System 1 aircon connects one indoor unit to a single outdoor condenser. It’s best suited for cooling a single room such as a bedroom, study, or home office. This setup is both energy-efficient and cost-effective—ideal for smaller spaces or individual room use. Popular brands include Daikin, Mitsubishi Electric, Panasonic, and LG.
A System 2 aircon links two indoor units to one outdoor unit, making it an excellent option for HDB flats or condominiums with two bedrooms. It cools multiple rooms efficiently while conserving outdoor space. This configuration is ideal for 3-room flats or small families. Leading brands include Daikin, Panasonic, Midea, and Fujitsu.
As Singapore's most popular configuration, a System 3 aircon powers three indoor units from one outdoor condenser. It is ideal for 4-room HDB flats or 3-bedroom condominiums for midsized families. It balances energy efficiency with whole-home comfort. Trusted brands include Mitsubishi Electric, Toshiba, Daikin, and LG.
For larger households or commercial use, System 4 and System 5 support four to five indoor units through a single condenser. This allows individual room control and better energy optimisation. System 4 aircon is ideal for landed properties, large condos, offices, or retail units. Recommended brands include Mitsubishi Heavy Industries, Samsung, Daikin, and Panasonic.
