A Line Set Cover is a decorative and protective PVC housing used to hide the copper pipes and wires on the exterior of your home. Without a cover, the white insulation on your Installation Kit can degrade from UV exposure or be damaged by animals. We offer the 12ft PVC Decorative Line Set Cover Kit which can be painted to match your siding perfectly. These kits include various elbows and wall inlets to ensure a clean, professional-looking installation for your Single-Zone system. Using a cover kit is the best way to ensure the longevity of your Refrigerant Lines. It also prevents pests from entering the small hole where the lines pass through the wall. You can find more installation accessories in our Parts collection. It is the finishing touch that transforms a DIY project into a Professional Grade setup.
