What Is Better: An Attic Fan Or A Whole House Fan?
The best type of fan for your home depends on your specific needs.
- Attic fans are best for removing hot air from the attic only. They are most effective in hot, dry climates where there is a significant difference between the daytime and nighttime temperatures. Attic fans are typically less expensive to install and operate than whole house fans.
- Whole house fans are best for cooling the entire home and attic. They work by pulling in cool air from outside through open windows and exhausting hot air out through the attic. Whole house fans are most effective in cooler climates where the nighttime temperatures are low enough to cool your home, they can be more expensive to install and operate than attic fans but are up to 90% less expensive to run than air conditioning.
Below is a summary of the the pros and cons of attic fans and whole house fans:
