HVAC Estimating

Accurate ductwork weight calculations, register counts, and mechanical equipment takeoffs (RTUs, chillers, split systems).

Trade Overview & Cost Estimating Methodology

HVAC systems are highly specialized and capital intensive. We calculate ductwork surface areas and sheet metal weights (galvanized, stainless, aluminum), count dampers, diffusers, registers, and schedule central air handlers, condensers, RTUs, and VRF systems.

Our HVAC Takeoff Parameters

We extract and itemize every relevant component on the blueprints, ensuring zero gaps in your bid proposal.

Sheet metal ductwork area and weight modeling (low/medium/high pressure lines)
Spiral, rectangular, and flexible duct runs with hangers and insulation
Mechanical equipment (RTUs, split systems, VRF, chillers, cooling towers, boilers)
Air distribution devices (registers, grilles, diffusers, fire dampers, sound attenuators)
Refrigerant piping, condensate lines, control wiring, and thermostats
