AC maintenance that keeps the building running.
Split, ducted and VRF systems serviced on a written schedule — coils, gas, drains, electrics and ducting — by our own licensed crews, around occupancy.
What a service actually covers.
The difference between a cheap visit and a real one is what gets measured and written down. Below is what we do on every planned visit, and what gets recorded.
- Filters cleaned or replaced, with type and size recorded
- Evaporator and condenser coils cleaned — chemical where fouling warrants it
- Drain pan and condensate line flushed and flow-tested
- Refrigerant pressures read and compared against design figures
- Electrical connections, contactors and capacitors checked and tightened
- Thermostat calibration and airflow at the grille checked
- Readings taken, not just ticks in boxes
- Asset list with make, model, location and service history
- Faults found and whether they were corrected or need quoting
- Parts fitted, with the supplier invoice where chargeable
- Date and engineer name on every sheet
Different systems, different failure modes.
| System | Typical interval | What usually fails first |
|---|---|---|
| Wall and floor split units | Every 3 months | Blocked drains, fouled evaporator coils, failed capacitors |
| Ducted / concealed units | 3–6 months | Filter bypass, duct leakage, drain pump failure, access neglected |
| VRF / VRV systems | 3–6 months | Refrigerant leaks at branch joints, control and addressing faults |
| Package and rooftop units | 3 months | Condenser fouling from dust, belt and bearing wear, corrosion |
| FAHU and ventilation plant | 6 months | Filter loading, damper linkages, fan bearings, coil fouling |
Intervals assume normal commercial use in Dubai conditions. A kitchen, a workshop or a site near open ground will need more frequent attention, and we will say so after the survey rather than after the breakdown.
Clean units, dirty ducts.
A serviced unit pushing air through loaded ducting still delivers poor air. Duct cleaning is separate work and should be priced and scheduled separately.
- Access panels formed where none exist, and made good afterwards
- Mechanical brushing with vacuum extraction under negative pressure
- Grilles, diffusers and volume control dampers removed and cleaned
- Drain pans, coils and plenum chambers cleaned at the same time
- Before and after photographs at each access point
- Dust visible at supply grilles, or settling quickly after cleaning
- Persistent smells that return after the units are serviced
- After any construction, fit-out or demolition work in the space
- Clinical, food and laboratory areas on a fixed schedule
- On change of tenancy, before anyone moves in
Put it on an annual maintenance contract
When a unit is worth keeping.
We quote the repair and the replacement side by side with the running-cost difference, and let the numbers decide. A contractor who only ever recommends replacement is selling units, not maintenance.
- Capacitors, contactors, thermostats and sensors
- Drain pumps and blocked condensate lines
- Fan motors and bearings on otherwise sound plant
- A single leak found and fixed at a known joint
- Compressor failure on a unit past its service life
- Repeated refrigerant loss with no locatable leak
- Corroded coils on coastal or rooftop installations
- Obsolete refrigerant with no supportable spares route
Common questions.
How often should an AC system be serviced in Dubai?
Most split systems need servicing every three months and ducted or VRF systems every three to six, because dust load and run hours here are far higher than the manufacturer's temperate-climate assumption. A system running continuously through summer in a dusty location may need more.
What should a proper AC service include?
Filter clean or replace, evaporator and condenser coil clean, drain pan and condensate line flush, gas pressure check, electrical connections and contactor check, thermostat calibration, airflow check and a written record of the readings. A visit that only changes a filter is not a service.
How do I know if the gas needs charging?
Low cooling with normal airflow, ice on the suction line, or a measured pressure below the system's design figure. Gas does not get consumed — if a system needs charging repeatedly there is a leak, and recharging it without finding the leak is throwing money away.
Do you clean ducts as well as the units?
Yes. Duct cleaning is separate work from unit servicing: brushing and vacuum extraction through access points, grille and diffuser cleaning, and where specified, inspection of the internal lining. Dust and biological growth in ducting affects air quality regardless of how clean the unit is.
Can the work be done without shutting the premises?
Usually. Units are taken offline in sequence rather than all at once, and heavier work such as duct cleaning is scheduled for evenings, weekends or quiet periods so the space stays usable.
What happens if a unit fails outside a scheduled visit?
Under a maintenance contract, four hours for an emergency and twenty-four hours for a standard call-out — written into the contract, not offered as a courtesy. Without a contract, we attend as capacity allows.
Tell us how many units and where they are.
We will survey, list the assets and quote the schedule itemised — planned visits and call-out cover priced separately so you can see what you are paying for.
