How to Use the Duct2Go Duct Configurator

This guide walks through the configurator one step at a time, when to use the custom quote form instead, and the ordering mistakes that cause delays. If you already have your dimensions, go ahead and open the ductwork configurator.

Key Takeaways

• The Duct2Go configurator lets you specify standard duct online — duct type, dimensions, material, gauge, and quantity — and shows pricing as you build the order.
• Configuring an order takes minutes. Fabrication and shipping take longer, and the two should not be confused: everything Duct2Go makes is built to order rather than pulled from stock.
• Use the configurator for standard sizes. Use the custom quote form for non-standard dimensions, specialty gauges, unusual transitions, or anything you have drawings for. Custom quotes are typically returned within one business day.
• Spiral, round, and rectangular duct can all go on one order, in galvanized steel, aluminum, or stainless steel, along with the fittings sized to match.
• There is no minimum order, and you are buying directly from the fabricator rather than through a distributor.

What the Duct2Go Duct Configurator Actually Does

The configurator is an online tool for specifying made-to-order ductwork without a phone call or a quote request. You select the duct type, set the dimensions, choose the material, add the fittings you need, and see pricing as you build.

The important thing to understand is what sits behind it. Duct2Go is a fabrication shop in Chandler, Arizona, not a warehouse. Nothing you configure is picked off a shelf — the order goes to the production line and the parts are made for you.

That is why the tool asks for a specification rather than a part number. You are describing what you want built. Open the ductwork configurator and the first decision is which duct type your run needs.

Who the Configurator Is Built For

Duct2Go serves HVAC contractors, mechanical engineers, facility managers, and project owners across all 50 states, and the configurator is built for all four.

Contractors use it to order the parts on a takeoff without waiting on a supplier callback. Engineers and facility managers use it to price a scope before committing to it. Owners and shop operators use it because it does not require trade credentials to buy from.

Step 1: Choose Your Duct Type

Start by choosing spiral, round, or rectangular duct to suit the run you actually have room for. All three are available, and all three can appear on the same order.

Spiral duct is the usual specification for exposed commercial runs and anywhere leakage matters, because its machine-formed helical seam leaks less than snap-lock round duct. Round duct moves air with the least friction per unit of airflow. Rectangular duct is what fits into joist bays, tight ceiling cavities, and wall chases.

Most jobs use more than one. A rectangular trunk feeding round branches is the standard arrangement in residential and light commercial work, and you can specify both in a single pass.

Step 2: Set Dimensions to Your Drawing, Not to Stock Sizes

Set diameters, gauges, and lengths to the numbers on your drawing rather than rounding to whatever a stock catalogue happens to carry. This is the practical difference between a fabricator and a distributor.

Spiral and round duct are fabricated from 4 inches through 24 inches in standard increments, with common commercial sizes at 8, 10, 12, 14, and 16 inches. Diameters above that range are available through the custom quote process.

If your dimension is not in the configurator, that is not a dead end — it is a signal to use the custom quote form instead. Non-standard widths, heights, lengths, and diameters are core capability rather than an exception.

Step 3: Choose Your Material

Galvanized steel, stainless steel, and aluminum are all available, and all three can appear on the same order.

Galvanized steel is the standard, code-compliant choice for most residential and commercial HVAC work. Aluminum is specified where weight or corrosion exposure matters, including coastal, outdoor, and wet environments. Stainless steel covers food service, healthcare, cleanroom, and high-moisture installations.

Material affects price, lead time, and handling, so it is worth deciding deliberately rather than defaulting. If you are unsure which your project needs, our guide to galvanized, aluminum, and stainless steel ductwork works through the selection criteria, and the stainless steel collection covers where stainless is genuinely required.

Step 4: Specify the Gauge Your Project Calls For

Round and rectangular duct is fabricated from 26-gauge through 20-gauge sheet metal as standard, selected according to diameter or dimension and the application.

For rectangular duct, 26-gauge galvanized steel is standard on most residential and light commercial sizes. Larger commercial trunk lines and industrial applications are built to heavier gauges, typically 24 or 22 gauge, per SMACNA requirements.

If your project specification calls for a particular gauge, state it on the order rather than leaving it to default. Specialty gauges outside the standard range are available through the custom quote process.

