- Ductworks guide covers the Roblox HVAC sandbox built around airducts, airflow, and piping systems.
- Start small: build a short straight duct route and test it before adding branches.
- Connections and direction are the two most common reasons airflow fails.
- Multiplayer servers hold up to 20 players for shared HVAC construction and experiments.
- No confirmed codes exist for Ductworks, so ignore unverified code lists.
What Is Ductworks? Game Overview
Ductworks is a Roblox sandbox experience created by Scaryneff73, centered on designing air duct systems and testing how air moves through them. The game's core tags—Airducts, Air Simulator, Air Physics, Piping, and HVAC—describe its identity: it is a building and simulation game, not a combat or progression grind. You can play it directly on the official Roblox game page.

Ductworks emphasizes relaxed sandbox building with a house-music and coffee-shop atmosphere. Don't expect quests, levels, or combat—success is measured by the duct systems you design.
The game received a Multiplayer update reflected in its current title, and the listing mentions further updates ahead. Because the experience is still young, features may shift between sessions.
Ductworks Controls and Interface
The main controls support three activities: moving around the build space, selecting and placing duct components, and testing the resulting airflow system. The bottom control bar is the central hub on every platform.
| Platform | Category | Action | Input |
|---|---|---|---|
| PC | Movement | Move around build area | Standard Roblox keyboard movement |
| PC | Inspection | Change viewpoint, check alignment | Mouse and camera controls |
| PC | Building | Select and place ducts | Bottom control bar + mouse selection |
| Mobile | Movement | Navigate the space | On-screen movement control |
| Mobile | Building | Place and adjust components | Touch input + bottom control bar |
| Mobile | Testing | Run airflow simulation | Tap the visible test control |
| All | Interaction | Switch build modes | Bottom control bar buttons |
DUCTWORKS is actively updated. Exact keybinds shown in third-party guides may be outdated—always trust the on-screen controls in your current session over older lists.
Duct Building: Step-by-Step Workflow
Effective duct building starts with a clear route, not a large amount of construction. Follow this workflow to build clean, testable systems.
Plan the Route
Decide where air begins, travels, and ends. Keep your first route short and straight so every connection is easy to inspect.
Place Main Duct Sections
Build a continuous line of ductwork using the building controls. Keep adjacent sections aligned for easy adjustment later.
Connect and Align the System
Verify that neighboring sections meet correctly and openings face the intended direction. Check each corner and transition individually.
Test Before Expanding
Run the airflow test before adding anything new. If air stops, review your most recent connection first.
Expand Gradually
Add branches one at a time, retesting after each change. This keeps the cause of any failure obvious.
Change one part of the layout at a time. Controlled modification is the fastest way to diagnose airflow problems in Ductworks.
Airflow Mechanics and Common Mistakes
Airflow depends on three things: a continuous connection, correct section direction, and sensible turns and branches. Understanding how these interact is the heart of the game's air simulator.
Connected Route
- Air follows only continuous paths
- Gaps interrupt the system
- Straight lines are the best first test
Duct Direction
- Orientation controls travel direction
- Check direction when routes look right but air stalls
- Rotate, retest, then adjust further
Branches
- Branches add paths but complicate debugging
- Add only after the main route works
- Compare single-path vs. branched results
| Problem | Likely Cause | Fix |
|---|---|---|
| Air stops mid-route | Duct sections don't meet | Realign and reconnect the gap |
| Air flows the wrong way | Section facing wrong direction | Rotate the affected section |
| Air dies at corners | Misaligned transition | Inspect both sides of the turn |
| System worked, now fails | Untested branch added | Undo or isolate the latest branch |
Use a repeatable routine: inspect the source, follow the main route, check every transition, then review branch points. When a test fails, undo the latest structural change first.
Multiplayer Builds and HVAC Experiments
Ductworks multiplayer supports up to 20 players per server, making shared HVAC construction the game's signature social mode. Good coordination prevents players from overwriting each other's sections.
Suggested cooperative roles:
| Role | Responsibility |
|---|---|
| Layout planner | Maps the main route and connection points |
| Builder | Places and connects duct sections |
| Tester | Runs airflow checks and records design differences |
Multiplayer Session Checklist:
- Join the same server and agree on the project goal
- Build a small compact test system first
- Assign planner, builder, and tester roles
- Compare a direct route vs. a turned route
- Retest after every shared structural change
Compare a single long branch against a balanced multi-branch layout between the same start and end areas. Changing one design variable at a time shows exactly which adjustment caused the result.
FAQ
Q: Is this Ductworks guide suitable for brand-new players?
Yes. This Ductworks guide starts from the basics—planning a short route, placing ducts, and testing—before moving into branches and multiplayer experiments. Complete the beginner checklist before attempting large HVAC layouts.
Q: Are there any Ductworks codes to redeem?
No officially confirmed codes exist for Ductworks as of October 2026. Avoid third-party code lists, and only redeem codes if an official in-game redemption feature or announcement appears.
Q: How many players can join a Ductworks server?
Public stats show a maximum server size of 20 players, which supports collaborative duct building and shared HVAC experiments.
Q: Why does my airflow stop even though everything looks connected?
The most common causes are a section facing the wrong direction, a misaligned corner transition, or an untested branch. Rotate the affected section, retest, and change only one variable at a time.
