DuctIQ vs Legacy PDF Markup & General Takeoff Tools
Most HVAC estimators take off ductwork one of three ways today: marking up a PDF with a general review tool, clicking every run in a general multi-trade takeoff package, or keying it into a spreadsheet. DuctIQ is a fourth option — purpose-built AI HVAC takeoff that reads the mechanical drawing, measures the duct, and hands back a reviewable, Excel-ready list.
This is a fair, category-level comparison. General tools are capable and broad; DuctIQ is deliberately narrow. The table below shows where each category fits so you can decide honestly.

Capability comparison by tool category
| Capability | General PDF markup | General takeoff | DuctIQ (AI HVAC takeoff) |
|---|---|---|---|
| Measure quantities off a PDF | Yes | Yes | Yes |
| Built specifically for HVAC / ductwork | — | — | Yes |
| AI reads the drawing and measures duct for you General tools give you a measure tool; you still trace every run by hand. | — | — | Yes |
| Supply / return / exhaust separated by size automatically | — | — | Yes |
| Fittings counted & equipment pulled from schedules | — | — | Yes |
| Excel / CSV export | Yes | Yes | Yes |
| Line-by-line review with low-confidence items flagged | — | — | Yes |
| SMACNA-aware fabrication / shop-drawing output | — | — | Yes |
| Take off all trades (concrete, framing, finishes…) If you bid many trades in one tool, a general platform's breadth is a real strength. | — | Yes | — |
Comparison is by tool category, not a knock on any product. Bluebeam and PlanSwift are capable, widely used tools; this table is about where a purpose-built HVAC takeoff fits.

When a general tool is the better call
If you bid many trades from the same set — earthwork, concrete, framing, finishes, and mechanical — a general takeoff platform that measures all of them in one place is a real strength, and the switching cost for the duct portion alone may not be worth it. If your team already lives in Bluebeam for markup and document control across a project, that workflow has genuine value beyond takeoff.
When DuctIQ is the better call
DuctIQ makes sense when ductwork is the work. Instead of tracing every run by hand, you upload the mechanical PDF and get supply, return, and exhaust measured and grouped by size, fittings counted, equipment pulled from the schedules, and every line shown for review with low-confidence items flagged. It exports clean Excel and CSV, so the numbers drop straight into the bid sheet you already use — and it carries through to SMACNA-aware shop drawings for fabrication.
