Measuring the temperature of the refrigeration components at certain points around the A/C system allows the technician to verify the changes occurring within the system.Table 4.1 provides a guide to the temperature of the refrigerant flowing through the components within the A/C system.

Measuring the temperature of the air flowing inside the vehicle at certain points allows the technician to ensure the blend and air distribution system is functioning correctly. Placing temperature probes and varying the blend door position allow the technician to verify the available temperature range the system is capable of delivering and how quickly the range can be delivered. Measuring the temperature and rate of air flowing at different ventilation points tests the air distribution positions.
