The Science Behind Attic Airflow and Energy Savings
For homeowners in 21108, you understand the importance of keeping your home cool year-round. Attic fan installation play a crucial role in energy efficiency , especially in our MD environment.
Ventilation systems function by creating airflow that eliminates stagnant air from your attic space. When temperatures rise, roof spaces can exceed dangerous levels, which causes your cooling system to work harder .
Understanding how attic ventilation works is essential for Millersville 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.
