HVAC Estimating
Ductwork, equipment, and controls quantities for mechanical systems — one of the most labor-intensive divisions to take off by hand.
What We Take Off
- Ductwork by size and type
- Air handling and rooftop units
- Boilers and chillers
- Building automation and controls
- Ventilation and exhaust systems
- Mechanical insulation
Works from whatever plans you have
Traditional 2D CAD drawings and PDF plan sets, or 3D BIM models — hvac quantities are taken off directly from your source files, cross-checked against the model where one exists, and delivered in the same itemized format either way.
Need the drawings themselves, not just a takeoff from them? See Drawing & Engineering Services.
Where hvac estimates commonly go wrong
Ductwork is priced by pounds of sheet metal, not just linear footage — sizing errors compound fast on a takeoff done by eye instead of off the mechanical schedule.
