How much does AC cleaning cost in Dubai for a 3-bedroom apartment?

For 3 split AC units in a JVC apartment, expect to pay AED 80–150 per unit for a standard clean, so AED 240–450 for all three. Most engineers will give a slight discount for multiple units in the same visit. The rattling sound is worth addressing — it's usually caused by a loose fan blade, debris caught in the unit, or a worn bearing. Left untreated, a rattling unit can fail completely in the middle of summer when you need it most and when engineers are at their busiest. Ask the engineer to diagnose the rattle as part of the cleaning visit — it may be a simple fix at no extra cost, or a minor part replacement. Don't leave it until summer.
