Line Sets

Line sets are preassembled copper tubing systems used to connect indoor and outdoor components of air conditioning, heat pump, ductless mini-split, and refrigeration systems. Typically consisting of insulated suction lines and liquid lines, line sets facilitate refrigerant flow between evaporators, condensing units, and compressors while helping maintain system efficiency and performance. Available in a variety of diameters, lengths, insulation thicknesses, and application-specific configurations, line sets support residential, commercial, and light industrial HVACR installations.
