HVAC System Performance Diagnostics

HVAC System Performance Diagnostics

This 3-4 hour virtual course teaches noninvasive HVAC diagnostic methods, so technicians can evaluate system performance without connecting to the refrigerant circuit.

Noninvasive HVAC diagnostics reduce system intrusion and improve accuracy

Noninvasive diagnostic practices are becoming standard across the HVAC industry because they reduce system intrusion while improving diagnostic accuracy and efficiency. This course gives technicians the skills to evaluate system performance without attaching refrigerant gauges to build a complete picture of how the system is operating.

What HVAC System Performance Diagnostics covers

This course teaches technicians to evaluate HVAC systems from a whole-system perspective using noninvasive methods. By the end of this course, technicians will learn to:

  • Measure and interpret static pressure to identify duct restrictions and airflow problems

  • Calculate airflow using temperature and equipment data without direct measurement tools

  • Apply psychrometric principles to understand how moisture and temperature affect system performance

  • Use enthalpy calculations to assess system capacity and verify equipment operation

  • Identify common HVAC performance issues through temperature evaluation and data interpretation

  • Diagnose both cooling and heating systems using a structured, non-invasive workflow

HVAC System Performance Diagnostics FAQ

Service technicians looking to expand beyond gauge-based HVAC troubleshooting, lead technicians and field supervisors responsible for quality assurance on service calls, technicians preparing for performance-based service work or home performance contracting, and any HVAC professional who wants to diagnose systems more accurately with less intrusion.

No. The diagnostic principles covered apply to both residential and light commercial systems. Static pressure, airflow, psychrometrics, and enthalpy work the same way regardless of building type.

No. This is a virtual instructor-led course. Technicians learn the theory and methods during the session and apply them in the field afterward.

Gauge-based diagnostics focus on refrigerant pressures and superheat/subcooling. This course teaches technicians to evaluate system performance using static pressure, airflow, temperature, and enthalpy calculations instead of connecting to the refrigerant circuit.

The training runs 3-4 hours in a single virtual session, and participants can complete it on their own time within 180 days of enrollment.

Yes. Participants receive an ACCA certificate of completion.
