Single zone mini-split systems are a type of ductless heating and air conditioning system ideal for spaces that don't have existing ductwork or for areas that require zone temperature control. They consist of two main parts: an outdoor condenser unit and an indoor air handling unit mounted on the wall. Single zone mini-split systems cool and heat a single room efficiently, and many models are rated Energy Star for their efficiency. Some features you might find on a single zone mini-split system include remote control, heat pump functionality, sleep mode, and smart home assistant compatibility.
