A whole house fan is an inexpensive and simple 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 utility bills, lower temperatures, and increased ventilation. In many climate zones in California a whole house fan can be used as the sole means for cooling or in combination with central air conditioning.
The Building Doctors 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).
