Attic Fan Turn Off Temperature

I recently bought a house that has an attic fan on a thermostat that seems to run whenever the outside temperature gets above about 70.

Attic fan turn off temperature.

The attic has about 2 3 of blown in cellulose is pitched i don t know the pitch but it s about average for a typical suburban house and has a gable vent on each end l shaped house. In particularly hot climates set the temperature higher to keep the fan from running for extended periods of time. Attic fans come with different models. Most manufacturers and contractors recommend a temperature setting between 100 and 110 degrees fahrenheit.

Some can have manual switches while others use a thermostat to turn them on and off automatically. Open your windows before you turn on the fan. When it comes to adjusting the thermostat of your attic s fan it s best to adjust it to approximately 90 to 95 degrees. The house was constructed in 1958 and is 2x6 wood frame on 16 centers.

Most attic fans operate with a thermostat that automatically turns the fan on and off based on a temperature the homeowner sets. Cooler outdoor air enters through open windows lowering the indoor temperature. What temperature should attic fan be set at. 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 the temperature within the attic reaches a set point the fan will turn on and start venting the heated air cooling the attic space. Typically these devices are used in summer when the temperatures are high exceeding 49 degrees celsius. Likewise adjustable thermostats will shut the fan off.
