Heat Pump - Installation Accessories

Novair Pre-Insulated Twin Copper Refrigerant Line Set is engineered for professional heat pump and air conditioning installations requiring reliable refrigerant flow between indoor and outdoor units. Manufactured from high-purity refrigeration-grade copper tubing, this twin configuration includes both liquid and suction lines bundled together for efficient, code-compliant system connections.

The tubing is suitable for modern high-pressure refrigerants such as R410A, R32, and R454B when installed according to manufacturer specifications. Copper remains the HVAC industry standard due to its high thermal conductivity, corrosion resistance, mechanical strength, and long service life under elevated operating pressures typical of inverter-driven heat pump systems.

Each line set is factory pre-insulated with closed-cell insulation designed to reduce thermal losses, limit condensation formation, and improve overall system efficiency. Proper insulation on the suction line is critical to maintaining refrigerant superheat, preventing energy loss, and protecting against moisture damage in both heating and cooling modes. The bundled twin design simplifies installation, reduces labor time, and provides a clean, professional appearance when used with line set covers or concealed routing.

The line set is delivered unflaired to allow certified HVAC technicians to perform custom field flaring based on equipment specifications. On-site flaring ensures correct seating surfaces, proper torque application, and secure mechanical connections when paired with approved flare nuts and manufacturer torque guidelines. Standard commissioning practices including pressure testing and deep vacuum evacuation to industry micron standards are required to ensure system integrity and long-term performance.

Suitable for residential and light commercial split systems, ductless mini-splits, ducted heat pumps, and hybrid configurations, Novair pre-insulated twin copper line sets are designed for durable performance in both moderate and extreme climate conditions. Professional installation required.
