How Much Does An Attic Fan Help

An attic fan may not reduce your air conditioning costs but a whole house fan is a different story.

How much does an attic fan help.

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. They can cool your home in less than an hour. One better option for you is to seal and well insulate the ductwork and the unit itself check the owners manual for clearances needed especially for gas units. They can cool your home in less than an hour.

However if your attic has blocked soffit vents and is not well sealed from the rest of the house attic fans will suck cool conditioned air up out of the house and into the attic. Because you ll usually need two fans to create the results you want instead of a single traditional product your expenses are going to double. In such doing the attic fan will reduce the temperature in the attic space that in turn cools down the whole house. If you choose an energy star rated solar attic fan for your home then you might qualify for tax credits that equal up to 30 of your initial expense.

Of course if the attic fan isn t working correctly and is running all year long that would be a significant problem. An attic fan works by drawing in cool air to the attic space that pushes out the hot air through vents. 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. If the attic fan keeps the house cool enough so that the owners leave the ac off there is almost certainly an energy benefit.

As stated above an attic fan can enable you to turn up your ac thermostat by as much as 10 degrees. Just make sure you have the right climate to use one.
