Some of the work we do

Whole House Fans

Cooling strategies
In the summertime, the air inside a home is heated during
the hot part of the day. At night especially, and during the
morning and late evening, the outside air is often cooler and
can be used to replace the inside air. It is important to open
all or at least several windows, even if only partially, to
provide adequate airflow. Closing windows in unused rooms
will create higher velocity air movement in occupied rooms.
Running the whole house fan whenever outdoor
temperatures are lower than indoor will cool the house.
Operate the whole house fan throughout the evening to cool
interior materials. An approximate rule of thumb would be to
use the whole house fan when outside temperatures are
below 85°F. As daytime temperatures rise, turn off the
whole house fan.
