Aircon Servicing & Repair in LOHAS Park

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.

You can safely wash or replace filters monthly, keep the outdoor unit clear of leaves and debris, and wipe the indoor casing. Anything involving the refrigerant circuit, electrical components, or coil chemicals should be left to a certified technician — refrigerant handling is legally restricted in most countries.

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.

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 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.
