Mini-Split System Line Sets
Hitachi LS143814-15 Line Set
Line sets consist of two semi-flexible copper pipes to connect the outdoor air conditioner or heat pump to the indoor air handler. The smaller pipe is called the liquid line. The larger pipe is referred to as the suction line. Both the suction and liquid lines are insulated on mini-split line sets. The liquid line diameter can be 1/4, 3/8 or 5/8 inches, and the suction line can be 1/2, 5/8 or 3/4 inches depending on the size and efficiency of the air conditioner or heat pump.  When installing refrigeration lines make sure you have the correct size line set based on the specifications of the unit. Line sets come in several lengths and are designed to be cut to fit your exact need. Want to cover up the line set outside your home so it blends in with your home's exterior? Check out our line set covers which will hide the line set and preserve your home's tidy look.
