The best attic exhaust fan can keep your home cool and comfortable especially during the hottest days. It will also help protect your roof and reduce your energy costs. But finding the best attic exhaust fan can be challenging if you don't know what features to consider. Not sure where to start? Here are the most important factors to think about:
Type
When you start shopping for attic exhaust fans, you will notice that there are actually a lot of types to choose from in different designs, with different features and varying benefits. Some of the most popular types are attic gable fans, solar attic fans, and whole house fans.
Build material
The attic is usually the hottest part of the house especially in the summer. That's why you have to consider build material when finding the best attic exhaust fan. Don't buy fans that have cheap plastic components because they can get brittle and easily damaged under high temperature. Choose one that’s made from high-quality metal materials that can withstand the excessive heat in the attic and hold up against moisture.
Added features
Many features are added to attic exhaust fans to make them easier to use. Some of the best attic exhaust fans have programmable thermostats. A fan with this feature automatically turns on whenever the temperature in the attic has reached a certain level. This way, you can cool down your home the moment it starts getting hot. And thanks to this feature, you won't have to go up to your attic to switch the fan on!
Space
The
effectiveness and efficiency of your attic fan are influenced by its size. To
determine the right size to buy, you need to figure out the size of your attic
floor. Usually, a 1000 square-foot attic space needs 700 CFM to achieve proper
ventilation. However, if the attic has a steep roof, then the recommended size
will be 840 CFM per 1000 square feet.
