HVAC Contractor in Sacramento Shares How a Whole-house Fan Works
Homeowners who are familiar with ceiling fans and box fans often have questions. How does a whole-house fan work? Does their design give them advantages over other cooling systems?
Top Rank, an HVAC company in Sacramento will answer all of these questions! As professional whole-house fan installers, they aim to explain how a whole-house fan cools a home cleanly and efficiently.
How Does a Whole-house Fan Work? The Basics
Whole-house fans cool the home by pushing hot air in the attic out of the home through a system of vents. As the air leaves the house, cooler outdoor air enters the house through the windows. The fan reduces both the ambient air temperature and the core temperature of the house itself while improving air quality.
Comparing Whole-house Fans to the Alternatives
The best way to understand, “how does a whole-house fan work?” is to compare it to air conditioning.
Conventional air conditioners use refrigerant chemicals to cool the air. The cooling process takes energy, leading to a higher electric bill. The outdoor air that the fan uses is already cooler than the air in the attic, so it does not require any additional energy to cool.
Whole-house fans cool every square foot of your house by drawing cool air upward toward the attic. This prevents your attic from being sweltering on hot days. A cooler attic means storage space that is safer for family belongings.
A whole-house fan needs outside air to keep homes cool effectively and safely. This means that when turning on the whole-house fan, homeowners should have many open windows and not close them as they would when using air conditioning.
Whole-house Fans Need Adequate Airflow
One critical feature of whole-house fans is their need for airflow. HVAC contractors can measure airflow in terms of cubic feet per minute (CFM). Before installing a whole-house fan, it is important to calculate the amount of airflow and the size of the attic vents you need in your attic roof for air to flow through.
