The Science Behind Attic Airflow and Energy Savings
Living in Erwin, TN , 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 .
These systems work by promoting air circulation that eliminates stagnant air from your attic space. When temperatures rise, roof spaces can exceed extreme temperatures , which makes your air conditioning to work harder .
Understanding how attic ventilation works is essential for Erwin 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.
