Split systems are the most common type of central AC, using ductwork and a mechanical blower to distribute air. It’s split because refrigerant is circulated between an indoor unit (housing the coil) and an outdoor unit (housing the condenser and compressor). Indoor and outdoor units must be properly matched for compatibility and efficiency. Some types, such as heat pump styles, offer both heating and cooling.
