The Science Behind Attic Airflow and Energy Savings
Living in Harriman, TN , you understand the importance of managing energy costs year-round. Attic fan installation play a crucial role in energy efficiency , especially in our regional weather patterns .
Attic fans operate by facilitating air movement that expels heated air from your attic space. In hot weather , roof spaces can exceed 130-160°F , which causes your cooling system to work harder .
Attic ventilation plays a crucial role in maintaining optimal home comfort and energy efficiency throughout Harriman and the broader TN 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.
