The answer to 'difference between ductwork and' is that ductwork and ductless systems are two different approaches to heating and cooling a home. Ductwork refers to the network of metal or insulated ducts that distribute heated or cooled air throughout a home, while ductless systems use individual wall-mounted units to provide targeted heating and cooling without the need for extensive ductwork.
Ductwork is commonly found in traditional forced-air HVAC systems, where a central furnace or air conditioner sends air through the ducts to vents in each room. Ductless systems, also known as mini-split systems, have an outdoor compressor unit that connects to one or more indoor air-handling units, allowing for more flexible and efficient heating and cooling in specific areas of the home.
