A mini split AC indoor unit is a type of air conditioning system that consists of two separate units: an outdoor compressor/condenser and an indoor air handler. The outdoor unit is responsible for cooling the air, while the indoor unit is responsible for distributing the cooled air throughout the home. Mini split AC indoor units are an ideal choice for homes that don’t have existing ductwork or where ductwork is difficult to install. They are also more energy efficient than traditional central air conditioning systems, as they don’t require a large amount of energy to cool a single room. Mini split AC indoor units are also much quieter than traditional systems, making them a great choice for homes with multiple occupants. They are also more flexible, as they can be used to cool multiple rooms in a home, as opposed to a single room with a traditional system.
