Collection: Line Sets

Line sets for Mini Split Systems. A line set is a pair of insulated copper tubes that connect the outdoor condensing unit to the indoor air handler or evaporator coil in a split system air conditioning or heat pump system.

Most line sets need to be charged with refrigerant by a licensed HVAC technician. One brand, called MRCOOL, has revolutionized the industry by offering pre-charged line sets. This patented technology by MRCOOL saves the end consumer from lengthy and pricey services from HVAC technicians. Without having to charge the unit with refrigerant, most handymen and women can install these mini split systems all by themselves!
