical findings into a single repair recommendation for each simulated fault.
Your checkpoint
Three written diagnostic reports, each with symptom, measurements, root cause, repair, and verification test.
