Course Overview

This Advanced A/C Training Class is designed for technicians who want to stay ahead of industry changes driven by new refrigerants and component technology. The evolution of refrigerants has changed not only system efficiency but also the way diagnostics and repairs must be performed.
This is a course specific to the diagnostics of Modern A/C Systems.

Level: 2

1. Fooled by Pressure Readings Only

  • The dangers of relying on pressure readings in isolation for system diagnosis

  • How pressure can be misleading: effects of ambient temperature, refrigerant type, and system load on pressure readings

  • Why pressure should be cross-checked with temperature, superheat, subcooling, and airflow readings

  • Common mistakes made when diagnosing based solely on pressure

  • Case studies: Real-world examples where pressure alone gave a false diagnosis

2. Temperature A/C Diagnostics

  • The relationship between temperature and pressure: understanding pressures at different temperature points in the system

  • Common temperature-related issues:

    • Low evaporator temperatures indicating possible undercharge or airflow restriction

    • High condenser temperatures pointing to poor heat rejection or airflow issues

  • Temperature checks at various points: compressor inlet, evaporator, condenser, and refrigerant lines

  • Diagnosing thermal overloads, faulty expansion valves, or issues with refrigerant charge based on temperature anomalies

3. Pressure Diagnostics

  • Identifying normal vs. abnormal pressure readings for various conditions (ambient temperature, load, etc.)

  • Common causes of pressure anomalies: restricted airflow, refrigerant charge issues, compressor problems

  • Using pressure diagnostics to detect system faults: blockages, leaks, or malfunctioning components

4. Understanding the Modern A/C System

  • Advanced designs and features in modern systems: variable speed compressors, inverter technology

  • Differences in R134a and R1234yf and other newer refrigerants: pressure, efficiency, and compatibility considerations

  • The role of the system’s control board and sensors in optimizing performance

5. New Air Conditioning Components

  • Smart sensors and diagnostic tools: pressure transducers, temperature sensors, and electronic expansion valves

  • Integrated circuit boards and advanced diagnostics: what they monitor and control

  • The shift towards modular systems: flexibility in design and installation

Participants will Receive:
