A whole-house fan is an effective means of cooling a house, and is far less expensive to run than an air conditioner. Whole-house fans can reduce indoor temperatures by 3 to 8 degrees F, depending on the outside temperature.
Find out how a whole-house fan can save you money by cutting your air conditioner use 15 to 60 percent.
- If a well-insulated house is closed up during the heat of the day, it will heat up inside slowly like an insulated ice cube. In the evening when it’s cooler outside than inside, and you open the windows, a whole-house fan blows
the hot air out of the house. - The fan should be centrally located so that it draws air from all rooms in the house. Be sure your attic has sufficient ventilation to get rid of the hot air.
- To ensure a safe installation the fan must have an automatic shutoff in case of fire.
- Ceiling, paddle, and portable fans produce air motion across your skin that increases evaporative cooling.
- A moderate breeze of one or two miles an hour can extend your comfort range by several degrees and will save energy by allowing you to set your air conditioner’s thermostat higher or eliminate the need for air-conditioning altogether.
- Less frequent use of air conditioning by setting the thermostat higher will greatly cut cooling bills.

We are currently in the design stage of our tear down and rebuild of our home. It would seem that your product might be a good option for me. We were looking at only limited A/C use for only 2 bedrooms along with ceiling fans throughout. Since cealing fans only move the air around, and your product will pull the air out of the house, it would seems to result in a cooler house. Will your product be able to cool the whole house from one location, especially in far bedrooms with only a door?
