Venting systems are essential components in buildings that help remove unwanted gases, odors, and moisture from indoor spaces. They work by allowing fresh air to enter while expelling stale air, ensuring a healthy environment. Common types of venting systems include exhaust fans, chimneys, and ventilation ducts. These systems are crucial for maintaining air quality and preventing issues like mold growth and indoor air pollution. Properly designed venting systems can enhance energy efficiency and comfort in homes and commercial buildings, making them an important aspect of modern construction and design.
