What is a mini-split system?

A mini-split system is a type of ductless HVAC solution that enables zoned heating and cooling, which means that it can regulate the temperature in individual rooms or zones independently. This system consists of an outdoor compressor unit and one or more indoor air handling units that are connected by refrigerant lines. The absence of ducts allows for greater flexibility in installation and can lead to improved energy efficiency, as conditioned air is delivered directly to the living spaces.

Mini-split systems are particularly advantageous in situations where extending ductwork is impractical, such as in retrofitting buildings or in spaces like small apartments and homes where separate climate control is desired. The ability to control temperatures in different zones leads to enhanced comfort and can result in reduced energy consumption, as users can heat or cool only the areas that are occupied.
