- Ductworks Project 5 refers to the latest Multiplayer update of the Roblox HVAC sandbox DUCTWORKS.
- Core loop: plan a duct route, place sections, connect, then test airflow before expanding.
- Multiplayer: servers hold up to 20 players; use divided roles for shared builds.
- Air physics: direction and connection quality determine how air travels through your system.
- No confirmed codes exist for this experience; avoid unverified code lists.
What Is Ductworks Project 5?
Ductworks Project 5 is the community nickname for the current Multiplayer-focused phase of DUCTWORKS, the Roblox air-duct and HVAC sandbox created by Scaryneff73. The game page is currently listed as "DUCTWORKS / Multiplayer upd," and its core tags — Airducts, Air Simulator, Air Physics, Piping, and HVAC — describe a building experience where players design duct networks and observe how air moves through them.
Unlike progression-driven Roblox games, Ductworks is a sandbox simulation: there are no units to roll, no combat, and no confirmed upgrade path. The appeal is in construction, airflow experimentation, and shared building with friends. The game description also highlights House music, coffee, and a bottom control bar, giving sessions a relaxed, creative atmosphere.
If you arrive expecting combat, pets, or code redemptions, you will be disappointed. Ductworks rewards patient builders who enjoy testing layouts one change at a time.

Core Mechanics: Airflow and HVAC Simulation
Airflow in Ductworks depends on three factors: whether the route is continuously connected, whether each duct section faces the correct direction, and how turns and branches are arranged. Air follows the network you build, so every placement decision is a physics decision.
| Mechanic | What It Does | Common Failure |
|---|---|---|
| Connected route | Forms a continuous path air can follow | Gaps or missing transitions interrupt flow |
| Duct direction | Sets orientation each section pushes air | Reversed sections stop or misroute air |
| Turns and transitions | Change route direction cleanly | Misaligned corners break continuity |
| Branches | Split one system into multiple paths | Untested branches hide the source of problems |
| Testing controls | Verify the simulation result | Skipping tests makes errors compound |
Build Small First
- Straight line test route
- Every connection visible
- Easiest to debug
Test Before Expanding
- Run simulation after each change
- Undo the latest edit on failure
- One variable at a time
Branch Last
- Confirm the main path works
- Add one branch, then retest
- Keep branch points visible
When airflow fails, do not demolish the whole system. The fault is almost always the most recent connection, direction, or corner — inspect that first.
Controls Setup Guide
DUCTWORKS presents most of its interaction through a bottom control bar inside the experience, covering building, adjustment, connection, and testing functions. Exact key bindings beyond standard Roblox movement have not been officially documented, so treat anything beyond the table below as "to be verified in-game."
| Platform | Category | Action | Input |
|---|---|---|---|
| PC | Movement | Move around build area | Standard Roblox keyboard controls |
| PC | Camera | Inspect alignment and corners | Mouse and camera controls |
| PC | Building | Select and place duct parts | Bottom bar + mouse selection |
| Mobile | Movement | Navigate the space | On-screen movement control |
| Mobile | Building | Place and adjust parts | Touch input on bottom bar |
| All | Testing | Run airflow simulation | Relevant visible control in interface |
The game received an update on 2026-10-08, and further multiplayer updates are expected. Always check the in-game bottom control bar for the current tool set.
Step-by-Step: Build Your First Working Duct System
Follow this sequence to go from an empty build area to a tested, expandable HVAC layout.
Explore the Space and Interface
Look over the build area and the bottom control bar. Identify the tools for placing, adjusting, connecting, and testing components before committing to any large construction.
Place a Simple Straight Route
Build a short route with a start point, a few duct sections, and an end point. Keep it straight so every connection can be inspected at a glance.
Connect and Align Sections
Check that neighboring sections meet correctly and that openings face the intended direction. Direction matters even when the route looks visually continuous.
Test the Airflow
Run the simulation and follow the route from source to destination. If the result is wrong, review the most recent connection or direction change first.
Expand Gradually
Add turns and branches one at a time, retesting after each change. This keeps the cause of any new problem obvious.
Once your main route passes a test, you have the foundation for every larger HVAC design in the game — compact layouts, distribution systems, and multiplayer megabuilds all reuse this loop.
Multiplayer: Building With 20 Players per Server
The current update centers on shared construction. With a 20-player server cap, coordination matters more than raw building speed.
Layout Planner
- Maps the main duct route
- Marks connection points
- Approves branch placement
Builder
- Places and connects sections
- Follows the planned route
- Avoids editing contested zones
Tester
- Runs airflow tests
- Records results per design
- Flags broken transitions
| Experiment | Setup | What You Learn |
|---|---|---|
| Direct vs. turned route | Two equal-length paths, one with extra bends | How route shape changes airflow behavior |
| Single vs. balanced branches | One destination vs. split destinations | How branch structure affects distribution |
| Incremental expansion | Add one section per test round | When a layout starts behaving differently |
In group sessions, change only one design element between tests so the team can identify exactly which adjustment caused the observed result.
Beginner Goals and FAQ
First Session Goals:
- Explore the build area and bottom control bar
- Complete a straight test route
- Add and verify one turn
- Add and verify one branch
- Run a multiplayer experiment with friends
There are no officially confirmed Ductworks codes. Do not enter unofficial code strings from third-party lists; only use an in-game redemption feature if one appears in an official update.
Q: What does Ductworks Project 5 mean?
It is a community reference to the current Multiplayer update phase of DUCTWORKS on Roblox, the HVAC and air-duct sandbox by Scaryneff73, updated as recently as October 2026.
Q: Is Ductworks free to play?
The core experience is playable on Roblox without purchase. Optional game passes such as Custom Appearance and Custom Playlist have appeared publicly, but their exact effects should be verified in-game.
Q: How many players can join one server?
The official listing shows a maximum server size of 20 players, which suits coordinated group builds with divided roles.
Q: Why is my airflow not working?
Check the most recent change first: duct sections that do not meet, a section facing the wrong direction, a misaligned corner, or an untested branch are the usual causes.
