Planning an air conditioning installation for your home involves more than selecting a unit. The right system depends on your home's size, layout, insulation, electrical capacity, how you use each room and your future plans. Whether you need a split system for one room, a multi-head system for several areas, ducted air conditioning for whole-home comfort or a more discreet bulkhead system, the right option depends on what suits your property and how you use it. This guide covers the main system types, installation considerations, costs and other factors to consider before arranging an assessment.
