The Healthy Home System™ for air that is Fresh, Clean, & Pure
Breathe air that is Fresh, Clean, & Pure.™
VentCool Whole House Fans are the ultimate in Free Cooling. They are quiet, powerful, and efficient. We offer a complete range of sizes and configurations for any application. With the Whole House Fan engaged, louvered dampers automatically open to draw in cool night-time air into the home through open windows, and stale warm air is exhausted through the attic vents.
A Whole House Fan will cool your home naturally by pulling in 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.
