Line Sets from Cedars HVAC connect a split air conditioner or heat pump’s indoor and outdoor units with insulated copper refrigerant tubing. A standard set pairs a smaller liquid line with a larger suction line, often in combinations such as 1/4 with 3/8, 1/4 with 1/2, or 3/8 with 5/8 inch. Pre-insulated line sets are used for ductless mini splits and conventional split systems, with length, flare or sweat connection style, and insulation thickness selected for the installation. Match both copper diameters and maximum run guidance to the unit manufacturer’s specifications, especially for R-454B equipment and legacy R-410A systems. Cedars HVAC offers contractor-friendly quantities for multi-system projects.
