An Everwell line set cover is a decorative, protective enclosure used primarily in HVAC (mini-split or ducted split) installations. Its purpose is to conceal and protect exposed refrigerant piping, electrical wiring, and condensate/drain lines from the elements, while giving the installation a cleaner, more finished aesthetic. The cover is made of durable plastic materials that are weather-resistant and UV-stabilized, and typically comes as a modular kit including straight sections and fittings (elbows, joints, end caps, etc.). The cover pieces snap together over existing lines (or can be installed before lines) and may be paintable to match the surrounding wall.
