Refrigerant Copper Line Sets

Refrigerant Copper Line Sets

Refrigerant copper line sets are essential HVAC accessories that connect the indoor and outdoor components of air conditioning and heat pump systems. These copper tubing sets carry refrigerant between the evaporator coil and the condenser, enabling efficient heat transfer for cooling and heating performance.

They are used in residential, commercial, and light industrial HVAC installations, including split systems and heat pump applications. HVAC365 ships nationwide, so whether you are a homeowner replacing a line set or a contractor installing new split systems across multiple job sites, you can order from a stocked catalog and have product delivered to your location.
