What is an AC lineset?

An AC lineset, short for air conditioning lineset, is a crucial component of an air conditioning system. It consists of two copper pipes that connect the indoor and outdoor units of the AC system. One pipe carries refrigerant from the outdoor unit to the indoor unit, while the other pipe carries refrigerant back from the indoor unit to the outdoor unit. The lineset also contains insulation to prevent condensation and energy loss. AC linesets come in various lengths and diameters to accommodate different installation requirements. They are an essential part of the overall refrigeration cycle, enabling the transfer of heat and maintaining the efficiency of the air conditioning system. Proper installation and sizing of the lineset are essential for optimal AC performance and cooling efficiency.
