Comparison Table
Carrier HAP
enterpriseCarrier HAP performs HVAC load, system, energy, and air-distribution calculations for building projects.
HAP’s psychrometrics-driven coil and HVAC system simulation ties humidity and performance impacts directly to sizing assumptions.
Carrier HAP calculates HVAC airside and heat transfer performance from building and equipment inputs, then produces psychrometric and energy-linked results for ducted system design. It provides a library-driven workflow for component selection and system simulation that supports iterative sizing based on load, humidity, and airflow targets.
Ducting workflows connect through duct-related data and distribution assumptions rather than offering a dedicated duct fabrication drawing pipeline. HAP fits teams that need repeatable calculations and documentation outputs more than they need end-to-end sheet metal detailing.
- +Strong HVAC load and coil performance simulation with detailed psychrometrics
- +Repeatable system runs support iterative airside sizing checks
- +Document outputs help standardize calculation packages for reviews
- +Works well when duct behavior is handled through distribution inputs
- –Limited ductwork fabrication support compared with CAD-first ducting tools
- –Airflow balancing results depend on modeling assumptions rather than auto distribution

Best for: Fits when projects need HVAC airside calculations and documentation repeatability without duct fabrication drawings.
Wrightsoft Right-Suite Universal
vertical specialistRight-Suite Universal supports residential HVAC load calculations, equipment selection, and duct system design.
Duct calculations tied directly to the CAD layout workflow for repeatable drawings and schedules.
Wrightsoft Right-Suite Universal targets HVAC duct design workflows with CAD drafting support and duct calculations tied to project data. It combines duct sizing and layout output so designers can carry constraints like duct fitting assumptions into fabrication-style deliverables.
The Universal edition emphasizes integration with common CAD exchange formats and recurring project configuration so teams reuse standards across jobs. Documentation and output control matter most when projects require consistent drawings and schedules from one design intent.
- +CAD-centric duct layout workflow with calculation-linked outputs
- +Reusable job configuration helps maintain standards across projects
- +Export-focused interoperability for sending drawings and schedules downstream
- +Supports both rectangular and round duct planning in one workflow
- –Automation depends on how consistently projects are configured up front
- –API-driven extensibility is limited compared with automation-first duct tools
- –Change propagation across complex assemblies can feel manual
- –BIM authoring and clash workflows rely on external CAD processes

Best for: Fits when HVAC duct designers need consistent CAD drawings plus calculation-linked schedules for fabrication handoff.
Autodesk Revit
enterpriseBIM software for modeling, documenting, and coordinating HVAC duct systems.
Revit’s API enables HVAC-specific automation for routing rules, parameter validation, and schedule generation.
Revit’s ducting workflow centers on parametric HVAC elements inside a model that drives 2D drafting views, section cuts, and schedules. It supports clash detection with other building disciplines by relying on model-based geometry rather than exported drawings, which keeps coordination tied to the same dataset. Connectivity and system classification in Revit help maintain consistent layouts when duct paths change and when equipment and spaces are edited.
A key tradeoff is that Revit does not include an HVAC design engine for duct sizing and friction loss calculations as a native, turn-key step in the duct model. Teams typically pair Revit with external duct design or calculation tools, then import results or manually apply sizing to duct parameters. Revit fits best when coordination, documentation, and model-driven fabrication drawing generation matter more than calculation-centric duct sizing.
- +Model-based coordination keeps duct changes consistent across 2D and 3D
- +Revit API enables custom HVAC content, automation, and validation add-ins
- +Schedules and views reduce manual rework during routing edits
- +IFC and DWG/DXF exchange support cross-tool documentation workflows
- –Native duct sizing and airflow balancing logic is not a built-in design solver
- –Effective governance depends on template discipline, naming rules, and shared parameter setup

vertical specialistMagiCAD designs, sizes, documents, and coordinates HVAC duct systems in BIM and CAD workflows.
Model-to-document synchronization that updates duct sizing and annotations after geometry edits.
MagiCAD’s core workflow starts from an architectural or MEP context and then drives duct layout, sizing, and component selection from that geometry.

Documentation output supports downstream drawing and fabrication needs by generating consistent annotations tied to the modeled ductwork.
- +Tight linkage between duct layout edits and sizing results
- +BIM-oriented output keeps duct documentation aligned to model geometry
- +DWG and DXF import and export supports CAD handoff
- +Calculation-driven component selection reduces manual reconciliation

How to Choose the Right Ducting Software
We focus on what changes outcomes in ducting software: whether your workflow stays consistent from duct sizing through airflow balancing, and whether exports/imports match how your team shares plans. The key separators are the integration depth around your CAD/BIM pipeline and the control depth over project data.
Calculation transparency
Why it matters
Calculation transparency matters because ducting software users need to reconcile duct sizing and friction loss assumptions with the outputs they get. When the steps are visible, we can trust edits and explain differences during reviews.
How to check
Load a sample project and inspect a report tied to airflow and pressure results. Look for editable parameters (including friction loss inputs) and a per-duct breakdown that matches what the UI shows.
Import/export file workflow
Why it matters
Import/export file workflow matters when we move duct layouts between design and review stages. If DXF/DWG or schedule exports are incomplete, rework grows and version history breaks.
How to check
Ask for a demo that imports a provided geometry/draft file and then exports a drawing or schedule. Verify which entity types survive (duct segments, fittings, annotations) and whether units and layers stay consistent.
Automation rules for duct runs
Why it matters
Automation rules for duct runs matter because repeated layouts often follow common rules for supply and return ductwork routing. When the rules are configurable, we avoid manual retyping and reduce inconsistent results.
How to check
In the demo, set up a small ruleset for routing or sizing targets, then generate duct runs for multiple zones. Confirm the system reuses the rules on re-run and highlights what it changed.
Project data model consistency
Why it matters
Project data model consistency matters because ducting software must keep relationships stable between segments, fittings, and schedules. If objects drift between edits, airflow balancing outputs won’t reconcile with the drawing.
How to check
Make an edit that changes one duct segment length or a fitting choice, then re-run calculations. Check whether the corresponding schedule lines and balancing results update without creating duplicate objects.
Drawing and schedule output quality
Why it matters
Drawing and schedule output quality matters because teams review decisions through diffuser and grille selection and supporting documentation. Better outputs reduce the gap between what we calculated and what stakeholders can verify.
How to check
Export both a drawing view and at least one schedule from the same project. Confirm you can filter, group, and label outputs so each duct run and its key assumptions appear in a review-friendly format.
Red flags
- Outputs change but the underlying calculation steps are hidden.
- Import/export drops duct entities or scrambles units/layers.
- Edits duplicate objects and schedules no longer match drawings.
Fit by situation
- If our team needs to justify results during design reviews, prioritize Calculation transparency.
- If we frequently pass duct layouts between CAD/BIM and reporting, prioritize Import/export file workflow.
- If we build many similar zones with repeatable routing patterns, prioritize Automation rules for duct runs.
