Water dripping from an indoor unit is a reason to protect people and the affected area, then identify the source through inspection. The place where a drop becomes visible is not necessarily the place where the water originated. Avoid approving a drain-cleaning or pump-replacement scope from the symptom alone.

Put safety before collecting evidence

Keep clear of wet electrical parts, sockets, exposed wiring and unstable ceiling finishes. If you can safely use the normal control from a dry position, stop using the affected unit while arranging an assessment. Do not touch a wet switch, open an electrical cover, bypass a protective device or repeatedly restart the system to see whether the drip stops.

If there is smoke, a burning smell or another immediate hazard, seek appropriate urgent help. Protect belongings only where you can do so without entering the unsafe area. Do not climb, remove a ceiling panel or reach into the unit to collect a better photograph.

Record location and timing precisely

Describe whether water appears at the unit casing, an outlet, a pipe, a ceiling stain or another accessible surface. Note whether it starts during operation, after the unit stops or under another repeatable condition. Record the room and when you first noticed it. Mention recent service or fit-out work as history, not as an accusation about the cause.

A short photo or video taken from a safe position can help locate the complaint. It cannot demonstrate that the drain is blocked or that a pump has failed. If another room also shows water, include it in the same brief rather than treating it as an unrelated detail.

A checked control scope is not a leak repair

At DENAIR's Port de la Mer project, Nest controllers were connected, the application and room names were set up, operation was checked and that controls scope was closed. A separate leak investigation recorded that the water was not coming from the drain line; a pump remained a hypothesis. The available record does not establish the leak's final cause or correction.

This distinction protects the next decision. A successful controller installation does not prove that an unrelated water complaint has been resolved. A possible component fault should stay a hypothesis until the relevant investigation supports it.

What to ask the investigator

Request the identified water source, the equipment or building interface involved, accessible findings and any remaining uncertainty. Ask how the proposed repair addresses that finding and how it will be checked. If concealed access is needed, have the opening and reinstatement responsibility described before work begins.

Keep the initial enquiry focused: room, visible water location, timing, normal operating mode and access constraints. Use AC repair and diagnostics and the AC water-leak scope. DENAIR can assess the relevant site work; this checklist is not a remote diagnosis or a guarantee that drain cleaning is the answer.
