Ultra-quiet VentCool Whole House Fans (WHF) cool naturally by replacing hot indoor air with cool outdoor air. VentCool fans use about one tenth the electricity of a typical air conditioner and reduce utility costs.
The VentCool Whole House Fan system is activated via a wall switch or optional remote control. When the whole house fan is engaged, louvered dampers automatically open to draw cool air in through home and into attic. Outside air is pulled into the home through open windows, and stale warm air is exhausted through the attic vents. VentCool Whole House Fans feature multi-speed, low wattage, Electronically Commutated Motors (ECMs) that move large volumes of air. Fans are installed away from the ceiling opening using insulated, noise dampening flex duct. VentCool fans deliver optimum energy efficiency and ultra-quiet operation.
VentCool whole house fans are the ultimate in simplicity. They are quiet, powerful, and efficient. We offer a simple range of sizes and configurations. Select the appropriate VentCool whole house fan system for any home.
A Whole House Fan will cool your home naturally by pulling cool air from open windows and exhausting hot air through the attic and roof. Used when the outside air is cooler than inside air, a Whole House Fan is effective in increasing ventilation, promoting cooling and saving energy dollars.
