In a scenario where a technician is examining inadequate supply air from registers, which technician's actions were correct?

The correct answer indicates that both technicians' actions were necessary to address the issue of inadequate supply air from registers. In situations involving heating systems, it is crucial to consider multiple factors that could contribute to airflow problems. Each technician may have focused on different aspects of the system that could affect performance.

For instance, one technician might have checked the supply ductwork for blockages, ensuring that air could flow freely from the furnace to the registers. Simultaneously, the other technician may have evaluated the registers themselves, inspecting for physical obstructions, mis-adjustments, or other issues that could limit airflow.

By taking complementary actions to fully assess and resolve the problem, the combined efforts of both technicians provide a comprehensive approach to diagnosing and fixing air supply issues. This collaborative method ensures that all potential causes are addressed, leading to a more effective and long-lasting solution for the heating system's performance.
