Question: How does a ductless split or ductless mini split system work?

Ductless split systems can replace a traditional central ducted system or be used in addition to a central ducted system.

It works in much the same way as a traditional air conditioner or heat pump, using an outdoor condensing unit, indoor air handler/evaporator (fan coil) with an outdoor condenser, attached to refrigerant line sets and a condensate drain line. The condenser is installed outside the home or business typically on a code approved surface. The conduit is then run from the outdoor unit to the individual room within the structure that you choose, even an attic or garage.

Depending upon the system design, the use of wall-mounted interior units, ceiling mounted units, recessed fa coils, floor mounted air handlers are then installed and secured in the appropriately desired spaces to control cooling, heating and humidity as needed and designed.

One or a series of indoor units and refrigeration lines are used to transfer the cooled air from the outdoor condenser to the indoor units of your choice. It works in reverse with heated air in the winter. Units can be placed in any rooms you like and because each unit is individual, you control the specific temperature in that room instead of needing to set one thermostat for the entire house. As a result, you save money by cooling or heating only the space you are using.

One of its greatest advantages is TRUE ZONING!
