A whole house fan is usually installed on the attic floor near the center of your house.
Always a fan in attics.
As hot air rises to the top fans push the hot air out and cool down the home by drawing in the fresh air.
Because of the attic s location it is always a hotter part of the house.
An attic fan on the other hand is a fan that exhausts only attic air out of the attic vents.
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.
I am the first to say the installation of an attic fan is not always recommended.
This prevents hot air from seeping into your home and driving up the temperature in the living space which reduces the load on your air conditioner.
Cooler outdoor air enters through open windows lowering the indoor temperature.
With energy costs higher than ever many homeowners are looking for ways to reduce their bills while still keeping the whole house cool.
This will help to avoid premature damage to the shingles or mold building up in moist hot.
An attic fan works by exchanging the hot air in your attic space for fresh air pulled through the vents.
Attic ventilation fans help cool air your attic by pushing out the stifling hot air from inside the attic and bringing in cool air from outside.
With an attic fan that switches on appropriately when the attic reaches a specific degree somewhere between 105 120 degrees fahrenheit it serves to push the hot air out of the house and to help cool your home the upstairs bedrooms can drop in temperature by almost 10 degrees.
Some can have manual switches while others use a thermostat to turn them on and off automatically.
Even though an attic exhaust fan can incrementally lower the temperature of a very hot attic using a fan does not stop the source radiant heat.
During the day any cooler air brought in by the fan will be heated up immediately by the surrounding structure.
Attic fans are installed at the roof level of your home to regulate the heat level.
In the late evening or early morning the fan is turned on to exhaust hot air from the house.
But there are times when the installation a unit can be beneficial but it depends on several things 1 proper installation 2 proper conditions environmental factors 3 on a lesser note whether it is a diy installation or a professional installation which is costly and hence possibly not cost effective.
Attic fans come with different models.
Attic gable fans roof mount attic fans and solar attic fans.
They can help you save a lot of money on your energy bills as you may not have to use air conditioning if the weather isn t too hot.
Most fans cannot keep up.
