Better for outdoor aesthetics where a 4″ decorative PVC cover is desired. Constructed from durable PVC, it protects line sets and hoses from weather while hiding unattractive components. Easy to install with a direct connection between straight and flexible sections, making it suitable for homeowners seeking a quick visual upgrade. Caution: Check compatibility with Pearwow 4″ decorative kit to ensure a proper fit with your lines.

Choose this if you need a longer straight section for indoors or outdoors. The kit uses PP material and includes a painted-ready surface, enabling a seamless match with exterior walls. It is designed to organize lines and cords while expanding the life of the AC installation. Best for longer exterior runs where a paintable surface helps achieve a built-in look. Caution: Verify the 1.35 ft straight duct length if you need a longer run.
HOXHA 3″ 10Ft Line Set Cover Kit
Durable PVC line set cover with included components for a complete installation, including straight ducts, connectors, and a flexible duct. Best for users who want a larger kit with multiple accessories to reduce shopping for additional parts.

Limitation: Some installations may require trimming to fit existing configurations.
Buying Guide: Flexible Line Set Covers
What size do you need? Measure the line set diameter and select a width that matches or closely fits. Standard options include 3″ and 4″ widths, with variations in length and duct sections. Material matters for weather resistance and paintability. PVC and PP options are common; PE is quieter and corrosion-resistant in some cases. Consider paintability if you want a seamless exterior look.
What installation effort is required? Some kits include all necessary mounting hardware and simple step-by-step instructions, making DIY installation straightforward. Others may require additional tools or parts. If you’re retrofitting an existing unit, ensure the kit includes compatible connectors and elbows for a clean fit.
How durable should the cover be? Outdoor installations benefit from UV resistance and temperature tolerance. Look for lineset covers rated to handle extreme temperatures and exposure to sunlight without fading or cracking. Indoors, aesthetic matching and ease of painting can be more important than weather resistance.
What about maintenance and future access? Some designs allow easy removal of portions for maintenance or future upgrades. If you anticipate replacing lines or adding components, a modular kit with removable sections can save time and effort later.
