Understanding Attic Ventilation: The Foundation of Energy Efficiency
Living in Decatur, AL , you understand the importance of maintaining comfortable indoor temperatures year-round. Attic fan installation play a crucial role in energy efficiency , especially in our regional weather patterns .
Attic fans operate by promoting air circulation that eliminates stagnant air from your attic space. In hot weather , roof spaces can exceed dangerous levels, which causes your cooling system to operate less efficiently .
Understanding how attic ventilation works is essential for Decatur 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.
