Comparing Ductless & Ducted Air Conditioning Did you know that there are two types of air conditioning systems? Daikin Group has a comprehensive lineup of both ductless and ducted systems ranging from homes to large-size facilities including offices, stores, and buildings. Utilizing the features and strengths of each type, Daikin offers a wide range of solutions to match every environment. Indoor units are placed in each room for individual heating and cooling. Each indoor unit operates independently to enable individual temperature settings. Air is sent through ducts from one central location to heat and cool all rooms. All rooms are air conditioned uniformly at the same temperature settings. Independent control allows temperature adjustment of environments with infants and elderly people along with situations needing adjustment during the day. Central control provides the convenience of a uniform environment and is suited for environments that remain largely constant during the day.
