An operating difference between units needs unit-level evidence

Burj Khalifa recorded one operating FCU and another actuator without supply from the existing controls. Describe which units and rooms are affected, rather than treat a whole-apartment symptom as one established fault. The second-unit correction remains unconfirmed.

A new symptom can be outside a completed installation

Port de la Mer checked its installed Nest controls, while a separate leak was reported not to originate in the drain line. A pump was discussed as a possibility, not diagnosed. Bring the timing and location of the leak to the enquiry; the completed controls item does not answer that question.

A later sound visit should be described separately

The Arabian Ranches sound complaint involved dirt and vibration, followed by an opened section and a reported source correction. Mention whether a sound is new or recurs after earlier work. The record does not justify assuming the same source at another villa.

Prepare the enquiry

Share the affected equipment, what changed, when it occurs and the access available. Include previous work and the open task you want investigated. These are preparation questions, not instructions for electrical or refrigerant work.
