How to Choose Attic Fans
Airflow Capacity
When choosing an attic fan, look for its airflow capacity measured in CFM (Cubic Feet per Minute). A higher CFM means better ventilation. For most homes, a fan should have at least 1500 CFM to effectively reduce heat buildup. If your attic is larger, aim for 3000 CFM or more.
Coverage Area
Determine the coverage area your fan can handle. Most attic fans have a specified maximum square footage they can cool. For instance, a fan that cools up to 3400 square feet will work well for larger attics. Check your attic size and compare it to the fan’s coverage area.
Power Source
Consider the power source of your attic fan. Most models run on standard 120 volts. However, some models use less energy or have variable speeds. These options can save money on electricity. Look for fans with adjustable speeds to customize airflow based on your needs.
Thermostat Features
A built-in thermostat allows for automatic operation. Look for fans that include an adjustable thermostat to maintain your desired attic temperature. This feature allows the fan to turn on and off based on the attic temperature, saving energy and ensuring consistent airflow.
Noise Level
Check the noise level of the attic fan. Some fans operate quietly, while others may be noisy. A fan with a lower RPM usually runs quieter, making it suitable for residential areas. Aim for an attic fan that has noise ratings or customer reviews regarding sound levels.
