What You Get Back
Not a vague estimate. Not a rough count. A contractor-ready Excel spreadsheet organized by category, location, and trade — the same format you'd hand to a supplier or use in your bid.
Any PDF format works — CAD exports, scanned drawings, permit sets up to 150MB. Drag and drop or browse. We've processed 47-page commercial permit sets, multi-building residential packages, and hand-drawn TI plans.
Construction-trained AI reads your legends, schedules, notes, and drawings — understanding trade-specific symbols the way an experienced estimator would. Not generic object detection. Trade-specific symbol recognition trained on thousands of real plan sets.
Anything the AI isn't confident about gets flagged — with the exact page and location shown. You verify flagged items manually. Everything else ships in your Excel. Most contractors check flagged items in 5-10 minutes.
Download as Excel, CSV, or JSON. Import directly into PlanSwift, Accubid, or your estimating software. Or price it right there — the counts are organized exactly the way suppliers need them.

What You Get Back
Not a vague estimate. Not a rough count. A contractor-ready Excel spreadsheet organized by category, location, and trade — the same format you'd hand to a supplier or use in your bid.
-
Trade-Specific AI Trained on mechanical plans specifically. Reads ductwork schedules, equipment tables, riser diagrams, and diffuser ceiling plans — not just shapes on a page.
-
Never Misses a Duct Run AI doesn't get tired counting diffusers on page 47 of 80. Same methodology on every takeoff. No variance between estimators, no fatigue-based miscounts.
-
Catches What You'd Miss Equipment buried in equipment schedules on sheet M-7. Dampers referenced in general notes. Control devices on the electrical plans. The AI reads the whole set, not just the main duct layout sheet.

Mechanical estimators who were skeptical first. Signed up free, saw the example takeoff, then bought credits.
6 reviews
"Authentic user quotes will appear here once we collect feedback from HVAC contractors using the platform."
"We're building our testimonial library with real contractor feedback. Check back soon."
"Diffuser counts on open-ceiling retail — 312 diffusers, 3 sizes. AI had it in 18 minutes. I reviewed in 20. Done."
"Export to FastDuct works. Organized exactly how I need it — by duct size, separated by supply and return. No reformatting required."
"Signed up for a free account to see the example takeoff. Tested it on a 45-page commercial set I’d already counted. AI was within 4% on ductwork footage. Bought credits the same day."
HVAC Takeoff — Contractor Questions
Honest answers to what HVAC estimators ask before running their first takeoff.
What HVAC items does it actually count?
Ductwork (rectangular, round, oval, flex) by linear foot and size. Equipment schedules: RTUs, AHUs, FCUs, VAVs with tonnage, CFM, and model requirements. Supply, return, and exhaust diffusers and grilles by size and zone. Refrigerant piping line sets by size and length.
- Ductwork by size and type — rectangular, round, spiral, flex
- Equipment: RTUs, AHUs, FCUs, VAVs, packaged units with full schedules
How accurate is ductwork measurement?
Linear measurements are within 2-3% of manual takeoffs on scaled plans. The AI reads plan scale, converts to real dimensions, and calculates footage from drawing geometry. Non-scaled sketches or plans with missing scale references get flagged.
- Within 2-3% on properly scaled mechanical plans
- Plans without scale reference flagged automatically
Does it work on VAV and complex systems?
Yes. The AI recognizes VAV terminal units, zone controllers, and reheat coils from mechanical drawings. It reads equipment schedules specifically looking for VAV box schedules with CFM ranges and zone assignments. Complex systems flag more items — you review those manually.
- VAV boxes with CFM ranges and zone assignments
- Complex systems flag more items — you review
How long does an HVAC takeoff take?
About 15 minutes for a typical 30-page mechanical set. Larger jobs — 80-100 pages — run 25-35 minutes. Review of flagged items typically takes 15-25 minutes additional depending on system complexity. Most contractors are done in under an hour total.
- 30-page mechanical set: ~15 minutes AI analysis
- Add 15-25 minutes for flagged item review
Can I export to Accubid, ConEst, or FastDuct?
Yes — Excel (.xlsx) and CSV at any time. Organized by ductwork size, equipment type, and diffuser category. Import directly into Accubid, ConEst, or FastDuct. Or price it in the Excel — formatted with category headers the way those tools expect.
- Excel and CSV export — import into any estimating software
- Organized by category for Accubid, ConEst, FastDuct import
What if my equipment isn't in a standard schedule?
Equipment buried in general notes, referenced in spec sections, or described in abbreviation tables all get picked up. The AI reads the full set — not just the M-sheets. If equipment is described ambiguously, it gets flagged with the page reference so you know exactly where to look.
- Reads general notes, spec references, and abbreviation tables
- Ambiguous equipment flagged with page reference
