A split duct AC system is a type of air conditioning system that utilizes two separate units to cool a space. The two units are the outdoor condenser and the indoor evaporator. The condenser is located outside the home and is responsible for removing heat from the air and transferring it to the outdoor environment. The evaporator is located inside the home and is responsible for cooling the air and then circulating it throughout the home. The two units are connected by a series of ducts that run between them. The ducts allow the cooled air to be circulated throughout the home. This type of system is often more efficient than traditional air conditioning systems and can be used to cool multiple rooms in a home. It is also a great option for those who want to save energy and money on their energy bills.
