Ductly reads your shop's drawings — custom fab pieces, stock items, install hardware, accessories — and emits priced line items into your ERP. Missing a gauge the contractor forgot to mark? A spec the drawing didn't show? Ductly flags it — instead of inventing one.
Talk to the founder, not a chatbot.
| Family | Spec | Gauge | Material | Qty |
|---|---|---|---|---|
| Duct | 24" × 12" · 60 LF | 26 | GLV | 12 |
| Round Elbow | 14"Ø · 90° · ⚠ confirm radius | 24 | GLV | 4 |
| Reducer | 24×12 → 18×10 · 18"L | 26 | GLV | 2 |
| Plenum Take Off | 12" × 8" · 14"L | 26 | GLV | 6 |
Line 2: drawing didn't spec a centerline radius on the elbow — 1D or 1.5D? Ductly flagged it for your estimator instead of defaulting.
Most AI quoting tools market accuracy percentages they can't reproduce on your drawings. We trade theatre for honesty. Day one, we read what's clear and flag what isn't — your estimator confirms a handful, not a hundred. Every drawing your shop quotes compounds the engine forward. Today's 90% is next quarter's 95, and the quarter after's 99.
Ductly extracts every line it can read confidently and tags every line it can't. Your estimator handles the flagged handful instead of measuring the whole sheet from scratch.
Every drawing your shop quotes refines the engine. Per-customer conventions surface. SMACNA defaults adjust to your shop's overrides. Accuracy climbs fast.
High-confidence extraction on your shop's drawings. Quote turnaround minutes, not hours. Your estimator approves and ships — the system keeps tuning quietly underneath.
Zero invented dimensions throughout. Empty when unknown, always — that's the discipline.
Your senior estimator spends three to five hours measuring lines on a drawing your shop has quoted a hundred times before. By the time the quote ships, the GM has already called two faster bidders.
Lines measured one by one. Fittings counted. Pricebook looked up by hand. Every quote eats an afternoon.
Owners now expect quotes the same day. The shop that takes three days doesn't get the callback. Speed is the new bid.
Adding another senior estimator costs a salary you can't recover until year two — and they still take five hours per drawing.
Contractor emails a drawing to your quote inbox? Auto-extracted. Walks into the counter with a paper plan? Scan it — phone, printer, whatever's at the counter. Drag-and-drop at your desk? Same pipeline.
Custom fab geometry. Stock items matched to your part numbers. Install hardware — cleats, hangers, threaded rod, flange corners — recognized and priced. Cover-page defaults applied across the sheet.
Most quoting tools make you adopt their pricebook. Ductly adopts yours. We reverse-engineer your existing ERP and push priced line items in directly. Your workflow stays your workflow.
Reading custom-fab drawings end-to-end is hard engineering work — 52 fitting families with industry-standard slot definitions, cover-page gauge tables parsed and applied across multi-page sets, stock items matched against your part numbers, callouts and hand-marked dims read at human-foreman accuracy. We built all of that.
The move that defines the engine is what happens next: when a spec is missing — the contractor forgot to mark a gauge, a callout is smudged, a corner is torn — generalist AI invents a number to fill the gap and look fast. Your foreman catches the bad spec in the field, the fitting doesn't seam, trust is gone. Ductly stops, flags it, asks your estimator. And when the drawing came in by email, Ductly drafts the clarification reply to the contractor automatically — sent in the same minute your estimator approves, not after the next call-back. Four questions instead of four hundred.
Every line traceable to the drawing. Or flagged. Never invented.
| Family | Spec | Gauge | Material |
|---|---|---|---|
| Reducer | 24×12 → 18×10 · 18"L | 26 | GLV |
Transition length wasn't marked on the drawing. Tool guessed 18". Off by 6 — reducer doesn't seam between the duct runs in the field.
| Family | Spec | Gauge | Material |
|---|---|---|---|
| Reducer | 24×12 → 18×10 · ⚠ confirm length | 26 | GLV |
Transition length wasn't marked. Ductly stopped, flagged it, asked your estimator. Quote ships defensible.
Other AI quoting tools read equipment schedules, site plans, or generic construction takeoffs. Ductly is built around the geometry, callouts, and conventions of HVAC drawings specifically — custom fab pieces, distributor stock items, install hardware, the lot. Whatever your shop quotes from, every day.
52 fitting families with industry-standard slot definitions. Duct sizes, elbow angles, reducer transitions, plenum take-offs, dampers, flex connectors — all read directly from the drawing.
Gauge tables on the cover sheet, callouts on the plan, itemized stock lists in the corner — Ductly reads all of them and applies the defaults to the right fittings.
SMACNA defaults out of the box. Your shop's overrides on top. Your customers' quirks baked in over time. Quotes ship in your part numbers, your gauges, your contractor-specific rules.
Ductly ships with the industry-standard SMACNA construction tables baked in — gauges, joint specs, hanger requirements — the same defaults your foreman knows by heart. Every quote your estimator approves teaches the engine your shop's actual conventions.
By month six, Ductly is quoting like your senior estimator. Not like any other shop's senior estimator.
HVAC Duct Construction Standards baked in: pressure-class gauge tables, longitudinal seam minimums, transverse joint specs, hanger gauge/spacing rules. Every quote starts from the same baseline your shop foreman would.
Every contractor you quote for has conventions your estimator already knows. Ductly picks them up from your edits — quietly, per-shop — and applies them automatically the next time that contractor's drawings land.
When your estimator overrides a value, Ductly logs the pattern. Repeat overrides surface as candidate rules for your shop. Approve the rule once; it applies forever.
Your drawings help our engine learn HVAC faster — that's how we go from week one to dialed-in on your shop's work. Your customers, rates, quotes, and pricebook? Those never cross tenants. The pilot contract spells the deal out plainly: what we use, what we don't, what stays yours.
Get a 30-minute call with the founder. Bring a drawing from your shop — we'll show you what Ductly reads, what it flags, and what dialing the engine into your shop looks like. If it's a fit, you're one of the first five.
