Efficient Dual Ventilation

Whole House Fans and Attic Fans are the dynamic duo of cooling. These two systems work together to keep your whole house cooler. Operating your WHF in the cool mornings and evenings cools the entire thermal mass of your home. During the day the attic fans work hard continuing to exhaust the hot air out of your attic helping to alleviate the burden of heat on your home. Together or separate these ventilation appliances are the most energy efficient cooling systems you can invest in with the highest return on investment

Sizing The Right System For Your Home

We use a general formula of either 2, 2.5, or 3 Cubic Feet per Minute (CFM) per square foot of living space. 2 CFM would provide a good system, 2.5 CFM would provide a better system, and 3 CFM would provide the best system. Whether installing a central or zoned system for your home there are other considerations such as attic clearance & ventilation which can be determined during our free estimate. To calculate how much CFM you may need in your home, simply use the CFM Calculator.
