A duct free split system is a type of air conditioning system that is becoming increasingly popular due to its efficiency and cost-effectiveness. It is a type of mini-split system that does not require any ductwork, making it easier to install and maintain. The system consists of two main components: an outdoor condenser unit and an indoor air handler. The condenser unit is installed outside the home and is responsible for removing heat from the air. The air handler is installed inside the home and is responsible for circulating the cooled air throughout the home. The two components are connected by a refrigerant line, which allows the system to transfer heat between the two components. The duct free split system is a great option for those looking for an efficient and cost-effective way to cool their home.
