![]() ![]() Floor-standing models are also available. The indoor air handlers can be suspended from a ceiling, mounted flush into a drop ceiling, or hung on a wall. Duct losses can account for more than 30% of energy consumption for air conditioning, especially if the ducts are in an unconditioned space such as an attic.Ĭompared with other add-on systems, mini-splits offer more flexibility in interior design options. Since mini-splits have no ducts, they avoid the energy losses associated with ductwork of central forced air systems. This makes it possible to cool rooms on the front side of a building house with the compressor in a more advantageous or inconspicuous place on the outside of the building. So, if necessary, you can locate the outdoor unit as far away as 50 feet (~15 meters ) from the indoor evaporator. Also, most manufacturers of this type of system can provide a variety of lengths of connecting conduits. For example, the hook-up between the outdoor and indoor units generally requires only a three-inch (~8 centimeter ) hole through a wall for the conduit. Each of the zones will have its own thermostat, so you only need to condition that space when it is occupied, saving energy and money.ĭuctless mini-split systems are also often easier to install than other types of air conditioning systems. The number depends on how much cooling is required for the building or each zone. This can be affected by how well the building is insulated and air sealed. Many models can have as many as four indoor air handling units (for four zones or rooms) connected to one outdoor unit. The main advantages of mini-splits are their small size and flexibility for zoning and cooling individual rooms. ![]()
