The Science Behind Attic Airflow and Energy Savings
Living in Lewiston, ME , you understand the importance of maintaining comfortable indoor temperatures year-round. Effective cooling systems play a crucial role in indoor air quality, especially in our regional weather patterns .
Ventilation systems function by creating airflow that removes hot air from your attic space. In hot weather , upper levels can hit 130-160°F , which makes your air conditioning to operate less efficiently .
Attic ventilation plays a crucial role in maintaining optimal home comfort and energy efficiency throughout Lewiston and the broader ME region. When your attic lacks proper ventilation, it becomes a heat trap that forces your air conditioning system to work significantly harder, resulting in substantially higher energy bills and reduced indoor comfort. Recent studies by the Department of Energy indicate that homes with inadequate attic ventilation can experience cooling costs that are 15-40% higher than properly ventilated homes.

The Hidden Benefits of Attic Airflow
The process of moisture accumulation in attics occurs when warm, humid indoor air meets cooler surfaces in an unventilated attic space. During winter months in Lewiston, this can create ice dams that damage roofing systems and gutters. In summer, trapped moisture combined with high temperatures creates ideal conditions for mold and mildew growth. Professional attic ventilation systems eliminate these moisture problems by maintaining consistent airflow that prevents condensation and humidity buildup.
