In Dubai, air conditioning runs for most of the year, often 24 hours a day in summer. That workload — combined with fine dust and humidity — means AC units need more frequent care than manufacturers' generic schedules suggest.
The short answer
- Homes: a full service every 3–4 months, and always before summer.
- Offices and shops: every 2–3 months, depending on occupancy and hours.
- Filters: wash every 2–4 weeks in summer if you can access them.
- Duct cleaning: every 1–2 years.
What a proper service includes
A real service is more than spraying the filter. It should include washing filters, chemically cleaning the indoor and outdoor coils, flushing the drain line, checking electrical connections and capacitor health, measuring refrigerant pressure and checking supply-air temperature.
Signs your AC needs attention now
- Rooms take longer to cool, or never quite reach the set temperature
- Water dripping from the indoor unit
- A musty smell when the AC starts
- A sudden jump in your DEWA bill
- Ice on the copper pipes
Why it saves money
Dirty coils make the compressor run longer for the same cooling. Keeping coils clean and refrigerant at the right level helps the system run efficiently, reduces breakdowns in peak summer, and extends the life of the most expensive component — the compressor.
