HVAC and refrigeration technicians are increasingly expected to bring digital, connected diagnostic tools into the field — and airflow is where most comfort complaints start. This one-day, in-person seminar gives working technicians hands-on mastery of the Digital TrueFlow Air Handler Flow Meter, an IoT-enabled instrument for measuring airflow and static pressure in residential and light-commercial HVAC systems.

Participants spend the day working directly with the instrument: pairing it to a mobile device, running live CFM and static-pressure tests on real equipment, interpreting readings in the field, and using the TrueFlow app to turn raw data into a professional, customer-ready diagnostic report. By the end of the day, participants can independently set up, run, and document a full airflow diagnostic test — a core skill for any technician performing system commissioning, troubleshooting, or preventive maintenance.

Participant preparation

Working knowledge of residential or light-commercial HVAC systems. No prior experience with digital airflow instrumentation or IoT diagnostic tools is required.

Learning Outcomes

By the end of this seminar, participants will be able to:

  • Explain core HVAC airflow principles and why accurate airflow measurement directly affects system comfort, efficiency, and equipment life.
  • Identify the components of the Digital TrueFlow Air Handler Flow Meter and describe how it uses IoT connectivity to capture and transmit data.
  • Set up and pair the TrueFlow meter with an Android or iOS device and correctly configure it for a live test.
  • Measure and interpret cubic feet per minute (CFM) and static pressure using the TrueFlow instrument and app.
  • Distinguish system-related airflow issues from instrument or installation error when reviewing test results.
  • Diagnose common and advanced airflow faults, using case-based examples of real-world airflow problems and their resolutions.
  • Use the TrueFlow app to generate a customized diagnostic report and communicate findings and recommendations to a customer in clear, non-technical language.
