Residential AC cleaning service

Whether it is a window unit or a split-type unit, built-up dust and mould can affect cooling performance and cause odours. We use a high-pressure water jet for deep cleaning; the cleaning service includes 90 days of warranty, covering issues caused by the cleaning service. Cases involving dripping or water leakage must first be checked to confirm the cause and applicable terms. Please contact customer service for details before booking.

Residential window and split-type unit cleaning is subject to the current price list on this website. Multi-unit discounts require same-estate or nearby-estate, same-day service arrangements; cross-household group-buy quotes are handled separately and do not directly apply the residential multi-unit price. Please provide the unit type, quantity, and location first. If additional services are needed or repairs are discovered on site, a separate quote will be provided first, and extra work will only begin after confirmation.

ADD-ON SERVICES

AC add-on services

Below are the charges for each AC add-on service; please provide the model, quantity, location and photos of the issue first. Confirm the scope of work, applicable parts and extra work charges before proceeding, and work will only start after approval.

    Refrigerant top-up

    Per unit
    HK$1,000–HK$1,800Per unit

    Confirm the quantity by model, refrigerant type and actual need; first check the cause of poor cooling, as refrigerant top-up is not needed in every case.

    Choosing Daikin refrigerant costs an extra HK$100 per unit; leakage repair and other works are to be confirmed separately.

  • Drain clearing using a Worx wet vacuum Illustration

    HK$200Per unit

    Use a vacuum machine to deal with drainage issues according to the drain pipe and the level of blockage. AC cleaning service already includes clearing the drain pipe with a high-pressure water jet, so this is not needed every time as an extra item.

    The drain pipe service includes 3 months of maintenance; the cause of the leak must be verified and the applicable scope confirmed at the time of booking. This does not mean that all causes of leakage are covered or that it is guaranteed never to leak again for one year.

  • Outdoor unit cleaning Illustration

    HK$400Per unit
    2 unit(s) or more
    HK$300Per unit

    Removing dust from the outdoor condenser helps maintain heat dissipation; long-term dust build-up may affect cooling and increase the load on the equipment.

    Use high-temperature steam to assist in cleaning dirt and removing odors according to the equipment and material suitability; it does not replace the original dismantling and washing process.

    After cleaning, apply the coating according to the surface material and product instructions. Confirm suitability and usage precautions before application.

    “180 Days” is a marking in the product name. Actual performance and duration must be based on tests and usage conditions for the applicable product, and there is no guarantee of eliminating any specific virus or that it is harmless to all people and pets.

SERVICE SCOPE

Service coverage and booking notes

The included and excluded items in the base price, repair conversion cases and booking preparation are listed separately for easier checking.

01

What does the basic price include?

For a window unit: first assess the removal arrangement, then clean the casing, dust filter, evaporator coil, condenser coil, fan wheel, base tray and drainage area, and finally reassemble, reinstall and test the unit.

View the cleaning scope for each unit type
  • Split unit: clean the indoor unit casing, dust filter, fan blades and blower wheel, cooling fins, drain pan, and drain pipe; protect against water and collect runoff properly, then test after reassembly.
  • Includes pre-cleaning inspection, surrounding protection and tidying up the work area after completion; the actual dismantling and cleaning will be arranged according to the model and the condition of the equipment.
02

Not included and steam add-on

The basic price for a split unit does not include cleaning of the outdoor heat exchanger; the fins of a window unit itself are within its dismantling-and-cleaning scope, and no separate split-unit outdoor add-on applies.

View other excluded items
  • High-temperature steam is an extra add-on and is not included in basic cleaning; charges are based on the add-on service price list on this page.
  • Does not include adding refrigerant, installation, part replacement, or repairs. Extra work will be explained and quoted first, and only carried out after agreement.
03

When should it be changed to repair?

Refrigerant leakage, broken pipes or connection issues, motor, fan and control part faults need separate inspection and repair. Cleaning cannot replace repair.

