About Line Sets

Line sets for HVAC use are pre-insulated copper tubing lines that connect the outdoor air conditioning or heat pump unit to the indoor evaporator coil. They typically come in two parts, an insulated suction line and an insulated liquid line. The insulation helps reduce condensation on the outside of the pipe and provides better temperature control within your home’s living spaces. Line sets have a variety of sizes available depending on the needs of your HVAC system and they are easy to install with minimal tools required.
