Every 4 to 6 months in Dubai. Cassettes pull air from the whole room through a wide return grille, so they load with dust faster than most people expect, and the blower wheel in particular collects a film that cuts airflow noticeably.
A ducted system uses one indoor unit and a network of ducts to distribute air through multiple outlets, while split AC uses a separate indoor unit per room. Ducted looks cleaner and cools more evenly, but the duct network needs its own periodic cleaning.
Every 12 to 18 months for most homes; every 6 months for restaurants, clinics or heavy-traffic commercial spaces.
Every 3 to 4 months for filter/coil cleaning in Dubai's dusty conditions, with a deeper service annually.
We recommend a scheduled AMC with at least two visits a year, given the complexity of the refrigerant piping and the number of indoor units typically involved.
Every 3 to 4 months given dust levels in the UAE, more often in accommodation blocks or storage areas with heavier use.

Every 12 to 18 months for most homes, or annually if you're near a construction site, have pets or allergy sufferers, or moved into a newly handed-over property.
Coil cleaning targets just the evaporator and condenser coils and takes under an hour; full duct cleaning also cleans the entire duct network and takes several hours. If your ducts were cleaned recently but cooling has dropped off, coil cleaning alone is often enough.
Every 3 to 4 months given the dust levels here, especially for outdoor condenser units exposed to sand and construction dust.
