What is the definition of a supply house mini split? A supply house mini split is a type of air conditioning system that consists of two parts: an outdoor compressor/condenser and an indoor air handler. The two parts are connected through refrigerant lines, which allows the system to transfer heat and cooling energy between the two components. This type of air conditioning system is becoming increasingly popular due to its energy efficiency and cost savings, as well as its flexibility in installation and design. Supply house mini splits are typically split into two separate units, with one unit located outside and the other located inside. The outside unit will contain the compressor and condenser, while the inside unit will contain the evaporator and fan. The indoor unit is usually mounted on the wall, while the outdoor unit is usually located near the home’s exterior. The units are designed to be extremely energy efficient, as the air is transferred directly through the line set, eliminating the need for ductwork and registers. In addition
