What is free cooling?

For a quiet cool and whole home ventilation turn to to VentCool® Whole House Fans. VentCool fans are Free Cooling Systems that replace warm/stale inside
air with cool/fresh outdoor air. Fresh, cool nighttime air
is brought in from outdoors to precool the house and its
contents (thermal mass cooling).

The benefits of free cooling begin with dramatic energy savings. VentCool® Whole House Fans use up to 90% less energy than running compressor based air conditioning units. VentCool home ventilation fans are quiet and offer whole home cooling.

VentCool fans are available in three series--Tahoe, Summit, and Vista--to meet a wide range of applications and budgets.

How it Works


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 30 to 60 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.

That's the difference between an attic fan vs whole house fan.
