- DUCTWORKS beginner guide: Start with a small, straight duct route before building complex HVAC systems.
- Core loop: Plan the route, place ducts, connect sections, test airflow, then expand one change at a time.

What Is DUCTWORKS?
DUCTWORKS is a sandbox experience on Roblox created by Scaryneff73, centered on building air duct systems and testing how air moves through them. Its core tags—Airducts, Air Simulator, Air Physics, Piping, and HVAC—describe the gameplay direction: you construct duct networks, connect them correctly, and observe the simulated airflow. Rather than combat or leveling, progression comes from your own layouts growing larger and more reliable.
The official listing also highlights house music, coffee, and a relaxed atmosphere, so treat your first sessions as low-pressure experimentation rather than a race. You can play it on Roblox on PC or mobile.
Before your first build, learn four key concepts:
| Concept | Meaning | Why It Matters |
|---|---|---|
| Airduct | A constructed passage that guides air | The basic building block of every layout |
| Airflow | Movement of air through a connected system | The result you observe and test |
| Piping | Arrangement and connection of duct sections | Determines whether air can travel at all |
| HVAC | The broader heating/ventilation system | The end goal for larger sandbox builds |
DUCTWORKS is a niche, recently launched experience (released September 2026). Public documentation is limited, so treat on-screen controls and the official game page as the source of truth when mechanics change after updates.
Beginner Build: Step-by-Step
Follow this sequence for your first working system. The goal is a small, testable route—not a sprawling HVAC network.
Explore the build area and interface
Look over the construction space and the bottom control bar. Identify the tools for placing, adjusting, connecting, and testing components before starting any large build.
Place a simple duct route
Build a short route with a clear starting point, one or more duct sections, and an ending point. Keep it straight so every connection is easy to inspect.
Connect and align the system
Check that neighboring sections meet correctly and that openings face the intended direction. Misaligned or disconnected sections are the most common reason airflow fails.
Test the airflow
Use the testing or simulation controls to confirm air travels through the route. If it fails, review the most recent connection and direction change first.
Expand gradually
Once the basic route works, add turns or branches one at a time, retesting after each change so any problem's cause stays clear.
Change one part of the layout at a time. Incremental building is the single most reliable way to diagnose why air stops moving through your system.
Airflow Mechanics and Testing
The air simulator responds to three things: whether the route is connected, the direction of each section, and how turns and branches are arranged. Understanding these makes troubleshooting predictable.
Connected Route
- Air follows only continuous paths
- Gaps or bad transitions break the route
- Start with a short straight line
Duct Direction
- Section orientation guides air travel
- Check direction when a route looks connected but fails
- Rotate, then retest before other changes
Turns and Branches
- Corners must connect on both sides
- Test each turn individually
- Add branches only after the main path works
Use a repeatable test routine whenever something breaks:
| Test Step | Action | What to Look For |
|---|---|---|
| 1 | Inspect the source | Air begins where intended |
| 2 | Follow the main route | No gaps or reversed sections |
| 3 | Check every transition | Corners align on both sides |
| 4 | Review branch points | Branches don't interrupt the main path |
| 5 | Undo the latest change | The most recent edit is the likeliest culprit |
Avoid these frequent errors: duct sections that don't fully meet, a section facing the wrong direction, unaligned corners, and adding several untested branches at once.
Controls Overview
Controls differ between PC and mobile, but all interaction runs through the bottom control bar shown in the experience. The table below summarizes what each platform can do.
| Platform | Category | Input | Purpose |
|---|---|---|---|
| PC | Movement | Standard Roblox keyboard/mouse | Reach and inspect build areas |
| PC | Camera | Mouse camera controls | Check alignment and connections |
| PC | Building | Bottom bar + mouse selection | Choose and place duct components |
| Mobile | Movement | On-screen movement control | Navigate without a keyboard |
| Mobile | Building | Touch input + bottom bar | Select, place, adjust sections |
| All | Testing | Visible control in the interface | Run and inspect airflow simulation |
| All | Troubleshooting | Placement/adjustment controls | Fix direction, spacing, gaps |
Exact keybinds beyond the bottom control bar are not officially documented. Any keyboard-specific shortcut you see online should be marked "to verify" until tested in-game.
Multiplayer Basics
The current listing is explicitly the "Multiplayer upd" version, with public stats showing a maximum server size of 20 players. Shared servers let groups build together, split testing duties, and compare designs.
Recommended cooperative roles:
| Role | Responsibility |
|---|---|
| Layout planner | Maps the main duct route and connection points |
| Builder | Places and connects the required duct sections |
| Tester | Checks airflow behavior and records results |
Good shared experiments include comparing a direct route against a turned one, testing balanced branches versus a single long branch, and rebuilding one section while another player documents the difference.
A compact group test build makes layout problems obvious before you expand. Agree on the system's purpose before anyone places ductwork.
Beginner Milestones:
- Complete one straight working duct route
- Add and test a single corner successfully
- Add one branch and compare airflow
- Join a multiplayer server and complete a shared build
- Fix a broken route using the test routine
FAQ
Q: Is DUCTWORKS free to play on Roblox?
Yes, the core experience is playable through the official Roblox game page. Optional paid items such as Creator+, Custom Appearance, and Custom Playlist have appeared publicly, but you should verify their exact effects in-game before buying.
Q: Are there any DUCTWORKS codes I can redeem?
No. There are currently no officially confirmed redeemable codes. Avoid code lists from unverified posts, since entering unofficial strings provides nothing and can mislead other players.
Q: Why does air stop moving through my duct system?
In most cases a section is disconnected, faces the wrong direction, or a corner is misaligned. Follow the test routine: inspect the source, walk the route, check transitions, and undo your most recent change first.
Q: Should I build branches right away?
No. Confirm the main path works first, then add one branch at a time. Multiple untested branches make it much harder to identify which connection changed the airflow behavior.
