London Plumbing & Remodeling: Whole House Fans: Keeping cool in Summer

In previous postings we looked at attic ventilation and ceiling fans. What is the difference between an attic fan and a whole house fan? The attic fan is designed to keep temperatures in the attic lower. By keeping the attic cooler less heat pushes down through insulation and the ceiling and this keeps your living space cooler.
The whole house fan is a different type of fan. Usually installed in the hall it operates by exchanging the hotter air inside of your home for the cooler outside air. The best time to use your whole house fan is in the evening when it cools off (thru the night if you like) and early in the morning before it gets too hot.
By opening the windows (and turning off the A/C) we draw cool fresh air into the house and vent it into the attic. In addition to cooling the house it also cools the attic helping to keep energy costs down. The whole house fan is usually two speeds and by running a motor (or fan) and not using the A/C the house is kept cooler at a lower energy cost.
These fans require some real effort to install and often we need to bring power to the appliance in the attic. In addition to significant time and experience to install these units we need to make sure that the attic has enough venting in the gables & eaves so that we can exhaust the hot air quickly. Without enough venting the whole house fan will not be as efficient as it should be.
Whole house fans come in a variety of styles & costs. Considerations are amount of air we need to move, noise and cost of fan & installation. These fans start in the $200.00 range up to $1600.00 or more. The more expensive units are quieter, have insulated doors and are usually energy star rated.
