A ductless mini split system uses two main units, the indoor unit and outdoor unit, to provide conditioned air. Indoor units, or air handlers, install inside the home or building and distribute the cool air. Depending on the type of unit, the air handler may wall or ceiling mount directly in the room you wish to cool. The outdoor condenser installs outside of the home and releases the warm air from the home.

The ductless mini split air conditioning system works well in homes without ducts, like older homes or apartments. A single zone system uses one condenser and one indoor unit. A multi-zone system uses one condenser and up to four air handlers depending on the unit.

Mini split systems control the temperature in a single or multi-zone space. Central systems typically can control the temperature of an entire home or building and use ductwork to transfer air.

Package terminal air conditioners, also called PTACs, install directly through the wall. As a single unit, a PTAC requires only the unit itself. They do not require ductwork. Traditionally, they work in hotels, but they can also see use in dormitories, senior centers, and other similar locations.
