HVAC Excellence AC study plan

HVAC Excellence AC · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Employment Ready

  • Map every Employment Ready objective (safety, tools, refrigerant handling, electrical fundamentals, customer relations) into a personal checklist with a confidence rating 1-5 per item

  • Demonstrate safe refrigerant cylinder handling and recovery setup by writing a step-by-step procedure from memory and checking it against EPA Section 608 rules

  • Explain the refrigeration cycle (compression, condensation, metering, evaporation) aloud in under three minutes without notes

  • Solve ten basic electrical problems using Ohm's Law and power formulas, showing work

Your checkpoint

Completed Employment Ready objective checklist with confidence ratings plus a one-page refrigeration cycle diagram drawn from memory

Week 2

Employment Ready & Specialty Certifications

  • Diagnose five simulated no-cooling scenarios by listing the sequence of checks (airflow, charge, superheat/subcooling, electrical) before touching a gauge

  • Practice brazing and nitrogen purge procedures on paper: sequence the steps and identify the two most common contamination mistakes

  • Identify the entry requirements and scope differences among the specialty certifications (residential A/C, light commercial, heat pump, gas heat)

  • Calculate superheat and subcooling for eight given pressure/temperature data sets

Your checkpoint

Diagnostic worksheet with five written troubleshooting sequences and eight completed superheat/subcooling calculations

Week 3

Specialty Certifications

  • Build a comparison table of Specialty certification exam scopes, prerequisites, and typical field tasks for each specialty track

  • Explain heat pump defrost cycles, reversing valve operation, and auxiliary heat staging in writing

  • Outline combustion analysis steps for gas heating: draft, CO, manifold pressure, and heat exchanger inspection

  • List the five most common code and safety violations tested in specialty exams and the correct practice for each

Your checkpoint

One-page specialty certification comparison matrix plus a written heat pump and gas heat troubleshooting summary

Week 4

Specialty Certifications & Professional Level Certifications

  • Complete a timed 40-question self-made practice set drawn from your own notes across Domains 1-2 and score it honestly

  • Review every missed item and write the correct reasoning in your own words

  • Summarize the difference in depth and scope between Specialty and Professional Level certifications

  • Draft a list of Professional Level topics you have not yet studied and rank them by risk

Your checkpoint

Scored practice set with a written error log and a ranked list of remaining Professional Level knowledge gaps

Week 5

Professional Level Certifications

  • Work through commercial refrigeration and light commercial system topics: walk-in coolers, parallel racks, and defrost controls

  • Explain psychrometrics: dry bulb, wet bulb, dew point, and how to plot a basic process on a psychrometric chart

  • Describe load calculation inputs for a residential retrofit and identify which inputs most affect sizing

  • Practice interpreting wiring diagrams and ladder schematics by tracing three circuits

Your checkpoint

Three traced wiring diagrams with labeled components and a one-page psychrometric summary with two worked chart examples

Week 6

Professional Level Certifications & Master Specialist Certifications

  • Distinguish Master Specialist scope from Professional Level: advanced controls, commissioning, and system design review

  • Explain VRF/VRV and variable-speed compressor control strategies in writing

  • Outline commissioning documentation: start-up sheets, airflow verification, charge verification, and customer handoff

  • Identify building automation and economizer control sequences commonly tested at the master level

Your checkpoint

Commissioning checklist template covering airflow, charge, controls, and handoff documentation

Week 7

Master Specialist Certifications & Educator Credentialing Exams

  • Summarize the Educator Credentialing exam scope: instructional methods, lab safety oversight, assessment design, and program accreditation awareness

  • Draft a 20-minute lesson outline teaching superheat measurement to an entry-level student, including a lab safety brief

  • Compare Master Specialist and Educator pathways and list the evidence each requires

  • Explain how to write performance-based assessments with measurable pass criteria

Your checkpoint

Complete 20-minute lesson plan with safety brief and a rubric containing at least four measurable performance criteria

Week 8

Professional Level Certifications & Master Specialist Certifications & Educator Credentialing Exams

  • Run two full timed mock exams covering all five domains and record per-domain scores

  • Re-teach your three weakest objectives aloud as if instructing a student, then correct any gaps

  • Review the error log from Weeks 4 and 8 and confirm every prior miss is now explainable

  • Finalize a one-page formula and safety reference sheet you can recreate from memory

Your checkpoint

Two scored mock exams with per-domain breakdown and a finalized one-page reference sheet recreated from memory

Milestones

Week 2: Can explain the refrigeration cycle and Ohm's Law applications without notes and score at least 70% on a self-made 20-question Domain 1 set

Week 4: Score at least 75% on the 40-question Domains 1-2 practice set and have a written error log with no unexplained misses

Week 6: Can trace a wiring diagram and explain a commissioning sequence end to end; score at least 75% on a 30-question Domains 3-4 set

Week 8: Score at least 80% overall on both full mock exams with no domain below 70%, and recreate the reference sheet from memory
