Supply, return, exhaust by zone and size
Refrigerant line sets measured from plan
What the AI Reads on Mechanical Plans
Construction-trained AI reads your mechanical plan legends, equipment schedules, and general notes — not just duct shapes. Commercial plans with standard SMACNA symbols and ASHRAE conventions work best.
- Duct layouts: all standard rectangular and round sizes
- Equipment schedules: reads tabular format with tonnage, CFM, model
- Ceiling plans: diffuser type, size, and location by room
What HVAC Contractors Get From Every Takeoff
Ductwork footage, equipment schedules, diffuser counts, piping — from your commercial mechanical plans.
Ductwork Footage by Size
Rectangular, round, and oval ductwork counted by linear foot — separated by size (6" through 48") and gauge (26 ga, 24 ga). Supply, return, and exhaust duct counted separately with fittings by type.
- Rectangular duct by size and gauge (26 ga, 24 ga)
- Round and spiral duct by diameter
- Fittings: elbows, tees, reducers — by type and size
Equipment Schedules
RTUs, AHUs, FCUs, and VAV boxes extracted with tonnage, CFM, and location tags — organized the way your supplier expects for ordering.
- RTUs: tonnage, CFM, electrical requirements
- AHUs and FCUs: airflow, static pressure, coil type
- VAV boxes: max/min CFM, zone assignments, reheat coils
Diffuser & Grille Counts
Supply diffusers, return grilles, and exhaust grilles counted by size and type — 2x2, 2x4, round, linear bar. Organized by floor and zone for installation phasing.
- Supply diffusers: 2x2, 2x4, round, linear — by size
- Return and transfer grilles by size and type
- Exhaust grilles and toilet room exhaust separated

HVAC Contractors Who Use It on Real Jobs
Mechanical estimators who were skeptical first. Signed up free, saw the example takeoff, then bought credits.
"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
