A venting system is a network of pipes and ducts designed to remove unwanted gases, odors, and moisture from a building. It helps maintain indoor air quality by allowing fresh air to enter while expelling stale air. Commonly found in homes and commercial buildings, these systems can include exhaust fans, vents, and air ducts. Properly functioning venting systems are essential for safety, as they prevent the buildup of harmful gases like carbon monoxide. They are also important for reducing humidity, which can lead to mold growth. Regular maintenance ensures that the venting system operates efficiently and effectively.
