Copper Lines & Kits

Built for HVACR service, these ACR-grade copper options connect your outdoor condenser to the indoor coil for new installs, changeouts, and repairs. DIY-capable homeowners can plan clean runs, while licensed contractors and property managers will appreciate durable materials and budget-friendly pricing from about $65 to $519. Choose soft copper rolls for custom-length refrigerant lines or line sets for fast, consistent installs across residential and light commercial jobs.

Correct sizing protects performance. Match suction and liquid line diameters to your equipment’s BTU/tonnage and follow manufacturer piping charts to help maintain rated SEER2 efficiency. Keep total equivalent length and vertical lift within spec, and insulate the suction line to minimize capacity loss. Line sets and rolls don’t change voltage or stages, but they do influence oil return, sound, and charge balance-key factors in real-world efficiency.

These copper lines are compatible with common HVAC refrigerants when installed to code, including legacy and current blends such as R-410A and newer A2L refrigerants (e.g., R-32/R-454B). Professional installation is recommended for brazing, evacuation, and charging; nitrogen purging, proper flaring, and torque help prevent leaks and oxidation. Some kits include insulation and fittings, while soft roll bundles are often bare copper-review product details for what’s included.

Frequently Asked Questions

  • What size soft copper roll do I need for my AC or heat pump line set?

    Select suction and liquid line diameters based on system BTU/tonnage and the manufacturer’s piping chart; length and lift also influence sizing.

  • Are these copper rolls suitable for mini-split installations?

    Yes. Many mini-splits use small-bore lines (commonly 1/4" x 3/8" or 1/4" x 1/2"); confirm the exact sizes, flare specs, and refrigerant requirements for your model.

  • Can I flare and braze this copper myself or should a pro install it?

    Cutting and insulating are DIY-friendly, but brazing, evacuation, and charging should be performed by a licensed pro to meet code and protect warranties.

  • What refrigerants are compatible with these copper lines?

    ACR copper is compatible with common HVAC refrigerants, including R-410A, R-22, and newer A2L blends (e.g., R-32/R-454B) when installed per code and OEM guidance.

  • How do I determine the correct line length and diameter for my system?

    Use your equipment’s engineering data: match line sizes to tonnage and reference maximum equivalent length/vertical lift; adjust charge as specified.

  • Do these copper line kits include insulation and fittings?

    Line sets often include pre-insulated suction lines and flare nuts; soft copper rolls are typically bare copper. Check product details for inclusions.

  • What are the recommended bending and handling practices for soft copper lines?

    Use a tubing bender, maintain proper bend radius, avoid kinks/ovality, keep ends capped, and purge nitrogen during brazing to prevent scale.

  • Are these products approved for light commercial applications?

    Yes. ACR-grade copper is suitable for residential and light commercial systems when sized, installed, and pressure-tested to applicable codes.

  • How do I keep my system’s SEER2 rating with new lines?

    Follow OEM line sizes, limit equivalent length, insulate the suction line, evacuate thoroughly, and charge precisely to maintain rated efficiency.

  • What lengths are available and how do I choose?

    Soft rolls and line sets commonly come in 25', 50', and 100' lengths. Choose the measured run plus modest slack for routing, avoiding excess coil.
