Aircon Servicing & Repair in Kowloon City

Dirty coils and filters make the compressor work harder for the same cooling — energy use can rise 15-30% before you notice weaker airflow. A failing capacitor or low refrigerant has the same effect. A service that restores the unit to spec usually pays for itself in a hot season.

A common rule: if the repair costs more than half the price of a new unit, or the system is over 10-12 years old and needs a compressor or coil replacement, replace it. Newer inverter units are typically 30-50% more efficient, so heavy users recoup part of the cost through lower bills.

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.

Most charge a call-out or diagnostic fee that covers travel and the first inspection; many waive or credit it against the repair if you go ahead. Confirm the fee, whether it is credited, and any surcharge for evenings, weekends, or urgent same-day visits before the technician is dispatched.

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.
