WHAT IS A DUCTLESS MINISPLIT SYSTEM? Mini-splits have two main components: an outdoor compressor/condenser and an indoor air handling unit. Like central systems, a conduit, which houses the power cable, refrigerant tubing, and a condensate drain, links the indoor and outdoor units.
WHAT ARE THE MAIN ADVANTAGES? Mini-splits are small in size and very flexible for zoning because no ductwork is needed for heating and coolingindividual rooms or areas. Each unit has its own thermostat, so it can be adjusted to the preferred temperature.
WHAT ARE THE BEST APPLICATIONS? Mini splits can be effectively used in both residential and commercial buildings. They are currently most commonly used in multi-family housing or retrofit as add-ons to homes with "non-ducted" heating systems. They can also be a good choice for room additions and small apartments, where installing ductwork (for a central air-conditioner or heating systems) is not feasible or practical. Other opportunities for effective use include school classrooms, perimeter cooling for office buildings, additional cooling for office buildings, additional cooling for restaurant kitchens and cooling for small offices. They can also effectively cool smaller areas within larger spaces, such as arenas, warehouses or auditoriums.
ARE THEY ENERGY EFFICIENT? Since mini-splits have no ducts, they avoid the energy loss associated with the ductwork of central forced air systems. Duct loss can account for more than 30% of energy consumption, especially if the ducts are in a non-air conditioned space, such as an attic.
CAN THEY HEAT ANDCOOL? Yes. Ductless mini split-systems are available in both air conditioner and air conditioner / heat pump models.
