A ducted mini split system is a type of air conditioning system that uses two separate units, an outdoor condenser and an indoor air handler, to provide cooling and heating to a space. The outdoor condenser is connected to the indoor air handler via two refrigerant lines, one for cooling and one for heating. The air handler is then connected to a series of ducts, which are used to distribute the cooled or heated air throughout the space. The main benefit of a ducted mini split system is that it is a highly efficient way to heat and cool a space, as the air is distributed directly to the areas that need it, without the need for additional ductwork. Additionally, these systems are typically quieter than traditional air conditioning systems, as the outdoor condenser is located outside the space, and the indoor air handler is much smaller than a traditional air handler. Finally, these systems are often more cost-effective than traditional air conditioning systems, as they require less energy to operate.
