For years I have looked to find a product that can easily and cost effectively hide the refrigerant line sets of a wall mounted split system. I found a company that distributes the SlimDuct Line Set Ducting System. It seems like such an easy fix, but it has been very difficult to find products like these.

With all of the wiring, condensation tube and line sets coming through the exterior of the wall, the SlimDuct Ducting System seems the best way to maintain the ascetic appeal of your home. SlimDuct products encase the unsightly items for added UV resistance, fire resistance, abnormal weather and hungry living critters.

Standard colors include ivory, white and brown but I went all out and painted my line set covers the same color as my house. The basic pieces needed to finish off my mini split installation were a 78” length SlimDuct cover, a 90° wall inlet and a 90° end outlet. Not bad.

SlimDuct also offers 45° fittings, couplers for joining two or more of the 78” straight lengths and a variety of other pieces to get around windows and corners of your home.

There are three different dimensions of piping that can be ordered from SlimDuct.

1. SD-77: 3” x 2 ½”
2. SD-100: 4” x 2 ¾”
3. SD-140: 5 ½” x 3”

When I spoke to SlimDuct they told me that the SD-77 was sufficient for a standard mini split installation that uses a 3/8” x 5/8” line set, ¾” drain hose and 14 gauge wiring.

They were right. The SlimDuct components were easy to cut to size and now look great on the exterior of my home.
