The Science Behind Attic Airflow and Energy Savings
As a San Tan Valley resident , 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 local climate conditions .
Attic fans operate by creating airflow that expels heated air from your attic space. During summer months , attic temperatures can reach extreme temperatures , which forces your HVAC system to work harder .
Attic ventilation plays a crucial role in maintaining optimal home comfort and energy efficiency throughout San Tan Valley and the broader AZ 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.
