If yes turn it off.
How to turn on attic fan.
For all of you who are struggling with that question how to turn off the attic fan there are two ways to do this.
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.
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.
The house was constructed in 1958 and is 2x6 wood frame on 16 centers.
You could either go up to the attic and check if the fan has a switch.
Likewise adjustable thermostats will shut the fan off.
That pool of heated air.
Knowing how to troubleshoot common problems that could befall your fan will help you make simple repairs.
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.
A thermostat is used to automatically turn the fan off and on while sometimes a manual switch is used.
This fan would be installed on one end of the house while the opposite end already has an open screened vent thus air would be drawn in from one end and expelled out the other.
A powered attic ventilator or attic fan is a ventilation fan which regulates the heat level of a building s attic by exhausting hot air.
Attic fans come with different models.
After the attic fan has been in use for some time it may develop problems.
If the fan in the attic does not have a switch you will have to turn off the circuit breaker that controls the fan in the attic.
The main work of an attic fan is to regulate the heat level of the attic by removing hot air out of the attic and pushing it outside providing needed ventilation.
Additional vents are required to draw in fresh air as the hot air is exhausted.
A hot summer day super heats the attic s air raising temperatures up to 150 degrees fahrenheit making cooling your home a losing battle.
So the theory behind the attic fan was to be able to turn it on as the outdoor temps cool in order to clear the hot air out of the attic space.
An attic fan can be gable mounted or roof mounted.
An attic fan is a great way to keep your home cool during the hot summer months.
