Use the map with care.

  • Selected Core, Type I, Type II and Type III written-knowledge foundations; not complete official examination coverage.
  • 200 learning items across48 rule/task families; several related cases share a source rule. Counts do not represent200 independent technical concepts.
  • Independent qualified HVAC educator review, field competence and learner calibration remain pending.
  • Current appliance-specific instructions and applicable regulations control actual work. This is an untimed learning tool, not an EPA-approved certification examination.
  • Pressure-table learning and simplified loss calculations do not replace every regulatory calculation method or an actual recovery procedure.
