What You'll Learn

Key competencies developed through this program

Auto-populated·from NSX Competency Framework

Mastery: developing (Level 2)(based on Certification)

  • Multimeters, clamp meters, and continuity testers — operate independently to diagnose electrical faults in HVAC control boards and wiring on light-commercial job sites.
  • OSHA safety codes and EPA refrigerant handling regulations — apply routinely and without prompting to maintain compliance across residential and small-commercial service assignments.
  • Design specifications and equipment manuals — read and apply with limited oversight to configure heating and cooling components correctly during installation projects.
  • Heating and cooling system malfunctions — discuss directly with building occupants using active listening skills to narrow the scope of diagnosis before beginning repairs.
  • Refrigerant lines, gas piping, and condensate drains — connect and pressure-test with standard tools to form complete, leak-free systems on replacement equipment jobs.
  • Thermostat and control panel settings — adjust systematically after installation to balance airflow and temperature distribution across residential duct systems.
  • Preventive maintenance schedules — execute independently, including coil cleaning, lubrication, and filter changes, to sustain equipment efficiency on assigned accounts.
  • Installed HVAC systems — inspect and functionally test against plan specifications to verify code compliance and detect operational deficiencies before customer sign-off.
  • Service records and maintenance logs — document accurately using facilities management or CRM software to support scheduling and warranty tracking for a recurring client base.
  • Common mechanical and refrigeration faults — diagnose using deductive reasoning and manufacturer troubleshooting guides to complete routine repairs with minimal supervision.
