VentCool Vista Series Whole House Fans

A Vista Series Whole House Fan / Attic Fan is a powerful, energy efficient, quietly performing residential cooling system.

Vista series attic fans provide up to 30 air changes per hour depending on fan selection and size of house. A precooled house greatly reduces air conditioning use during the day. A Vista Series Whole House Fan is energy efficient, quietly performing residential cooling systems. Free cooling mode uses up to 90% less energy than air conditioning mode.

Vista series fans feature a highly efficient Electronically Commutated Motor (ECM) motors that operates at an optimally low cfm/watt draw consuming up to 90% less energy than traditional air conditioning. Vista models also feature an exclusive PowerSeal Motorized Damper with R-49 insulation. PowerSeal dampers are designed for a secure, precise, and insulated seal between the attic and the living space when operation of whole house fan is not desired.

Vista series whole house fans are rated and tested to Home Ventilation Institute Standard HVI-916 and can be used to comply with 2016 Title 24 Part 6. These house fans are also eligible for the Home Energy Renovation Opportunity (HERO) financing program.

What is the difference between a whole house fan vs attic fan? Attic fans help prevent the transfer of heat from a hot attic to the living space below. An attic fan is installed in the attic and blows hot air from the attic out through a roof-level vent. Using an attic fan can reduce the temperature in the attic by up to 50 degrees and reduce the temperature by as much as 10 degrees in the living space below the attic.

A whole house fan is installed in the ceiling, usually in a central location. The fan draws in cooler evening air through open windows and pulls warm air from the home’s living space, blowing it into the attic. Whole house fans can provide up to 30 air changes per hour depending on the home’s floor plan, the climate, and fan size. This results in enough air to cool a home in approximately one hour. Once the sun rises and outdoor temperatures increase, the fan is shut off and the windows are closed to preserve the cooler air until the evening.
