Whole house fans used to be called attic fans, and today "power vents" are the nomenclature for what many know as attic fans. They pull hot air out of the attic into the open air, which is ideal for very hot attics, a garage or space without a contained attic space, or just to work in tandem with a whole house fan.
POWER VENTS/ATTIC FANS
A Powered Vent is a fan located in an over-sized steel roof vent. A Gable Fan is located behind an existing vent on the vertical wall in the attic. Both of these smaller fans are controlled by a thermostat and can be upgraded with a humidistat. When the whole house fan is not running, the Powered Vent or Gable Fan removes hot air from the attic. When the whole house fan is running, they serve as a very effective outlet for hot air. When used in conjunction with a whole house fan, you have created the most efficient and effective home and attic cooling system available.
Powered Vents (aka Attic Fans) and Gable Fans are smaller-volume fans that are controlled by a thermostat and reduce the build-up of super-heated air in the attic. When used in tandem with a whole house fan, you have created the most comprehensive home cooling system available.
If you rely on air conditioning or evaporative cooling as your primary cooling system, Powered Vents and Gable Fans, which dramatically decrease the temperature in the attic, can help these systems to run more efficiently and also prolong the lifespan of your roof.
Give us a call to find out more about QuietCool’s amazing new Smart Gable Fan – it uses an efficient variable speed motor that works with the thermostat/humidistat – so the fan runs faster when it’s hotter in the attic, and turns on if the humidity level in the attic is over 60%.
