Learn step-by-step how to install the Duux Universal Wall Mount Exhaust Hose for your mobile air conditioner. This guide covers wall mounting, hose routing, and common pitfalls.
Quick answer
The Duux Universal Wall Mount Exhaust Hose lets you vent a mobile air conditioner through a wall instead of a window. Follow these six steps to mount it securely and avoid air leaks.
Why use a wall mount instead of a window kit
A wall-mounted exhaust hose is ideal when you cannot use a window—for example, in a basement, a room with sliding doors, or a space where you want a permanent vent. The Duux wall mount creates a sealed exit point through an exterior wall, so hot air leaves the room efficiently without compromising security or insulation.
What you need before starting
You will need the Duux Universal Wall Mount Exhaust Hose (model DXMAWM01), a drill with a hole saw (typically 5–6 inches depending on your hose diameter), a tape measure, a level, and exterior-grade sealant or foam tape. The kit does not include a drill or hole saw, so plan ahead.
Installation steps
- Choose the wall location: Select an exterior wall near the air conditioner. Avoid areas with electrical wiring or plumbing. Mark the center point for the hole using a level to ensure the bracket sits straight. Check for hidden pipes or wires before drilling—use a stud finder or consult local codes.
- Drill the exhaust hole: Using a hole saw that matches your hose diameter (check the Duux bracket specs), drill a hole through the wall from inside to outside. Angle the drill slightly downward so water does not enter the wall cavity. A downward angle prevents rain from seeping in. If drilling through brick, use a masonry bit and pilot hole first.
- Install the wall bracket: Insert the Duux wall mount bracket into the hole from the outside. Secure it with the provided screws or anchors. Apply exterior-grade sealant around the flange to weatherproof the seal. Do not overtighten the screws—you could crack the bracket. Let the sealant cure fully (check label) before attaching the hose.
- Attach the exhaust hose: Connect one end of the exhaust hose to your mobile air conditioner’s outlet. Then attach the other end to the wall bracket’s interior side. Use the clamp or locking ring included with the Duux mount to secure the connection. Ensure the hose is not kinked or compressed—a bent hose reduces airflow and cooling performance.
- Seal the interior connection: Apply foam tape or sealant around the interior wall plate where it meets the wall. This prevents hot air from leaking back into the room and keeps insects out. A poor seal here is the most common cause of reduced efficiency. Test by running the AC and feeling for drafts around the plate.
- Test the system: Turn on the mobile air conditioner in cooling mode. Check that air flows freely through the hose and out the wall vent. Listen for unusual noises and feel for air leaks at every connection. If the AC cycles off unexpectedly, the hose may be blocked or the bracket may be undersized—verify the hole diameter matches the hose.
