How to Choose Attic Fans
Airflow Capacity
Choose an attic fan with at least 800 CFM airflow for proper ventilation in smaller spaces. Larger attics may need fans with 1500 CFM or more. A good rule is to match the fan’s CFM rating to your attic size, aiming for 1 CFM for every square foot.
Installation Type
Consider whether you want a gable mount or wall-mounted fan. Gable-mounted fans, like the iLiving ILG8G14-12T, are usually easier to install and provide better airflow. Wall-mounted fans are often more affordable but might require more maintenance.
Energy Efficiency
Look for fans with low wattage but high airflow. A fan that uses less than 100 watts while providing over 1000 CFM is a great choice. Check for features like adjustable thermostats to help save energy.
Noise Levels
Select fans specifically designed for quiet operation if noise is a concern. Look for specifications mentioning low decibel ratings. This is especially important in residential areas where noise could disturb neighbors.
Control Options
Choose between manual and automated controls. Fans with thermostats and humidistats, like the Quietcool models, will adjust automatically to temperature and humidity. This adds convenience and helps maintain optimal attic conditions.

Frequently asked questions
What is an attic fan?
An attic fan is a device that helps to ventilate your attic. It removes hot air, helping to keep your home cooler.
How does an attic fan work?
An attic fan pulls hot air out of your attic and brings in cooler outside air. This helps lower temperatures, especially in the summer.
Is attic fan worth it?
Many homeowners find that having an attic fan can reduce cooling costs. It helps maintain a comfortable temperature in your home.
How do I choose the right attic fan?
Look for airflow capacity, installation type, energy efficiency, noise levels, and control options to find the best fit.
Do attic fans need maintenance?
Yes, attic fans should be checked regularly. Clean dust and debris from the blades and ensure the motor is functioning properly.
What to look for
Airflow Efficiency
Airflow efficiency is critical in an attic fan. Aim for a fan with at least 800 CFM for smaller spaces, but larger attics may require 1500 CFM or more. Proper airflow helps regulate temperature and humidity, reducing strain on your HVAC system.
Fan Material
The material used in the fan’s construction affects durability and performance. Look for fans made of galvanized steel or high-quality plastic. Steel fans tend to last longer and withstand outdoor conditions better than plastic models.
Thermostat Features
Many attic fans come with adjustable thermostats. This feature allows the fan to turn on automatically when the attic reaches a certain temperature. Choose a fan with a thermostat range between 50º to 120º for optimal performance.
Noise Level
Consider the noise level produced by the fan. Models designed for quiet operation usually have lower decibel ratings. If you are sensitive to noise or live in a quiet neighborhood, this feature is particularly important.
Size and Installation Type
The size of the attic fan affects its effectiveness. Gable-mount fans provide better airflow and are easier to install. Ensure the fan you choose fits your attic space and is rated for the area you intend to cover.
