About Course

HVAC Fundamentals is a beginner-friendly online course that teaches you how heating, ventilation, air conditioning, and refrigeration systems work from the ground up. You’ll learn core safety practices, basic HVAC physics, reading schematics, essential tools and multimeter use, low-voltage controls, and the full refrigeration cycle—including pressure readings, superheat/subcooling, recovery, evacuation, and charging methods. The course also covers real-world equipment like gas furnaces, heat pumps, boilers/hydronics, mini-splits, and commercial rooftop basics, with a strong focus on troubleshooting mindset, callback prevention, professionalism, permits/code awareness, and EPA 608 + NATE prep. Each lesson includes practical knowledge checks and takeaways so you can build job-ready confidence for entry-level HVAC work.

What Will You Learn?

  • Safety-first habits and risk awareness come before every diagnosis or repair.
  • Airflow problems cause many “refrigerant-looking” symptoms—verify airflow early.
  • Use a repeatable process: prove power → prove path → prove load.
  • Read schematics confidently to trace circuits and isolate failures faster.
  • Master the refrigeration cycle fundamentals to understand pressures, temps, and performance.
  • Use gauge manifolds correctly and interpret pressure readings in real conditions.
  • Apply superheat and subcooling to confirm charge and system health (after basics are proven).
  • Recover, evacuate, and charge refrigerant legally and correctly (EPA 608 compliance).
  • Diagnose and service major equipment types: gas furnaces, heat pumps, boilers/hydronics, mini-splits, and basic commercial RTUs.
  • Prevent callbacks through commissioning, documentation, and professional customer communication.
