Attic Fan Temperature And Humidity Settings

That said attic fans are not the best choice for cooling attics especially if you have central air conditioning.

Attic fan temperature and humidity settings.

Most manufacturers and contractors recommend a temperature setting between 100 and 110 degrees fahrenheit. Our answer attic ventilators generally turn on between 90 and 110 degrees fahrenheit. This prevents snow from melting on your roof and freezing when it hits the cold gutter. In particularly hot climates set the temperature higher to keep the fan from running for extended periods of time.

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. When it comes to adjusting the thermostat of your attic s fan it s best to adjust it to approximately 90 to 95 degrees. Humidity settings are another issue that can make or break the performance of your heating and cooling systems and your attic ventilation.

The normal indoor humidity range in winter should be 15.
