In addition to proper insulation in your attic, there are other improvements you can make. Adding an attic fan can increase ventilation and provide benefits all year long, not just in the summer. While a whole house fan can help to provide ventilation throughout the home, an attic fan may be more appropriate for your situation. Ask your contractor if you aren’t sure.
Call the ventilation experts at ACI Northwest for more information about how to help weatherize your home for year round comfort and efficiency. To get you started, we have included some of the main ways that attic fans can improve overall home efficiency and prevent moisture problems in the home.
Creating more fresh air circulation in your attic not only helps cool the home in the summer, but it can also prevent moisture related damages. In a home that is already well-insulated and has plenty of ventilation, an attic fan will help with overall efficiency by helping to remove the hot air from the attic. In addition to keeping the home cooler in the summer, it removes the heat that rises to the attic in the winter.
You don’t want all the heat in your home trapped in the attic during the winter because it will speed up the snow melting process. If temperatures drop quickly, the snow melt can freeze and create ice dams. Ice dams can cause damage to your roof, and when they start to melt, the water can get under the shingles and into your attic. This can ruin the insulation, wood, and even dry wall and ceilings if the leak is serious enough.
