Ductwork

AI takeoff for ductwork estimators.

Duct runs measured by size. Branches, dampers, diffusers, and terminals counted automatically. The flat photocopy of an HVAC plan that broke your last tool — bring that one to the demo.

What the model reads

Ductwork as it appears on real drawings.

Ductwork drawings usually live alongside ceiling plans, fire strategies, and other services. Symbol-matching tools want clean isolated ducts; real plans have ducts overlaid with diffusers, sprinklers, and lighting.

ZeroCount measures duct runs by size — rectangular and circular — and counts the fittings that drive cost: dampers, diffusers, grilles, transitions, and bends.

What it counts

Lengths by size, fittings by type.

Duct lengths by size

Rectangular and circular. Lengths broken down by section size — straight to your rate sheet.

Diffusers, grilles, terminal devices

VAV boxes, ceiling diffusers, return grilles. Counted by type and size.

Damper counts

Volume control, fire, smoke. Identified by symbol and counted with their location reference.

Branches, bends, transitions

Counted with their angle and size — fittings drive a real chunk of the cost on a ductwork bid.

Common questions

Quick answers.

Do you handle scanned PDFs and photographed plans?
Yes. Vector PDFs, scanned PDFs, and photos of plans on a desk all run through the same engine. Most of the value is in the messier formats — a clean CAD-export PDF is the easy case.
How does pricing work?
£55 per licence per month. No tiers, no enterprise upsell. Multi-licence rates available from five seats — bring the team size to the demo call.
Can I push counts into my estimating system?
Counts push directly into Ensign estimating with 300,000+ live UK prices and labour times. Excel export is also supported if you price elsewhere.
