The answer to 'what does ductwork do' is that ductwork is the system of pipes and vents that distributes heated or cooled air throughout a home. The ductwork carries air from your HVAC system to the various rooms in your house, allowing you to control the temperature and air flow. Ductwork is an essential component of any central heating and cooling system, as it ensures the conditioned air reaches all the intended areas.
Ductwork is typically made of metal, such as galvanized steel or aluminum, or flexible insulated tubing. It is designed to minimize air leaks and energy loss as the air travels through the system. Proper ductwork installation and maintenance is important to ensure efficient and effective heating and cooling in your home.
