Most homeowners see 50-90% reduction in air conditioning costs during suitable weather conditions. A whole house fan costs just pennies per hour to operate compared to dollars per hour for central AC.

Whole house fans work best when outdoor temperatures are cooler than indoor temperatures, typically during evening, night, and early morning hours. They're most effective when the outdoor temperature is 82°F or below.

Solatube's EPS series features HushMount 2 patented technology for ultra-quiet operation. Sound levels range from just 40-48 dB on the EPS Zone model - quieter than most air conditioning units while providing superior cooling.

Solatube provides comprehensive warranty coverage: 10-year warranty on all mechanical components, 15-year warranty on the fan motor, and Limited lifetime warranty on all housing materials. This gives you complete peace of mind in your investment.

Yes, you need to open windows on the lower level of your home to allow fresh outdoor air to enter. This creates the airflow pattern that pulls cool air through your living spaces and exhausts hot air through the attic.
