2026AC Cleaning Fee Guide: Quotation Items, Service Scope and Refrigerant Check

Why can AC cleaning quotations differ by several times?

For AC cleaning charges, first distinguish the model, cleaning scope, quantity and installation location; do not compare only a starting price. This article is compiled from our company's current service arrangements on 2026-10-26; it does not treat old market prices or holiday surcharges as the current price list. Please refer to the service and pricing links at the end for the actual amount, and confirm any special locations or extra work with a quotation in advance.

1. Check cleaning fees by model and scope of work

For a window unit: first confirm the unit size, whether it can be safely removed, and the work access position, then compare with the current price list. Do not assume that handling of dangerous positions or extra dismantling and installation is always included in the basic charge.

Split unit: distinguish clearly between indoor unit cleaning and outdoor unit work, and state the horsepower, model, and location; do not assume the indoor cleaning price automatically includes the outdoor unit, refrigerant inspection, or fault repair.

Ceiling-mounted AC: please provide the panel, unit model, ceiling height and site photos to confirm the working space, drainage arrangement and cleaning scope, then proceed according to the current commercial price list or a separate quotation.

Central air-conditioning: equipment, system scope, construction hours and site restrictions vary greatly, so the actual configuration must be stated first; the total system cost cannot be calculated simply from the per-unit price of residential air-conditioners.

District differences:

Whether there is an additional charge for cross-district visits, remote locations and work arrangement needs to be confirmed according to the current service scope and quotation; it cannot be said that all Hong Kong Island jobs require extra charges.
Please provide the actual address and property type so customer service can first confirm the service scope and site conditions, instead of estimating the charge based only on Hong Kong Island, Kowloon or New Territories.
Whether outlying islands, transport or access restrictions involve extra arrangements should be checked first and included in the quotation, rather than applying a generic transport surcharge.

II. 7 major factors affecting AC cleaning prices

AC types: window, split, ceiling and central AC involve different work procedures and equipment; compare by the actual scope of work, and do not assume one type is always the cheapest or most expensive.
Cleaning scope: confirm how the filter, evaporator, fan wheel and drainage areas will be handled; cleaning, disinfection, stain removal and dismantling are not the same, and any required work must be confirmed according to the model and quotation.
Horsepower and quantity: check the applicable model, horsepower range and number of units according to the current price list, and do not assume there is a fixed surcharge for every additional half horsepower.
Equipment condition: ageing, rust, damage, or previously repaired areas should be stated in advance. First assess whether the work can be carried out; do not assume an extra charge simply because the unit is older than a certain age.
Installation location: high or hazardous locations, and environments where dismantling and reinstallation are difficult, will be charged based on site conditions.
Service hours: first confirm available dates and whether special working hours are involved; do not rely on any unverified weekend surcharge of 20% to 50% or urgent-service surcharge of 50% to 100%. Any actual extra charges must be confirmed in advance.
Additional work: Filter or parts replacement, fault checks and refrigerant system handling must be confirmed separately. Cleaning does not mean topping up refrigerant; if cooling is abnormal, the cause should be identified first and handled by personnel with the relevant training and equipment, without opening the sealed system yourself.

3. Area and site arrangements must be confirmed first

First provide the address, management office access arrangements, available work hours, parking and equipment access points. If there are extra transport or work requirements, please state them before service is confirmed.

Multi-unit cleaning and group enquiries:

You may first inquire about available time slots, but do not assume weekdays or off-peak periods are necessarily cheaper.

For multiple air conditioners at the same address, charges will be checked against the current price list and applicable conditions; do not assume all models qualify for the same promotion.

For group cleaning across households, please state the number of households, number of units, whether they are in the same or nearby estates, and whether same-day arrangement is possible, then confirm the quotation separately. Unverified off-season discounts do not apply.

4. Ask clearly about the quotation and service commitment

Additional charges: confirm the known scope of work before arrival; if extra issues are found after inspection, explain the items and charges first, then decide whether to proceed.
Parts replacement: please state the cause of the fault, the part model and the replacement cost, and do not confuse cleaning services with repair or parts maintenance.
Cleaning products: choose according to the model, materials and product instructions. Service quality is not determined by whether a strong chemical is used, and stronger chemicals do not mean better results.
Fake discounts: beware of inflating prices before applying a discount. Choose a reliable AC company
Maintenance terms: distinguish between post-cleaning coverage, existing faults and repair arrangements; the maintenance scope and eligibility must follow the current terms, not just a stated number of months.

V. How to choose a reliable AC cleaning company?

When comparing companies, check whether the process, quotation items, on-site protection, receipt and after-sales terms are clear. You cannot judge cleaning quality for all models simply by whether parts are removed or chemicals are used.
Verify the service and written terms through the company's public contact channels, and pay attention to whether reviews are specific; unless qualifications are verified, do not treat terms such as ‘best’ or ‘Consumer Council approved merchant’ as official endorsement.

6. The difference between daily maintenance and professional cleaning

Routine maintenance: stop operation first, cut off the power according to the user manual, and only handle filters or casing that the original manufacturer allows users to clean. Refit only after it is dry, and do not spray water on electrical parts.

Deep cleaning inside the unit: if disassembly, internal rinsing or work at the outdoor location is involved, it should first be assessed by personnel with relevant experience to confirm waterproof protection, access and work safety. Do not lean in or move the support yourself.

Key points for maintenance arrangements:

Arrange maintenance based on usage frequency, dirt buildup, and the manufacturer’s instructions; if cooling remains poor, the breaker trips, or there is water leakage, further inspection is needed, and repeated cleaning alone is not enough.
Filter cleaning frequency should be adjusted according to usage and the user manual, and every two months is not a hard standard for all models.
If there is ageing, damage or a past fault, please state it first; do not decide that only cleaning is needed or that the unit must be replaced based solely on being over five years old.

7. Information to confirm before enquiring in 2026

Cleaning products and methods: confirm according to the model and product instructions; without test conditions, do not promise water-saving ratios, sterilisation results, or that they are safer for all materials.
Please provide photos of the unit, service access, model and installation/access points, and confirm the scope of work first; if you need before-and-after photos or special records, please state this when booking.

To verify: confirm the company

Regular professional cleaning can help keep the air conditioner in working condition. If you have a persistent cough or feel unwell, consult a doctor as soon as possible to determine whether it is related to air quality; equipment maintenance is not a substitute for medical advice.
