A ductless air conditioner or mini split is an air conditioner or heat pump system that consists of at least one indoor unit and an outdoor unit. These two units can typically be installed with little disturbance to the existing construction of a home or place of business. Because of their ease to install they are great options to add air conditioning and/or heating to an existing building as there is no ductwork to run through the ceilings, walls or floors. Making it a great compliment to this existing living room.
