Installation requirements vary significantly between central and multi split systems. Central air conditioning requires a network of ducts that need to be integrated into the property’s structure, which can be invasive and typically requires significant construction work. This makes it more suitable for new builds or major renovations where ducting can be included in the initial design stages. The central unit itself is usually placed in an out-of-the-way location like an attic or basement. Multi split systems, in contrast, require minimal structural modification, as they do not use ductwork. An outdoor unit connects to one or more indoor units via small pipes that require only small holes to be drilled through the walls, making the installation process far less disruptive. Each indoor unit is typically mounted on the wall or ceiling and can be placed in strategic locations based on the cooling needs of each room. This system is particularly advantageous for adding air conditioning to existing buildings or extending systems without major renovations.
