PRODUCT DESCRIPTION

  • Extend the coverage of your HVAC line sets with our Residential Series Galvanized & Unpainted HVAC Line Set Cover Extensions. These premium quality extensions ensure a seamless and durable finish, providing unlimited linear coverage for your HVAC installations.

    • Premium Quality: Made from 26 gauge materials, our extensions offer superior protection. The paintable steel is ready for any exterior latex paint without the need for priming or sanding. Our G-90 galvanized steel is hot dipped for long-lasting durability, and our Galvalume is acrylic coated to withstand harsh outdoor environments. Fabricated and shipped in the USA.

    Multiple Sizes

    • All extensions are made in 5 FT sections, available in widths of 4" x 4", 6" x 4", 6" x 6", and custom widths upon request. The 6" x 4" size is 6 inches wide and 4 inches deep.

    Simple and Easy Installation

    • Designed to easily fit over the line set cover for a smooth, overlapping connection. The tapering design allows the extensions to telescope with our Residential Series Galvanized & Unpainted Metal HVAC Line Set Covers for a seamless finish. Each order includes matching sheet metal screws to secure the seams.

    Multiple Materials and Colors

    • In addition to galvanized and unpainted steel, we offer extensions in various materials such as 16 ounce 24 gauge pure copper, 26 gauge painted steel, 26 gauge stainless steel, and aluminum diamond tread plate. Explore our full Metal HVAC Line Set Cover Extensions Collection for more options.
    • Fabricated from the exact same 26 gauge materials as our Galvanized & Unpainted Line Set Covers for a consistent and seamless finish.
    • Note: Actual line set cover extension color may differ due to varying monitor settings. Please contact us for color samples or additional photos.

    All product prices include free Standard Shipping in the Lower 48 States.

        Comfort That Speaks for Itself

        See why homeowners and pros alike trust MRCOOL DIY systems to deliver comfort, savings, and easy installation.

        I never thought I’d install my own HVAC system, but MRCOOL made it possible. The instructions were easy, and the pre-charged lines saved me from hiring a tech. Cools my garage workshop perfectly!

        Jason R., North Carolina

        Our MRCOOL mini-split runs really quiet — you can barely tell it’s on. Our electric bill dropped about 35% this summer. Very impressed with the efficiency

        Megan L., Arizona

        Installed this in my detached office. Took me a Saturday morning and a friend to lift the outdoor unit. Works flawlessly — heats in winter and cools in summer.

        Daniel P., Texas

        I swapped my old central unit for two MRCOOL DIY mini-splits. Same comfort, way lower bills. The inverter technology really makes a difference.

        Jennifer C., Florida

        Had a small question during installation and Vanessa picked up right away. They walked me through it step by step — best customer service I’ve had in years.

        Chris B., Ohio

        Keeps our sunroom comfortable in 100°F summers and comfy in the winter. The heat pump feature is amazing — one system for both heating and cooling!

        Angela K., Kentucky

        I’ve remodeled a few homes, and MRCOOL DIY systems are a game-changer. No need for HVAC pros or special tools — everything is plug-and-play.
