A ducted system needs a practical path for room air to return to the equipment. This tutorial is a floor-level check of the accessible space around the return-air grille, not an instruction to open a ceiling or alter ducts.

Before you start
Use your handover documents to identify the return-air grille. If you are unsure which grille it is, ask the installer before changing anything.
Step-by-step tutorial
- Identify the area. Mark the return-air position on a simple floor plan and note any furniture or storage immediately around it.
- Look for obstruction. From floor level, check whether household items are covering or crowding the grille. Move only loose belongings you can handle safely.
- Review the normal room layout. Note how the household uses doors and adjoining rooms. Ask the installer which return-air path the design expects.
- Record visible condition. Take a photo of visible dust, damage or a loose grille. Do not lift a heavy ceiling grille or reach into an opening.
- Confirm the next task. If the manual identifies an owner-serviceable filter, use only those instructions and safe access. Otherwise book the appropriate service.

Check the result
The area should remain accessible and free of accidental storage obstruction. Keep the floor-plan note with the controller instructions so someone moving furniture later understands why the space matters.
Stop and get professional help if needed
Do not enter a roof space, reach through a grille, change dampers or force a ceiling panel. If a grille is high, loose or damaged, or you cannot identify its purpose, request professional help.
A common question
Should I shut every unused room door?
That depends on the ducted design and return-air arrangement. AirTouch’s ducted guidance describes the importance of return airflow; ask the installer how your property is intended to operate.
