Put your hand near a running crawl space vent fan and there’s no mystery about whether air is moving. You can hear the motor, feel air passing through the opening, and see the blades turning. From a few inches away, the fan can seem like it’s doing exactly what it’s supposed to do. The more important question is what happens to that airflow once we move away from the opening.<\/span><\/p>\n That’s how we approach Vent Fans in Alpharetta. At Crawl Space Ninja,<\/a> we look at where the fan is installed, which direction it’s moving air, where replacement air can enter, and what happens as we move deeper beneath the house. If you’re considering a Vent Fan or want an existing fan inspected, contact us online<\/a> to schedule an inspection.<\/span><\/p>\n A crawl space Vent Fan doesn’t operate independently from the air outside the foundation. That’s particularly important during Alpharetta’s warm, humid summers, when outdoor conditions can be considerably different from cooler parts of the year. The fan continues doing the same mechanical job even as the air around the house changes.<\/span><\/p>\n The house itself matters, too. A crawl space beneath an established home closer to Canton Street may be divided differently from one we enter farther south around North Point. Foundation walls, additions, ducts, plumbing, and the overall footprint can change the paths available for air beneath the floor. That’s why we need to get underneath the house before making assumptions about airflow.<\/span><\/p>\n \nAlpharetta’s Outdoor Air Doesn’t Stay the Same<\/span><\/h2>\n
