The Science Behind Attic Airflow and Energy Savings
As a Purcellville resident , you understand the importance of keeping your home cool year-round. Effective cooling systems play a crucial role in indoor air quality, especially in our regional weather patterns .
Attic fans operate by facilitating air movement that expels heated air from your attic space. When temperatures rise, upper levels can hit 130-160°F , which forces your HVAC system to consume more energy.
Understanding how attic ventilation works is essential for Purcellville homeowners who want to maximize their energy efficiency investments. When hot air becomes trapped in your attic, temperatures can reach 140-160°F during summer months, creating a massive heat load that radiates down into your living spaces.
