Split system air conditioning can work well when you want to heat or cool a particular room without conditioning the entire home. It can be used in living areas, bedrooms, home offices and other spaces where individual temperature control is useful. The challenge is finding a system that suits the space. Capacity, room layout, insulation, windows, sunlight, how the room is used and the available installation locations can all affect the choice. Before selecting a model, it is worth looking at these practical considerations alongside features, installation requirements, running costs and ongoing maintenance.
