The cost of installing ductwork varies between $54.55/LF and $91.47/LF. Factors affecting the price include duct material type (sheet metal vs flexible), size, insulation requirements, installation height, accessibility, number of transitions/bends needed, and local code requirements. Complex installations with multiple zones or limited access space will be on the higher end of the range.
Duct runs and supporting materials
The listed scope includes duct material and fittings, hangers, sealing materials, insulation, installation labor, and equipment rental. Confirm whether the job calls for sheet metal or flexible duct and which sizes the layout needs.
Routes change installation time
A straight, accessible run is different from a route with many bends, transitions, or tight spaces. Installation height and the number of zones also affect labor and equipment needs beyond the measured duct length.
Removal needs its own selection
Existing duct removal is an optional item. Confirm whether the job is a new installation or a replacement, and record the removal and disposal scope along with sealing, insulation, and testing.
