Key takeaways
- Most aircon servicing & repair jobs in Hong Kong land between HK$400–HK$2,500 — known locally as aircon cleaning & repair (冷氣機清洗維修).
- Hong Kong requires registered electrical workers (EMSD) for fixed electrical work, and building management rules in most estates control the mounting and dripping of air conditioners — dripping condensate onto other flats or the street is an enforceable nuisance under the Building Management Ordinance and can draw FEHD action.
- Prices below are researched national ranges, updated July 2026 — not quotes.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Hong Kong typically run above the national range; smaller towns below it.
How to save
- Get at least three quotes and compare like-for-like scopes, not just totals.
- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.
How to hire a aircon servicing & repair pro in Hong Kong
- Confirm the unit type — split, window, or ceiling cassette — prices differ substantially and window units dominate older buildings
- For any fixed wiring work, the worker must be a registered electrical worker under the EMSD scheme
- Ask whether the quote covers deep cleaning (coil and blower removal) or a surface wash only
- Agree the price and scope over the phone or in writing before the visit — on-site upselling is common
- For window units in high-rises, confirm the company insures against falling-object liability during removal/refit
- Check reviews on Google or local platforms (e.g. Toby/HelloToby) for the specific company
Red flags
- Quotes a low cleaning fee then finds 'urgent' faults requiring expensive parts on site
- No company name or receipt — many operators are informal
- Recommends refrigerant top-ups annually
- Removes a window unit without safety harness or protective measures over the street
- Won't state whether parts are new or salvaged

Frequently asked questions
Should I get an inverter or non-inverter unit when replacing?
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.
Why is my aircon running but not cooling?
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.
Can I service my air conditioner myself?
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.
My aircon trips the circuit breaker — what does that mean?
A unit that trips the breaker at startup usually has a failing compressor, a shorted capacitor, or a wiring fault — all electrical faults that need a technician. Do not keep resetting the breaker; repeated tripping can damage the compressor beyond repair.
Why is my aircon leaking water indoors?
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.
Is it worth signing an annual aircon maintenance contract?
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.
How much does aircon cleaning cost in Hong Kong?
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.
My aircon drips onto the flat below — who is responsible?
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.
