Air Duct Design & Layout Services
CAD-Ready Ductwork Layouts That Perform in the Real World
At Elements Design Group, our air duct design services are built for contractors who want more than just lines on paper. We deliver engineered duct layout designs that align with Manual J, N, D, or Q calculations—balancing airflow, minimizing friction loss, and ensuring your HVAC system performs as designed.
Whether you’re building a single-family home or a multi-zone commercial system, we’ll create air duct layouts that are easy to install, code-compliant, and ready for review.
More Than a Diagram — A Full System Strategy
Our designs aren’t just visual — they’re functional tools that installers and inspectors can rely on. Every layout we produce is built on verified load data, and engineered to reflect system type, duct material, velocity limits, and equipment placement.
We factor in:
- Supply and return balance
- Duct sizing based on friction loss
- Equipment compatibility
- Zoning and airflow priorities
- Local code and climate considerations
This isn’t a template — it’s tailored mechanical planning you can build from.

What’s Included in Our Air Duct Design Service
- Professionally drafted ductwork layout drawings (PDF + CAD available)
- Supply and return duct routing by zone
- CFM per room/area labeled for installers
- Duct sizing based on calculated loads & static pressure
- Duct material, fittings, and system type reflected in the design
- Compatible with Manual D (residential) and Manual Q (commercial)
- Includes up to 2 rounds of revisions
You send the floor plan—we handle the engineering, airflow math, and layout clarity.
Who This Is For
- HVAC contractors installing residential or commercial systems
- Builders needing MEP coordination drawings
- Architects needing engineered HVAC schematics
- Permit submittals where full duct drawings are required
- Homeowners working with installers or consultants
Whether it’s flex, rigid, sheet metal, or a hybrid system, we’ll design a layout that’s clean, balanced, and tailored to your job site.

Frequently Asked Questions
The most common formula used in duct design is based on airflow (CFM), friction rate, and velocity:
Duct Diameter = √(CFM ÷ Velocity) × 13.5 (for round ducts)
In reality, professional designs account for total equivalent length, fittings, static pressure, and duct material—handled automatically in our software tools.
We use these formulas behind the scenes to size your ducts based on your project’s Manual J/N report.
Some general guidelines include:
- Keep duct runs as short and straight as possible
- Minimize sharp turns and flexible duct kinks
- Balance supply and return airflow
- Avoid oversizing ducts (which reduces velocity and performance)
Our duct layout designs follow ACCA Manual D or Q standards, depending on the project type.
A common rule of thumb is 1 CFM per square foot of conditioned space, but this is only a rough starting point. Real duct design requires room-by-room airflow calculations and friction rate analysis.
That’s why we don’t rely on rules of thumb—we use verified data from Manual J or N, tailored to your layout.
