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. Ductwork is an essential component of a home's HVAC (heating, ventilation, and air conditioning) system, responsible for delivering conditioned air to the various rooms in a house. The ductwork connects the furnace, air conditioner, or heat pump to the registers and vents in each room, allowing the HVAC system to effectively heat or cool the entire home.
Well-designed ductwork is crucial for ensuring even temperature distribution, efficient airflow, and proper ventilation throughout a home. Properly sized and installed ductwork can also help to improve indoor air quality, reduce energy costs, and extend the lifespan of the HVAC system.
