Regular maintenance includes inspections and cleaning at the frequency set out in the plan; repairs and parts replacement are quoted separately.
01First choose the annual service frequencyThese are annual counts, not the number of deep disassembly cleanings each time.
Monthly maintenance
12 times/year
For venues with long operating hours, more cooking fumes, or heavier dust buildup, you may enquire about a more frequent inspection and basic cleaning schedule.
Quarterly maintenance
4 times/year
Follow up on unit condition every quarter, and confirm inspection and cleaning times based on usage and operational arrangements.
Semi-annual maintenance
2 times/year
Inspection and cleaning can be arranged around the AC peak season, according to the plan agreed.
Annual maintenance
1 times/year
Suitable for venues with relatively light usage; whether it is sufficient depends on operating hours, environment and unit condition.

Repair and parts
If a refrigerant leak, aged parts, motor or control-system faults are found, we will first explain the situation and provide separate quotations for labour, parts and required works. Work will only proceed after approval.
Extra works
Additional work such as outdoor condenser cleaning, pipe repairs, access panel work, or work required by site conditions is not automatically included in regular plans.
High-temperature steam cleaning
HK$300 per unit for 1 units; HK$200 per unit for 2 units or more. Additional add-on purchases require confirmation of equipment and material compatibility before work begins.
Maintenance scope
Repair labour and replacement parts are not included in any regular plan and will be quoted separately. Repair services do not include warranty; cleaning maintenance does not apply to repairs or parts.
04The quotation confirms the number of visits and scope, then the site arrangement is confirmed
05What information do we need before quoting a maintenance contract?
For property management offices, restaurants, chain stores and offices enquiring about regular service, please first organise the required details using the list below. This is for proposal checking only, not a fixed annual package; the service scope and commitments are subject to the quotation and terms confirmed by both parties.
Site and unit list
Provide each service address, site use, model and quantity, indoor and outdoor unit locations, and available photos; for chain stores or housing estates with multiple locations, list them separately and do not infer the same work conditions based only on the total number of units.
Work according to operating arrangements
Please explain operating hours, grease or dust buildup, available downtime, and access requirements. Restaurants, offices, and management offices may provide the need for zone-based work, multiple branches, or phased work. Let customer service confirm whether it can be arranged; overnight work is not assumed by default.
Compare plans item by item
Please separately verify the contract term, unit list, annual number of visits, inspection items, and number of deep cleaning sessions; then confirm the total quote, payment arrangement, separately quoted works, and contact method for emergency breakdowns, so that annual maintenance is not mistaken for all-inclusive repairs.
Document and on-site coordination
If the management office has any requirements for entry registration, work notification, designated documents, or the format of a cleaning certificate, please provide the requirements and contact person before confirmation so we can confirm the arrangable scope; this does not mean all documents or certifications are included.

How is the price for commercial air conditioning cleaning confirmed?
First identify the model, quantity, installation height and work location, then check the applicable charge against our commercial cleaning price list. Special systems, hard-to-reach locations and extra work require separate quotation; do not directly replace it with a domestic price.
Enquire about shopWhat information is needed for shop or office cleaning?
Please provide photos of the unit and model, quantity, indoor and outdoor unit locations, as well as the time when the system can be switched off, access arrangements and any site restrictions from the management. For ceiling-mounted equipment, please also state the service access point and working height so protection, water drainage and working space can be confirmed.
Is a one-time cleaning the same as regular maintenance?
No. A one-time cleaning is arranged based on the confirmed model and work scope. Regular maintenance requires separate confirmation of frequency, items covered each time, and the quotation. Parts, repairs, or extra site visits are not automatically included just because there is a maintenance plan.
Can you guarantee that shop operations will not be affected?
Actual shutdown, work and restoration arrangements must be confirmed first, and we cannot guarantee that any premises can be cleaned directly during business hours. When enquiring, please state the business hours, equipment use and any areas that cannot be shut down, so customer service can confirm feasible time slots.

VENUE ARRANGEMENTS
Cleaning arrangements for different commercial venues
Hospitals and healthcare premises
Distinguish ordinary standalone air conditioners from specialist hospital HVAC systems. Confirm unit types, management permission, shutdown windows and protection requirements. We do not operate medical equipment without prior confirmation, and ordinary AC cleaning is not medical-grade disinfection, infection control or specialist system validation.
Provide equipment and installation-position photos, and ask hospital management to specify access rules, restricted areas and required procedures. The scope we can undertake must be confirmed before quotation and scheduling.
Party rooms and event venues
List the rooms, AC types and unit quantities, and reserve a period when the venue is unoccupied. Move or cover projectors, audio equipment, games and upholstered furniture to protect them from wastewater and cleaning products.
Also report leaks, odours or inadequate cooling. Confirm cleaning and fault diagnosis separately. After the work, operation and drainage are checked before venue management arranges reopening.
Clubhouses and shared activity spaces
Confirm contractor registration, residents' activity times and shutdown areas with management, then schedule gyms, reading rooms and activity rooms in batches. For ceiling-mounted and ducted units, check access panels, working height and wastewater collection points.
Shared central systems, pool-related equipment and specialist facilities are not automatically included in ordinary AC cleaning. Provide equipment details and management requirements so that the work boundaries and quotation can be confirmed.