Step 5: Add the Fittings Sized to the Duct You Just Specified

Add fittings, elbows, reducers, and end caps sized to the pipe you have just specified, in the same session. A duct order without its fittings is an incomplete order, and matching them afterwards is where mistakes creep in.

Everything in the HVAC duct fittings collection is built to the same standards as the duct it connects to, which is the point of ordering both from one shop. Elbows, transitions, takeoffs, reducers, couplings, and end caps all go on the same order.

Add all the parts you need to the cart and Duct2Go bundles everything together. Custom fittings that fall outside the standard catalogue can be requested by including the details in your submission.

Step 6: See Pricing as You Build

Pricing updates as you build the order, so you are never waiting on a quote to find out whether a scope fits a budget.

This matters more than it sounds. On a bid, the ability to price a duct package in real time is the difference between submitting a number you have checked and submitting one you have estimated. You can also change a variable — material, gauge, length — and watch what it does to the total.

Because you are buying directly from the fabricator, there is no distributor markup in the figure you see. That is a structural difference in how the price is built, not a promotion.

Step 7: Check Out With Shipping or Local Pickup

Orders ship flat-packed or palletized via LTL freight carrier from the Chandler, Arizona production facility, with tracking provided from the shop to your door. Both residential and commercial jobsite delivery are available.

Local pickup is available at checkout and remains the quickest option for anyone within reach of Chandler. For nationwide freight, Duct2Go palletizes and LTL-ships across all 50 states.

There is no minimum order. A single length of pipe and a full truckload are both valid orders, which is genuinely useful on a punch-list run where you need one replacement piece.

What Happens After You Place the Order

Your order goes straight to the production line. Duct2Go confirms the order, fabricates it, and ships it pre-assembled.

Standard items and custom runs carry different lead times, and the applicable one is confirmed at checkout or on your quote. Build that into your schedule rather than assuming same-week delivery — made-to-order means made, and the tradeoff for getting exactly the dimensions you asked for is that the parts do not already exist.

Configurator or Custom Quote: How to Choose

Use the configurator for standard sizes and the custom quote form for everything else. The decision usually takes a few seconds once you know the rule.

Neither route is a downgrade. The configurator is faster; the quote form handles anything the configurator’s standard ranges cannot.

What the Custom Quote Process Covers

The custom quote route handles work the configurator’s standard ranges do not reach, and quotes are typically returned within one business day.

You can upload drawings, submit dimensions, or simply describe what you need. Duct2Go fabricates from measurements, field sketches, or formal shop drawings — even a hand-written note with measurements is usable.

The published scope includes custom-size rectangular trunk lines and plenum boxes in any dimension, non-standard round diameters and lengths, specialty transitions between unusual shapes, return air boxes and air handler connections built to OEM equipment specs, flexible connectors in custom lengths, full duct system packages fabricated from PDF shop drawings or architectural plans, and replacement components for systems where standard sizes no longer exist. Submit a custom quote request with whatever documentation you have.

Get Your Sizing Right Before You Configure

Size the system before you open the configurator, because dimensions are the one input the tool cannot work out for you.

Duct sizing follows a calculation rather than a rule of thumb — ACCA Manual D for ducts within a single dwelling unit, or the ASHRAE Handbook of Fundamentals for other buildings. The calculation accounts for airflow, available static pressure, and the resistance every fitting adds to the run.

For a starting point on residential work, the Duct2Go duct calculator walks through the square-footage basics. Treat it as a first pass rather than a substitute for a full load calculation on anything complex.

Common Ordering Mistakes Worth Avoiding

• Ordering duct without its fittings. The straight sections arrive, the elbows and takeoffs do not, and the run stops at the first direction change.
• Rounding a dimension to fit the standard range instead of using the custom quote form. A quarter-inch of "close enough" becomes a field modification, and field modifications leak.
• Leaving gauge to default when the project specification names one. That is a five-second entry at order time and a rip-out at inspection.

If anything about your spec is ambiguous, talk to the shop before ordering rather than after.

Conclusion

The Duct2Go configurator exists to remove the slowest part of buying made-to-order ductwork: the back-and-forth before anyone knows what a job costs. Specify the duct, add the fittings, see the price, and place the order. Anything outside the standard ranges goes through the custom quote form and comes back within about a business day.
