Mini-split ductless air conditioning system
Option for those without existing ductwork
A split AC system uses at least two pieces of hardware. The air-handler units containing the evaporators and blowers are installed inside your home, while the compressor unit is installed outside. Split systems are more expensive to buy, but potentially cheaper to install, and a ductless system is practical for homes that don't already have ductwork. The big advantage of a ductless mini-split system is that you can adjust temperature levels for individual rooms or areas. Split systems require more maintenance than single-box central air conditioners, however.
