4.2 USING YOUR QUIETCOOL ATTIC FAN
Attic fans are designed to cool and ventilate your attic all year long. Depending
on the month of the year, you will want to change the temperature setting of your
thermostat.
SUMMER MONTHS
In the summer, the attic in your home can reach temperatures in excess of 150ºF.
An attic fan is designed to cool and ventilate your attic space in the hot months of
the year to help protect your HVAC equipment, protect the integrity of your house
structure, and to prevent the heat in the attic from heating up your indoor living
space.
We recommend setting your thermostat between 80ºF and 100ºF for the most
effective cooling during the warmer months of the year.
With an attic fan running during the summer, we have seen attic temperature
maintain as low as a 5ºF difference between the outside temperature and the attic
temperature.
WINTER MONTHS
In the winter, ice and condensation can build-up on the roof and in the attic due to
the drastic temperature difference between the outside air and the air inside the
home. This can cause major damage to your HVAC equipment as well as the structure
of your home. This is called ice damming and it is a major issue in cold climates.
With an attic fan, you can ventilate the attic space to help keep the moisture level
low and keep the attic temperature close to the outside temperature. And since heat
rises, you won’t be wasting any of the heat within your home.
We recommend setting your thermostat to 60ºF for the most effective ventilation and
protection against ice damming.
