Attic Fan Temperature And Humidity Settings

Humidity settings are another issue that can make or break the performance of your heating and cooling systems and your attic ventilation.

Attic fan temperature and humidity settings.

The fans cool the attic equalizing the temperature between the attic and outside of the home. Our answer attic ventilators generally turn on between 90 and 110 degrees fahrenheit. Most attic fans operate with a thermostat that automatically turns the fan on and off based on a temperature the homeowner sets. Most manufacturers and contractors recommend a temperature setting between 100 and 110 degrees fahrenheit.

When it comes to adjusting the thermostat of your attic s fan it s best to adjust it to approximately 90 to 95 degrees. This prevents snow from melting on your roof and freezing when it hits the cold gutter. Of course some environments are much hotter than others so this will be the perfect time to measure out how warm your attic will get during the most heated of seasons. The normal indoor humidity range in winter should be 15.

In particularly hot climates set the temperature higher to keep the fan from running for extended periods of time.
