General AC cleaning,Repair, Installation and Inspection
Enquire about JanFor General AC cleaning, please provide the full brand and model label on the unit. The casing appearance alone is not enough to infer dismantling method, equipment age, or parts availability.
OVERVIEW
Overview
General AC cleaning, fault inspection, repair and installation arrangements. For General AC cleaning, first confirm the full model from the nameplate, then identify the indoor unit, outdoor unit and installation type separately. Check the applicable cleaning process, current price list, inspection fee, and the boundaries between repair and installation.
KEY CHECKS
Key preparation points before arranging
Take a photo of the brand and model on the unit
Check the indoor or outdoor unit nameplate for the model; if the name or model is unclear, take a photo of the full unit and the nameplate first, so that visually similar air conditioners are not mistaken for the same model.
Check the actual condition of the old unit first
If the casing is brittle, the frame is rusty, or there is already unusual noise, please explain this before cleaning. Whether dismantling and washing is suitable must be assessed based on the actual condition; do not assume the equipment can definitely withstand dismantling or can be repaired just because of the brand.
Outdoor location explained separately
The scope of indoor unit cleaning and outdoor radiator cleaning is different; confirm the accessibility of the outdoor unit, shared location and any additional charges first, and do not assume it is included in the basic cleaning.
Charges are based on the model; no separate brand pricing.
Household and commercial air conditioning use the relevant current price lists, with additional confirmation based on quantity, unit location and extra work; brand pages do not set unconfirmed prices or maintenance commitments.
Confirm services other than cleaning first
Repairs are first inspected to confirm the cause and quotation; installation is assessed based on the new or old unit, piping, drainage, and power supply scope. Factory authorization, specific parts, and capability for all models are not implied by this page.
CLEANING FIRST
AC Cleaning Scope and Work Arrangement
For General AC cleaning, first confirm the full model from the nameplate, then identify the indoor unit, outdoor unit and installation type separately. Dirt location, parts removal and water collection space will affect the cleaning arrangement. We do not apply the method for a different unit just because the appearance is similar; the outdoor heat exchanger must be confirmed separately.
Inspect first, then clean, and finally test the unit
- First record the condition of the unit, confirm the installation location, removable parts and scope of work, and protect furniture, goods and electronic devices under the unit
- Dismantle and clean the applicable parts according to the actual model and safety conditions, handle dirt build-up, water collection and drainage, and do not treat repairs as included in washing the unit
- After reassembling the parts, test run, check drainage and tidy the site; if there is any pre-existing fault or extra work, it will be explained and quoted first

ViewCommercialAC cleaning price listCleaning maintenance and pricing90-day cleaning maintenance is subject to the terms; pricing is based on model type and number of units
The cleaning service includes a 90-day warranty for problems caused by the cleaning service; dripping and leakage cases must first have the cause verified and the applicable terms confirmed at booking, and not all cases qualify for free repair.
The following are for reference by equipment type only, and do not mean the same brand or venue must use all of the above models. Basic cleaning is priced by model and unit count; outdoor condensers, steam add-ons, special locations and extra work are subject to eligibility checks, and no brand-specific or industry-standard price is created.

FAULT INSPECTIONAir Conditioner Inspection: Identify the Problem FirstIf no repair is carried out, a fixed HK$500 inspection/attendance fee applies; it can be waived from the repair fee if you proceed with the repair.
Please provide the indoor and outdoor unit labels and site photos, and state whether the issue is airflow, cooling, drainage or operating noise. If the label is hard to read, send a full view first. Customers do not need to climb out of the window to identify it; the equipment should be confirmed before arranging the proper inspection.
Inspection fee and safety reminder
After the technician visits for an inspection, if the customer does not proceed with the repair or does not accept the repair quotation, a fixed HK$500 inspection/attendance fee will be charged; this is a single charge and is not split into two separate charges.
If you notice a burning smell, smoke, repeated tripping, or water near electrical parts, stop using the equipment first. Do not keep restarting it or dismantle it yourself.
REPAIRAir conditioning repair: confirm the quotation first, then proceedProceed only after the quotation is confirmed; our repair service does not include warranty
General repairs are quoted based on the full model and inspection results, and not on a similar appearance or an abbreviated name. For older units that need parts, suitability and availability must be confirmed first; we do not promise that parts will always be available for every year or model.
Keep costs and maintenance separate
If you agree to proceed with repairs, HK$500 can be deducted from the repair fee; please check the deduction and amount payable when confirming the quotation.
Our repair service does not include a warranty, including repair parts and workmanship. Please understand the repair scope and fees before accepting the quotation.
Repair parts must be checked against model and supply. We do not guarantee that parts are available for all models or that same-day repair is possible. We will not treat refrigerant top-up as necessary before the cause is confirmed.
INSTALLATIONAC installation and replacementGeneral installation includes a one-year warranty, separate from the manufacturer's warranty; new power supply wiring and extra works quoted separately
When replacing a General unit, first check the size of the new and old units, outdoor heat dissipation, window frame or bracket, and the power supply and drainage. For large or difficult-to-move equipment, access must be checked first. Reuse of old parts and the dismantling/installation method must be confirmed on site, and brand prices are not applied directly as a blanket quote.
Quote separately for work beyond the basic scope
Pulling a new power supply from the main switch to the unit is not included; please provide the existing power supply location for the technician to assess and quote separately.
First confirm old unit removal, transport, copper pipes (the copper tubes through which the refrigerant flows), drain pipes, fixing and any extra work needed. General installation warranty and the manufacturer's product warranty are separate. Please see the installation service page for the full scope; special systems are not directly subject to general replacement terms.

QUESTIONS
Frequently asked questions
Can older General units be booked directly for dismantling and cleaning?
You may first inquire, but whether disassembly cleaning is suitable depends on the model, condition, fixed installation and work location. If there is obvious damage or a fault, please state it first for assessment.
Enquire about JanWhat should I provide for General AC cleaning?
Please provide a photo of the model label, the sticker showing the brand, model and unit serial number, a photo of the entire air conditioner, the quantity, indoor and outdoor locations, and the district. If you cannot find the label, you may first send a photo of the entire unit; no need to dismantle it yourself. If there is water dripping, insufficient cooling, unusual noise or a fault code, please state that as well.
Is this page an official repair centre for General?
This is not a statement from the original manufacturer or an authorised repair centre. This page provides service enquiry information for OPOExpert Air Conditioning. For original warranty, specified parts or specialised systems, please first confirm the applicable scope.
Are the inspection fee and the call-out fee charged twice?
After the technician visits for an inspection, if the customer does not proceed with the repair or does not accept the repair quotation, a fixed HK$500 inspection/attendance fee will be charged; this is a single charge and is not split into two separate charges. If repair is approved, HK$500 can be deducted from the repair cost; please confirm the deduction and the amount payable when confirming the quotation. Inspection does not include cleaning, parts or repair, and related work will only be arranged after the quotation is confirmed.
Is the warranty the same for repairs and installations?
Our repair service does not include a warranty, including repair parts and workmanship. Please understand the repair scope and fees before accepting the quotation. We provide a one-year installation warranty, covering brackets and leaks caused by glass sealing or sealant. For split units, it also covers refrigerant leakage caused by poor refrigerant-pipe connection; not all water leaks or refrigerant leaks are covered by installation warranty. The two services must not be mixed up; for the full scope and exclusions, please see the repair and installation service pages, and special systems must be confirmed separately.
