Aircon Servicing & Repair in Aberdeen

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 standard clean-and-check takes 30-45 minutes per indoor unit. A chemical wash takes about an hour per unit, and a full chemical overhaul (where the unit is dismantled) takes 1.5-2 hours per unit. Multi-unit visits are faster per unit.

A standard clean of a split-type indoor unit runs HK$400-$800; a deep clean with coil/blower removal is HK$700-$1,200. Window units cost HK$400-$700 to clean and slightly more if removal and refit is needed. Multi-unit bookings get per-unit discounts.

You are, as the owner of the unit. Dripping air conditioners are a common source of complaints under building deeds of mutual covenant, and FEHD can issue nuisance notices. A drain-pipe clear or re-slope during a service visit usually fixes it — do not ignore management office letters.
