Ductless Ac systems or “mini-splits” are used for applications where ductwork cannot be installed.
You can save money on expensive installation costs by adding to an existing system. This is not considered “central air” due to the fact it cannot control whole home temperatures.
It can act as a substitute for central ac by adding more than one air handler to different areas of the building. The outside unit (condenser) will be matched to the capacity of the square footage it needs to cool or heat.
Typical applications are used in Florida rooms, Garages, Computer rooms, and add-on rooms. They can save the customer a ton of money by eliminating the need for an additional split system to be added to the property.
They are also controlled by a remote control thermostat, rather than one on the wall. Remotes can also adjust the airflow by controlling the veins at the front of the air handler unit.
