Ductless split-system air-conditioners combine the zoning flexibility of a conventional room unit (a single air-conditioner installed through a wall or a window frame) with the whole house cooling potential of central systems. Like central systems, they have two main components: a compressor/condenser, as well as an air-handling unit, which contains an evaporator and a fan. Some units operate as heat pumps and provide both summer cooling and winter heating. The noisy compressor and condenser are housed as one unit and located outdoors. The quiet fan/evaporator unit is indoors, located in the area to be cooled. A conduit, which houses the power cable, refrigerant tubing, suction tubing, and condensate drain, links the outdoor and indoor units.
The term, "split-system," also describes some central air-conditioners and heat pumps. If you ask about ductless, split-system air-conditioners, make sure the dealer understands which system you are talking about. Another common term for ductless split-systems is "mini-splits."
The advantages of ductless split-systems over room and central air-conditioners are: easy installation, quiet operation, versatility in zoning and design, and security. The split systems also eliminate the loss of cool air as it passes through the ductwork.
A key advantage of split systems is their ease of installation. Hook-up requires only a three-inch hole (7.62 centimeters) in the wall for the conduit. Unlike with central air conditioning, you do not need ductwork. Since the compressor in most ductless split-systems is as much as 50 feet (15.24 meters) away from the indoor evaporator, it is usually possible to cool rooms on the front side of the house, while still hiding the compressor in a less conspicuous area. The compressor units also fit well on flat commercial building rooftops.
Ductless split-system air-conditioners operate relatively quietly, since the compressor is outside and the evaporator unit's fan generally runs at a low speed. Variable speed high efficiency fans are also available.
When compared to other add-on systems, split-systems also provide better interior design options. The air handlers can be suspended from a ceiling, mounted flush into a drop ceiling, or hung on a wall. Floor-standing models are also widely available. Most indoor units are low-profile models, no more than seven inches (17.78 centimeters) deep, and come with decorative jackets. Most new models come with a remote control unit as standard equipment. This allows the positioning of air-handling units high on a wall or suspended from a ceiling, without compromising convenience.
Unsecured room air-conditioners provide an easy entrance for intruders. Split- systems are more secure than window units since there is only a small hole in the wall.
