A Wendes Alternative for Fast, Browser-Based HVAC Takeoff
Wendes Systems has been a serious name in mechanical estimating for decades. Its software covers HVAC, plumbing and ductwork (WenDuct), with labor and material databases that mechanical contractors have priced jobs from for a long time. In 2026 Wendes integrated Takso AI takeoff into its 64-bit estimating platform, so symbols, ductwork and piping can be recognized on the PDF and fed into a Wendes estimate. For a shop already standardized on Wendes, that is a meaningful upgrade.
This page is for the estimator weighing the other path: a takeoff that lives in the browser, needs no installation or ecosystem, and hands back the duct quantities as an Excel workbook you price in however you like. DuctIQ reads the mechanical PDF and returns duct linear feet by system and size, fittings counted by type, air devices, equipment, SMACNA-aware gauge and pounds, every line reviewable before export. Below is the honest comparison.

What Wendes does well
Wendes is a complete estimating system rather than a takeoff tool. The takeoff flows into labor units, material pricing, fabrication and bid summaries inside one environment, and the databases behind it reflect years of mechanical contracting practice. Contractors who run their entire estimating department on Wendes get consistency: every estimator prices the same way, from the same data, with the same reports.
The Takso integration adds AI plan reading to that environment. If your workflow already ends in a Wendes estimate, AI takeoff that lands inside it is the shortest path and deserves a serious look. Verify the current feature set, pricing and platform requirements directly with Wendes, because the integration is new and moving.
A legacy suite vs a cloud-native takeoff
The trade-off is weight. A full estimating suite asks you to install software, license seats, adopt its databases and send your takeoff through its ecosystem to get value from it. That is the right investment for some shops and a heavy one for others: a smaller mechanical contractor, a sheet metal shop pricing only its own scope, or an estimator on a Mac who does not want a Windows machine just for takeoff.
DuctIQ is deliberately light. It runs in any modern browser on Mac or Windows, there is nothing to install, and your first takeoff is free with no credit card. Upload a mechanical PDF, review the lines the AI flags, and export a structured Excel or CSV file. Nothing about your pricing lives inside DuctIQ, so there is no ecosystem to leave if you change how you estimate.
Side by side on the duct takeoff
Score both on the takeoff itself. Where a detail is not in public materials, the honest cell says what to verify in a demo:
| Capability | Wendes with Takso AI (verify in a demo) | DuctIQ (verifiable today) |
|---|---|---|
| Where it runs | Installed 64-bit estimating software; ask about Mac and browser access | Any modern browser on Mac or Windows, nothing to install |
| Getting started | Ask about licensing, onboarding and database setup | Upload a PDF; first takeoff free, no credit card |
| AI duct takeoff | Takso AI recognizes symbols, ductwork and piping | Duct LF by system and size, typed fittings, air devices, equipment |
| Gauge and weight | Ask how gauge and pounds are resolved per run | Spec-first gauge, SMACNA minimum labelled; pounds from published lb/ft² tables |
| Pricing and labor | Full labor and material databases, its core strength | Not included: DuctIQ exports quantities for your own pricing |
| Output | A Wendes estimate | Structured Excel/CSV, sample downloadable below |
Fair under uncertainty: Wendes' estimating depth is credited; cells we cannot verify say what to ask.
Speed where the hours actually go
On most mechanical bids the takeoff, not the pricing, eats the week. DuctIQ attacks that step directly: the engine reads the sheets at scale, traces duct runs, separates supply, return and exhaust, derives fittings from the geometry, counts air devices on the plans and resolves their tags against the schedules. Your job moves from clicking every run to auditing a finished list, with low-confidence reads flagged and grouped first.
Direct to Excel, no lock-in
The deliverable is a workbook: duct by system, size and gauge with linear feet, fittings by type, diffusers and grilles, equipment and sheet-metal weights, each on its own sheet. Drop it into the pricing spreadsheet you already trust, or import it into the estimating system you already own. Judge the file before creating an account:

Settle it on one real bid
Take a mechanical set you have already priced. Ask Wendes to demo the Takso takeoff on it, and upload the same PDF to DuctIQ. Compare duct footage by system, fitting counts and air-device counts against numbers you already trust, and note how long each took from opening the file to a usable quantity list. Keep whichever process survives your audit.

Frequently asked questions
What is Wendes?
Wendes Systems makes mechanical estimating software for HVAC, plumbing and ductwork contractors (including WenDuct), with long-standing labor and material databases. In 2026 it integrated Takso AI takeoff into its 64-bit estimating platform. Verify current capabilities and pricing on wendes.com.
Is DuctIQ a replacement for Wendes?
Not for everything. Wendes is a full estimating system with pricing and labor databases; DuctIQ is an AI duct takeoff that exports quantities to Excel. Shops that want a lighter, browser-based takeoff and price in their own spreadsheets can use DuctIQ instead; shops standardized on Wendes can use DuctIQ beside it and import the quantities.
Does DuctIQ run on a Mac?
Yes. DuctIQ runs in any modern browser, including Safari and Chrome on macOS, with nothing to install. Ask Wendes directly about Mac or browser access for its software.
How does DuctIQ compare with Takso AI inside Wendes?
Both read mechanical PDFs with AI. The difference is the destination: Takso inside Wendes feeds a Wendes estimate, while DuctIQ returns a reviewable duct takeoff (systems, sizes, typed fittings, air devices, SMACNA gauge, pounds) as a standalone Excel/CSV file. Our separate TaksoAI comparison covers the AI side in more detail.
What does DuctIQ cost?
Pricing is published: monthly plans from $29.99 CAD with per-sheet credits shown before each job runs, non-expiring top-up packs, cancel anytime, and a free preview takeoff with no credit card.
