Plan Your Summer Cooling and Fresh Air Needs Now

"This time of year, a whole house fan allows a home to 'breathe' by pulling in fresh, healthy outside air and pushing out stale unhealthy air, pet odors, and gasses from toxic household products through vents in the roof.

Colasanto admitted that: "There is some confusion about how a whole house fan works and even what it is. A whole house fan is not a ceiling fan, a window fan or an attic fan even though it's often centered in an attic."

He also cautions that there is a lot of confusing information about a fan's airflow, normally stated in Cubic Feet per Minute(CFM). "Most people think moving higher CFMs of air is better but that's not always the case. House size -- which can be calculated on our web site -- and the correct 'net free opening' in an attic are the two most important considerations when purchasing the best fan for your home. The net free opening is especially significant in the summer when much hotter attic air can be forced back into the home if it can't escape quickly enough. We frequently see consumers purchasing 6,000CFM units for smaller homes – bigger is better right? – not realizing that they need sixteen square feet of opening in the attic for the fan to do its job. In effect, they have purchased an inefficient and costly fan unable to produce the desired benefits."

Other purchasing considerations according to Colasanto: "The best whole house fans seal out hot or cold air leakage when not in use; offer R38 or R50 insulation that complements the attic's existing insulation; operate for pennies a day; and offer remote access via 'smartphone'. Prices range from around $400 to over $1,600 reflecting a wide variety of features," he concluded.
