The air filter is usually located in the return air duct or blower compartment before the return air reaches the air handler. Since the ahu is the central unit that moves the air throughout the ductwork it is important to make sure nothing obstructs the airflow through the air handler such as dirty or clogged air filters. A clogged air filter might have been the cause of the frozen evaporator coils in the first place. This allows the filter to clean the air coming from your house before it enters the hvac unit.
