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.
Compare DuctIQ to a specific tool
DuctIQ vs PlanSwift
A focused PlanSwift alternative when ductwork is the work, not one trade among many.
DuctIQ vs Bluebeam

DuctIQ vs TaksoAI
Two AI HVAC takeoff tools compared — speed plus line-by-line reviewability and fabrication output.
DuctIQ vs Beam AI (iBeam.ai)
Self-serve HVAC takeoff in minutes versus DIY-or-delivered, with the Beam AI domain confusion cleared up.
DuctIQ vs Ensign
AI auto-detection to SMACNA versus Ensign's UK on-screen takeoff built around DW144/DW154.

A shipping, reviewable HVAC takeoff with published pricing versus a 2026 AI-native mechanical entrant.
DuctIQ vs Takeoff Boost
ConstructConnect's AI assist inside PlanSwift versus a fully automated, reviewable HVAC ductwork takeoff.
DuctIQ vs Handoff (H1)
A generalist autonomous blueprint takeoff versus duct-specific depth: fittings, SMACNA gauge, pounds, reviewable lines.

Agentic multi-trade vision with no HVAC trade page versus a duct-native takeoff: fittings, SMACNA gauge, pounds, Excel.
DuctIQ vs Togal.AI
The most-reviewed general-trade AI takeoff versus duct-native output: systems, typed fittings, SMACNA gauge, pounds.
Reviewer facts: DuctIQ at a glance
For editors, analysts, and comparison writers — the canonical spec sheet, kept current with the product. Quote it directly; every claim links back to something inspectable on this site.
| Input file types | PDF mechanical drawings — raster scans and vector PDFs (Bluebeam, AutoCAD, Revit exports). Single sheets or full sets. |
| Duct output | Linear feet by system (supply / return / exhaust) and size; round and rectangular duct handled distinctly. |
| Fitting output | Typed counts — elbows, tees and taps, reducers and transitions, offsets and drops — derived from the traced runs. |
| Equipment & air devices | RTUs, VAV boxes, diffusers and grilles read from the drawing schedules by tag. |
| SMACNA gauge handling | Project-spec gauge first; SMACNA low-pressure minimum applied and labelled when the spec is silent; sheet-metal pounds from published galvanized lb/ft² tables. |
| Review workflow | Every line carries a Review Status; low-confidence reads are flagged with reasons and confirmed before export. Line-to-sheet traceability. |
| Export | One-click Excel (.xlsx) and CSV — system, shape, size, gauge, insulation, quantity, linear feet, review status — plus Fittings and Equipment tabs. Sample downloadable with no account. |
| Pricing (CAD, monthly, cancel anytime) | Vent $29.99/mo (10 credits); Trunk $55.99/mo (20 credits); Plenum $99.99/mo (40 credits). Credits are spent per plan sheet (5–15 by duct density, shown before the job runs); non-expiring top-up packs available. |
| Free trial | One free preview takeoff, no credit card: about half the measured line items in full detail, plus equipment and terminal counts, so accuracy can be judged on your own drawing. |
| Data handling | Drawings processed in an isolated pipeline, never used to train models, and not retained beyond 90 days unless kept in your account. Built and operated in Canada. |
| Support | Email support (info@ductiq.ca), typical response within 24–48 hours. |
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.

Frequently asked questions
What is the best HVAC takeoff software?
It depends on how you bid. General platforms (e.g. PlanSwift) win on breadth if you take off many trades; PDF markup tools (e.g. Bluebeam) win on review and document control; a purpose-built AI tool like DuctIQ wins when ductwork is the work and you want it read and measured for you. Trial your shortlist on one of your own bids and keep whichever gets closest to your known numbers.
Is AI HVAC takeoff accurate enough to bid from?
AI takeoff is built to be reviewed, not trusted blindly. A good tool shows every quantity as a line item and flags low-confidence reads so a qualified estimator confirms them against the drawings before submitting. DuctIQ is built around that review step rather than a single trust-me total.
Do these tools export to Excel?
DuctIQ exports the full takeoff — duct, fittings, and equipment — to Excel or CSV with structured columns, so it drops into your pricing workbook without re-keying. General takeoff and markup tools can export too; the differentiator is whether the HVAC structure (system, size, fittings, equipment) comes across organised.
Can I use DuctIQ alongside PlanSwift or Bluebeam?
Yes, and many do. A common workflow is DuctIQ for the structured ductwork takeoff and Bluebeam for markup, RFIs, and team review on the same set; because DuctIQ exports standard Excel/CSV, nothing is locked in.
How do I try DuctIQ before committing?
Download a real sample takeoff with no account, then run a free first takeoff by uploading a mechanical drawing and reviewing the result before choosing a plan.