View other repair situations
  • If the drain pan or drain pipe has aged and cracked, there is an installation slope issue, or leakage continues after clearing, the cause must be confirmed first and quoted separately.
  • Dust buildup or blockage can be assessed for improvement through cleaning; however, cleaning does not guarantee that cooling, airflow or water leakage will be fully restored.
04

Preparation and photos before booking

When booking, provide the model, quantity, nameplate, full view of the unit and installation location; if there is a fault, include photos of rust or the leak location, or a short fault video.

View pre-booking preparation
  • Photograph the space under and around the unit, remove clutter, documents and items that can easily be damaged by moisture, and reserve enough space for the technician, tools and waterproof protection. Whether the space is sufficient must be assessed on site; there is no standard square footage.
  • A window unit needs a suitable place for moving and cleaning; a split unit needs safe access to the cabinet. Please advise any space limitations first.
  • The unit must be switched off during cleaning, and there is no need to dismantle the unit, remove parts or handle wiring yourself. The time required depends on the model, dirt level and work conditions.
05

High-mounted units, access hatches and equipment constraints

If the unit is too high, the access panel is too small, the body is heavily rusted, or it cannot operate normally, please tell us in advance when booking and provide photos and measurements so we can assess whether the work can be done.

View on-site assessment arrangement
  • The actual workable scope must be confirmed on site; if safe work cannot be carried out, we will not force dismantling, cleaning, or repairs. If additional arrangements or repairs are needed, they will be explained and quoted first, and only carried out after approval.
How do I report after-sales issues?

If there is a problem after service, please contact customer service via WhatsApp, phone or email and provide the following information so we can verify the service and the cause of the issue.

  • Service date, booking name and contact number.
  • Service address, and the unit, model or service item with the issue.
  • When did the problem occur, what exactly happened, and provide clear photos or short videos.
  • If you have a quotation, payment record or service receipt, please provide them as well.

Customer service will first check the records and the cause of the problem, then confirm whether maintenance applies, how it will be followed up, and any possible charges; reporting a problem does not mean all faults will be repaired free of charge.

Booking, payment and rescheduling

Payment, rescheduling and cancellation arrangements

01

Payment methods, deposit and balance

  • Bank transfer, FPS, cash, PayMe, and Alipay are accepted.
  • A deposit of HK$500 is required for cleaning and repair bookings.

Reschedule: free if changed at least 24 hours in advance

  • For cleaning, repair, and installation, you may reschedule free of charge if you notify us at least 24 hours before the appointment.

03

Cancellation and refund for no-show

  • If the booking is cancelled directly before the technician arrives, a HK$300 cancellation fee will be charged for all services, regardless of how far in advance notice is given; free rescheduling in advance does not mean free cancellation.

Homeair conditioning cleaning FAQ

Understand the applicable scope, charges and arrangements before booking

What models are included in household AC cleaning charges?

Our residential cleaning price list on this site applies to window-type and split-type units, with charges based on the number of units cleaned. Other models, special locations and extra work must be confirmed separately; the residential rate cannot simply be applied by horsepower.

Does split-unit cleaning include the outdoor unit?

Basic indoor split-unit cleaning does not include the outdoor condenser. When enquiring, please provide separate photos of the indoor and outdoor units. We will first confirm whether the location is safely accessible, then check the scope we can take on and any additional charges.

What is the difference between multi-unit discounts and cross-household group bookings?

Household multi-unit offers must be arranged on the same day and within the same estate or nearby estates; group bookings across different households require a separate quotation and do not directly use household multi-unit pricing. Please provide the total number of units, model types and locations so customer service can confirm eligibility.

Can AC cleaning solve all dripping or cooling problems?

No. Cleaning deals with dust buildup and the applicable cleaning scope; it does not replace fault diagnosis or part repair. Existing dripping, poor cooling, or tripping should be stated before booking. Cleaning comes with 90 days of warranty, and the cause and applicable terms must be verified for each case; not every dripping issue qualifies for free repair.
