A whole house fan is a simple and inexpensive method for cooling homes, improving ventilation and reducing energy bills. The fan works by drawing cool outdoor air through your home and exhausting hot indoor air through the attic to the outdoors. The result is lower temperatures, lower energy bills, better ventilation and improved evaporative cooling.

The system can be used as the sole means for cooling in many climate zones or in combination with central air conditioning. When in use with air conditioning systems, seasonal use often increases efficiency.

Building Solutions installs whole house fans that are sized to draw adequate airflow through the house to exchange air within 10 minutes. All units are insulated and mechanically sealed when not in use to exceed Title 24 requirements (R-38).
