Aircon Servicing & Repair in Sham Shui Po

Get 2-3 quotes and compare what each service actually includes — some cheap quotes cover only a filter rinse. Check for the refrigerant-handling certification required in your country, ask how long they have serviced your brand and type of system, and read recent reviews that mention follow-up visits, not just the first appointment.

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 cleans the coil, blower, and drain pan in place. A chemical overhaul dismantles the indoor unit completely, soaks the parts, checks bearings and seals, and reassembles it. Choose an overhaul when a wash has not fixed persistent leaks, noise, or weak cooling, or for units neglected for years.

If you run multiple units daily, yes — contracts usually price each visit 15-30% below one-off rates, include priority booking during heatwaves, and some include minor parts. For a single, lightly used unit, paying per visit is usually cheaper.

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.
