Description
Need to disconnect and cap duct trunk lines from a rootop HVAC unit on a 1 story commercial building. The unit is toast and the duct is dripping into the space below because the inside insulation is getting wet and saturated from another area of the line. Trunk lines are mainly 12" square. There are six of those. There are two 6 or 8" round lines that also go into the space. ducting can be cut above the rain collar or whatever it's called. Everything else can stay in place. it will be removed by others.
