Like conventional HVAC systems, ductless, mini-split AC systems locate the noisy compressor and condenser outside the house. It eliminates the need for a basement- or attic-located evaporator unit and bulky ductwork by using thin copper tubing that pumps refrigerant directly to discreet wall mounted blowers inside. Even more remarkable, this system works in reverse in winter, absorbing heat from the outside air and moving it indoors to heat your home. The result? Efficient cooling and heating for year-round, whole-house comfort. Systems are available in numerous mix-and-match capacities and configurations, for even the most difficult to heat and cool areas.
