The answer to 'how does ductwork work' is that ductwork is the system of pipes and vents that distributes heated or cooled air throughout a building. Ductwork is an essential component of HVAC (heating, ventilation, and air conditioning) systems, as it transports the air from the furnace, air conditioner, or other heating/cooling equipment to the various rooms in a home or building.
The ductwork is typically made of metal, such as galvanized steel or aluminum, and is designed to efficiently move air through the system. The ducts are connected to registers or vents in each room, allowing the conditioned air to be evenly distributed. The size, shape, and layout of the ductwork are carefully designed to ensure optimal airflow and temperature control throughout the building.
