What is a line set?

A line set is a copper tube used to connect the indoor air conditioning unit to the outdoor condensing unit, for the purpose of moving refrigerant through the system. Although these are small accessories, this is an essential component to complete the installation of any ductless mini-split system or unitary split system. Due to maintenance issues, when replacing old units it’s important to also replace the line sets. You don’t want to have a completely new system with 20-30 year old components. If you have any questions about selecting the correct line sets, please email
