Ductless mini splits, including ductless air conditioners and ductless heat pumps, can fit in any space, even where traditional HVAC units don’t. With their virtually endless configurations, ductless air conditioner and heat pump products deliver comfort with minimal visual impact. Ductless heating and cooling systems are different from traditional split systems because they come in all shapes and sizes, and don’t require ducts inside your walls. These wall mounted air handlers are flexible and work wherever you need them.
