The following lines were added (+) and removed (-):
== Refrigerant Line Sets ==The coolant line set runs externally to connect the separate air handler and exterior compressor unit and transport the coolant between the two components. This line-set consists of two copper lines. Line sets consist of two semi-flexible copper pipes to connect the outdoor air conditioner or heat pump to the indoor evaporator coil. The smaller pipe is called the liquid line. The larger pipe is referred to as the suction line, and includes insulation.* Large Line = Suction Line, which feels cold to the touch while unit is operating in AC. It carries the coolant as a gas and this line should be insulated the entire length to help prevent the coolant from heating up due to the exterior temperature.* Small Line = Liquid Line (also called the pressure line), which feels hot to the touch while unit is operating in AC. Carries liquid coolant between the two units, this line gets very hot when operating due to the coolant being put under pressure. This line should not be insulated.
