The installation of ductless air conditioners is quite fast. Experienced installer can install a ductless unit in one day. The outdoor unit is installed outside of the room and placed on a solid surface so that it can remain stable, or on wall bracket mounted up to 10’ high on the outside wall. The indoor unit that delivers cool air is installed high on a wall or ceiling. A small 3-inch opening is made in the exterior wall through which pair of refrigerant lines connecting the two units pass. One of the refrigerant lines delivers electricity while the other takes away condensate.
Ductless air conditioners have many advantages over the central air conditioners. The first advantage is that the installation of ductless air conditioner is very simple, easy and fast since no ductwork is required. It doesn't use up window space or require large openings in the walls as the window or central air conditioners require. Thus it doesn't pose any security risk as the central air conditioners do.
