Assessing HVAC system efficiency often involves checking airflow and temperature differentials, which are critical indicators of how well the system is operating. By measuring the temperature of the air entering and leaving the system, one can determine if the system is effectively transferring heat. If the temperature difference is not within expected ranges, it may suggest issues such as poor airflow, refrigerant problems, or malfunctions in system components.

This method allows technicians to pinpoint inefficiencies and make necessary adjustments or repairs. The focus on airflow is particularly important, as blocked ducts or inadequate airflow can heavily impact system performance and comfort levels within a space. Overall, analyzing these differentials provides valuable insights into the efficiency and effectiveness of an HVAC system.
