Ductless Mini-Split Systems
Heating and Cooling Systems Without Ductwork.
 Ductless heating and cooling systems can be a good choice for room additions where extending or installing distribution ductwork is not feasible, and for older homes without air ducts.
A ductless HVAC system operates like a conventional heat pump. The difference is that instead of a single indoor unit distributing heated or cooled air through ductwork, a ductless mini-split system has multiple small units serving individual rooms or zones. The term "mini" refers to the small indoor air-handling units.
Efficient Heating and Air Conditioning. Since mini-splits have no ducts, they avoid the energy losses associated with ductwork of central forced air systems—which can be as high as 30%, especially if the ducts are in an unconditioned space such as an attic.
Advantages of Ductless Mini-split Systems. The main advantages of mini-splits are their small size and flexibility for heating and cooling individual rooms. Many models can have up to four indoor air-handling units connected to one outdoor unit. Each zone has its own thermostat, so you can condition each space individually, saving energy and money. The biggest disadvantage of ductless mini-split systems is their cost, which can be about 30% more than central systems and may cost twice as much as window units of similar capacity.
But for certain applications, a ductless mini-split heating and cooling system may be your best option—especially if you’re retrofitting a non-ducted home or space.
