The installation does not have many drawbacks. You'll find that the typical cost of an average fully installed attic fan will vary based on motor rating, fan dimension, mount type, overall finish quality, and labor rate. There are passive (wind) power solutions and traditional types of electric motors. A do-it-yourself installation is more economical because you only have to pay for the fan.
However, you should make a hole in the roof and seal it properly afterwards. This may require new roofing materials, which will increase costs. For reference, attic fans are not the same as ceiling fans, which are mounted on the ceiling of a room and circulate the air in the room. Roof attic fans are electric or solar and are usually installed under the ridge at the back of the home.
A qualified fan installer will be able to calculate the required ventilation area for your particular fan. A passive attic fan is an affordable, energy-efficient option that works even during a power outage. However, it's beneficial to have a fan in the attic and an air conditioning unit in your home to work together and cool the house. You may even find that something as simple as increasing the thickness of the insulation and providing more natural ventilation in the roof space will give you the same benefits as an attic fan.
The fan is mounted on the attic floor above a grille in the ceiling of a central room, such as a hallway. Depending on the size of the fan you install, a whole-house fan could cost you more each month on your home's energy bill. An attic fan of any type is safe as long as it also places emergency cut-off switches and ensures sufficient ventilation to prevent drafts. We'll share the estimated retail cost of the unit itself, as well as the cost of having the attic fan installed by an electrician, operator, or HVAC company.
Solar attic fans cost nothing once installed, and the installation may qualify for federal and state tax incentives. It helps you keep track of the attic temperature so you know if the fan should work or if there are any problems. The cost of installing an attic fan is affordable enough to be a definite consideration when trying to keep your home cool. You can also clean the fan shutters that open regularly and wash the fan blades to ensure that the device continues to work properly.
If you have the skills, tools, experience and time, you can install passive attic fans yourself and save on labor costs.
