Aircon Servicing & Repair in Dubai

Inverter units vary compressor speed instead of switching on and off, so they hold temperature more steadily and cost 20-40% less to run for long daily use. Non-inverter units are cheaper upfront and fine for rooms cooled a few hours a day. For daily whole-day use, the inverter premium usually pays back in 2-3 years.

Once a year is the minimum for a system used seasonally; every 3-4 months if you run it daily in a hot climate. Regular servicing keeps coils and filters clean, which protects the compressor — the most expensive part to replace — and keeps energy use down.

A standard service covers cleaning or replacing filters, cleaning the evaporator coil and blower, flushing the drainage tray and pipe, checking refrigerant pressure, testing thermostat and controls, and inspecting electrical connections. It does not include repairs, parts, or refrigerant top-ups — those are quoted separately.

A chemical wash uses a cleaning solution to strip dirt and mould from the evaporator coil, blower wheel, and drain pan without dismantling the whole unit. Book one when a normal service no longer fixes weak airflow, bad smells, or water leaking from the indoor unit — typically every 12-18 months for heavily used units.

The most common cause is a clogged condensate drain line — dirt and algae block the pipe and water backs up into the room. Other causes are a dirty evaporator coil that ices over and then melts, a cracked drain pan, or an incorrectly sloped drain pipe. A drain flush during a standard service usually fixes it.

Check the simple things first: thermostat mode and setpoint, dirty filters, and blocked outdoor unit airflow. If those are fine, the usual culprits are low refrigerant from a leak, a failed capacitor or fan motor, or a dirty coil. Low refrigerant always means a leak — a technician should find and fix the leak, not just top up the gas.

A one-off service visit for an apartment (2-4 FCUs) runs AED 200-400; a villa full-system service AED 300-600. Annual maintenance contracts covering 2-4 visits typically cost AED 400-900 for apartments and AED 800-2,000 for villas depending on unit count.

Condensate volume peaks in humid months and any partial drain blockage overflows. UAE dust makes drain lines clog faster than in most countries — a drain flush every service visit, not just once a year, is the practical fix in high-humidity emirates.
