A central air conditioning system utilises a single large unit, usually installed in the basement or loft, which distributes air through a series of ducts throughout the property. This system is ideal for providing a uniform temperature across large spaces. It’s especially suitable for new constructions or properties undergoing major renovations, where duct installation can be planned from the start. In contrast, a multi split system consists of one external unit that connects to multiple indoor units, each of which can be controlled independently. This setup allows for different temperatures in different rooms, providing personalised comfort and increased energy efficiency.
The choice between these systems largely depends on the specific needs of the property and its occupants. Multi split systems offer more flexibility and are easier to install in existing buildings since they do not require ductwork. This makes them particularly appealing for retrofitting in older homes or in buildings where preserving the interior aesthetics is important. Central air conditioning systems, while less flexible in terms of individual zone control, can be more aesthetically pleasing as all components are hidden away, with only discreet vents visible.
