Commercial wall-mounted split AC cleaning in Hong Kong
Commercial Wall-Mounted Split AC Cleaning
When offices, shops, schools or multi-site portfolios have several wall-mounted split units, the quotation needs to match each location, accessible component, protection requirement, drainage arrangement and available work period. Evolt Cool Engineering then plans the work and handover records around the confirmed scope.
- Identify every unit and location
- Confirm protection, drainage and timing
- Clean and hand over to the listed scope

A commercial multi-unit plan, not a household one-off
Wall-mounted split units can be located in different rooms, floors or branches. The area below, available work period, drainage condition and operational need can vary for every asset, so the quotation and completion record should match the actual location.
Offices and meeting rooms
Account for workstations, meetings, documents, electronic equipment and rooms that can be taken out of use.
Shops and back-of-house areas
Include trading hours, displays, stock, and the access rules set by the landlord or property manager.
Schools and community premises
Plan the available work period and return sequence around room use, occupants, school calendars or service hours.
Multiple branches or floors
Use site, room and equipment location to prevent omissions, duplicate counts or handover records that cannot be reconciled.
Prepare the quotation inputs
Tell us where each unit is and when it can be worked on
A mixed-site scope uses the equipment types, locations and total quantity to define the work. You can enquire before every detail is ready, but the following information helps align the quotation with the premises.
- 01
Site, floor, room or branch, with the quantity at each location
- 02
Unit type, model, exterior photos, and whether it belongs to a single-split, multi-split or another system
- 03
Mounting height, furniture, stock, equipment, finishes and working space below the unit
- 04
available work period, access procedures, permits, and power or control isolation requirements
- 05
Leaks, odour, weak airflow, noise or insufficient cooling, plus recent maintenance or repair records
- 06
Required photos, unit-by-unit records, report format, sign-off process and other handover needs
Start a multi-unit quote with a reconcilable list
General commercial setting shown. The actual equipment location, photos, rooms and handover fields depend on the site and quotation requirements.
Plan the area before cleaning starts
Five main steps for wall-mounted split AC cleaning
Wall-mounted indoor units often sit above occupied areas. Before work begins, confirm safe access, whether the area below can be cleared, which surfaces need protection, and how wash water will be collected and handled.
Protection must suit the area below the unit
General commercial setting shown. Wall, furniture, equipment, floor, work-zone and wash-water controls are confirmed for the actual site.
- 01
Confirm the units and quoted scope
Match each indoor unit to its room or zone, model, quantity, photographs, quoted components and available work period.
- 02
Protect walls, furniture and access
Arrange shutdown and isolation, separate the work area, fit wet-work protection and confirm wash-water collection or drainage.
- 03
Clean the stated components
Use the method appropriate to the model for the casing, filter, safely accessible coil, blower, drain pan and drainage components.
- 04
Refit and check basic operation
After drying, refit the unit, restart it and check basic cooling response, airflow, unusual noise and visible drainage.
- 05
Check completion unit by unit
Confirm the cleaned components, reinstatement, basic observations and repair items that still require follow-up.
Put included work and separately assessed items in the quotation
“Clean one high-wall unit” still needs a component boundary
Models, contamination, installation positions and dismantling needs vary. These are points to confirm in the quotation, not a promise that every item is automatically included before the site and unit are reviewed.
can be included when specified
Accessible indoor-unit components
- Casing, panel, louvres and filters
- Safely accessible coil, blower wheel or fan areas
- Drain pan and the defined accessible drainage section
- Reassembly, clearing and agreed basic operating checks
Requires separate confirmation
Repair work or site-dependent scopes
- Outdoor units, refrigerant, electrics, motors, parts or fault repair
- Blockages or repairs deeper inside walls, ceilings or downstream drains
- High-level or restricted access, fixed furniture, finishes or other trades
- IAQ measurement, certification, duct work, or health and performance conclusions
Separate cleaning, repair and maintenance
Cleaning addresses visible dirt and the agreed components;
faults and parts require separate checks
Photos and surface condition provide clues, not a diagnosis. If the unit is also not cooling, tripping, making abnormal noise, leaking persistently or showing an alarm, share the symptoms and history before deciding whether cleaning, repair or another assessment should lead.

The completion record should list each finished unit
and its cleaning scope
Handover content follows the quotation and site requirements. It should let you identify the units addressed, the scope actually completed, the reinstatement status, and any item requiring separate follow-up.
- 01Unit and location
List completed items by site, room, branch or equipment location.
- 02Actual work scope
Record the components addressed, inaccessible areas and items quoted for separate assessment.
- 03Reinstatement and checks
State the reassembly, clearing and agreed basic operating or drainage check.
- 04Exceptions and follow-up
Separate damage, faults, parts and other work that needs a further decision.
Frequently asked questions
Before requesting a commercial
wall-mounted split cleaning quotation
Can I request a quote with the total unit count only?
The count is a useful start, but unit types, locations, mounting heights, the areas below, available work period, access constraints, cleaning scope and handover needs all shape the quotation.
Does indoor-unit cleaning include the outdoor unit?
The outdoor unit is assessed separately against its location, access, isolation, condition and required work, then listed clearly in the quotation where applicable.
Will cleaning always resolve no cooling, leaks or odour?
No. Dust or drainage condition can be one factor, but faults, parts, installation, the surrounding environment or another system issue can also be involved. The symptoms and inspection findings determine the next step.
Can the work be phased or completed outside office hours?
You can propose a preferred available work period and sequence. We will review unit quantities, site rules, access, isolation, protection, drying, reinstatement and available resources, then confirm the practical programme.
How often should a commercial wall-mounted split unit be cleaned?
There is no single interval for every site. Use manufacturer information, operating hours, environment, equipment condition, maintenance history and site inspection to decide.
Provide the site, unit types and quantities,
together with the available work period
Start with your current list and photos taken from a safe position. We will use the unit locations, protection needs, work scope and handover requirements to identify what else is needed before quotation. If another issue is found during cleaning, we will explain what can be followed up during the visit and what should be arranged separately for inspection or repair.
