Considerations When Choosing Loft Fans

Attic fan style

There are two main fan designs for loft cooling. The first design is a whole house fan. These fans draw air through the entire house and trap air in the attic. By moving cool air around the room, the fan also cools the attic.

The second design is called a roof fan. These fans remove hot air from the attic and draw in cooler air. A roof fan is a more direct way to cool the attic, while a whole house fan is more indirect.


Roof fans are mounted either on the roof or in a gable. In either case, the installation will require you to work in a sensitive environment where altitude can be limited and heat can be excessive.

While roof access is unlikely to be required to install a gable, safety is still incredibly important. If you’re not comfortable installing an attic fan yourself, hire a professional to do it for you.

Cubic feet per minute

This is perhaps the most important figure to consider when shopping for an attic fanatic. The cubic feet per minute (CFM) of a fan refers to the amount of air that the fan actually moves. The larger the house or attic, the larger the desired CFM. Some fans are dual-speed fans, which means you are actually getting two different CFM numbers.


Some fans are equipped with thermostat controls. These are helpful because they take the guesswork out of running your attic fan. The controls are usually mounted on a cable that is a reasonable distance from the fan blades. This makes for a more accurate reading because the thermostat is away from the fan itself, where the air is more static.

Square footage

Before buying an attic fan, consider the area of ​​your home as well as your attic. Manufacturers often claim that their fans can operate in areas between 1,000 and 3,000 square feet. However, you can also find small, less expensive loft fans to handle smaller loft spaces of 500 feet or less. However, CFM is likely a more reliable number to base fan performance on than manufacturer-supplied square footage.

Solar vs. standard

Solar roof fans are readily available in the consumer market. They are efficient because they don’t need electricity to function. Solar fans don’t have many drawbacks as they work basically the same as standard fans. However, one detail to look out for is CFM as many solar roof fans have a lower CFM than standard roof fans.


Most attic fans cost anywhere from $ 50 to $ 400. Fans between $ 50 and $ 200 typically cover a smaller area, up to 1,500 square feet. Fans that cost $ 200 are often said to be cooling 3,000 square feet or more.


Q. Can I install my own roof fan or do I have to use a professional?

A. That depends on your level of comfort on DIY projects. While professional installation is always preferable, most roof fans can be installed by the homeowner without any significant difficulty.

Question: what is venting?

A. Venting replaces hot air with cooler air as it is drawn out of the attic. If you do not replace the hot air that is escaping, you can create a pressure relief. This actually pulls cool air from the rooms below, making the house even warmer.
