Most homes are serviced by traditional air conditioning systems with a single condenser/compressor, a single air handler, and a single evaporator coil, it's a greater system.
But some floor plans and home layouts make consistent heating and cooling difficult. Sometimes, the additions of a room can throw the balance off. That's when Daikin mini-split air conditioning units come to the resuce.
A mini-split system can either supplement or replace a traditional central air system. The heart of a mini-split system is the condenser/compressor - the outside unit. Here, refrigerant is compressed and circulated back inside the house, much like a traditional unit would do. But instead of supplying a single evaporator coil, the condenser supplies refrigerant to multiple air handlers/evaporator coils, which service individual rooms (zones) in the house.
