The Line Set Covers & Wall Sleeves category focuses on the finishing details that protect and hide refrigerant piping, control wiring and condensate drains as they travel between indoor and outdoor units. A clean, sealed penetration not only looks better on the home or building façade—it also helps protect insulation, reduce UV damage and keep pests, wind-driven rain and debris out of the wall assembly.
Here you’ll find rigid line set cover systems, elbows, couplings, flat and vertical sections, end caps, wall inlet fittings, wall sleeves and trim plates sized for single and bundled line sets. These accessories are commonly used on ductless mini-splits, heat pumps, VRF branches and retrofit central systems where the line set is surface-mounted on siding, stucco, brick or interior walls. UV-resistant materials and color options help the installation blend into the exterior and stay stable under sun exposure.
When selecting line set covers and wall sleeves, confirm the total outside diameter of insulated lines, control cable and drain tubing to ensure the channel size is adequate. Also consider wall construction, siding type, color matching, fastener style, and local code or HOA appearance requirements. Properly sized sleeves and covers make future service easier and reduce the chance of damaged insulation or crushed tubing during building maintenance.
Pro tip: For multi-zone and future-ready installs, oversize the cover channel or use modular sections so you can pull in additional line sets or control wiring later without cutting a new penetration through the wall.
