Downtown Dubai towers use various AC configurations -- most residential buildings run on central chilled water with fan coil units in each apartment, while some newer developments have individual split or VRF systems. Our services include fan coil servicing and motor replacement, duct cleaning, condensate drain maintenance, thermostat calibration, split unit installation, and air quality assessments. Fan coil unit servicing runs AED 300-500. Duct cleaning for a 2-bedroom apartment costs AED 1,000-1,500. We offer priority maintenance contracts for Downtown residents starting at AED 800 per year, with guaranteed 4-hour response times for emergencies.
