Refrigerant Line Sets

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. Line sets come in several lengths and are designed to be cut to fit your exact need. We offer line sets for both standard central air conditioning systems and heat pumps, as well as mini-split systems. Mini-split line sets can be used with any brand of mini-split equipment. 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.

In 2002 Alpine Home Air Products became the first company to sell heating, air conditioning and indoor air-quality products online. We have proudly served hundreds of thousands of customers, helping them save time and money by buying their products direct.
