Why Proper Ventilation Matters for CA Homes
As a Sunnyvale resident , you understand the importance of maintaining comfortable indoor temperatures year-round. Effective cooling systems play a crucial role in energy efficiency , especially in our regional weather patterns .
Attic fans operate by facilitating air movement that eliminates stagnant air from your attic space. During summer months , upper levels can hit extreme temperatures , which causes your cooling system to consume more energy.
Understanding how attic ventilation works is essential for Sunnyvale 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.
