Quality Duct Supply is a ductwork fabrication company serving mechanical HVAC contractors throughout Michigan and the surrounding states. QDS prides itself on knowing what it takes to fabricate a job and offers a number for the entire project, built to specs, before our customers have to put their bid in for it. In turn this helps the mechanical HVAC contractors that we serve peace of mind and allows them to concentrate on the installation aspect of any given project. With our BIM/CAD 3-D modeling capabilities we can draw any project, coordinate or facilitate the meetings and supply our customers with installation and fabrication drawings for their project.
