Installing Attic Fan To Cool Down My house

During warm summer days, the temperatures in your attic (hot roof) should be between 15-20 degrees higher, resulting in cooler temperatures inside the house. Poor inadequate insulation and poor ventilation temperatures in the attic can range from 120-150 degrees. To help lower energy costs an attic fan can help also lower temperatures inside your home up to 5 degrees with an appropriate sized attic fan.
