State of the art HVAC Estimating Software and Modeling

21st Century Duct Design

You want your order of HVAC ductwork to arrive ready to go, not as a collection of jigsaw pieces that takes time to sort and may include an ill-fitting piece or two.

At Hranec S.M.I., our design teams have you covered. Manual take offs with paper and drafting boards are a thing of the past, and with them the old scourges of imprecision and drafting errors.

Using state-of-the-art HVAC Estimating software and 3D Modeling, Hranec assures that each piece of ductwork is precision fit to its space, connections, and supports.
Optional install drawings provide your field crews with the convenience of numbered pieces, which can be pulled and fit together with the ease of a numbered puzzle.
Technology that saves you money. The labor intensive, time-consuming work of manual duct take-offs is eliminated, while precision increases. With Hranec’s state-of-the-art HVAC duct design, data is fed directly from CAD to the coil line and plasma tables.
