SERVICE DETAILS
Hitachi AC cleaning,Repair, Installation and Inspection
Hitachi AC cleaning is arranged according to the unit type, model and installation location. If the equipment has an auto-clean function, you need to distinguish the parts handled by that function from the scope of professional cleaning.
OVERVIEW
Overview
Hitachi AC cleaning, fault inspection, repair and installation arrangements. Hitachi AC cleaning confirms removable parts according to the actual window, split or ceiling model. See the applicable cleaning process, current price list, inspection fee, and the boundary between repair and installation.
KEY CHECKS
Key preparation points before arranging
Auto-cleaning is not the same as a full wash
First provide the function and model information, and confirm whether it is only for the dust filter or specified parts. You cannot assume the fan wheel, drain pan and drain pipe have been cleaned.
Condition of the unit body and windowsill
For a window unit, please provide the sill, support and removable space details; for a split unit, photograph the bottom and side positions of the unit for assessment of protection, water collection and dismantling arrangements.
Separate cleaning from fault inspection
If it is not cooling, icing up, or showing a fault at the same time, explain the symptoms first. Dust buildup is only one possible cause, and we cannot promise that cleaning will definitely rule out refrigeration or electrical faults.
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
Hitachi AC cleaning confirms removable parts according to the actual window, split or ceiling model. If the model has an auto-clean function, first check which parts it handles; that does not mean the blower wheel, cooling coil, drip tray and drain pipe are fully cleaned, and the condition still needs to be assessed.
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.
Provide the model and the display status for the auto-clean function or other modes, and explain whether the abnormal noise, dripping, or weak airflow appears when the unit is on or during the cleaning cycle. Normal operation and faults must be identified first; do not judge based on the function name alone.
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
For Hitachi repairs, first identify whether the issue involves airflow, drainage, controls or other components, then quote the repair and parts costs. A model with extra functions does not mean all parts can be handled in the same way; applicable information and accessories must be checked model by 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
For Hitachi replacement, first measure the unit size, window opening or indoor/outdoor unit location, and reserve space for panel operation and future maintenance. Installation method, power supply, drainage and copper piping must be checked against the new unit’s requirements, rather than relying only on the old unit’s horsepower to decide whether it can be directly replaced.
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
Hitachi has auto-cleaning—do I still need to check internal dust?
This must be judged according to the actual model and condition. The automatic function may not cover all parts and cannot replace inspection of the fan wheel, water collection and drainage points.
Enquire about LOHAS ParkWhat do I need to provide for Hitachi 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 Hitachi?
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.
