Eco-Friendly, Budget-Smart Cooling: Whole-House Fans as an AC Alternative

The article explains that a whole-house fan installed in an attic can pull cool outdoor air through open windows and vent it into the attic, offering a cheaper and greener cooling option than a traditional HVAC system. Installation costs typically run about $900–$2,400 compared with $7,500–$14,500 for a new HVAC, and the system can reduce energy use—especially when used with an AC—but it’s best in climates with cool evenings and may be less effective in humid or very hot conditions; proper installation is crucial to avoid pests or moisture.
