Split, ducted or central AC: which system is in your Dubai home?

Before you book anything, work out what you actually have. Half of all mismatched quotes in Dubai come from a customer describing a ducted system as a "split".

Wall-mounted split

An indoor unit on the wall, a condenser outside on a balcony or roof. One unit per room, individually controlled.

• Common in: older apartments, villas, studios, extensions
• Typical faults: dirty filters, blocked drains, capacitor failure, gas leaks
• Service cost: lowest per unit; scales with number of units
• Who fixes it: any residential AC company

Ducted split

The equipment is hidden above a false ceiling; you only see grilles and a wall thermostat. Still a self-contained system with its own outdoor condenser.

• Common in: newer apartments, mid-range villas
• Typical faults: blocked drain trays above ceilings (expensive when they leak), duct leakage, blower and belt issues, airflow imbalance between rooms
• Service cost: higher — access panels, ceiling work, sometimes two technicians
• Watch for: whether there is an access hatch at all. If not, budget for making one

Central / district cooling (chilled water)

No condenser of your own. Chilled water arrives from a plant serving the tower or community; your apartment has a fan coil unit and a thermostat, and you get a separate cooling bill with consumption and capacity charges.

• Common in: towers in Downtown, Business Bay, Marina, JLT, and master communities
• Typical faults: stuck or failed control valve, dirty fan coil, thermostat faults, air locks — plus supply-side issues that are the provider''s problem, not yours
• Service cost: fan coil servicing is comparable to a ducted split; the chilled water supply is out of scope for a residential contractor
• Important: if the whole building is warm, do not pay for a technician — contact building management

Window and package units

Single boxed units, usually older buildings, warehouses, labour accommodation and site offices. Cheap to service, cheap to replace, noisy.

VRF / VRV

One outdoor unit feeding several indoor units with variable refrigerant flow. Common in larger villas and offices. These need a contractor familiar with the specific manufacturer — a generic split technician will not have the service tool or the fault codes.

How to identify yours in 30 seconds

1. Look at the ceiling: grilles only = ducted or central.
2. Look outside: your own condenser = split, ducted split or VRF. None = district cooling.
3. Look at your bills: a separate cooling invoice with a capacity charge = district cooling.
4. Look at the thermostat: a valve-driven system usually has a simple wall thermostat with fan speed and no cooling modes beyond on/off.

Telling the provider the right system type up front is the single biggest factor in getting an accurate quote — which is why our request flow asks for it before dispatching.
