Business Bay towers primarily use fan coil units connected to central chilled water systems, though some newer buildings have VRF (Variable Refrigerant Flow) systems. Our services include fan coil servicing, duct cleaning, split unit installation and repair, thermostat calibration, air quality testing, and drainage line maintenance. The most common issue in Business Bay? Clogged condensate drains that cause ceiling water damage -- we flush and treat drain lines as part of every maintenance visit. Fan coil unit servicing costs AED 300-500 per unit. Duct cleaning for a 1-bedroom apartment runs AED 600-900. We also retrofit smart thermostats for energy-conscious residents and property managers.
