Ductless

 A ductless AC unit, also called a ductless mini-split HVAC unit, ductless mini-split heat pump, ductless AC, or simply a ductless mini-split, is a type of heating and cooling system consisting of an outdoor heat pump and indoor wall or ceiling-mounted unit. A ductless AC unit works the same as a traditional heat pump system, except it doesn’t require ducts! Each area of your home is equipped with an individual air handler, which controls heating and cooling output within that space, making these a popular option for spaces like attics or additions.

Ductless systems run rather quiet compared to a central HVAC system. Since there are no ducts, there is no sound produced by the air moving through the ductwork itself.

Traditional HVAC systems with ductwork account for up to 30 percent of energy lost in the cooling process. With a central air conditioner, this is a problem you may face, especially if your ducts require sealing. A ductless unit could save you up to 30 percent on your cooling costs immediately by eliminating the ductwork.
