Ventilation is a vital, but often forgotten part of your home’s cooling and heating system. As part of the first line of defense against the elements, attic ventilation has a direct impact on the energy efficiency of your home.
Seasonal temperature swings can cause a problem in your attic if it’s not adequately ventilated.
Attics in our hot, humid summers can reach temperatures of 120 to 150 degrees Fahrenheit or more. This heat can radiate down into living areas through the ceilings, making your home unnecessarily hot.
It also makes your cooling system work harder which may lead to premature ware.
In the winter, heat that escapes into your attic can cause condensation which, unchecked, can lead to the growth of mold, potentially ruining your attic insulation, corroding wiring and other components of your home’s structure.
What makes a house more energy efficient?
If your home has energy efficient ventilation it helps your cooling and heating system do its job much more efficiently.
A good ventilation system goes hand in hand with adequate insulation throughout your home. To be energy efficient, an attic needs two sources of ventilation that provide enough air circulation while also removing excess heat and condensation build-up.
- soffit vents should be installed down low on the underside of the roof overhang to allow outdoor air into the home
- ridge, box or power vents placed at or near the roof peak allow air to escape the home
