                              4 Reasons to Get A Zoned Whole House Fan System

                              ZONED (MULTI-FAN) SYSTEM

                              Allows the homeowner to have complete control over their ventilation and cooling needs with a multi-zoned system. A zoned system’s total CFM requirements are met by adding the cumulative CFM of all zoned units, not by adding the CFM of each zoned fan individually. Zoned fans can be used simultaneously to cool a large area of a residence. However, a zoned system provides for more precise airflow management in each individual bedroom.
