Why Proper Ventilation Matters for WA Homes
Living in Mercer Island, WA , you understand the importance of maintaining comfortable indoor temperatures year-round. Attic fan installation play a crucial role in indoor air quality, especially in our WA environment.
Attic fans operate by creating airflow that removes hot 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 Mercer Island 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.
