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. In the late evening or early morning the fan is turned on to exhaust hot air from the house. When it comes to adjusting the thermostat of your attic s fan it s best to adjust it to approximately 90 to 95 degrees. 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.

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. Also you place it on the roof top or gable mounted. 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. Open your windows before you turn on the fan.

What temperature should attic fan be set at. Most manufacturers and contractors recommend a temperature setting between 100 and 110 degrees fahrenheit. Typically these devices are used in summer when the temperatures are high exceeding 49 degrees celsius. Most attic fans operate with a thermostat that automatically turns the fan on and off based on a temperature the homeowner sets.

Likewise adjustable thermostats will shut the fan off. The house was constructed in 1958 and is 2x6 wood frame on 16 centers. A whole house fan is usually installed on the attic floor near the center of your house.
