CSI 23 — HVAC

HVAC & Ductwork Estimating

Mechanical estimating — equipment, ductwork, and piping by size and CFM.

HVAC estimating combines equipment, ductwork, and piping — each with its own pricing and labor. We quantify mechanical systems by size and type, from RTUs and AHUs to duct runs and refrigerant piping.

What’s Included

Quantified to the drawing.

  • Ductwork by size, length, and material (LF/SF)
  • Equipment: RTUs, AHUs, fans, pumps
  • Refrigerant, chilled, and hot water piping
  • Grilles, registers, and diffusers
  • Insulation and accessories

Deliverables

Bid-ready in Excel.

  • HVAC takeoff by system
  • Material and equipment pricing
  • Labor hours by mechanical activity
  • Bid-ready Excel deliverable

How It Works

From plans to bid in 48 hours.

01

Send your plans

Upload PDF, DWG, DXF, or image plans through the quote form or chat. Tell us your trade, deadline, and deliverable.

02

We take off & price

Our estimators quantify every component and price at current U.S. market rates, with labor hours by activity.

03

Bid-ready delivery

You receive a line-item Excel takeoff and cost estimate within 48 hours — ready to price your bid and submit.

Do you include HVAC equipment and ductwork together?

Yes — equipment (RTUs, AHUs, fans, pumps) and ductwork are quantified and priced together for a complete mechanical bid.

Can you price refrigerant and hydronic piping?

Yes. Refrigerant, chilled water, and hot water piping are quantified by size and length alongside the ductwork and equipment.
