Whole House Fan

Package Level: 
Silver

Air conditioning units are one of the most expensive appliances to operate in your home. But using a whole house fan, especially when coupled with the KVar unit, will easily cut these costs in half. This system will quickly flush air through your house into the attic then out through roof vents. Not only will the air movement cool you but by flushing the attic area, which gets extremely hot, you won't have that pocket of super heated air right over your head. An additional benefit is that fresh air will be replacing the stagnant air trapped inside your home. This is important because the EPA has found that indoor air quality can be up to 10 times worse than air outside. When the fan is not in use insulated doors close the system off keeping the attic sealed separately to the house
