Measuring HVAC Indoor Airflow

In this course, we cover multiple methods to measure indoor airflow. This is one of the most overlooked aspects of air conditioning. If the airflow is too low, it could result in excessive run times, high electrical costs, and cause the indoor coil to freeze. In furnaces, the low indoor airflow causes the furnace to overheat and excessive wear and tear of components.
