Ductless systems have always been more energy efficient than central forced-air systems. In fact, distribution energy loss in typical forced air systems has been estimated to be as high as 40%, while estimates for energy loss in ductless systems range from 1% to 5%. While typical systems generally cap out at 18 SEER, Cooper&Hunter ductless systems, most of which are ENERGY STAR qualified, can achieve up to 23 SEER, greatly reducing utility bills. Additionally, since the cooling and heating of indoor zones can be managed independently, less energy is wasted in unoccupied spaces. Thanks to their operational efficiency and zoning capabilities, ductless mini splits waste less energy overall and, thus, have a smaller carbon footprint. Furthermore, C&H systems use R410A refrigerant, an eco-friendly option that doesn't deplete the ozone layer.
