Direct-expansion split systems have the condensing unit and air handler installed in different locations
- The condensing unit is mounted in the engine room or other mechanical space.
- The air handler (also called the evaporator) is installed in the living area. Two air handlers can connect to one condensing unit.
Split system advantages
Less space needed in the living area for the air handlers. Quieter because the compressor is in the engine room. A wide selection of air handler types.
